SQL Database Recovery to Handle Database Page Corruption

2011-04-12T02:52:00.000-07:00

Microsoft SQL Server uses numerous objects to effectively manage your valuable data within the database and a database page is one among them. MDF (Master Database File) or MS SQL Server database is internally divided into pages. Every database page includes one 96-byte header, which contains page related information such as page type, page number, free space, and page ID. When metadata structure corruption takes place, it usually fails to read the pages and cause data loss. Data loss is one of the most critical situations that a computer user may face. It puts you in need of comprehensive SQL Recovery solutions.

SQL Server database pages are very much prone to corruption and may leave your data unusable in a number of cases. The pages corruption might be the outcome of improper editing of MDF file. As a practical example of the problem, you may come across the subsequent error message while attempting to mount an SQL Server database:

“Could not read and latch page P_ID with latch type TYPE. OPERATION failed.”

You get this error every time you try to mount your database. This behavior makes your significant data completely inaccessible. In such critical situations, you are required to find out the root cause of this issue and then fix it using SQL database recovery solutions.

Reason:

The most frequent causes of this problem with Microsoft SQL Server database corruption can be any of the following ones:

• The page that you are trying to access is in the repairing state.
• SQL Server is performing an intermediate operation on particular page.
• The page is read as the part of every checks of significant SQL database system tables.
• The page is too damaged to be recognized by MS SQL Server.

You may face this issue due to either logical or physical MDF file corruption.

Solution:

Use any of the following MDF recovery solutions to work around this issue-

• Detect and fix consistency issues using DBCC CHECKDB command. It is an inbuilt SQL repair tool of SQL Server.
• Restore database from the latest backup.
• When both the above solutions fail to work, go for third-party SQL database recovery software.

SQL Recovery applications are helpful to scan whole database and recover SQL database in all corruption scenarios. They help you recover all database objects, including Tables, reports, forms, Macros, queries, constraints, and more.

SQL Recovery to Fix “Repair this error..” Error in SQL Server Database

2011-04-05T23:04:00.000-07:00

Microsoft SQL Server is an advanced RDBMS from Microsoft Corporation, which has three major versions- Microsoft SQL Server 2008, 2005, and 2000. It offers a wide range of features over the other database management systems, such as reliability, high-performance, and consistency. In order to check and fix consistency errors, it include DBCC CHECKDB tool. This is an inbuilt utility of the SQL Server that helps you perform SQL Database Recovery by fixing the common database problems.

DBCC CHECKDB is an advanced database maintainace command-line utility, which supports various parameters. You must follow the proper instructions while using these parameters, as some of the options may remove damaged data and cause complete data loss. DBCC CHECDB works in both physical and logical data problems. It provides errors that can be used to analyze the fix the problem.

However, under some circumstances, the command-line SQL recovery tool gives you error when it can not handle the problem. As an example of this problem with MS SQL Server database, consider the following error mesasge that occurs while scanning the database using DBCC CHECKDB command-

“Server: Msg 8905, Level 16, State 1, Line 0
Extent (1:6945928) in database ID 8 is marked allocated in the GAM, but no SGAM or IAM has allocated it.
Server: Msg 8905, Level 16, State 1, Line 0
Extent (1:6945936) in database ID 8 is marked allocated in the GAM, but no SGAM or IAM has allocated it.
Server: Msg 8905, Level 16, State 1, Line 0
Extent (1:6945944) in database ID 8 is marked allocated in the GAM, but no SGAM or IAM has allocated it.”

Subsequent to the above error message, you may also get the following error-

“Repairing this error requires other errors to be corrected first.”

To repair SQL database in such cases, you must first identify the root of the problem and then fix it using SQL recovery solutions.

Cause-

As stated in the above error messages, this problem occurs due to corruption to the SQL Server database. Corruption may occur after virus infection, unexpected system shutdown, application malfunction, and other similar reasons.

Resolution-

When DBCC CHECKDB cannot handle database corruption, SQL database recovery software come for your help. The SQL repair applications are designed to scan whole database using advanced scanning algorithms and handle all cases of corruption. Stellar Pheonix SQL Server Recovery is the most advnaced and comprehensive software to recover SQL database.

SQL Recovery to Handle Transaction Log Corruption in SQL Server

2011-03-17T02:10:00.000-07:00

Microsoft SQL Server records all the database transactions in transaction log. Transaction is an operation that you perform on the database that can be read, write, modify, or delete. However, in some situations, an SQL Server operation that requires to process or read transaction log may fail due to corruption. The corruption usually leads to data loss and put you in need of SQL database recovery solutions.

When the operation fails, you may encounter the below error message that indicates that transaction log is damaged-

Error: 9004, Severity: 21, State: 1.
An error occurred while processing the log for database 'mydb'. If possible, restore from backup. If a backup is not available, it might be necessary to rebuild the log.

The State number of the error may vary for the error and indicates what is the type of corruption. To sort out this problem and perform SQL recovery, you must find the cause of this issue.

Root of the problem-

Error 9004 usually occurs due to corruption to the transaction log of Microsoft SQL Server database. The causes for the transaction log inconsistency are similar to the database corruption issue detected in MDF (Microsoft Database File) by DBCC CHECKDB command or SQL Server Engine. In order to identify y the actual reason of the corruption, you must follow similar techniques for the database corruption including file system and hardware analysis.

Resolution-

As stated above in the error message, you are required to restore the database from the most recent backup to recover SQL Server database. This is the most efficient and easiest SQL Server recovery solution.

If you do not have an updated backup in place, then you should run DBCC CHECKDB command on the database. It is an inbuilt tool of SQL Server that checks and fixes database inconsistency issues.

In case none of the above methods work, SQL recovery software come for your rescue. Third-party SQL database recovery applications are totally safe and easy to use with read-only conduct and simple graphical user interface.

Such applications effectively handle all database corruption issues. They work with all sizes of the database of Microsoft SQL Server 2008, 2005, and 2000. In order to ensure absolute SQL repair, you are highly recommended to use an advanced tool, such as Stellar Phoenix SQL Server Recovery.

Sql Recovery When Filestream Corruption Damaged Sql Server Database

2010-10-25T04:51:00.000-07:00

When you try to restore the Microsoft SQL Server 2008 database (MDF file) from the sequence of transaction log backups, MS SQL Server 2008 database gets damaged. However, the original database, from which you took backup of the transaction log has not damaged. In these situations, the restore operation could not take place and thus your database become inaccessible and critical data loss situations occur. At this point, to gain access of your mission critical data, you are required to carry out SQL Recovery using appropriate solutions.

When the above problem of database corruption occurs, you might encounter the following event in the Application Event log of Microsoft SQL Server:

"Filestream corruption - missing files, error 7904.

The corruption is detected on a database that was restored from a sequence of backup logs. The original database does not seem to be corrupted.

7904 16 2 Table error: The filestream file for "FileID" was not found."

In above scenario, the data loss situations occur. In such cases, you get your valuable data back, you need to find out the cause of this problem and go for SQL Repair by sorting out this issue.

Grounds of the issue

This behavior of Microsoft SQL Server occurs due to filestream corruption. When it happens, the SQL Server database gets damaged as stated in above error message, and the database become inaccessible.

The Filestream is a critical SQL Server database component that integrates SQL Server Database Engine with NTFS file system by storing the varbinary(max) BLOB (Binary Large Object) data as the files on file system. Win32 file system interfaces offer streaming access to data. It uses NT system cache for data caching.

In all these cases, you encounter database corruption and need to go for SQL Recovery by repairing and restoring the database.

Recovery is best possible with the help of powerful and advanced third party applications, known as SQL Repair tool. They perform extensive scan of damaged database to extract all of the database objects such as tables, reports, forms, triggers and stored procedures.

These tools come equipped with interactive and simple graphical user interface and thus do not require sound and prior technical skills to carry out recovery process. With read-only behavior, they do not alter original contents of the database.

Getting table Error 8925 while working on MS SQL Server 2000 database?

2010-09-01T04:52:00.000-07:00

Are you getting some table errors while working on MS SQL Server 2000 database? At times, these errors appear because of database corruption, which can be caused due to various reasons including header corruption in the MDF (Master Database File) file, virus infections, etc. Such corruption issues can make the SQL database vulnerable and may make it inaccessible. In such cases, you should use a third-party SQL database recovery software if you are unable to recover SQL database using any workaround.

Let us have a look at a practical situation in which you are getting the following error message while working on a database table in MS SQL Server 2000:

“Table error: Cross object linkage: Page P_ID1, slot S_ID1, in object ID O_ID1, index ID I_ID1 refers to page P_ID2, slot S_ID2, in object ID O_ID2, index ID I_ID2.”

Cause:

The root cause of this problem is that the P_ID1 page points to a P_ID2 in a different object.

Resolution:

To address this erroneous situation, you should look to recover MDF file. This could be done by doing either of the following methods preferably in the given order:

Fixing the hardware related problems: You should try to resolve the reasons due to which the hardware parts may have become faulty. For this intent, the following measures can be taken:
- Checking the error logs to confirm that some error has not occurred because of any hardware related problem.
- Checking if write-caching is not enabled for the hard disks. If yes, then contact your hardware provider to the solutions.
- Installing the operating system again after formatting the hard disk.
Replacing updated backup with database: If the hardware parts are in perfect situation, then you should use the clean and updated backup to replace the database.
Running DBCC CHECKDB: Lastly, you should run the DBCC CHECKDB utility to recover SQL database with the suggested repair clause.

If the problem is persisting and you are still getting the table errors, then there is a need of recovering the SQL database. For this purpose, I would recommend using a third-party MDF file recovery software. Use of fast and sophisticated scanning algorithms, non-destructive SQL recovery, and rich user interface are some of the salient features of these tools.

How to Repair Corrupted MS SQL Server 2008 Database by Rectifying Error 2537

Are you facing problems while using MS SQL Server 2008 database? Then, there may be chances that the database may have got corrupt. The database corruption can occur due to various reasons such as virus infections, abrupt system shutdown when the database is open, hardware problems, etc. Due to database corruption, you would not be able to access the database or face abrupt behavior. In such cases, you should perform appropriate SQL repair methods to solve the problem. If you are unable to repair MDF file, then you should use a third-party MS SQL repair software to do the needful for you.

Consider a scenario wherein you encounter the following error message while working on an MS SQL Server 2008 database:

"Table error: Object ID O_ID, index ID I_ID, partition ID PN_ID, alloc unit ID A_ID (type TYPE), page P_ID, row ROW_ID. Record check (CHECK_TEXT) failed. Values are VALUE1 and VALUE2."

Cause:

The root cause of such behavior is that the ROW_ID row (mentioned in the error message) failed the condition asked in the CHECK_TEXT.

Resolution:

To resolve this situation, you should perform the following methods in the given order:

Resolve the hardware issues: You should check the error logs and run hardware diagnostics to see if it has occurred due to any hardware malfunctioning. You can also swap the hardware components to isolate the exact reason for the error. Lastly if nothing works out, then you can also consider reformatting the hard disks and reinstalling the operating system.

However, for doing this you should ensure that you backup valuable data.

Restore from backup: If the problem is not hardware related, then you should check the backup. If it is updated and clean, then you should restore the database from its backup.

Run DBCC CHECKDB: If the backup is not updated, then you should run the DBCC CHECKDB tool with the suggested repair clause. This tool will rebuild the index, if exists.

The problem will be fixed once you perform the aforementioned MDF file repair methods. However, if it is not so and the problem is persisting then you should use a third-party MDF repair utility to repair SQL database.

How to solve page header corruption cases in MS SQL Server 2008 database

2010-08-01T22:21:00.000-07:00

You must have experienced cases of database corruption more often than not. When you face database corruption, you are unable to work further on the database. These instances can occur due to any arbitrary reason. Some of the most prominent ones could be unplanned system
shutdown especially when the database is open, page header corruption, virus infections in the database, etc. You can repair SQL database by using few workarounds. However, if nothing works fine then using a third-party SQL repair software is the best option.

For instance, the following error message appears while you are working on an MS SQL Server 2008 database:

“Table error: alloc unit ID A_ID, page P_ID. The test (TEST) failed. The values are VAL1 and VAL2.”

Cause:

Such problem has happened as a database page, P_ID, has not passed auditing test because of page header corruption. You can refer to the error message where it is clearly shown that the TEST string has failed the test.

Resolution:

In such erroneous situations, you should try to address the issue by performing MDF file repair. For the same purpose, there are the following methods that should be performed, ideally in the exact given order:

Verify the hardware components: You should check the state of the hardware components by the following measures:

Check the SQL Server error logs to verify if there is any hardware related error.

Swap the hardware components to narrow down on the exact hardware error, if any.

Check if the disk controller has enabled write-disk caching. If yes, then take the assistance of the hardware vendor to sort this issue.

Format hard drive and reinstall fresh copy of operating system to get a fresh and clean system.

Reinstate database using backup: If the hardware components are alright, then check the state of the database backup. If it is updated, then replace the database with the backup.

Now, check the database after performing these methods. The problem would not be appearing any more. However, at times the database is so severely damaged that it is not repaired using these methods. In such cases, the use of third-party MDF repair tools is required. These tools repair SQL database without overwriting the actual database thus ensuring safe and secure SQL recovery.

In these situations, the most recommended MDF repair software is Stellar Phoenix SQL Data Recovery that repairs MDF file from any random instance of database corruption.

I/O Logical Check Failure Cause SQL Server Database Corruption

2010-06-13T23:22:00.000-07:00

Like other databases and files, Microsoft SQL Server database may also come across various corruption issues. The corruption can take place due to various reasons, including the internal database or SQL Server application issues and system related problems. One major system related problem, which can cause MDF (Master Database File) corruption, is I/O logical check failure. In such situations, the database becomes totally inaccessible and you come across severe data loss situations. In order to get your mission critical data back, you need to repair and restore the corrupt database using SQL database recovery solutions.

The I/O logical check failure can be indicated by various error messages, which includes the following one:

“Error 823
I/O error detected during at offset in file ''”

The above error may also occur when SQL Server come across other system errors. After this behavior, SQL Server database become totally unusable. In order to sort out this problem, you need to fix it through SQL recovery methods.

Cause

If the read Windows API (Application Programing Interface) call or writer API call for SQL Server database is successful, but some particular logical checks are unsuccessful. In such cases, error 823 occurs, which resembles the following:

“2003-09-05 16:51:18.90 spid17 Error: 823, Severity: 24,
State: 2
2003-09-05 16:51:18.90 spid17 I/O error (torn page) detected during read at offset 0x00000094004000 in file 'F:\SQLData\mydb.MDF'..”

Resolution

In order to work around this behavior of Microsoft SQL Server database and perform SQL Server recovery, you should first run DBCC CHECKDB utility on the affected or damaged MDF file. Before you try to fix any system related issue with MS SQL Server, you should first check the database and sort out the problems. If DBCC CHECKDB statement fails to detect or fix any error, please check the Application Event Log of Microsoft SQL Server.

If the above method fails to find and fix any errors in Microsoft SQL Server, you need to restore the database from a valid and recent backup to get your valuable data back. In case backup is not available, you have to opt for third-party applications to repair and restore the corrupted MDF file.

The repair mssql applications are particularly designed to methodically scan entire database and extract all inaccessible data from it. The software have read-only approach and simple graphical user interface to ensure safe and easy recovery.

SQL Recovery is the most efficient and powerful utility to ensure absolute recovery in all MDF corruption situations. It works well with Microsoft SQL Server 2008, 2005, and 2000. The software restores all MDF file objects, such as tables, reports, forms, macros, stored procedures, and triggers.

Rectifying Error 5242 and recovering corrupt database in SQL Server 2008

2010-06-10T05:26:00.000-07:00

A page is the most primitive unit of storage in an MS SQL Server database. The memory space allotted to a database file is divided into pages having contiguous address location. An Index Allocation Map (IAM) is a page type that stores the details about the extents used by a table per allocation unit. However, sometimes these pages do not function properly because of database corruption. You should take appropriate corrective measures to recover SQL database. However, if you are not able to restore the database then you should use a third-party SQL recovery software to do the needful for you.

Consider a scenario wherein you encounter the following error message while working on an SQL Server 2008 database table:

“An inconsistency was detected during an internal operation in database '%.*ls'(ID:%d) on page %S_PGID. Please contact technical support. Reference number %ld.”

Cause:

The root cause of this error message is that some inconsistency has occurred in the structure of the database page. It could have happened because of various reasons such as virus infections, abrupt system shutdown, hardware issues, etc.

Resolution:

To resolve this erroneous situation, you should perform either of the following methods, preferably in the given order:

Check for hardware issues: You should check the hardware components and the report logs to check whether the issue has occurred because of any hardware malfunctions. You should also swap the hardware components to isolate the error. Last but not the least, you can also consider reformatting the hard disks and reinstalling the operating system.

Restore from backup: If the issue is not hardware related, then you should check the backup of the database. If it is clean and updated, then restore the database from its backup.

Run DBCC CHECKDB: If the backup is not clean or updated, then you should run the DBCC CHECKDB utility without the repair clause to know the corruption level. Then, you should the run it with the suggested repair clause.

The aforementioned methods should be able to bring about the solution to the problem. However, if you are not able to repair the corrupted database then you should use a third-party SQL database recovery software to do the needful. Such read-only tools are able to recover SQL database using fast yet sophisticated scanning algorithms.

Stellar Phoenix SQL Database Recovery is an MS SQL recovery software that repairs the corrupted databases created in SQL Server 2008, 2005, and 2000. It is able to recover various database objects such as tables, queries, stored procedures, triggers, defaults, etc. In addition, this SQL server repair tool is able to recover the user-defined functions and data types. It is compatible with Windows 7, Vista, Server 2003, XP, and Server 2000.

Minimum Repair Option for the SQL Server Database Inconsistency Issues

2010-06-09T04:10:00.000-07:00

In Microsoft SQL Server, if any transaction violates the integrity constraints during execution, database inconsistency occurs. The transaction leaves your MS SQL Server database in illegal state and it gets aborted with an error. Database inconsistency leaves your MDF (Master Database File) in an unusable and inaccessible state, which can lead to serious data loss. In such cases, a valid and updated backup come for your rescue. You can easily restore all your valuable data from current backup and prevent needs of SQL recovery using third-party applications.

However, in case you are unable to restore data from the backup or backup is incomplete, you can check the database errors and fix them using inbuilt utility of Microsoft SQL Server, called CHECKDB. It offers you an option to repair the database errors. Database inconsistency may also occur due to system level errors, like file system and hardware. You are highly recommended to fix these errors before repairing the database, else you may face the same problem again after some time.

When you apply DBCC CHECKDB on your MDF file, a suggestion is provided for indicating what minimum repair option is required to fix all errors. Such messages may resemble the following:

“CHECKDB found 0 allocation errors and 15 consistency errors in database 'mydb'.
repair_allow_data_loss is the minimum repair level for the errors found by DBCC CHECKDB (mydb”

The database repair recommendation is minimum degree of repair to try resolving all the errors from DBCC CHECKDB. It doesn't mean that the operation is capable of actually fixing all the errors and recover SQL database. You should also keep in mind that not all the errors reported by DBCC CHECKDB, where repair_allow_data_loss is suggested, cause data loss.

However, some of the database inconsistency errors can cause severe data loss problems. You must run the repair process for determining if solution of a particular error is going to cause data loss. In order to find errors with a specific SQL Server database table, you can try running DBCC CHECKTABLE tool.

In case you run across database corruption and data loss due to any inconsistency error, MS SQL repair becomes need of hour.
You can easily repair and restore damaged MDF file of SQL Server using SQL Server recovery software. The applications use advanced scanning algorithm to provide assured recovery of all your valuable data.

Stellar Phoenix SQL Recovery is the best utility to ensure absolute recovery of inaccessible SQL Server database. The software works well with Microsoft SQL Server 2008, 2005, and 2000. It is capable of restoring all MDF file objects, such as tables, reports, forms, macros, triggers, stored procedures, data types, and constraints.

How To - Fix Stored Procedures Corruption in MS SQL Server?

2010-05-26T23:13:00.000-07:00

Are you encountering errors while executing stored procedures in Microsoft SQL Server database? Is stored procedure not producing correct outputs? The problem may occur due to corruption of the stored procedures. After corruption, the database may not function correctly and you will need to repair it. In some cases, corrupt stored procedures may even damage the database if they perform improper database functions. In both these cases, you need SQL Database Recovery applications to get your database repaired.

Stored Procedure is in fact a set of Transaction- SQL (T-SQL) statements, which are compiled in a single query execution plan. It works like a construct in programming languages. The stored procedure has a number of advantages, such as pre-compiled execution, enhanced security controls, reduced client/server traffic, effective reuse of programming abstraction and code, and many more.

You can use the stored procedure to run a sequence of the SQL statements on conditional logic. If the conditional logic and the SQL statements are written in stored procedures, they become a part of a single execution plan. However, in this case if any of the stored procedure gets damaged, you may come across a number of critical database corruption situations.

Corruption of the stored procedures may degrade the efficiency of MS SQL Server database and produce bad output. The function that needs to be executed using stored procedures might come down. This behavior usually makes the SQL Server database fragile. Stored procedure corruption may be indicated through a number of error message, similar to the following ones:

“Error 0:[SQL-DMO]Object 'dbo.SP_ProcName' was not scripted. It is possible that the information in system table 'syscomments' about the object was corrupt or missing?”

Or

“Incorrect key file ... try to repair it”

SQL Server database stored procedures may occur due to virus infection, improper system shutdown, application malfunction, improper command execution, and many alike. Irrespective of the cause of this problem, data loss occurs and SQL Recovery is required.

You can easily Recover SQL database with the help of third-party SQL Server Recovery applications. They come equipped with highly-advanced and efficient scanning techniques to ensure absolute recovery of damaged SQL database. The software are built-with simple and self-descriptive graphical user interface to provide ease of use.

Rectifying Error 5228 in SQL Server 2008

2010-05-26T04:14:00.000-07:00

When you use the DML (Data Manipulation Language) commands to update the database, the rows sometimes get in an intermediate state. It is called the antimatter state that enables concurrent DELETE statements to leave a pointer for the index builder transaction so that deleted rows are not inserted again. Ideally, these rows should be deleted at the end of the operation. However, sometimes it does not happen that invariably results in database corruption. To resolve this situation, you should use appropriate corrective methods. However, if you are unable to do so then you should use a third-party SQL Server recovery software to address the issue.

Consider a scenario wherein you are working on a table in SQL Server 2008. You get the following error message while performing some modifications on the database table:

“Table error: Object ID O_ID, index ID I_ID, partition ID PN_ID, alloc unit ID A_ID (type TYPE), page PG_ID, row R_ID. DBCC detected incomplete cleanup from an online index build operation. (Antimatter column value is VALUE.)”

Cause:

The root cause of this error message is that for the O_ID object , I_ID index, and PN_ID partition, there is an unfinished online index build was detected. This is testified by the presence and the displayed value of an antimatter column on the R_ID row.

Resolution:

To resolve this error message, you should perform the following methods, preferably in the given order:

Check for hardware issues: You should run the hardware diagnostics and check if the error appeared because of any hardware issue. You can also try to swap the hardware components to zero in and resolve the issue. In addition, you can try to reformat the disk and reinstall the operating system.

Restore from backup: Check if you have a clean and updated backup of the database. If yes, then you should restore the database with its backup.

Run DBCC CHECKDB: As a last resort, you should run the DBCC CHECKDB command without the repair clause to ascertain the level of the corruption. You should run the command again after knowing the repair clause. It will rebuild the corrupted indexes.

However, if you still are not able to resolve this error by any which method then you should use a third-party SQL recovery software. Such read-only tools are able to recover SQL database using sophisticated scanning algorithms without overwriting the original data.

Stellar Phoenix SQL Recovery is an MS SQL recovery software that enables you to recover corrupted databases created in SQL Server 2000, 2005, and 2008. It is competent enough to restore various objects of SQL database such as tables, queries, stored procedures, triggers, views, etc. This SQL recovery software is also able to preserve the database constraints and user-defined data types.

Resolving Error 5171 in SQL Database

2010-05-24T02:43:00.000-07:00

SQL database corruption can occur due to SQL Server malfunctioning, virus infection, improper system shutdown, hardware failure and many more. Once the MS SQL database gets corrupted, the SQL database become inaccessible. In such situations, use you backup, if there is no backup, the user needs to repair mdf file by using advanced SQL MDF Repair application. Consider a practical scenario, where a user is working on SQL Server 2005 and creating a report. While doing so, the Windows restarts due to power failure. When user restart the system, the SQL database becomes inaccessible. When the user tries to attach the MDF manually, he encounters the below error message:

“An exception occurred while executing a Transact-SQL statement or batch. _db.mdf is not a primary database file. (Microsoft SQL Server, Error: 5171).” Or

“C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data\MYDATABASE.mdf is not a primary database file. (Microsoft SQL Server, Error: 5171)” In such circumstances, the database administrators recommend to attach a single file. However, when the user uses sp_attach_single_db Stored Procedures, the user encounters the following error message:

“Server: Msg 5172, Level 16, State 15, Line 1 The header for file path……\.mdf is not a valid database file header. The PageAudit property is incorrect.”

The above error message encounters due to MDF file corruption. The above issue occurs when the MDF file header gets corrupted or some invalid information is inserted in the header file. All these situations result, inaccessibility of the SQL database. To ensure accessibility of the SQL database, the user needs to recover it by using the latest backup. But sometime user has not created any backup of its database or mdf file, then he needs to perform MDF repair. To do so, user needs to use efficient and effective MDF repair application. Such mdf file repair applications incorporate advanced and powerful scanning algorithms to repair the corrupted MDF file. The mdf recovery software perform systematic scan of corrupted MDF files, repair and restore them in their original format without altering any information.

Troubleshooting Error 8999 in SQL Server

2010-05-19T22:18:00.000-07:00

All the users connected to the SQL Server instance have access to a global resource called tempdb system database. This database holds temporary user objects, internal database objects, and row versions that result from data modification. At times, when some allocation checks are performed on this TEMPDB database, they may result in allocation errors and unexpected results. Since TEMPDB cannot be put in offline mode, no fixes are possible for allocation errors in this database. However, for rest of the SQL databases, you can perform MS SQL Repair using suitable tools and utilities.

For exemplifying the given problem, consider, you might start receiving unexpected database access problems in MS SQL Server database. To determine the exact cause of the problem, you run CHECKDB command and the below error message pops up:

“Database tempdb allocation errors prevent further CHECKNAME processing.”

This error message is recorded with error number 8999 and severity level 10.

Cause

The above error results specifically when the entire check operation terminates because of allocation error in TEMPDB.

If database is still corrupt, the root cause of corruption is hardware problems.

Solution

To resolve the issue, you should:

Diagnose the SQL Server™ error and Microsoft® Windows NT® system log for determining if the problem has actually resulted due to hardware problems. You can also run hardware diagnostics and fix related concerns by, swapping the hardware components or installing a new hardware system etc.

restore the database from the last available backup, if hardware issues have not been the problem.

Run DBCC CHECKDB and determine the extent of database damage, in case no suitable backup is present. Later, you can run the same command but with a suitable SQL Repair clause to fix database corruption. However, you should backup the database before executing database repair as data loss is likely.

Run MS SQL Repair software for repairing corrupted SQL database. These utilities generally repair the database after any type and extent of damage.

Repairing SQL Server master database – Error 3417

2010-05-10T22:44:00.000-07:00

SQL Server is a relational database management system (RDBMS) by Microsoft that is designed for the enterprise environment. It has got two primary query languages, T-SQL and ANSISQL. It provides you the flexibility to access your database from anywhere, be it from a data center, desktop, or from a mobile device. It also provides combined services to query, search, synchronize, report, and analyze the database records. However, at times it may happen that the SQL Server is unable to run. It may be possible that the master database has gone corrupt. This can be possible because of various reasons such as virus infections, human errors, power outages or abrupt system shutdown while SQL Server was open. In such cases, you should replace the corrupted database with its updated backup. However, if the backup is not updated then you should use a third-party SQL Database Recovery software to recover SQL database.

Consider a scenario wherein you have MS SQL Server 2008 installed on your system. When you log onto the SQL Server, you are unable to do so. An error message is displayed, that is:

“Cannot recover the master database. SQL Server is unable to run. Restore master from a full backup, repair it, or rebuild it. For more information about how to rebuild the master database, see SQL Server Books Online.”

Cause:
The cause of the mentioned error message is that the SQL Server is unable to start the master database. If the master or tempdb database cannot be mounted, SQL Server cannot run. It is quite possible that the master database has gone corrupt because of various aforementioned reasons.

Resolution:
To resolve this issue, you should, first of all, check whether there is an updated backup of the master database. If yes, then you should replace it with the corrupted database. However, if the database is not updated then you should use a third-party SQL database recovery software to perform SQL Recovery of the corrupted database. Such read-only tools are able to recover SQL databases using fast yet sophisticated scanning algorithms.

SQL Database Recovery is an SQL Server recovery tool that enables you to perform SQL database recovery of the corrupted databases. It is able to repair various database components such as tables, defaults, stored procedures, triggers, views, and rules. It can also repair user-defined data types and functions and also database constraints such as primary key, foreign key, unique key, and check. It is compatible with Windows 7, Vista, Server 2003, XP, and 2000.

Incorrect Updating of System Tables Cause Database Corruption in SQL Server

2010-05-03T21:13:00.000-07:00

When you create an MS SQL Server object, the properties of objects are known as metadata. SQL Server stores metadata in a special tables, known as System Tables. You can update these tables as per your requirement. It is quite easy to update system tables by defining the triggers. However, MS SQL Server automatically updates most of the system tables internally using inbuilt API. You should always create a complete backup of all the system tables, before you try to update them. If the update fails or you improperly update the table, your SQL Server database may get severely damaged and you need SQL Database Recovery to be fixed.

The system tables are automatically created by Microsoft SQL Server, when you create an object. For instance, Microsoft SQL Server 2000 stores all your data types and column names in the internal system table, known as 'syscolumns'. The metadata, stored in system tables, can be used to gather performance statistics, discover column and table differences and similarities while upgrading the database, and obtain lock information.

In Microsoft SQL Server 2005 and later versions, the System tables are hidden and cannot be queried like general database tables. These tables are restricted even for the user who have full Database Administrator privileges. Though, system tables are not accessible directly, but there are various inbuilt procedures and views to extract metadata from them.

After accessing the system tables and metadata, you can update them, if required. The update process can be used to add new options or to remove some existing options.

You should work safely while updating the system table. Incorrect or improper updating of SQL Server system tables may lead to severe problems, which might need to reinstall Microsoft SQL Server application. It may also damage the SQL Server database. There is no guarantee of successful updating. Before you prompt for updating system tables, you are highly recommended to create a good backup of SQL Server database.

In case SQL Server database gets damaged due to incorrect updating of system tables, perform SQL Server Recovery by restoring the database from backup.

If backup is unavailable, use MS SQL Recovery software to sort out the problem. The applications are specifically designed to thoroughly scan entire database and extract all inaccessible data from it. They perform simple and secure SQL Recovery with interactive design and read-only behavior.

SQL Recovery software repairs and restores damaged Microsoft SQL Server database in all cases of corruption. The software works well with MS SQL Server 2008, 2005, and 2000. It recovers all damaged SQL Server database objects, such as tables, views, reports, triggers, stored procedures, data types, and more.

SQL Server Instance Does Not Start After Restoring Model System Database

2010-04-30T03:14:00.001-07:00

Microsoft SQL Server holds a set of the system database that are required for options of Microsoft SQL Server instance. You should backup the system database after each critical update, to prevent database corruption. The system database backup must include model, master, and msdb. You can restore Microsoft SQL Server easily from backup, in the event of the system failure. However, in some situations, the SQL Server's MDF (Master Database File) file may become completely inaccessible after you restore a model system database from backup. It leads to critical data loss situations and requires SQL Database Recovery to work around the problem if backup is not updated.

In a practical scenario, you may not start an instance of SQL Server successfully, when you attempt to initialize any instance of MS SQL Server after restoring model system database using 'WITH NORECOVERY' option. Furthermore, you may come across the below error message in the application error log of Microsoft SQL Server at the same time:

“2003-04-18 09:37:38.85 spid5 Starting up database 'model'.
2003-04-18 09:37:39.24 spid5 Bypassing recovery for database 'model' because it is marked IN LOAD. 2003-04-18 09:37:39.65 spid5 Database 'model' cannot be opened. It is in the middle of a restore.”

This behavior of Microsoft SQL Server renders entire MDF database file inaccessible and serious data loss occurs. To retrieve data from affected database, you need to Repair SQL Server database file by fixing this problem.

Root of the problem

When the model system database is restored using 'WITH NORECOVERY' option, restore options leaves your SQL Server model database in unrecovered state. Thus, you can no longer use the model system database as expected. Due to the same, SQL Server may not function effectively.

Resolution

To sort out this behavior, clear 'Loading' status of model system database in instance of Microsoft SQL Server. In case the SQL Server database is severely damaged and model database is also affected, reinstall SQL Server application and restore database from updated backup.

If you do not have backup, use third-party MS SQL Recovery software to repair and restore the database into accessible and working state. The SQL Recovery applications use advanced scanning algorithms to systematically scan whole database and extract all inaccessible objects from it.

SQL Recovery is a powerful, yet easy to use and safe utility to ensure absolute recovery in all SQL Server database corruption scenarios. The software works well with Microsoft SQL Server 2008, 2005, and 2000. It restores all MDF file objects, such as tables, reports, forms, macros, constraints, stored procedures, and triggers.

Recovering Error 2575 in SQL Server 2008

2010-04-28T21:45:00.000-07:00

A page is the most basic unit of storage in SQL Server. The memory space allotted to a database file is divided into pages having contiguous address location. And these pages are, in turn, stored in extents, which are a collection of eight contiguous pages. The role of the extents is to effectively manage the pages. An Index Allocation Map (IAM) is a page type that stores the details about the extents used by a table per allocation unit. These are also used by SQL Server to traverse through a heap to locate the available space for new rows. However, sometimes these IAM pages do not function properly because of corrupted databases. A database can become corrupt because of virus infections, human errors, faulty hardware, power outages, etc. In such cases, you should consider taking appropriate measures to recover the database. However, if you are not able to repair the database then you should use a third-party application for MS SQL Recovery.

Consider a scenario wherein you receive the following error message when you try to mount your SQL Server 2008 database.

“IAM page P_ID1 is pointed to by the next pointer of IAM page P_ID2 in object ID O_ID, index ID I_ID, partition ID PN_ID, alloc unit ID A_ID (type TYPE) but was not detected in the scan.”

The error message states that the IAM page was found for the current index but it was not found for the next-page pointer.

Cause:
There could be two possible reasons for the aforementioned error message, either the reference of the metadata file missing or the header of the IAM page is corrupt. Because of this, the database has gone corrupt.

Resolution:
To resolve the issue, you can perform the following measures:
Look for hardware failures: Do check if this error is because of faulty hardware. Run hardware diagnostics and check the error logs and rectify the hardware-related errors, if any. You should also look to swap different hardware components if the database is getting corrupt frequently. Also, you can also contemplate using a new hardware system. However, this would mean formatting the hard disk and reinstalling the operating system, which is not required as it would erase the database as well.
Replace the corrupted database with a clean backup.
Run DBCC CHECKDB command without a repair clause to check the extent of the corruption. Then, run it again with the appropriate repair clause after determining it.

However, if you are still not able to repair the corrupted database then you should use a third-party SQL Server recovery application to recover SQL database. Such read-only tools perform SQL Recovery using fast yet sophisticated scanning algorithms without overwriting the damaged area.

SQL Recovery software is a robust tool that enables you to execute SQL recovery on corrupted SQL database components such as tables, defaults, stored procedures, triggers, views, and rules. It is also able to repair the database constraints such as primary key, foreign key, unique key, and check. The MS SQL recovery utility recovers corrupted databases that were originally created in MS SQL Server 2000, 2005, and 2008. The software is compatible with Windows 7, Vista, Server 2003, XP, and 2000.

Recovering corrupt index in SQL Server 2008 – Error 2530

2010-04-27T23:00:00.001-07:00

MS SQL Server uses indexes to quickly find the records when a query is executed. Actually the SQL Server uses the index in a similar way as you would read a book. If you want to search a particular topic, you do not have to traverse each and every page. You would just look for it in the index and open the page/section directly. Following the same pattern, an index has got keys that are built from one or more columns in the table and pointers that refer to the storage location of the queried data. Well-defined indexes can improve the system performance remarkably as the amount of data that is read to fetch the query result. However, at times the index can get disabled because of various reasons such as power surges, virus infections, human errors, etc. In such cases, you should consider taking appropriate actions to resolve the issue. However, if you are not able to address the issue then you should use a third-party SQL Database Recovery tool to repair SQL database.

Consider a scenario wherein you are working on SQL Server 2008 system when you encounter the following error message:
“The index "%.*ls" on table "%.*ls" is disabled.”

Cause:
This error message is displayed when the index is disabled. The DBCC command cannot proceed when the index is disabled. There could be following reasons for this:
You have disabled the index manually by using ALTER INDEX.
The index is disabled as the database is corrupt.

Resolution:
To resolve this error message, you need to either rebuild it or drop it and recreate it. To do this, you can perform the following methods:
1.First of all, enable the index by using either of the following methods:
ALTER INDEX statement with the REBUILD clause
CREATE INDEX with the DROP_EXISTING clause
DBCC DBREINDEX
2.Rerun the DBCC command.

However, if you still are not able to address the issue, it means that the database is corrupt. In such a case, you should consider using a third-party SQL repair application to SQL Recovery. Such read-only tools repair SQL databases without overwriting the original data.

SQL Recovery software is a robust tool that enables you to repair and restore database components such as tables, defaults, stored procedures, triggers, views, and rules. It is able to perform mdf repair for the databases created in SQL Server 2000, 2005, and 2008. It can also recover index, database constraints, user-defined functions, and user-defined data types. It is compatible with Windows 7, Vista, Server 2003, XP, and 2000.

Resolving 8905 and 8924 DBCC CHECKDB Failure Errors

2010-04-27T02:16:00.000-07:00

To resolve logical damages in MS SQL Server database, an easy way followed by most database users is to execute DBCC CHECKB (with appropriate repair clause). This command after checking the logical and physical integrity of the database, repairs the database to the maximum possible level. However, if the command fails to repair, then it displays a severity level (either 10 or 16) error message(s). This error message helps the user identify the exact cause of database corruption. After any of the above error message(s) appears, the data saved in the database becomes inaccessible. To access the records in such cases, the user needs to restore the database records from an updated backup. But, in case no backup is available or backup falls short of restoring the database records, the database users need to repair the database using an efficient SQL Database Recovery application.

The above scenario can be explained with the help of the below error message:

“Server: Msg 8905, Level 16, State 1, Line 1
Extent (1:886000) in database ID 37 is marked allocated in the GAM, but no SGAM or IAM has allocated it.
Server: Msg 8905, Level 16, State 1, Line 1
Extent (1:886112) in database ID 37 is marked allocated in the GAM, but no SGAM or IAM has allocated it.
…
Repairing this error requires other errors to be corrected first.
Repairing this error requires other errors to be corrected first.
Repairing this error requires other errors to be corrected first.
...”

This error message appears when the user executes a DBCC CHECKDB command to repair his/her logically corrupted SQL Server 2000 database. Additionally, the same error message appears every time you try to repair your database.

Cause:

The above error message appears when the SQL Server 2000 database corruption is beyond the repair capabilities of DBCC CHECKDB command.

Resolution:

To resolve the above error message and to access the database records, the user needs to follow the below steps:

Restore database from an updated, valid, and complete backup.
Use a third-party SQL Database Repair application in case no backup is available. A commercial MS SQL Recovery utility can repair any logically damaged database, even if it cannot be repaired by DBCC CHECKDB command.

Stellar Phoenix SQL Recovery repairs MS SQL Server 2008, 20005, and 2000 database damaged due to logical crash. The SQL Repair tool is absolutely safe. It can be installed on Windows 7, Vista, 2008, XP, 2003, and 2000.

DBCC CHECKTABLE Doesn't Work on a Table That Has Corrupted Indexes

2010-04-25T21:46:00.000-07:00

Microsoft SQL Server stores all your valuable data in the MDF (Master Database File) in the form of tables. You can access data from the SQL Server database tables, using SQL queries. Under some circumstances, the database tables become inconsistent and you cannot access data from it. This behavior of MS SQL Server leads to significant data loss situations. At this point of time, you must have absolute backup of the database to restore the data from. However, if the backup is not available or not updated, you are required to use MS SQL Recovery applications to extract inaccessible data.

When you run the DBCC CHECKTABLE command on MS SQL Server database table to check the consistency and integrity of the table, you may come across the below error message:

“[Microsoft][ODBC SQL Server Driver][Named Pipes]ConnectionCheckForData (PeekNamedPipe()).
[Microsoft][ODBC SQL Server Driver][Named Pipes]Connection broken.”

The table checking gets terminated with this error. The error message occurs in the SQL Server database table, which has damaged indexes. The table remains inaccessible after this error message and you need to Recover SQL database to extract data.

DBCC CHECKTABLE is an in-built command-line utility in Microsoft SQL Server, which is used for checking the consistency and integrity of all structures and pages, which make up the indexed view or table.

Cause

You may come across this behavior of Microsoft SQL Server due to severe corruption in the SQL Server database table. The table corruption may occur due to numerous reasons, such as virus infection, application malfunction, unexpected system shutdown, hardware problems, operating system malfunction, and more.

Resolution

Try out the below steps to sort out this problem:

Obtain the latest service pack of Microsoft SQL Server. It helps you to prevent this problem from being occurred in future.
Drop all the automatically created statistics.
Restore SQL Server database from the most recent backup.
Repair and restore the damaged SQL Server database using powerful and advanced third-party applications, known as SQL Server Recovery software.

The SQL Server Recovery applications are particularly designed to carry out in-depth scan of entire SQL Server database using high-end scanning techniques and extract all inaccessible data from it. The software has read-only conduct and rich graphical user interface to ensure quick, safe, and easy recovery in all cases of SQL Server database corruption.

SQL Recovery software repairs and restores Microsoft SQL Server database in an absolute way. The software works well with Microsoft SQL Server 2008, 2005, and 2000. It restores all damaged objects of Microsoft SQL Server database, such as tables, reports, forms, macros, view, constraints, triggers, and stored procedures.

Recovering SQL database from the Error: 0x80004005 E_FAIL Minor error

2010-04-22T22:41:00.001-07:00

Those of you who are working with SQL Server database in your organization must be knowing how the database grows with time. The database files can grow quickly, which sometimes hampers the performance of the system. Moreover, the internal structure of the database may get fragmented with time that eventually result in wastage of the disk space. To remove the fragments and make the system faster, you should use Compact and Repair utility in SQL Server. However, sometimes when you try to access the database, it does not open as intended and throws some error message. In such cases, you should take appropriate measures to address the issue. It may be possible that the database is corrupt. Then, you should replace it with updated backup. And if the backup is not available, then you should consider using a third-party SQL Recovery tool.

Consider a scenario wherein you are working on a database and you have tried to open a connection in the Query Analyzer. The connection fails and an error message is displayed, that is:

“Error: 0x80004005 E_FAIL
Minor Error: (25017)
Description: Unspecified Error”

A Microsoft embedded Visual Basic (eVB) application that uses CompactDatabase method is not able to compact a corrupted SQL Server CE database.

Cause:

The root cause for this error message is that the database that you are trying to compact is corrupt. This can be inferred from the fact that when CompactDatabase utility is used, the ActiveX code tries to initialize the source database before compacting it. If the initialize fails, CompactDatabase aborts. Hence, you cannot use CompactDatabase on a corrupted database because the Initialize method on a corrupted database always fails.

Resolution:

To resolve this issue and recover SQL database, you should obtain the latest service pack for Microsoft SQL Server 2000 Windows CE Edition. If the issue is not resolved, you should use a third-party SQL Database Recovery tool. Such tools employ fast yet sophisticated algorithms to scan damaged area for performing MS SQL recovery.

SQL Recovery software is an efficient tool that can perform SQL server recovery on the databases created in MS SQL Server 2008, 2005, 2000. It is able to recover various database components such as identity, rules, tables, indexes, defaults, stored procedures. This SQL recovery tool can also recover database constraints such as primary key, foreign key, unique key, check, etc. It is compatible with Windows 7, Vista, 2003 Server, XP, 2000.

Recovering database from corrupt filegroups in SQL Server – Error 2522

2010-04-21T23:42:00.000-07:00

If you are a database backend user in your organization, then you must be knowing how the size of the database increases immensely within a span of a few months. If yours is a growing organization, then the issue gets even more aggravated as you have to regularly maintain the database. For this purpose, SQL Server 2005 provides various options to support database growth. One of them is creating a filegroup that can loosely be termed as a logical storage unit containing the database objects that map to a file system file or multiple files. In this, additional disk drives are allocated to support estimated growth of the database. Then, the additional files can be shifted to these filegroups to spread the I/O over additional disks. However, even the filegroups-supported database can get corrupt due to various reasons. In such cases, you should replace corrupt database with its updated backup. However, if the backup is not available then you should consider using a SQL Database Recovery tool.

Consider a scenario wherein you have received the following error message when you open the SQL database:
“Unable to process index I_NAME of table O_NAME because filegroup F_NAME is invalid.”

The aforementioned message states that the index cannot be checked as one of the filegroup IDs, which is stored in the index metadata, does not exist.

Cause:
The root cause of this error message is that the filegroup IDs stored in the metadata for an index do not exist so that index can not be checked. It may be possible that the database is corrupt.

Resolution:
To start off, you should check whether this error message is because of some hardware failures. You should run the hardware diagnostics, check the SQL Server error log, etc. If the error is not hardware-related then you should replace the database with an updated backup. However, if you do not have the backup then you should consider using a third-party SQL Server recovery tool to Recover SQL database.

SQL Recovery software is a robust tool that can perform SQL recovery on the databases created in MS SQL Server 2008, 2005, 2000. It employs fast and complex algorithms to scan the damaged area to repair the databases. The SQL database recovery tool is able to recover various database components such as identity, rules, tables, indexes, defaults, stored procedures. It can also recover database constraints such as primary key, foreign key, unique key, check, etc. It is compatible with Windows 7, Vista, 2003 Server, XP, 2000.

How to resolve Error 2501 in SQL Server?

2010-04-20T21:34:00.000-07:00

A lot of users prefer using MS SQL Server as the Relational Database Management System (RDBMS) both at their home as well as their workplace. This is so because it is a robust RDBMS, which is designed to conform to the enterprises environment, organizations, and high-end users with their advanced needs. However, sometimes the SQL database file (.MDF) may get corrupted due to various reasons such as virus infections, software failure, improper shut down while database is open, etc. In such cases, you should replace corrupted database with its updated backup. However, if it is not available then you should consider taking appropriate measures to SQL Recovery Server database.

Consider a scenario wherein you are working on a SQL Server database that is the master database of your organization. You try to open one of the tables but it fails to open and gives an error message, that is:

“Could not find a table or object named '%.*ls'. Check sysobjects.”

The aforementioned error message signifies that the table has become corrupt and, therefore, you cannot access the database records.

Cause:
The root cause of this error message is that the table specified in the DBCC CHECKTABLE was not found. It may have happened that the table did not exist or the metadata of the database was corrupt.

Resolution:
There are following measures that you can take in such situations:
First of all, make it a point to check if the table exists or not.
Replace the corrupted table with its updated backup.
Run DBCC CHECKDB without a repair clause to find out the effect of the data corruption. DBCC CHECKDB will recommend a repair clause to use. Then, use the recommended repair clause with DBCC CHECKDB.

If all the aforementioned measures are unable provide the SQL Database Recovery, then you should use a third-party MS SQL recovery tool. These read-only tools are highly interactive, and enable you to repair and recover the database components using sophisticated scanning algorithms.

SQL Recovery software enables you to repair and recover all the SQL components such as tables, rules, views, stored procedures, indexes, Defaults, Triggers, etc. In addition, it can successfully repair user defined functions and data types. It can repair the databases created in MS SQL Server 2008, 2005, 2000. It is compatible with Windows 7, Vista, 2003 Server, XP, 2000, and NT.

How to resolve the Error 8948 in MS SQL Server 2000?

2010-04-19T21:44:00.001-07:00

MS SQL Server is a Relational Database Management System (RDBMS) that is well designed to conform to the advanced needs of enterprises environment, organizations, and high-end users. It provides various tools to ease the burden of database development, maintenance and administrations. One of them is Page Free Space (PFS). It is a page in the database that searches for free space in the table. It contains a byte-map that holds one byte per page (P_ID), approximately 64 MB, in a PFS. However, sometimes P_ID is assigned to a PFS and you are not able to access the page. In such cases, the database becomes inaccessible and may get corrupt. You should replace the database with updated backup. If the updated backup is not available, then you should use an SQL Database Recovery tool to recover SQL database.

Consider a scenario wherein you encounter an error message when accessing a database table in MS SQL Server. The error message is:
“Database error: Page P_ID1 is marked with the wrong type in PFS page P_ID2. PFS status 0xVAL1 expected 0xVAL2.”

After encountering the aforementioned error message, you are unable to access the table or perform any other operation on it.

Cause:
The error message may have occurred because the bits are not set correctly in the database table, given the type of page and context in which it is read.

Resolution:
To resolve this issue, you can take the following measures:
Run hardware diagnostics and see if the data corruption is because of hardware failure. Try different hardware configurations to check if it is because of any hardware failure.
Replace the database table with its updated backup.
Run DBCC CHECKDB without a repair clause to find out the effect of the data corruption. DBCC CHECKDB will recommend a repair clause to use. Then, use the recommended repair clause with DBCC CHECKDB. The idea behind using DBCC CHECKDB is to set the PFS byte to the correct free space bits and to set them appropriately.

However, if you are not able to do SQL Recovery using the aforementioned measures then you should use a SQL database recovery tool. These read-only tools are highly interactive and employ complex algorithms to scan the damaged area to recover it.

SQL Recovery software is able to repair all the SQL components such as tables, rules, views, stored procedures, indexes, Defaults, Triggers, etc. In addition, it can successfully repair user defined functions and data types. This sql database recovery tool can repair all the databases created in MS SQL Server 2008, 2005, 2000. It is compatible with Windows 7, Vista, 2003 Server, XP, 2000, and NT.

SQL Server Can Not Recognize MDF File After Improper System Shutdown

2010-04-19T00:24:00.001-07:00

MDF (Master Database File) is the repository of all valuable data in the Microsoft SQL Server. Data is stored in the form of tables. However, in some situations, improper system shutdown may make your database faulty and inaccessible. This is because unexpected shutdown may damage the database. Microsoft SQL Server can not read the corrupted database and thus you face data loss. In such critical situations, you need to opt for SQL Database Recovery solutions if the backup is not updated.

Improper system shutdown may occur due to numerous reasons, such as system crash, power outages, application freezing, unresponsiveness of the system, and more. As a practical example of this problem, you may encounter the below error message when you reboot your system after an unexpected system shutdown and try to attach the MDF file manually:

“TITLE: Microsoft SQL Server Management Studio Express
Failed to retrieve data for this request.
(Microsoft.sqlserver.Express.smoenum)
For help, go to Microsoft help

ADDITIONAL INFORMATION: An exception occurred
while executing a Transact-SQL statement or batch.
(Microsoft.sqlserver.Express.connectioninfo
D:\Data\MSSQL\ISEC.mdf is not a primary database file.
(Microsoft SQL Server, Error: 5171) For help, go to Microsoft help

After this behavior of Microsoft SQL Server, you can not access the database. It results in severe data loss. In order to access your valuable data, it is essential to identify the root of the problem and perform SQL Server Recovery by resolving it.

Cause

Microsoft SQL Server can not read the damaged MDF file. In such cases, the problem occurs when SQL Server attempts to read data from damaged files and fails. Corruption is caused by improper system shutdown, which damages critical data structures and important system files of SQL Server database.

Resolution

You can work around this problem by restoring the damaged MDF file from an updated backup. Backup is the redundant copy of the database, which is maintained to prevent data loss. However, if the database backup is either not updated or is damaged, you need to use third-party SQL Recovery software to restore your database.

The applications are specifically designed to carry out in-depth scan of entire database and extract inaccessible data from it. They do not demand sound technical skills due to their simple and interactive user interface. Such tools perform safe SQL Recovery owing to their read-only conduct, by virtue of which they apply complex algorithms to read data from the original file. This data is simultaneously saved in a newly created file, thus leaving the original file intact.

SQL Recovery software repairs and restores damaged SQL Server database in all cases of corruption. The software works well with Microsoft SQL Server 2008, 2005, and 2000. It restores all MDF file objects, such as tables, reports, forms, macros, stored procedures, triggers, and more.

Fixing “The low key value on page P_ID1...” Error

2010-04-16T21:28:00.001-07:00

The physical storage of data stored in a MS SQL Server table can either be performed in a B-tree or heap structure. The B-tree structure consists of a two types of pages – parent page and child page. The parent page contains at least two child pages and keeps a record of every child page. In case the child page is at the last level (leaf-level), then all the records on that page should contain key values equal to or greater than the key value in the parent page. However, in case the child page is at tree level, then the key values should be greater than the key value in parent page. But, if these key values are not in accordance, then you might receive an error message that stops you from accessing its records. This mainly happens when the MS SQL Server database is logically or physically damaged. In such situations, you need to repair the database using a commercial SQL Database Recovery, if you have not maintained any backup.

Consider a practical case wherein you encounter the below error message while trying to access your MS SQL Server table:

“Table error: Object ID O_ID, index ID I_ID. The low key value on page P_ID1 (level LEVEL) is notCOMPARISON the key value in the parent P_ID2 slot S_ID.”

This is a severity level 16 error message. After the above error message pops up, the records saved in the table become inaccessible.

Cause:

The above error message appears due to corruption of MS SQL Server database.

Resolution:

To fix the above severity level 16 error message and to access the table records, you will need to follow the below steps:

View the system, application, and SQL Server logs, to identify physical corruption. After the damaged component is identified in the logs, change the component.

To identify logical damage, you will need to run DBCC CHECKDB command without a repair clause. After identifying the level of logical damage, run the same command with a suitable repair clause. However, if the error message persists even after running the above command, then you need to repair your database using an effective third-party SQL Database Repair application. Such SQL Recovery tools use effective repair techniques to repair logically damaged databases.

SQL Recovery is one powerful SQL Repair tool to repair MS SQL Server 2008, 2005, and 2000 databases. The software allows the database administrator to preview the repaired database before saving it at required location. It is designed for Windows 7, Vista, 2008, XP, 2003, and 2000.

DBCC CHECKDB Process Fails With “Error 8967” in SQL Server

2010-04-15T23:06:00.000-07:00

Microsoft SQL Server is a widely used relational database management system, which stores all the data in MDF (Master Database File). It provides an inbuilt utility to check the physical and logical integrity of the objects in specified database through a series of operations. However, in some situations, this tool fails to check the integrity and consistency of the SQL Server database and the database remains inaccessible. In such situation, you may face critical data loss situations and need SQL Database Recovery.

As an example of this problem, consider the underwritten scenario:

You restore Microsoft SQL Server 2005 or Microsoft SQL Server 2008 database from backup.
You encounter errors while restoring the database and the restore process fails.
You restore database from same backup using CONTINUE_AFTER_ERROR option.

In such cases, when you use DBCC CHECKDB command-line utility on computer, which has MDF file, you get the below error:

“Msg 8967, Level 16, State 216, Server , Line 2
An internal error occurred in DBCC which prevented further processing. Please contact Customer Support.
DBCC results for ''.
Msg 8921, Level 16, State 1, Server , Line 1
Check terminated. A failure was detected while collecting facts. Possibly tempdb out of space or a system table is inconsistent. Check previous errors.”

Furthermore, you may see the below error in error log of SQL Server:

“2007-05-26 07:13:49.21 spid58 DBCC encountered a page with an LSN greater than the current end of log LSN () for its internal database snapshot. Could not read page (file id:page id), database '), LSN = (), type = 32, isInSparseFile = 1. Please re-run this DBCC command.”

Cause

You face this problem if DBCC CHECKDB command can't perform required checks for confirming database consistency due to severe corruption.

Solution

In such critical situations, you need to restore database from the latest backup. But, if the backup is either not available or not updated, SQL Server Recovery becomes need of hour.

You can recover your damaged SQL Server database using powerful MS SQL Recovery software. The applications are powerful enough to systematically scan whole database and extract all inaccessible objects from it. They offer easy SQL Recovery with simple and interactive user interface.

SQL Recovery software successfully repairs and restores damaged SQL Server database using powerful techniques. It is designed for Microsoft SQL Server 2008, 2005, and 2000. The software restores all of the MDF file objects, including tables, reports, forms, macros, stored procedures, and triggers.

CompactDatabase Process Fails on a Damaged MS SQL Server Database

2010-04-13T22:39:00.000-07:00

Microsoft SQL Server is a popular relations database management system. It stores all your valuable data in the MDF (Master Database File). In case of corruption of the MDF file, due to virus infection, improper system shutdown, and other such reasons, the database become totally inaccessible. This behavior of MS SQL Server leads to significant data loss. In some cases of corruption, you can not even run the repair utility or open database connections after corruption. In such situations, you need to restore database from backup. If the backup itself is corrupt, SQL Database Recovery is required to sort out the problem.

In a practical scenario, you may get the below error message on a damaged SQL Server database in Microsoft SQL Server 2000 Windows CE Edition Query Analyzer when you try to open any connection:

“Error: 0x80004005 E_FAIL
Minor Error: (25017)
Description: Unspecified Error”

The error code in this error is SSCE_M_DATABASECORRUPTED (the SQL Server database file is corrupted or it is a Non-database file)

A eVB (Microsoft embedded Visual Basic) application, which uses CompactDatabase method isn't capable of compacting the damaged Microsoft SQL Server CD database. When you attempt to call CompactDatabase method, you may come across the below error message:

“Error: -2147467259
Compact”

To recover inaccessible data from the SQL Server database in such situations, you need to identify the root of the problem and then resolve it through SQL Server Recovery tools.

Cause

You may face this problem due to severe database corruption. Engine ActiveX code for the CompactDatabase attempts to start source database prior to compact source database. In case the start process fails, CompactDatabase process aborts. Thus you can't use CompactDatabase method on damaged database as the initialization method on damaged database fails in all situations.

Resolution

To prevent this problem from occurring in future, obtain latest service pack of Microsoft SQL Server. To fix the current database corruption problem, repair and restore the database using powerful third-party SQL Recovery software.

The applications are very easy to use with simple and rich graphical user interface. They do not demand sound and prior technical skills to perform SQL Recovery. With read-only and non-destructive conduct, these tools preserve integrity of your database.

SQL Recovery software repairs and restores damaged SQL Server database in all corruption scenarios. The software works well with Microsoft SQL Server 2008, 2005, and 2000. It restores all MDF file objects, such as tables, reports, forms, macros, stored procedures, constraints, and triggers.

Damaged Transaction Log Files May Cause SQL Server Database Corruption

2010-04-11T23:12:00.000-07:00

In Microsoft SQL Server 2005 and Microsoft SQL Server 2000, every database includes at least one transaction log file and data file. MS SQL Server stores data physically in data file and details of the modifications that are performed on SQL Server database are stored in transaction log file. Logging the transaction details can't be turned off because transaction integrity is conceived an intrinsic and fundamental characteristic of MS SQL Server. In case of corruption or loss of transaction log file, you may come across SQL Server Database corruption. In such cases, you are required to perform SQL Database Recovery to retrieve data.

To prevent database corruption, one must prevent unexpected growth of transaction log files. To do so, follow the underwritten steps:

Set size of transaction log files to a large value for avoiding automatic expansion of transaction log files.
Configure automatic expansion of the transaction log files using memory units instead of percentage after evaluating optimum memory size.
Change recovery model. In case of data corruption or some disaster, you need to recover damaged database so you can maintain transaction integrity and data consistency of MS SQL Server database. Depending upon the significance of damaged database, you can go for any of the following database recovery models for determining how the data and information is backed up and what exposure you have to data loss:

Simple recovery model - To recover corrupt SQL Server database to most recent backup.
Full recovery model - Enables you to recover damaged database to a point when database failure occurred. It restores database using transaction log files.
Bulk-logged recovery model - It works in the same way as the Full recovery model does.

Backup transaction files regularly.
Do not continue running the uncommitted transactions.
Defragment indexes.

In case the above methods can not help you, and transaction log file gets damaged, you may face severe database corruption. In such situations, MS SQL Recovery is the only way to repair and restore damaged database.

The MS SQL Recovery applications use advanced database scanning techniques to thoroughly scan the damaged database and extract all data from it. They Recover SQL database in a safe and easy way with their read-only conduct and interactive graphical user interface.

SQL Recovery software safely repair and restores damaged SQL Server database in all cases of corruption. The software works well with MS SQL Server 2008, 2005, and 2000. It restores all damaged and inaccessible database objects, such as tables, reports, forms, macros, triggers, and stored procedures.

Tips to resolve “Page P_ID1 was not seen in the scan...” Error Message

2010-04-08T21:35:00.000-07:00

Tables in MS SQL Server contain thousand of records that are contained in more than one partitions. These partitions save data rows in either B-tree or heap structure. The table records saved in B-tree can be retrieved faster than in heap tree. The reason behind fast retrieval is that the data pages in B-tree are connected in a doubly-linked list. While the navigation process is faster in B-tree structure, the process might halt if any child page points to a wrong index page or is not pointing to any page. Such situations primarily occur when your database is corrupted. In such circumstances, a database user encounters an error message that makes the data saved in the table inaccessible. To access the records in such cases, the user can restore table from an updated backup or run DBCC CHECKDB command. However, if both the parameters fail to resolve, then the user needs to opt for a commercial SQL Database Recovery product.

Consider a practical example to elaborate the above problem where you encounter the below error message while accessing a MS SQL table:

“Table error: Object ID O_ID, index ID I_ID. Page P_ID1 was not seen in the scan although its parent P_ID2 and previous P_ID3 refer to it. Check any previous errors.”

This is a severity level 16 error message, that pops up and does not allow you to access the table records.

Cause:

The above error message appears when a child page (P_ID1) can not be seen even though the index page is pointing to the child page. This above situation occurs when the database is either logically or physically corrupted.

Resolution:

Corruption due to physical damages can be resolved by changing the damaged system component.
Corruption owing to logical reasons can be rectified by running DBCC CHECKDB command. But in case, the error message persists after executing DBCC CHECKDB command, then you will need to use third-party MS SQL Recovery tool to repair your table. Such SQL Repair application scan the database and repair it to the fullest.

SQL Recovery application is used to repair logically corrupted SQL database, regardless of its cause of corruption. The SQL Database Repair tool supports repair of every SQL Server database component built in MS SQL Server 2008, 20005, and 2000. It supports Windows 7, Vista, 2008, XP, 2003, and 2000.

False Positive and Database Consistency in Microsoft SQL Server

2010-04-06T21:54:00.000-07:00

Are you facing various instances of the 'False Positive' on your Microsoft SQL Server when you run DBCC CHECKDB statement for checking database consistency? The problem may occur due to inconsistency of the MDF (Master Database File) of MS SQL Server. Database inconsistency can be due to numerous reasons, such as database corruption, missing database objects, and more. In all such cases, the database becomes completely unusable and you face severe data loss problems. In such circumstances, it becomes essential to perform SQL Database Recovery to overcome the problem.

For instance, when you run DBCC CHECKDB statement on your SQL Server database, it gives consistency errors in database tables. However, if you run DBCC CHECKTABLE statement to repair the table and fix inconsistency problems, it does not display any errors. When you face a false positive situation, you get either of the below errors:

“DBCC CHECKDB is performing an exhaustive search of indexes for possible inconsistencies.”

Or

“SQL Server has encountered 1 occurrence(s) of I/O requests taking longer than 15 seconds to complete on file in database .”

At the same time, Application Event Log of MS SQL Server may contain entries similar to the following ones:

Msg 8978, Sev 16, State 1, Line 1 : Table error: Object ID 1789795471, index ID 1, partition ID 72057602467495936, alloc unit ID 72057602585395200 (type In-row data). Page (1:2387522) is missing a reference from previous page (1:2387521). Possible chain linkage problem. [SQLSTATE 42000]
Msg 8958, Sev 16, State 1, Line 1 : repair_allow_data_loss is the minimum repair level for the errors found by DBCC CHECKDB . [SQLSTATE 01000]

Cause

The problem occurs due to inconsistency or corruption in the MDF file. It may be due to unexpected system shutdown, virus infection, and other such reasons.

Resolution

You can get your database in working state by restoring it from an updated backup. After restoring the database, you must run database defragmentation. However, if the backup is not current, then only SQL Server Recovery can help you to extract inaccessible data.

Effective and absolute recovery is possible with SQL Recovery software. These are powerful third-party tools, which scan whole database and retrieve all damaged and inaccessible data from it. You need not have sound technical skills to use these MS SQL Recovery software as they have simple graphical user interface.

SQL Recovery is the most advanced utility that ensures perfect recovery of damaged SQL Server database. The software repairs and restores MDF files of Microsoft SQL Server 2008, 2005, and 2000. It recovers all SQL Server database objects such as tables, reports, forms, triggers, and stored procedures.

Fixing “Could not repair this error” Error

2010-04-04T22:10:00.000-07:00

Database corruption is unfortunate for any database administrator. Damage in database mainly occurs due to metadata structure corruption, improper shutdown of system or server, or malicious software like virus. Although most logical corruption in SQL Server database can be surmounted using DBCC CHECKDB repair command, there are some situations wherein the command fails to repair. These situations occur when the database is severely corrupted and beyond the repair limits of DBCC CHECKDB. In such cases, it is advisable to restore database from an updated backup. But if the backup is unavailable or deficient, then the administrator needs to search for a third-party SQL Database Recovery application.

To illustrate above problem, consider a database administrator receives a database corruption error message while trying to access database. However, on trying to repair database using DBCC CHECKDB command, another error message is encountered:

“Could not repair this error.”

This is severity level 10 error message. As the error message states, the in-built repair command is unable to repair the database. After the above error message flashes, the data saved in the database becomes inaccessible. In addition, the same error message is encountered on every attempt to repair database, using different repair parameters.

Cause:

The repair command fails to repair the database because:

There is severe damage in PFS (Page Free Space), GAM (Global Allocation Map), or SGAM (Shared Global Allocation Page) pages.
Database corruption requires rebuilding of clustered indexes for all or few system tables.

Resolution:

To surmount the above error message and to access the database records, you will need to:

Restore the database from an updated backup.
In case of no backup availability, you need to opt for a commercial SQL Database Repair product.

Such SQL Recovery applications use advanced scanning and repairing techniques to repair any logically corrupted database. These tools can be installed from the Internet and do not require any technical knowledge to perform repair process. Such repair utilities do not make even a single change in the original database.

SQL Recovery comprehensively repairs and restores all SQL Server databases, irrespective of their cause of damage. The SQL Repair utility supports repair of MS SQL Server 2008, 20005, and 2000 databases. It is compatible with Windows 7, Vista, 2008, XP, 2003, and 2000 operating systems.

Tips To Resolve “offset 0xADDRESS is invalid” Error Message

2010-03-31T02:25:00.001-07:00

A severity level 16 table error message occurs, while trying to open a MS SQL table, when the database table gets badly corrupted. Few causes of severe corruption of a SQL table are improper system/server shutdown, virus infection, metadata structure damage, and human mistakes. The database table records become inaccessible when a database user encounters error message with so much severity. An easy way to access table records post the above error message, is by restoring data from an updated backup. However, if the backup file is unobtainable or deficient, then a user can use DBCC CHECKDB command to repair the table. But, running this command might lead to loss of records saved in the table. To prevent any loss of records, a database user needs to repair his/her table using a third-party SQL Recovery application.

The above situation can be explained better by following severity level 16 error message:

“Table error: Object ID O_ID, index ID I_ID, page P_ID. Test (TEST) failed. Slot S_ID, offset 0xADDRESS is invalid.”

This error message flashes on your screen when you try to open a MS SQL Server table. After the error message pops up, the table can not be opened. The records saved in the table become inaccessible.

Cause:

The above error message appears when table is corrupt, either through logical crash or physical damage.

Resolution:

To get rid of the above severity level 16 error message, you need to identify the cause of corruption. To do so follow the below mentioned steps:

You should review the Server, system, and application logs. In case you find any entry related to a particular damaged hardware component, you should change that system component.

To analyze logical failure, you can run DBCC CHECKDB command without a repair clause. This helps you to identify the exact level of corruption. After doing so, run the same command with an applicable repair clause.

In case logical corruption persists, you should opt for a commercial SQL Database Recovery software. A SQL Repair application repairs logically damaged databases without harming the original database.

SQL Recovery repairs logically corrupt MS SQL Server 2008, 20005, and 2000 databases in a few mouse clicks. The advanced scanning methods used by the software ensure maximum repair of almost all database objects. The read only SQL Repair utility is designed for Windows 7, Vista, 2008, XP, 2003, and 2000.

Insufficient Disk Space During Upgrade May Corrupt SQL Server Database

2010-03-26T05:22:00.000-07:00

You may encounter SQL Server object or database corruption if you fail to provide enough disk space for the database growth while upgrading Microsoft SQL Server database. This situation may damage sysdepends table in model database and the process may stop responding. You do not receive any error message when this process fails and table corruption occurs. After corruption, the database may become inaccessible and you encounter data loss. In order to retrieve inaccessible data from MDF (Master Database File) database of SQL Server, you need to opt for MS SQL Recovery alternatives.

The sysdepends is a SQL Server database table, which provides dependency relationship information between persistent objects of database. The persistent objects can be providers (database objects depend upon them) and/or dependents (they depend upon other database objects).

Root of the problem

This problem occurs if data file is nearly full (only a few pages are free) and file growth on data file is adjusted to 0% (percent). In this case, the upgrade process doesn't have sufficient scape to finish the upgrade of database. In such circumstances, the database is left in partially upgraded and corrupt state. To Recover SQL database in these situations, you need to sort out this behavior.

Solution

To fix the above mentioned problem:

Replace 'model' database. Follow the below mentioned steps to replace it:
Restore a good copy of SQL Server model database to affected server. If you encounter any error regarding 'msdb' database, you can ignore it.
Copy in the model database from new MS SQL Server installation. After copying in a new model database, you may lose the changes that you have made to previous model database.
Restore a model database of the earlier version of SQL Server and increase the size of database. Add new database to SQL Server installation.
Re-run the SQL Server upgrade process.

The above method helps you to fix model database corruption, but can not repair the damaged SQL Server database. To retrieve data from MDF file, SQL Database Recovery is required.

Recovery is best possible with the help of advanced MS SQL Recovery software. These are third-party utilities, which thoroughly scan entire database to extract all inaccessible or damaged data from it.

SQL Recovery is a read-only and easy to use software for absolute recovery of damaged MDF database. The software works well with Microsoft SQL Server 2008, 2005, and 2000. It restores all database objects such as tables, reports, forms, constraints, stored procedures, and triggers.

Improper Configuration Settings in SQL Server May Cause Database Corruption

2010-03-24T21:55:00.000-07:00

Are you unable to start Microsoft SQL Server? Is your MDF (Master Database File) of MS SQL Server is inaccessible? This behavior may occur due to inconsistency or corruption in Microsoft SQL Server database. If the SQL Server application can not be accessed, problem can be due to application crash, which may cause MDF corruption. This behavior of MS SQL Server database leads to critical data loss situations, and needs SQL Server Recovery to get your mission critical data back in working state.

In case of corruption of the SQL Server database or Microsoft SQL Server application itself, the database can not be mounted or accessed successfully. There are numerous reasons, which may lead to SQL Server and SQL Server database corruption, such as virus infection, improper system shutdown, operating system failure, application malfunction, missing or damaged system files, and more.

As a practical example of the above problem, you may come across the below error message when you try to start Microsoft SQL Server 2005:

"Could not start the SQL Server (SQL2005) service on Local Computer

Error 14001: This application has failed to start because the application configuration is incorrect.
Reinstalling the application may fix this problem.”

After occurrence of the above error message, SQL Server application can not be opened. In such situations, the MDF database becomes inaccessible and unmountable. In order to gain access of your valuable data in SQL Server database, you need to find out the cause of this behavior and perform SQL Server Recovery by sorting it out.

Cause

The major reason of this problem is problem in SQL Server configuration. The configuration is either corrupt or incorrect. The same problem may also occur if any of the critical system files of SQL Server is corrupt or missing.

Resolution

In order to sort out this behavior of Microsoft SQL Server and access MDF database, you need to reinstall SQL Server application. In case of database corruption, you need to Recover SQL Server database using third-party applications.

The SQL Database Recovery software are particularly designed to carry out in-depth scan of entire database and extract all the corrupt or inaccessible database objects. They come equipped with simple and rich graphical user interface to provide ease of use. With read-only nature, these tools preserve integrity of your database.

SQL Recovery software repairs and restores damaged MDF database in all possible corruption scenarios. The software works well with Microsoft SQL Server 2008, 2005, and 2000. It restores all database objects such as tables, reports, formats, triggers, stored procedures, and constraints.

SQL Server Database Corruption If You Run a Query with Parallel Execution Plan

2010-03-23T03:30:00.000-07:00

You may come across Access Violation if you run an SQL query, which uses parallel execution plan in Microsoft SQL Server 2008. Access violation is an error condition, which may occur while performing general operations on the SQL database. It may occur due to application malfunction, software bug, or database corruption. It renders your database inaccessible and may cause data loss, if you don't have a complete backup to restore data from. To overcome such issues, SQL Database Recovery is required.

As an example of Access Violation in Microsoft SQL Server 2008, consider the below scenario:

In MS SQL Server 2008, you're running a query that includes all the below mentioned clauses:
Inner join
Union all
Group by
The database query is using parallel execution plan.
You execute the query.

In the above scenario, you may face access violation. And, you receive the following error message:

“Location: xbmp.cpp:2038
Expression: 0 != pxteBitmap
Msg 3624, Level 20, State 1, Line 2
A system assertion check has failed. Check the SQL Server error log for details. Typically, an assertion failure is caused by a software bug or data corruption. To check for database corruption, consider running DBCC CHECKDB. If you agreed to send dumps to Microsoft during setup, a mini dump will be sent to Microsoft. An update might be available from Microsoft in the latest Service Pack or in a QFE from Technical Support.
Msg 0, Level 20, State 0, Line 0
A severe error occurred on the current command. The results, if any, should be discarded.”

Furthermore, the mini-dump file is returned under the log folder of MS SQL Server 2008.

Cause

As sated in the above error message, this problem may have occurred due to either database corruption or a software bug. After corruption, SQL Server can not read the database and this behavior occurs.

Resolution

Run DBCC CHECKDB utility to try fixing database corruption. If the database is severely corrupted, it may not work. In such cases, third-party SQL Server Recovery applications are worth using.

The MS SQL Recovery applications are particularly designed to thoroughly scan whole SQL Server database and extract all damaged and inaccessible objects from it. They allow you to perform SQL Recovery on your own as they have simple and rich graphical user interface.

SQL Recovery software safely and successfully repairs damaged SQL Server database in all cases of corruption. It works well with Microsoft SQL Server 2008, 2005, and 2000. The software restores all database objects such as tables, reports, forms, macros, and more.

SQL Database Corruption If You Shrink The Database When It Is Use

2010-03-20T02:49:00.000-07:00

In MS SQL Server, you can shrink tempdb database to a size smaller than last configuration of the database. There are various methods that you can use to remove the unused pages of the database and reduce its size. You can also shrink the individual files in SQL Server database. In some methods, you must not do any operation on the database while shrinking. You should not shrink the database when it is in use. It may damage the database and cause serious data loss situations. If you mistakenly do it, SQL Database Recovery becomes essential.

In Microsoft SQL Server, you should use the SQL Server Management Studio in place of Enterprise Manager and Query Analyzer to carry out the tempdb shrink operations. SQL Server Management Studio doesn't show proper size of the tempdb files after shrink operation. The value of “Currently allocated space” is taken from the sys.master_files DMV and it isn't updated after you shrink the database. You can get the exact size of tempdb database using the below mentioned statement after shrinking the database:

“use tempdb

select (size*8) as FileSizeKB from sys.database_files”

What happens if you shrink the tempdb database using DBCC SHRINKFILE or DBCC SHRINKDATABASE commands while the database is in use:

If you try to shrink the database through DBCC SHRINKFILE or DBCC SHRINKDATABASE that is in use by another process, you may come across various database consistency errors, similar to the below errors:

“Server: Msg 2501, Level 16, State 1, Line 1 Could not find table named '1525580473'. Check sysobjects.”

Or

“Server: Msg 8909, Level 16, State 1, Line 0 Table Corrupt: Object ID 1, index ID 0, page ID %S_PGID. The PageId in the page header = %S_PGID.”

After the above error message, shrink operation fails.

Error 8909 indicates corruption in tempdb database. You may also encounter this problem if the SQL Server database is damaged. In order to sort out this problem and fix consistency errors, use Eseutil utility.

If the above method does not work, Repair SQL database using commercial applications. MS SQL Recovery software methodically scan the damaged database and restore all of its data.

The SQL Repair applications do not demand sound technical skills to restore the database due to simple and rich graphical user interface. They have read-only conduct and thus preserve integrity of your valuable data.

SQL Recovery software works in all cases of MS SQL Server database corruption scenarios. It is designed for Microsoft SQL Server 2008, 2005, and 2000. The software restores all MDF items such as tables, reports, forms, queries, triggers, constraints, and stored procedures.

Index Corruption May Damaged Microsoft SQL Server Database

2010-03-18T21:45:00.001-07:00

Are you getting index corruption errors in SQL Server 2000 database while running DBCC CHECKDB statement? Index is a data structure in SQL Server database, which improves the performance of database operations. SQL Server uses indexes for accessing data from the MDF (Master Database File) database. In case of corruption, SQL Server may not locate and access the data or even the database itself may get damaged. It leads to critical data loss situations and needs SQL Database Recovery to be fixed.

In a practical scenario, you may come across the below error messages when you run DBCC CHECKDB statement on a MDF database that is upgraded to MS SQL Server 2000 from an earlier version:

Server: Msg 8951, Level 16, State 1, Line 1
Table error: Table '' (ID ). Missing or invalid key in index '' (ID ) for the row:
Server: Msg 8955, Level 16, State 1, Line 1 Data row (1:133:42) identified by (RID = (1:133:42) ) has index values ( = 0).
Server: Msg 8952, Level 16, State 1,
Line 1 Table error: Database '', index '.' (ID ) (index ID ). Extra or invalid key for the keys:
Server: Msg 8956, Level 16, State 1, Line 1
Index row (1:137:0) with values ( = 0) points to the data row identified by (RID = (1:133:42)).

After the above errors, you cannot check the integrity and consistency of the database and it remains in inconsistent state. In order to gain access of your database in such cases, you need to find out the cause of this behavior and perform SQL Server Recovery by fixing it.

Root of the issue

In earlier versions of SQL Server, like SQL Server 7.0, if sysindexes.status value is set to 0 for nonclustered index in table, nonclustered index also enables insertion of the NULL values. When you run DBCC CHECKDB statement on database of SQL Server 7.0, you do not encounter such problem. After upgrading to SQL Server 2000, DBCC CHECKDB statement displays the above error messages because the NULL values isn't allowed when sysindexes.status value isn't 2097152.

This problem may also occur if the MDF file is damaged due to virus infection, improper system shutdown, or other similar reasons.

To sort out such issues, MS SQL Recovery is essential. It is possible through powerful and advanced third party SQL Recovery software. They enable safe, easy, and quick recovery of your valuable data.

SQL Recovery restores all MDF file objects such as tables, reports, forms, triggers, stored procedures, and constraints. The software works well with MS SQL Server 2008, 2005, and 2000.

DBCC CHECKDB Reports Corruption in Microsoft SQL Server

2010-03-16T23:24:00.001-07:00

Is DBCC CHECKDB statement giving you consistency errors while checking the integrity and consistency of SQL Server database? This behavior occurs due to corruption to MDF (Master Database File) of Microsoft SQL Server and renders all your valuable data inaccessible. It leads to critical data loss situations. In order to get your mission-critical data back in such cases, SQL Database Recovery through reliable applications, is required.

The consistency errors are reported by DBCC CHECKDB tool, if the below situations true:

SQL Server loads the data in a column, which has sql_variant data type.
Data is originated in another column, having sql_variant data type. Additionally data is placed on-the-wire by MS SQL Server.
Numeric values are stored in sql_variant column.

Following are a few instances of SQL statements, which can result into this behavior:

The INSERT..SELECT statement, which specifies remote server in FROM clause of SELECT statement.
A BULK INSERT or a bcp statement from the file, which was created by SELECT statement from the SQL Server.
The database load through Data Transformation Services.

At the same time, you may also receive error messages similar to the following ones:

Server: Msg 2537, Level 16, State 43, Line 1 Table error: Object ID 587149137, index ID 0, page (1:1325), row 0. Record check (innerLength <= innerColInfo.CbMaxLen () && innerPCol != NULL) failed. Values are 17 and 5.
Server: Msg 2537, Level 16, State 1, Line 1 Table error: Object ID 587149137, index ID 0, page (1:1325), row 0. Record check (Valid SqlVariant) failed. Values are 1 and 0.
DBCC results for 'myvar2'. There are 1 rows in 1 pages for object 'myvar2'. CHECKTABLE found 0 allocation errors and 2 consistency errors in table 'myvar2' (object ID 587149137). repair_allow_data_loss is the minimum repair level for the errors found by DBCC CHECKTABLE (pubs.dbo.myvar2 ).

Microsoft offers a hotfix to sort out this problem, which can be downloaded from Microsoft's website. To repair and restore the damaged Microsoft SQL Server database, third-party SQL Server Recovery software can help you.

The MS SQL Recovery applications employ advanced scanning algorithms to thoroughly scan entire database and restore it to working state. They come equipped with simple and self-descriptive graphical user interface and allow you to carry out SQL Recovery on your own.

SQL Recovery is the most efficient utility that ensures absolute recovery in all MDF corruption scenarios. It works well with Microsoft SQL Server 2008, 2005, and 2000. The software restores all database objects such as tables, reports, forms, stored procedures, triggers, and constraints.

Causes of Error 823 in SQL Server and How to Fix it

2010-03-14T22:47:00.001-07:00

Do you encounter Input/Output (I/O) errors while accessing a MS SQL Server database? Are you unable to run queries on or access data from MDF (Master Database File)? This behavior indicates system or hardware problems with SQL Server that corrupt the database and renders it inaccessible. It leads to critical data loss situations. In order to extract data from Microsoft SQL Server in such situations, you need to opt for SQL Recovery solutions.

Hardware and system problems in SQL Server are generally indicated by an error message, similar to the following one:

“Error 823
I/O error detected during at offset in file ''”

You come across this error message when SQL Server attempts to read data from and write data to the database files. Format of this error message can be different, depending upon the version of SQL Server.

Cause

You come across this error message, if any of the below conditions are true:
Operating system error.
I/O logical check failure.
MS SQL Server database corruption.

If any of the above situations occur, it becomes essential to perform SQL Server Recovery by resolving it, to retrieve inaccessible data.

Solution

Try out the below things to fix up this issue, as per the cause of the the problem:

Operating system error: The read Windows API (Application Programing Interface) call or the write API call is unsuccessful and MS SQL Server experiences operating system errors, which is related to Windows API call. Run operating system integrity checking tools. Following is the example of operating system error:

“2003-07-28 09:01:27.38 spid75 Error: 823, Severity: 24,
State: 2
2003-07-28 09:01:27.38 spid75 I/O error 1117 (The request could not be performed because of an I/O device error.) detected during read at offset 0x0000002d460000 in file 'e:\program files\Microsoft SQL Server\mssql\data\mydb.MDF'”
I/O check failure: If specified logical data checks are unsuccessful, you may encounter this problem. Run DBCC CHECKDB to solve this issue.
Database corruption: Restore the database from recent backup. If the backed is unusable, Recover SQL database through third-party applications.

The SQL Database Recovery software are powerful enough to handle most of the database corruption issues. The applications use high-end scanning methods to ensure absolute recovery. They are incorporated with rich graphical user interface to provide quick and easy recovery.

SQL Recovery is the most advanced and powerful utility that is able to effectively handle all database corruption scenarios. The software works well with Microsoft SQL Server 2008, 2005, and 2000.

Database Corruption After Running Alter Table Command on SQL Server Table

2010-03-09T21:57:00.000-08:00

Are you getting incorrect results when you run “alter table” T-SQL (Transact-SQL) command for changing a column to null that is not null? The problem is caused if table column is the clustered index is in MS SQL Server 2000. This behavior may corrupt the MS SQL Server database (MDF) and make all your valuable data inaccessible. In such circumstances, you need to opt for SQL Database Recovery solutions, if an updated backup is not in place.

Along with the incorrect results of alter table command, you may also come across the below database corruption symptoms:

You get the records, which have null columns. But, you want only the rows, which have columns that aren't null.
The MDF file is marked as suspect. Furthermore, the SQL Server database becomes unavailable. You see some runtime errors in the error log of SQL Server.
If you check the logical and physical integrity of the database through DBCC CHECKDB command, it gives you the below corruption errors:

“Server: Msg 8934, Level 16, State 2, Line 1
Table error: Object ID 1977058079, index ID 1. The high key value on page (1:77) (level 0) is not less than the low key value in the parent (0:1), slot 0 of the next page (1:82).
Server: Msg 8933, Level 16, State 1, Line 1
Table error: Object ID 1977058079, index ID 1. The low key value on page (1:78) (level 0) is not >= the key value in the parent (1:75) slot 2.”

This behavior renders your database inaccessible. In order to gain access of your valuable data, you need to find out the cause of this problem and perform SQL Recovery by sorting it out.

Cause

This issue occurs if underwritten conditions are true:

MS SQL Server can't synchronize column status between sysindexes system table and syscolumns system tables.
Column is part of clustered index key, which may be null.

Solution

You can fix it by running dbcc dbreindex command by using repair_rebuild option. However, this method can not Recover SQL database.

In such situations, MS SQL Recovery software come for your help. These are powerful third-party applications, which methodically scan entire database to retrieve inaccessible data from it. They are totally safe and easy to use.

SQL Recovery is the most advanced solution to handle all types of SQL Server database corruption issues. It recovers all database objects such as tables, reports, formats, stored procedures, constraints, triggers, and more. The software is designed for Microsoft SQL Server 2008, 2005, and 2000.

MS SQL Server Database Corruption May Cause Access Violation

2010-03-05T22:27:00.000-08:00

Are you facing Access Violation error in MS SQL Server? Are you unable to access the database and its objects? Access Violation is a situation where application can not access the data because the data is either damaged or the application does not own the data. In both the cases, your database remains inaccessible and unusable. This behavior may lead to significant data loss and needs MS SQL Recovery to be fixed.

In a practical scenario, consider:
In MS SQL Server 2008, a query contains the following clauses:
Union all
Group by
Inner join

The database query uses parallel execution plan.
You execute the query.

In this case, you may come across an Access Violation. Additionally, you may encounter the below error message:

“Location: xbmp.cpp:2038
Expression: 0 != pxteBitmap
Msg 3624, Level 20, State 1, Line 2

A system assertion check has failed. Check the SQL Server error log for details. Typically, an assertion failure is caused by a software bug or data corruption. To check for database corruption, consider running DBCC CHECKDB. If you agreed to send dumps to Microsoft during setup, a mini dump will be sent to Microsoft. An update might be available from Microsoft in the latest Service Pack or in a QFE from Technical Support.

Msg 0, Level 20, State 0, Line 0

A severe error occurred on the current command. The results, if any, should be discarded.”

After the above error, database can not be accessed. In order to gain access of your SQL Server database, you need to carry out SQL Server Recovery by fixing this behavior.

Cause

As stated in the error message, you may have encountered such situations due to application malfunction or database corruption. Database corruption may occur after virus infection, unexpected system shutdown, operating system malfunction, and other similar situations.

Resolution

Consider running DBCC CHECKDB command to get your database repaired. It is an inbuilt utility in SQL Server that checks integrity and consistency issues of MDF (Master Database File).

However, if this tool can not fix the problem, third-party SQL Database Recovery software are always there for your help. These are advanced tools, which methodically scan entire database and ensure absolute SQL Recovery in most of the database corruption situations.

SQL Recovery is the most efficient tool to ensure absolute recovery of your damaged database. The software works well with Microsoft SQL Server 2008, 2005, and 2000. It restores all database objects such as tables, reports, forms, queries, stored procedures, triggers, and constraints.

Tips to resolve “Extent E_ID in database ID DB_ID...”

2010-03-04T22:07:00.000-08:00

GAM (Global Allocation Map), SGAM (Shared Global Allocation Map), and IAM (Index Allocation Map) pages are three very important building blocks of SQL Server metadata structure. A GAM page contains one bit for each extent, where each bit states if the extent is already allocated or is available for allocation. Similarly, SGAM page too consists of one bit for every extent, which states whether the extent is mixed or dedicated, and contains one or more allocated pages. An IAM page again has one bit per dedicated extent, which is assigned to the index for which the IAM is a part. A systematic combination of these bits assures that the database is perfectly fine and is in usable state. However, the combination becomes damaged in case the database gets logically or physically corrupted. To overcome such situations, the user needs to opt for SQL Database Recovery solutions.

Below is the error message explaining the above scenario:

“Extent E_ID in database ID DB_ID is marked allocated in the GAM, but no SGAM or IAM has allocated it.”

After the above error message pops up, the database records become inaccessible. The above error message occurs due to following reasons:

When the extent is dedicated and also mixed.
When the extent is dedicated and also unallocated.
When the extent is mixed and also unallocated.
When the extent is dedicated, mixed, and also unallocated.

Resolution:

To resolve the above error message and to access database records, user will need to perform below actions:

Check for physical corruption of database by viewing application logs, SQL Server log, and system logs. To fix any hardware-related issue, the user will need to change the damaged system component.
Restore the data from an updated backup.

Check for logical corruption in database by executing DBCC CHECKDB command. This will enable the user to determine the exact extent of corruption. To fix the logical corruption, the user will need to run the same command with a repair clause. If the logical corruption persists, then s/he needs to take help of advanced SQL Database Repair application. A SQL Recovery tool employs effective repairing techniques to resolve all logical corrupted databases.

SQL Recovery repairs and restores MS SQL Server 2008, 20005, and 2000 databases, post any logical corruption scenario. The read only SQL Repair utility is safe-to-use as it does not modify the original database while repairing. It supports Windows 7, Vista, 2008, XP, 2003, and 2000 operating systems.

How to Resolve “The text, ntext, or image node...” Error

2010-03-03T21:11:00.000-08:00

The B-tree metadata structure of a SQL Server database saves the table records in various nodes, which are linked to each other in a hierarchical order. These nodes are primarily of three types – root node, branch node, and leaf node. The root node includes the value of branch nodes, which further contains values of leaf nodes. However, there might be certain situations where the child node does not match with the parent node. This situation mainly occurs when your SQL Server database gets corrupted/damaged. In such cases, you receive an error message while accessing the records saved in the SQL Server table. To access the table records after SQL database damage, restore the data from an updated backup. However, if no backup is available or backup does not fulfill your requirement, then you need to repair the table using a SQL Database Recovery software.

The above scenario is explained using the below error message:

“Table error: Object ID O_ID. The text, ntext, or image node at page P_ID1, slot S_ID1, text ID TEXT_ID does not match its reference from page P_ID2, slot S_ID2.”

The error message appears when there the child node does not match its parent node. This occurs when:

The timestamp of the parent node is different from the timestamp of the child node.
The child node consists of text data, which is greater than the size of parent node.

The above scenarios primarily occur when your SQL Server database gets logically or physically damaged. To overcome the above error message and to access the table records, you need to repair the database. To do so, below are the two ways:

A physically damaged database requires replacement of damaged system component.
A logically corrupted database can be repaired using an inbuilt repair command – DBCC CHECKDB. The statement should be executed with a correct repair clause. In case logical corruption persists after running the above repair command, then you need to search for an effective MS SQL Recovery application that can repair your database. To find a powerful SQL Database Repair tool, search the Internet.

SQL Recovery is one powerful tool that successfully repairs logically corrupted database created in SQL Server 2008, 20005, and 2000. The repaired database is in re-usable state and can be stored at required destination. The SQL Database Repair application supports Windows 7, Vista, 2008, XP, 2003, and 2000.

Storing SQL Server Database on Network Server May Cause Corruption

2010-03-02T23:13:00.000-08:00

Microsoft usually urges that you should use a SAN (Storage Area Network) or locally attached hard drive to store MS SQL Server database (MDF) files as this configuration improves SQL Server reliability and performance. Use of network database (stored on network server or NAS [Network Attached Server]) is disabled by default in Microsoft SQL Server. In order to ensure complete data safety and to prevent need of SQL Database Recovery, you should not use SQL Server database on networked server.

Though, it is not recommended, but it is possible to configure MS SQL Server for storing the database on a NAS storage server or networked server. Data storage servers, that are employed to store MDF database, must meet the SQL Server needs for 'write-through guarantees' and 'data write ordering'.

If you try to create SQL Server database file on UNC or mapped network location results into any of the below error message:

5105 "Device Activation Error"

Or

5110 "File 'file_name' is on a network device not supported for database files."

The above behavior is quite expected. The trace flag 1807 let you to bypass the check process and enables you to configure MS SQL Server with the networked database files. Microsoft SQL Server and various other relational database management systems use the transaction log and associated recovery logic, that ensure database integrity and consistency in case of system failure or improper system shutdown.

These SQL Server Recovery protocols bank on the capability to write instantly on the hard drive media so that if any operating system I/O (Input/Output) write call returns to database manage, recovery system is assured that write operation is really complete or the completion of write process can be ensured. Any type of failure by any hardware or software components of this protocol may result in complete or partial data loss due to corruption of MDF file.

In such critical circumstances, you need to restore the damaged database from the most recent backup. However, if the backup is either not available or not updated, third-party MS SQL Recovery software is the only way to go.

The MS SQL Recovery applications are powerful enough to carry out in-depth scan of entire SQL Server database and extract all inaccessible database objects. With the read-only and simple graphical user interface, they are completely safe and easy to use.

SQL Recovery is the most prominent tool that enables absolute recovery in all cases of MDF corruption. It restores all database objects such as tables, reports, forms, modules, queries, constraints, stored procedures, and triggers. The software is compatible with MS SQL Server 2008, 2005, and 2000.

Fixing “Multiple IAM pages for object....” Error Message

2010-03-01T22:15:00.000-08:00

MS SQL Server database data files are divided into numerous GAM (Global Allocation Map) intervals. Each GAM interval consists of at least 4GB space or 64,000 extents. The page interval allocates one or more pages to an index that contains an IAM (Index Allocation Map) page for that GAM interval. However, the problem occurs when the index contains more than one IAM page for a GAM interval. The above situation primarily occurs when the SQL Server database gets corrupted or damaged. To overcome such database corruption scenarios, an easy way followed by most of the database users is restoration from an updated backup. However, in case of unavailability of a valid backup, you need to use advanced MS SQL Recovery application.

Consider a practical case, where you attempt to access the records saved in one of your tables. Instead of viewing the table records, you receive the below error message:

“Table error: Multiple IAM pages for object ID O_ID, index ID I_ID contain allocations for the same interval. IAM pages P_ID1 and P_ID2.”

The same error message pops up every time you attempt to access the database table records. Additionally, the records saved in the database table become inaccessible after the above error message pops up.

Cause:

The reason for the occurrence of the above error message is that there are two IAM pages (P_ID1 and P_ID2) that cover the same GAM interval. This occurs either due to physical or logical corruption of the database.

Resolution:

To resolve the above error message and to access the database table records, you need to repair the database using below methods:
Change the damaged/corrupt system component to isolate the physical damage reasons.
Run DBCC CHECKDB command (with repair clause) to isolate all logical corruption scenarios.
If the problem persists, then you need to repair the database using an advanced SQL Database Recovery software. A SQL Repair application repairs corrupt database in all cases of logical corruption.

Stellar Phoenix SQL Recovery is a trust-worthy solution for resolving all sorts of corruptions in SQL database. The software brings the database in a re-usable state in three simple clicks. Compatible with SQL Server 2008, 2005, and 2000, the SQL Repair tool saves the repaired database at required location. It is designed for Windows 7, Vista, 2008, XP, 2003, and 2000.

Fixing “FirstIAM field in sysindexes is P_ID. FirstIAM for...” Error

2010-02-24T21:30:00.000-08:00

A FirstIAM field in MS SQL Server database is the destination of first IAM (Index Allocation Map) page for the index. An IAM page acts like an allocation structure which SQL Server uses to track database objects. The FirstIAM page consists of a value that changes when dummy indexes do not contain the exact storage allocated to them. This primarily occurs when your SQL Server database gets corrupted due to logical or physical reasons. Furthermore, you also receive an error message after the value of FirstIAM page changes. This error message makes the data saved in the SQL database components inaccessible. To overcome the error message in such cases, follow the straight forward approach of restoring the data from an updated backup. However, if the database backup is inaccessible or corrupt/damaged, then use an advanced SQL Recovery application.

To thoroughly explain the above case, below is the error message with its detailed description:

“Object ID O_ID, index ID I_ID: FirstIAM field in sysindexes is P_ID. FirstIAM for statistics only and dummy index entries should be (0:0).”

The above error message appears when the dummy index(es) contain incorrect storage. As a result, the value for FirstIAM page should be 'zero'. However, in this case, the value for FirstIAM page is not 'zero'. After the above error message pops up, the SQL Server database records become inaccessible.

Resolution:

The resolution for the above error message can only be achieved by repairing the database. To do so, you will need to follow the below steps:

If the database is damaged due to any physical damage of a system component, then you will need to change the damaged component with a new component.
If the SQL Server database is logically corrupted, then you will need to execute DBCC CHECKDB command with a suitable repair clause. In most cases, the database is repaired after you run the above command. However, if the command does not repairs your corrupt database, then you will need to use advanced SQL Database Recovery application. The SQL Repair tools use powerful repairing algorithms to repair any logically corrupted database.

SQL Recovery repairs logically corrupt databases and restores them on your desired destination. In addition, the SQL Repair software does not makes even a single change in the original database records. It is compatible with SQL Server 2008, 20005, and 2000 and designed for Windows 7, Vista, 2008, XP, 2003, 2000.

Table Index Corruption May Cause SQL Server Database Corruption

2010-02-23T20:27:00.000-08:00

Are you facing error 644 or 8646 while updating or deleting database table, which contains Unicode column with Latin1_General_BIN collation? Are you unable to access your SQL Server database? Database inaccessibility leads to critical situations of data loss and you need to restore the database from most recent backup of your database. However, if the backup is not available, you need to opt for SQL Recovery solutions to get your valuable data recovered.

In a practical scenario, you may encounter the following error in SQL Server error log while updating, deleting, or opening a database table:

“Error: 644, Severity: 21, State: 5
Could not find the index entry for RID '1613b1000000100' in index page (1:189), index ID 7, database 'TestDB'..
Error: 8646, Severity: 21, State: 1
The index entry for row ID was not found in index ID 7, of table 2009058193, in database 'test644'.”

At this point, if you run the DBCC CHECKDB statement to check the integrity and consistency of your SQL Server database, it does not report any error related to database or table index corruption discussed here. The DBCC CHECKDB tool may report you the below error message when you apply it on the problem database:

“Server: Msg 2511, Level 16, State 1, Line 1
Table error: Object ID 2009058193, Index ID 7. Keys out of order on page (1:189), slots 184 and 185.”

The above example of the error message particularly occur on the non-clustered index of MS SQL Server. But, the problem discussed here also occurs with the clustered indexes. Eventually, this behavior renders your precious data inaccessible. In order to get your database repaired and restored at this point, you must identify the cause of this problem and perform SQL Database Recovery by sorting it out.

Resolution

If you encounter the above error message after running DBCC CHECKDB tool on MDF (Master Database File), you need to rebuild indexes of the table that are indicated in error message.

On the other hand, damaged SQL Server database requires MS SQL Recovery to be handled. Recovery is best possible with the help of powerful and advanced third-party applications, known as SQL Database Recovery software.

How to Fix Master Database Corruption in MS SQL Server

2010-02-17T21:17:00.000-08:00

In Microsoft SQL Server, all the system-level data/information are stored in a Master database. It includes the instance-wide meta data like logon accounts, linked servers, system configuration settings, and endpoints. Furthermore, master database records the creation of other database and location of the database files and initialization information for MS SQL Server. Thus, Microsoft SQL Server can't start if master database is missing, damaged, or unavailable. Corruption of the master database leads to critical data loss situations and requires SQL Recovery.

Microsoft SQL Server facilitate checking the integrity, both logical and physical, of all objects in specified database through DBCC CHECKDB. It includes three modules- DBCC CHECKALLOC, DBCC CHECKTABLE, and DBCC CHECKCATALOG, which are used to perform specific operations. If you run DBCC CHECKDB on any database, you need not run any of its modules on the affected SQL Server database. It also validates contents of indexed view, link-level consistency among file system files/directories and table meta data, and Service Broker data in SQL database.

However, the DBCC CHECKDB can not handle database corruption in all cases and thus your master database may remain inaccessible in those cases. The problem generally occurs in case of severe corruption to the database. In a practical scenario, you may come across the below error message when you run DBCC CHECKTABLE module on a corrupt master database:

“Server: Msg 8952, Level 16, State 1, Line 1
Table error: Database 'master', index 'syscolumns.ncsyscolumns' (ID 3) (index ID 2). Extra or invalid key for the keys:
Server: Msg 8956, Level 16, State 1, Line 1
Index row (1:425:11) with values (id = 1794105432 and name = 'COLUMN_NAME' and number = 0 and id = 1794105432 and colid = 4 and number = 0)
points to the data row identified by ().
CHECKTABLE found 0 allocation errors and 1 consistency errors in table 'syscolumns' (object ID 3).
repair_fast is the minimum repair level for the errors found by DBCC CHECKTABLE (master.dbo.syscolumns ).”

In such situations, you need to use third-party SQL Database Recovery application to get your database repaired and restored. The MS SQL Recovery applications come equipped with self-descriptive and rich graphical user interface to provide easy and quick SQL Server Recovery. The applications have read-only conduct to provide safe recovery.

Stellar Phoenix MSSQL Database Recovery is a powerful application to restore tables, defaults, triggers, stored procedures, rules, and views from damaged MS SQL Server database. The software works well with all database, created through MS SQL Server 2008, 2005, and 2000.

File Header and Boot Page corrupted in MS SQL Server Database

2010-02-16T20:24:00.000-08:00

Just like any other database, MS SQL Server database contains a file header page and boot page. While the file header page (8KB) consists of metadata information about the database, the boot page contains critical information about the database itself. Corruption in any of the above pages primarily results in an error message that result in unmounting of the SQL database. This further results in the inaccessibility of SQL database records, used for various personal and professional uses. In such cases, an ideal way to resolve the above error message is by restoring data from an updated backup. But with inaccessibility of database backup, the only option to access your records is by using an advanced SQL Recovery application.

Consider a practical case, where either of the below error messages pops up when you attempt to access your SQL Server database:

“Msg 5172, Level 16, State 15, Line 1
The header for file 'C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\FileHeaderTest.mdf' is not a valid database file header. The PageAudit property is incorrect.”
Or
“Msg 913, Level 16, State 4, Line 1
Could not find database ID 19. Database may not be activated yet or may be in transition. Reissue the query once the database is available. If you do not think this error is due to a database that is transitioning its state and this error continues to occur, contact your primary support provider. Please have available for review the Microsoft SQL Server error log and any additional information relevant to the circumstances when the error occurred.”

The first error message is caused due to corruption of file header page and the second is a result of boot page corruption. The database records become inaccessible after any of the above error message pops up.

Cause:
Corruption in boot page or file header is due to improper system shutdown, application malfunction, etc. In both the above cases of corruption, repair is not possible by running DBCC CHECKDB command.

Resolution:

To resolve the above error messages and to systematically access the database records, you need to use an efficient third-party SQL Database Recovery application. A SQL Repair tool employs high-end scanning procedures to repair corrupt SQL database and restore it at required destination.

SQL Recovery is a powerful, yet easy to use SQL Repair application that allows even a non-technical user to perform database repair. The read only software is competent enough to repair database built with MS SQL Server 2008, 2005, and 2000. It supports Windows 7, Vista, 2008, XP, 2003, and 2000.

Resolving “Extent E_ID in database” Error Message

2010-02-10T21:56:00.000-08:00

The records saved in a SQL Server database table is divided into various pages, such as GAM (Global Allocation Map) , SGAM (Secondary Global Allocation Map), and IAM (Index Allocation Map). A GAM page comprises of one bit per extent for all the mapped extents in a file interval. An SGAM page is exactly similar to GAM page, the only difference being that every set bit is equal to an extent, in which these pages are individually assigned to IAM pages. An IAM page consists of one bit per dedicated extent. The values saved in the Extents can be get corrupted, if there is any logical corruption in the SQL database. In such scenarios, the database records saved in the tables become inaccessible. Furthermore, you also receive an error message while opening the table. In such cases, the database records saved in the table can be accessed by restoring the table from an up-to-date backup. But, in case of backup unavailability, you will need to opt for powerful SQL Database Recovery utility.

Consider a practical situation, where you receive the below error message while opening a SQL table:

“Extent E_ID in database ID DB_ID is allocated in both GAM GAM_P_ID and SGAM SGAM_P_ID.”

The above error message makes the table records inaccessible.

Cause:

The above error message occurs under following circumstances:

Extent is mixed and dedicated.
Extent is unallocated and dedicated.
Extent is unallocated, mixed, and dedicated.
Extent is unallocated and mixed.

Resolution:

The resolution for the above error message (either due to logical or physical corruption) is discussed below:

Table corrupted due to physical damage required changing of physically damaged component. To identify the damaged component, check the SQL Server and operating system logs.
Table corruption, if occurred due to logical crash, requires you to run DBCC CHECKDB statement without the repair clause. This step enable you identify the exact extent of corruption. Then you will need to search for exact repair clause and run with DBCC CHECKDB command. However, if the error message sustains even after running the above command, then you will need to use advanced SQL Recovery utility. Such SQL Repair tools are readily available on the Internet.

SQL Recovery is one of the finest SQL Database Repair application that repairs SQL Server 2008, 20005, and 2000 database tables and other database components. It is designed for Windows 7, Vista, 2008, XP, 2003, and 2000 operating systems.

Fixing “Table error: Cross object linkage...” Error Message

2010-02-09T03:17:00.000-08:00

Pages in metadata structure of MS SQL Server database are either linked in a B-tree or heap tree format. These pages contain the records of different database components. In such situations, these pages instead of pointing the required pages, start pointing to a wrong page. The database records become inaccessible in case the SQL database gets corrupted or damaged. To access the records saved in the database components, an easy way is to restore the database objects from an updated backup. But, if in case the backup is not available, or backup file is not created, then you will need to repair the SQL database to access all its records. To do so, you will need to use advanced third-party SQL Recovery utility.

To briefly explain the above database corruption scenario, below is the error message that pops up when a SQL database table gets corrupted:

“Table error: Cross object linkage: Parent page P_ID1, slot S_ID1 in object ID O_ID1, index ID I_ID1, and page P_ID2, slot S_ID2 in object ID O_ID2, index ID I_ID2, next refer to page P_ID3 but are not in the same object.”

The above error message makes the data saved in the database table inaccessible. In additions, the user can not perform any operations, such as, addition, modifications, or deletion, on the records of that table. It is a severity level 16 error message.

Cause:

The above error message occurs when the page P_ID2 and page P_ID1's child page pointer in a B-tree, point to the page P_ID3 in some other object. This can happen either due to logical or physical corruption of SQL database.

Resolution:
To isolate the above error message and access the database table records, you will need to follow the below steps:
To isolate the error message, if caused due to physical corruption, change the damaged system component with a new component.
For error message caused due to logical damage, use the DBCC CHECKDB command with appropriate repair clause. But, if the problem sustains, then use SQL Database Repair software to repair the database. Such SQL Database Recovery utilities repair the database components by incorporating effective scanning algorithms.

Stellar Phoenix SQL Recovery is a repair utility that provides orderly repair of SQL Server 2008, 20005, and 2000 database components. The repairable components can be previewed and restored at user-specified location. The SQL Repair tool works on Windows 7, Vista, 2008, XP, 2003, and 2000 operating systems.

Tips to resolve “Table error … offset 0xADDRESS is invalid” Error

2010-02-05T20:48:00.000-08:00

A table in MS SQL database can be corrupted due to various reasons. One of the most common being the corruption in metadata structure, caused due to damage of SQL Server damage. Once the table gets corrupted, it fails to display records stored in it. Furthermore, you also receive an “Table Error” message that does not allow you add any new records. An easy way to overcome such hazards is by restoring the table from an updated backup. But, with probabilities of backup file being corrupted, not updated, or inaccessible always exist. In such situations, the database user is left with no option, but to repair the corrupted table. To effectively do so, the user need to search for an advanced SQL Recovery application.

To illustrate the above case, below is a Table error message that appears after your SQL database table gets corrupted:

“Table error: Object ID O_ID, index ID I_ID, page P_ID. Test (TEST) failed. Slot S_ID, offset 0xADDRESS is invalid.”

The consequences of this error message might prove fatal, as it makes all the records inaccessible.

Cause:

The above Table error message pops up after the table gets corrupted due to logical or physical crash.

Resolution:

The resolution for the above Table error message is discussed below:

In case the table is corrupted due to hardware (system component) crash, then the database user needs to check the logs of SQL Server and System. This enables the user to verify the component that is physically damaged. For comprehensive resolution, the user needs to install a new component in place of damaged component.
In case the table is corrupted due to logical crash, then the user needs to run DBCC CHECKDB with a repair clause. In most cases, the above command repairs the database tables. But if in case, the above falls short of repairing the damaged table, then the user needs to look out for an effective SQL Repair application.

A SQL Repair software is a product developed by highly qualified database repair experts. The tool is easily understood without any prior technical knowledge.

SQL Recovery is an absolute answer to all SQL database corruption scenarios. The software repairs all database file components created in SQL Server 2008, 20005, and 2000. Designed for Windows 7, Vista, 2008, XP, 2003, 2000, the SQL Repair utility is totally non-destructive.

Fixing “Table Error ... index ID I_ID B-tree level mismatch...” Error

2010-02-03T23:21:00.000-08:00

Corruption of MS SQL database can result into damage of metadata structure entries, which can further result into inaccessibility of records saved in the SQL database components. In most cases of metadata structure damage, you receive an error message that specifies the exact metadata entry, which is corrupt. To overcome the error message and to access the database components records, an ideal way is to restore it from an updated backup. However, there are thousand of situations, where either the backup gets corrupted or the database administrator forgets to create a backup. In such cases, the only way to access records of a corrupted SQL database component is by repairing it with a powerful third-party MS Recover SQL application.

Consider a practical case, where you receive the below error message while trying to access a SQL database table:

“Table error: Object ID O_ID, index ID I_ID B-tree level mismatch, page P_ID1. Level LEVEL1 does not match level LEVEL2 from parent P_ID2.”

The table error message doe not allows the table to open, resulting into inaccessibility of all its records.

Cause:

The cause for the above table error message is metadata structure damage, due to which the values of the pages (stored in the form of B-tree structure) changes. The changed values corrupt the linking between the parent nodes and the child nodes in a B-tree.

Resolution:

To resolve SQL database corruption, caused due to any reason, follow the below measures:

If the corruption in SQL database is caused due any physical damage of the system component, then you will need to swap that component with a new component.
If the problem persists even after changing the system component, then it is a logical corruption scenario. For such cases, you will need to run DBCC CHECKDB command with a repair clause.

However, if the error message appears even after running the command, then you will need to opt for a effective SQL Repair utility that can repair your database. The demo versions of such MS SQL Recovery tools allows you to preview you repaired SQL database.

Ghost Records in MS SQL Server

2010-01-29T03:34:00.000-08:00

The background process of “Ghost Cleanup” in MS SQL database is primarily used to improve the performance of Delete command. This record count of total number of the ghosted records is stored in the header. However, if the record count in the header does not match with the exact number of ghosted records, then you receive an error message. The cause for the error message is corruption of your SQL database records. In such situations, it is always advisable to restore the data from an updated database backup. But if in case, you have not maintained any backup, or the database backup is corrupt, then you will need to repair the database by using advanced SQL Recovery application.

Consider a practical scenario, where you encounter the below error message while attempting to access your database table:

“Object ID O_ID, index ID I_ID: The ghosted record count (HG_COUNT) in the header does not match the number of ghosted records (G_COUNT) found on page P_ID.”

The same error message appears every time you attempt to access the table records.

Cause:

The root cause for the above error message, as stated in the message, is that the number of ghosted records found on a particular page P_ID is not matching ghosted record count in the header. This mismatch primarily occurs due to SQL database corruption due to logical or physical reasons.

Resolution:

The resolution for the above error message is categorized in two steps:

In case the SQL database corruption has occurred due to any physical damage of a component, then you will need to replace the component with a new one.

In case of logical corruption of SQL database, you will need to repair the database using 'DBCC CHECKDB' command, with an appropriate repair clause.

The repair command ensures repair of corrupt database in almost every situation. However, if the command is unable to repair the database, then you will need to use powerful third-party SQL Database Repair application. Such Recover SQL tools repair the corrupt database by using effective repairing procedures. These tools are downloadable from the Internet.

SQL Recovery scans, repairs, and restores corrupt/damaged SQL Server database after almost all logical corruption scenarios. Supported by SQL Server 2008, 20005, and 2000, the SQL Repair comes in two versions-trial and complete, both downloadable from the Internet. It is designed for Windows 7, Vista, 2008, XP, 2003, 2000.

Fixing “Forwarded row referenced...” Error Message

2010-01-28T03:22:00.000-08:00

Whenever MS SQL Server encounters a problem while mounting your database, it displays an error message. Each error message displayed contains few important details like, message number, severity level of the problem, the problem itself, and sometimes the solution. The main reason for the occurrence of the error message is corruption is SQL Server database. In such cases of SQL database unmountability, the database records become inaccessible. The fundamental way used by most of the database administrators to access the records is by restoring the database from an updated backup. But, if in case these administrators forget to create a backup file or backup itself gets corrupted, then they will need to repair the database. To do so, they need an efficient SQL Recovery application.

Consider a practical case, where the underneath error message pops up while you attempt to mount the database:

“Forwarded row referenced by more than one row. Object ID O_ID, page P_ID1, slot S_ID1 incorrectly points to the forwarded row page P_ID2, slot S_ID2; the forwarded row correctly refers back to page P_ID3, slot S_ID3.”

This is a severity level 16 error message. After the above error message appears, the data saved in the database becomes inaccessible.

Cause:

SQL database corrupted due to metadata structure damage (either due to logical or physical crash). The metadata structure corruption is causing the forwarded row (S_ID2 on page P_ID2) pointed to by an extra forwarding row (S_ID1 on page P_ID1).

Resolution:

The resolution for the above error message is provided in the below points:

To repair the physical damage, change the damaged system component.
To resolve the logical corruption, run the repair command “DBCC CHECKDB”.

If DBCC CHECKDB does not provides satisfactory results and the same error message appears while mounting the database, then you will need to use an efficient third-party SQL Repair application. The MS SQL Repair repairs corrupt/damaged SQL database(s) in minimum turnaround time. With few simple steps, the powerful repairing algorithms repair the database and restore the database on your desired location. Such utilities are non-destructive in nature.

SQL Recovery is a comprehensive solution to repair the SQL Server 2008, 20005, and 2000 databases. Compatible with Windows 7, Vista, 2008, XP, 2003, 2000, the SQL Database Repair software is available in both demo and full versions. The trial version can be downloaded from the Internet to preview the repairable SQL database file.

Fixing “System table mismatch...” Error Message

2010-01-25T03:32:00.000-08:00

In MS SQL Server database, there is are some specific values in the metadata structure that describe each table. These values once changed due to metadata structure corruption can result in inaccessibility of records saved in the table. Few main causes for metadata structure damage are SQL database damage, virus attack, file system damage, and human errors. Once the table is corrupt, an error message pops up on your screen describing the cause for the same. To surpass the error message and to access the database table records, you need to restore the table from an updated backup. However, if in case, the updated falls short to restore the desired data, then you will need to use an third-party MS SQL Repair tool to repair the corrupted table.

Picture a scenario, where the below error message appears when you attempt to access a database table:

“System table mismatch: Table 'O_NAME' object ID O_ID has index id 1 in sysindexes but the status in sysobjects does not have the clustered bit set. The table will be checked as a heap.”

Since the error message pops up while trying to read the table records, the records stored in the table become inaccessible.

Cause:

The above table error message occurs when the metadata structure describing the table gets corrupted.
The error is a “severity level 16” error message.

Resolution:

The resolution for the above error message is provided in the below points:

To resolve the table error, if caused due to physical damage of a system component, you will need to change the damaged system component with a new one.
The above error, if caused due to logical corruption, can be resolved by running DBCC CHECKDB command with correct repair clause. However, if the above error persists even after running the repair command, then you will need to opt for SQL Repair tool for repairing the table.

The MS SQL Recovery tool ensures repairing of tables and other database components. The tool is embedded with interactive user manual, that makes it self-explanatory without any prior technical knowledge.

SQL Recovery is a complete solution to repair corrupt SQL Server database components, including tables. Compatible with SQL Server 2008, 20005, and 2000, the SQL Database Repair software supports Windows 7, Vista, 2008, XP, 2003, 2000 operating systems. The software is downloadable from the Internet.

Tips to resolve “Could not repair this error” Error Message

2010-01-22T03:16:00.001-08:00

There are some error messages that can not be resolved by automatic fixes. These error messages mainly occur when the MS SQL database file gets badly corrupted, resulting into complete damage of its metadata structure. In such cases, the database records stored in the database file become inaccessible. For overcoming the consequences created after such error messages, you will need to use an updated database backup to restore the records. While most of the database administrators ensure that they have an readily backup available at the time of such adversities, there are certain instances where they either forget to create a backup or there backup file gets corrupted. In such situations, the database file can be easily repaired by using advanced MS SQL Repair application.

To illustrate the above case, consider a practical situation, where you receive the below error message while mounting the SQL Server database:

“Could not repair this error”

The above error message not only makes the database unmountable, but also makes its records inaccessible. To add to your difficulties, you receive the same error message (does not specify the exact cause) every time you attempt to access the database.

Cause:

The above error message primarily occurs SQL database corruption because three below reasons:

There are some errors in the PFS (Page Free Space) page.
Unable to rebuild clustered index of critical system tables.
Unable to rebuild corrupted GAM or SGAM pages.

The above error message is a severity level 10 error message and can be caused due to logical or physical crashes.

Resolution:

The error message can be resolved by repairing the database by using a third-party SQL Repair tool. A MS SQL Recovery utility can be downloaded from the Internet and can be used even by a novice user. The database repair software does not overwrite the original content of MDF file, making a risk-free repair application. The to-the-point documentation of the software makes the software easily understandable. Such tools are developed by highly qualified data recovery experts.

SQL database corruption result in “Table Error”

2010-01-20T21:10:00.000-08:00

A corrupted SQL Server database has many shortcomings, one of them being the unmountability of the database. In most cases, the corruption is caused due to these factors – file system damage, virus infection, metadata structure damage, and concurrent modification of same database component. An error message pops up when you attempt to access the database records after the database is corrupted. This error message does not allow you to view the records stored in that database component. To access data in such situations, you will need to restore the database component from an updated backup. But if in case, the backup is unavailable or has not been maintained for that particular component, then you will need to repair the database using an advanced SQL Database Recovery application.

Consider a practical scenario, where you receive the below error message when you attempt to access the records stored in your database table:

“Table error: Object ID O_ID, index ID I_ID, page ID P_ID1. The PageId in the page header = P_ID2.”

The database table error message makes the records stored in the table inaccessible. The same error pops up every time you try to open that particular database table. This is a severity level 16 error message.

Cause:

The above error message appears when DBCC asks for P_ID1 page, but found P_ID2 in the disk header. This can occur due to logical or physical damage of the SQL database.

Resolution:

The solutions for the above error message are discussed below:

For solving the physical damages, you will need to replace the damaged system component with a brand new component.

For solving logical crashes, run DBCC CHECKDB command to identify the exact level of corruption. After complete identification, run the same command with the appropriate repair clause. The result of the repair primarily depends upon the page type. However, if the above command fails to repair the database, then you will need to opt for a powerful SQL Database Repair software.

These SQL Repair tools can be downloaded from the Internet and are easy to understand because of their interactive user-interface. With no modifications on the original database, these tools are absolutely safe to use.

Fixing “Page P_ID in database ID...” Error Message

2010-01-17T20:42:00.000-08:00

A PFS (Page Free Space) page tracks the allocation status for every page and the amount of free space available on the page. The database engine uses the information stored in the PFS pages to allocate new pages. The page stores the information in the form of bytes, including a byte that indicates that the page is a mixed page. An IAM (Index Allocation Map) page, on the other hand is an array that stores all the mixed pages assigned to a particular index. The data stored in the database components becomes inaccessible if the page that is assigned a 'mixed page' byte in PFS page, not the same page does appear in the IAM page's array. This primarily occurs due to SQL database corruption. In such cases, the database becomes unmountable, further resulting into inaccessibility of its records. For complete accessibility of records in such situations, you will need to restore the data from an updated backup. But, if backup is not available, then you will need to use advanced MS SQL Recovery application.

As a practical case, the below error message pops up while attempting to access your SQL database records:

“Page P_ID in database ID DB_ID is allocated in the SGAM SGAM_P_ID and PFS PFS_P_ID, but was not allocated in any IAM. PFS flags 'PFS_FLAGS'.”

The same error message pops up every time you attempt to access the database records. The database records become inaccessible, once the above error message appears.

Cause:

The above error message pops up when the page P_ID in the database is allocated as mixed page byte in PFS page, but the mixed page does as IAM page or in an IAM page's array. This occurs due to corruption of database due to logical or physical crash.

Resolution:

The resolution for the above error message is discussed below:
If the corruption is caused due to physical damage of a system component, replace the system component.
If the error pops up due logical crash scenarios, then you will need to run DBCC CHECKDB command using correct repair clause.

However, if both the resolutions fail to resolve the issue and the error message pops up while mounting the database, then you will need to repair the database using SQL Database Recovery application. Such SQL Repair tools can be easily downloaded from the Internet.

DBCC CHECKDB unable to resolve SQL Database corruption

2010-01-15T20:28:00.001-08:00

The logical and physical integrity of all SQL Server database tables is performed by DBCC CHECKDB command. The command performs and divides its operations in three different phases. The first phase checks the consistency of the allocation structures in disk space, the second phase checks the integrity of all pages and their structures, and the last phase checks the catalog consistency. If critical errors are found in any of the phases, the DBCC CHECKDB command terminates immediately. This happens when the SQL Server database is badly corrupted, and is beyond the repairing capabilities of DBCC CHECKDB command. In such cases, if you need to access the database records, then you will need to restore the database records from a valid backup. But, if no backup is available or backup falls short to restore the required amount of data, then you will need to repair the database by using advanced MS SQL Repair application.

Consider a practical scenario, where you receive the below error message when you attempt to access one of your table records:

“Table error: Object ID O_ID1, index ID I_ID1 cross-object chain linkage. Page P_ID1 points to P_ID2 in object IDO_ID2, index ID I_ID2.”

The above error message primarily results in inaccessibility of all the table records. Additionally, the error message pops up every time you attempt to access the table records.

Cause:

The above table error message occurs when the next page pointer of P_ID1 page points to different object. This can happen either due to logical corruption factors or physical crash of a system component.

Resolution:

The above error message can be resolved by the below steps:

Database table corruption, if caused due to physical damage, can be resolved by changing the damaged system component.
For logical table corruption reasons, run DBCC CHECKDB command with appropriate repair clause.

While the physical corruption issues can be resolved easily changing the system component, the probability of logical corruption problems being resolved by DBCC CHECKDB command is slightly less. In such cases, you will need to use advanced SQL Database Recovery application to repair the database table. A SQL Repair software can be easily downloaded from Internet.

MS SQL Database Unmountable Post Logical Corruption

2010-01-13T03:14:00.000-08:00

Corruption in MS SQL database is categorized into two forms – Logical and Physical. While the physical database corruption scenarios include damage of system components, the logical corruption situations only relate to software issues. The outcome for database corruption caused due to either of the two reasons in most cases is, unmountability of the database. An unmountable database does not allow you to access the records stored in the database. In such cases, an up-to-date backup (usually maintained by all the database users) allows you to restore the data and continue with your work. However, there have been thousands of case studies where either the user forgets to create an adequate backup or backup file itself gets corrupt. For such situations, the user needs to search for an effective MS Recover SQL application (for logical corruption) and database repair services (for physical crash scenarios).

Some of the most common logical corruption scenarios after which the database becomes unmountable are mentioned below:

Metadata structure damage
Operating system malfunction
File system damage
Virus attack
Simultaneous modification of same database component
Human errors

To repair the database after it gets corrupted due to any of the above reasons, you will need to run DBCC CHECKDB command. This command allows you to identify the level of corruption. Next, you will need to execute the same command with an appropriate repair clause.

While the above command allows you to repair database corruption in most of the situations, it might fail to repair in case the database is severely corrupted. For such situations, in case of no backup availability, you will need to use advanced third-party SQL Database Repair application. A MS SQL Recovery tool instantly repairs corrupt databases post any logical corruption scenario. It uses intensive scanning methods to scan and repair corrupt MS SQL databases. The read only software do not overwrite, change, or delete the data stored in the original database. Built with highly interactive user documentation, these tools are easy to understand and implement.

Fixing “Incorrect PFS free space information...” Error Message

2010-01-08T01:04:00.000-08:00

An MS SQL Server database file is divided into various PFS (Page Free Space) intervals, approximately 64 MB in size. The byte-map of the PFS page consists of at least one byte per page for every page that is included in the PFS interval. The information stored in the PFS interval is very critical because corruption of it can result into database error, which stops you from accessing the records stored in the database. In such situations, the database corruption can be surmounted by restoring the data from an updated backup. However, the possibilities of database users forgetting to create an adequate backup, or the location where the backup is saved always exits. In such cases, the database user needs to opt for a powerful third-party SQL Database Recovery utility that can easily repair the database.

Picture a scenario, where you receive the underneath error message with your MS SQL Server database:

“Incorrect PFS free space information for page P_ID, object ID O_ID, index ID I_ID, in database ID DB_ID. Expected value PFS_VAL1, actual value PFS_VAL2.”

The above error is marked as “Error 8914” in SQL Server log and is a “Severity Level 10” error message.

Cause:

The above error message pops up when the bits allocated in the PFS page conflict with the free space available on the page P_ID. This can either occur due to logical or physical damage of the database.

Resolution:

The resolutions for the above error message are discussed below:

To check for hardware damages, check the system's hardware by examining the log reports of SQL Server and Windows. Change the hardware component in case any component is damaged.
If the problem persists, run DBCC CHECKDB command (with repair clause) to repair the corrupt database.

However, there is a possibility of data loss after running the above command. To avoid such situations, you should repair your database using effective SQL Repair software. These SQL Repair tools perform a complete scan and restore the repaired database on new or old destination. Such tools are completely non-destructive in nature.

Fixing “Database error...” post SQL Database Corruption

2010-01-07T03:58:00.000-08:00

PFS (Page Free Space) pages in SQL Server database not only maintains free spaces, but a lot more than that. Every SQL database file is divided into various PFS intervals, each containing 8088 pages. A PFS page contains a byte-map, which stores one byte for every page included in the PFS interval. Corruption in PFS page results into damage in the stored bytes, further resulting in making your database unmountable. The database records saved in the database become inaccessible after it becomes unmountable. For easy accessibility of records and to save your valuable time, you will need to restore the data from a valid backup. However, in case of backup unavailability or corruption, you will need to use a third-party MS SQL Recovery tool, which provides systematic repair.

As a practical example, you receive the below error message while mounting your SQL database:

“Database error: Page P_ID1 is marked with the wrong type in PFS page P_ID2. PFS status 0xVAL1 expected 0xVAL2.”

The appearance of the above error message makes your database unmountable, further resulting into inaccessibility of its stored records.

Cause:

The above error message appears when the below bits are improperly set:
PFS_IS_IAM_PG (0x10)
PFS_IS_MIXED_EXT (0x20)
PFS_IS_ALLOCATED (0x40)

Damage in PFS pages can occur either due to logical or physical reasons.

Resolution:

To read your database records and to resolve the error message, you will need to follow the below measures:
If the above error arises due to physical damages, then you need to swap the damaged system component with a new component.
However, if the message arises due to logical corruption, then you will need to run DBCC CHECKDB, with appropriate repair clause.

While the first resolution provides 100% guarantee to resolve all physical damages, the second falls short to prove successful in all logical corruption scenarios. For such cases, only a third-party SQL Repair application should be used. These SQL Repair utilities systematically scans a logically corrupted database and restores it on default or new destination. Such repair software are self-explanatory and can be easily used by even non-technical users.

SQL Server database corrupt post Unexpected Shutdown

2010-01-05T03:54:00.000-08:00

Database corruption after unexpected system shutdown is a common scenario happened to almost all of us. The database becomes unmountable, further resulting in inaccessibility of records, after being corrupted. In most of these situations, you receive an error message that describes the exact cause of corruption, and sometimes its resolution too. However, if the resolution provided in the error message works, then there is no need to worry. But if in case, the resolution fails, then the best way to overcome database corruption is by restoring the data from an updated backup. Unavailability of a valid backup leaves you with no option, but to use advanced third-party MS SQL Recovery application to repair the database.

Consider a practical scenario, where your database unexpectedly stops and restarts again. On the restart, the database does not mount, and you view the below error messages in the error log file:

“DateTimeSPID Error: 602, Severity: 21, State: 30.
DateTimeSPID Could not find an entry for table or index with partition ID 491897996509184 in database 2. This error can occur if a stored procedure references a dropped table, or metadata is corrupted. Drop and re-create the stored procedure, or execute DBCC CHECKDB.
DateTimeSPID Error: 9001, Severity: 21, State: 5.
DateTimeSPID The log for database 'msdb' is not available. Check the event log for related error messages. Resolve any errors and restart the database.
DateTimeSPID Error: 3449, Severity: 21, State: 1.
DateTimeSPID SQL Server must shut down in order to recover a database (database ID 1). The database is either a user database that could not be shut down or a system database. Restart SQL Server. If the database fails to recover after another startup, repair or restore the database.”

Cause:

Unexpected shutdown could be caused when SQL Server is unable to handle duplicate partition Ids, which are produced in tempdb database.

Resolution:

To resolve database corruption, you will need to opt for advanced MS SQL Repair tool. These tools use advanced scanning methods to repair your database. Such SQL Repair tools do not require any technical skills to perform database repair.

Error Messages while restoring the MS SQL Server database

2010-01-02T02:26:00.000-08:00

Restoration of data from an updated database backup allows you to overcome almost all SQL Server database corruption scenarios. It is therefore, always recommended to maintain a systematic database backup on some other storage media as well. While restoration of data is an easy process, it might result into an error message, which prevents you from restoration of the database. In such situations, an easy way is to restore the data from any other updated database backup. However if in case, no other backup is available or backup falls short to restore the data, then you will need to opt for advanced third-party SQL Recovery application.

Consider a practical scenario, where you encounter the underneath error message while restoration of data:

“Msg 8967, Level 16, State 216, Server , Line 2
An internal error occurred in DBCC which prevented further processing. Please contact Customer Support.
DBCC results for ''.
Msg 8921, Level 16, State 1, Server , Line 1
Check terminated. A failure was detected while collecting facts. Possibly tempdb out of space or a system table is inconsistent. Check previous errors.”

On viewing the your SQL Server log, you view another error message:

“2007-05-26 07:13:49.21 spid58 DBCC encountered a page with an LSN greater than the current end of log LSN () for its internal database snapshot. Could not read page (file id:page id), database '), LSN = (), type = 32, isInSparseFile = 1. Please re-run this DBCC command.”

While the restoration process halts, the data stored in the database becomes inaccessible.

Cause:

The above error message primarily occurs when the DBCC CHECKDB command is unable to serve the required checks that confirm the consistency of your database. These checks could not be performed due to numerous reasons, such as SQL Server database corruption, metadata structure damage, and more.

Resolution:

To resolve the above error message and to access the database records, you will need to use advanced SQL Database Recovery tool that provides comprehensive repair of corrupt database. Such SQL Repair tools are non-destructive in nature as they do overwrite or modify the original records of the database.

Resolving “Page errors on the GAM...” Error Message

2009-12-27T23:09:00.001-08:00

The metadata structure of Microsoft SQL database is divided into numerous allocation units, such as, IAM (Index Allocation Map) pages, GAM (Global Allocation Map) pages, SGAM (Shared Global Allocation Map), or PFS (Page Free Space) pages. Corruption in any of the above pages primarily results into unmountability of database, further resulting into inaccessibility of database records. In addition, you receive an error message that states the exact cause of corruption. Few main reasons for metadata structure corruption could be unexpected system shutdown, SQL Server damage, virus hit, and human errors. To resolve all corruption scenarios and to access the database records, you will need to use restore the data from an updated backup. But there are millions of case studies proving that most of the database users forget to create a database backup. In such situations, these users need to use advanced SQL Recovery application.

As a practical case, you receive the underneath error message when you attempt to mount your MS Access database:

“Page errors on the GAM, SGAM, or PFS pages do not allow CHECKALLOC to verify database ID DB_ID pages from P_ID1 to P_ID2. See other errors for cause.”

The same error message appears repeatedly each time you attempt to mount your database. The above error message is a severity level 16 error message and can be caused either through logical or physical damage.

Cause:

The root cause for the occurrence of the above error message is corruption in GAM, SGAM, or PFS pages.

Resolution:

The error message can be resolved by using any of the below methods:
If caused due to physical damage, change the damaged system component with a brand new system component.
In case of logical damage, run DBCC CHECKDB command, with correct repair clause.
If both the above resolutions fail, restore the data from an updated backup.
However, if case of absence of a valid backup, repair the corrupt database using advanced SQL Database Repair utility. Such SQL Database Recovery utilities are competent enough to repair corrupt databases in all logical corruption scenarios. Database repair through these tools can even be performed by a non-technical user.

SQL Recovery is an efficient SQL Repair tool to surpass all SQL database corruption scenarios. The software incorporates advanced scanning methods to repair database created in SQL Server 2008, 2005, and 2000. It is designed for Windows 7, Vista, XP, 2003, 2000 and NT.

Table Corruption Post Meta data Structure Damage

2009-12-23T03:29:00.000-08:00

Tables in MS SQL Server database act as a major storage component to save records with different data types. The data stored in the tables can be easily viewed by running a query. However, in some situations (when you receive an error message), the query may not display the desired records. One of the main reasons for the occurrence of the error message is corruption of table. The error message message halts the extraction of records, making them totally inaccessible. To access the records stored in the table, an easy way is to restore them from an updated backup. However, if the backup is not available, then you will need to repair the corrupt table. To do so, you will need to search for an advanced SQL Recovery application.

Picture a situation, where you receive the below error message when you attempt to access the records stored in a MS SQL Server database table:

“Table error: Object ID O_ID, index ID I_ID. Index node page P_ID1, slot S_ID1 refers to child page P_ID2 and previous child P_ID3, but they were not encountered.”

After the above error message appears, all the table records become inaccessible. Furthermore, the error message appears at every attempt of accessing the table records.

Cause:

The above error message pops up when the table gets corrupted due to metadata structure damage. The result of damage is that the index page in a B-tree can not see its child references, which are neighboring to its two lower pages.

Note: Database corruption can either be caused due to logical or physical factors.

Resolution:

For systematic resolution of the above error message and repair of corrupt table, you will need to follow underneath measures:
Physical damages can be surmounted only by changing the damaged system object with a new object.
Logical corruption can be surpassed by running DBCC CHECKDB command.
In case the problem persists even after running DBCC CHECKDB command, then you will need to repair your database table using an advanced SQL Database Repair software.

A SQL Database Recovery utility ensures comprehensive repair of corrupt database components by incorporating powerful scanning methods. In addition, these tools perform safe repair, without making any changes in original records saved in table.

How to Resolve “Database ID DB_ID, object 'OBJNAME' (ID O_ID)...”

2009-12-21T22:40:00.001-08:00

The main purpose of DBCC CHECKDB command in MS SQL is to check the integrity (logical and physical) of all the specified database objects. The command performs three operations (DBCC CHECKALLOC, DBCC CHECKTABLE, and DBCC CHECKCATALOG) to comprehensively repair the corrupted database. While the repair command repairs your database in most situations, it might fail to repair in case of damage of critical system tables. In such circumstances, an easy way is to restore the data from an updated database backup. But in case of absence of an updated backup or the backup file itself getting corrupted, then you will need to search for advanced SQL Database Recovery application that can repair your database.

Consider a practical situation, where you receive the below error message when you attempt to mount your database:

“Database ID DB_ID, object 'OBJNAME' (ID O_ID). Loop in data chain detected at P_ID.”

After the above error message pops up, your database becomes unmountable. Furthermore, the data stored in your database becomes inaccessible.

Cause:

The root cause for the occurrence of the above error message is corruption in metadata structure of SQL database. Corruption can occur by both logical or physical reasons.

Resolution:

To resolve the above error message and to access the database records, follow the below three measures:

Swap the physically damaged system component with a new component.
Execute DBCC CHECKDB command (with appropriate repair clause.)
Restore the data from an updated database backup.

Out of the above three measures, the first measure provides complete resolution from the physical damage situations. The other two measures fail to perform in case the database is severely corrupted or there is no backup available. In such situations, the only alternative left is advanced SQL Repair software.

Such SQL Recovery tools ensure complete repair of most corrupted SQL databases. These applications come with interactive user documentation that makes the database user to easily understand the repair process. These repair tools are non destructive in nature.

Tips to resolve “Table error: Object O_ID... page P_ID was not encountered.” Error

2009-12-19T02:00:00.000-08:00

The records in Microsoft SQL Server database can be placed and located in the form of a B-tree. These records are divided into various pages (child pages), each having a unique index page, which is one level up in hierarchy from the child page. Corruption in the hierarchical tree structure (metadata structure corruption) primarily results in loosing the reference of the child page from the Index page. In such situations, the data stored in the database becomes inaccessible. For accessing the data stored in the database, an ideal way is to restore it from an updated database backup. But if in case of absence of an valid database backup, you will need to use advanced MS SQL Database Recovery application to repair your database.

Consider a practical scenario, where you receive the below error message when you attempt to access the records stored in table:

“Table error: Object ID O_ID, index ID I_ID. Parent node for page P_ID was not encountered.”

The above error message makes the data stored in table inaccessible. Moreover, the error message repeatedly repeats every time you attempt to access the records stored in the table.

Cause:

The root cause for the occurrence of the above error message is SQL database corruption due to metadata structure damage.

Note: SQL database can be corrupted either due to logical or physical factors.

Resolution:

To resolve the above error message and to access the table records, you will need to follow the below measures:
To solve all the corruption issues caused due to physical damage, swap the corrupt system component with a new component.
To solve all the corruption issues caused due to logical damage, run DBCC CHECKDB command with correct repair clause.

The first measure is competent enough to resolve all the physical damage issues. The second measure, however, fails to resolve all logical corruption problems. For such situations, the database table can be repaired by using advanced MS SQL Recovery software. These SQL Repair utilities employ effective scanning methods to completely repair the corrupt table after all logical database corruption scenarios.

Resolving “Missing or invalid key in index...” Error Message

2009-12-17T22:43:00.001-08:00

In SQL Server database, the data is primarily organized in two kinds of non-system pages – data pages (consist of data rows) and Index pages (consist of index rows). For every data row in a data page, there is always a pre-defined matching index row in Index page. However, if the index row is missing or corrupt, then you receive an error message that results into unmountability of your database. Records stored in an unmountable database are inaccessible. To access the records and continue with your work, you will need to use the data from an updated database backup. But if in case, the database backup has been corrupted or damaged, then you will need to use powerful third-party SQL Database Recovery application that can repair the database.

Consider a practical situation, where the below error message appears when you attempt to access the records stored in SQL database table:

“Table error: Table 'OBJNAME' (ID O_ID). Missing or invalid key in index 'INDEXNAME' (ID I_ID) for the row”

The above error message makes the records stored in your table inaccessible. Furthermore, the above error message pops up every time you attempt to access the table records.

Cause:

The fundamental cause for the occurrence of the above error message is missing of Index row.

Note: The above error message can be caused due to logical or physical corruption in SQL database table.

Resolution:

There are different ways to resolve corruption caused due to different reasons. These ways are discussed underneath:
Resolve the physical damage issues by swapping the damaged system component.
Resolve the logical damage problems by running DBCC CHECKDB command, with appropriate repair clause.

While the first resolution guarantees complete resolution from all physical damage scenarios, the second fails to repair database table in all logical corruption situations. For complete repair of tables after all logical corruption cases, you will need to opt for efficient SQL Recovery software. Such SQL Repair tools use powerful scanning methods to repair and restore the repaired table on default or user-specified location.

Resolving “Row error: Object ID....created NOT NULL, but is NULL in the row ”

2009-12-16T01:52:00.000-08:00

SQL Server database corruption can have severe effects on the records stored in database components. One of the effect that most database users might encounter is wrong values being displayed under a particular column. Few major causes for database corruption can be improper system shutdown, SQL Server malfunction, virus infection, and more. An easy way to access data after corruption due to any of the above reasons is to restore the data from an updated backup. However, there might be circumstances where you have either not created any backup or backup itself is damaged corrupted. In such situations, you will need to search for advanced MS SQL Repair application that can systematically repair your corrupted database.

For example, the below error message pops up each time you attempt to mount your SQL Server database:

“Row error: Object ID O_ID, index ID I_ID, page ID P_ID, row ID S_ID. Column 'COLUMN' was created NOT NULL, but is NULL in the row.”

As the error message states, the columns which had NOT NULL values, now hold NULL values. The above error is 'severity level 16' message and can occur either due to software or hardware corruption issues.

Resolution:

The above error message can be resolved by following underneath error messages:

To isolate the problem caused due to physical damage of the system component, you will need to swap out the damaged system components with new components.
To completely resolve the issues created due to logical damage, you will need to execute DBCC CHECKDB command with appropriate repair clause.
Restore the database by using an updated database backup.

While the above resolutions are helpful in most of the issues, they fail in below situations:

DBCC fails to repair
Unavailability of database backup

To overcome both the above database corruption issues, you will need to use effective SQL Database Recovery software. Such SQL Repair tools thoroughly scan your database and allow you to restore the repaired database at user-specified location. These tools can be easily understood even by novice user.

Resolving “IAM page P_ID ... that should be in filegroupFG_ID2” Error Message

2009-12-14T21:42:00.000-08:00

Mapping of MS SQL Server database is performed over a group of operating system files. The information related to data and logs is kept in different files, while single files are handled only by one database. The collections of all these files is known as filegroup. Two major functions that every filegroup performs are placement of data and administrative tasks. Corruption in any of the filegroups primarily results in unmountability of your database, which further results in inaccessibility of database records. To access your records after your SQL Server database becomes unmountable, a simple way is to restore the data from an updated database backup. But in weird situations where you have not created any backup or backup falls short to restore the records, you will need to start searching for an advanced third-party MS SQL Repair application.

Picture a scenario where you attempt to access the data saved in one of your SQL Server database, an you receive below error message:

“IAM page P_ID for object ID O_ID, index ID I_ID controls pages in filegroup FG_ID1, that should be in filegroupFG_ID2.”

Database records stored in your database do not appear because the above error message does not allow the database to mount. In addition, you repeatedly receive the above error message each time you attempt to access the database records.

Cause:

The root cause for occurrence of the above error message is damage of filegroup. Corruption can occur either due to logical or physical reasons.

Resolution:

Below are two measures that allow you to access database records:

Swap the physically damage component with a new component to overcome all physical damage issues.
Run DBCC CHECKDB command to surmount all logical issues.

Although the above resolutions prove successful in most cases, the possibility overcoming all logical corruption scenarios by using DBCC CHECKDB command is slightly less. In such situations, a powerful SQL Database Recovery application enables you to repair your corrupt database and access it records. Such SQL Repair tools use advance repairing procedures to thoroughly scan and repair the corrupt database.

Tips to Resolve “Database 'DBNAME' consistency errors...” Error Message

2009-12-14T01:10:00.000-08:00

DBCC CHECKDB command is used to check the physical and logical integrity of MS SQL database objects. It is a three-stage process that performs DBCC CHECKALLOC, DBCC CHECKTABLE and DBCC CHECKCATALOG operations on the specified database. The command also validates the service broker data, contents of every indexed view, and link-level between file system directories and table metadata. While DBCC CHECKDB command repairs your SQL Server database in most situations, it might fail to perform under numerous circumstances. In such cases, an ideal way to is to restore the data from an updated database backup. But if in case, there is no database backup available or backup falls short to restore the lost data, then you will need to use advanced MS SQL Repair software.

As a practical scenario, you encounter the below error message while attempting to mount your Employee database:

“Database 'Employee' consistency errors in sysobjects, sysindexes, syscolumns, or systypes prevent further CHECKNAME processing.”

Above error message makes the data stored in the database inaccessible.

Grounds for the Error:

Corruption of Employee database either due logical or physical reasons.

Resolution:

To access the Employee database records and comprehensively resolve database corruption, you will need to follow the below measures:

To surmount damages caused due to physical damage of the system component, you will need to switch to a new system component. This can also include reinstalling the operating system.
To overcome the damages caused due to logical corruption, you will need to run DBCC CHECKDB command.

While DBCC CHECKDB command provides complete repair in most situations, it fails to perform when it finds error in Stage 2 (while running DBCC CHECKTABLE). This means that your system tables have been corrupted and DBCC CHECKDB can not repair your database. In such situations, the only way to repair your database is by using advanced SQL Database Recovery software.

Resolving “Text node referenced by more than one node” Error Message

2009-12-08T01:33:00.001-08:00

Data, such as, tables, views, etc in SQL Server database is stored in blocks of 8Kb known as Pages. The two ways in which these Pages can be organized are clustered and non-clustered tables. While in clustered table the pages are linked in a doubly-linked list, the pages in non-clustered table may not be linked. Corruption in clustered table can damage the linking of the pages, further resulting in the unmountability of the SQL database. The records stored in the pages become inaccessible once the SQL Server becomes unmountable. For comprehensive accessing of all records in such situations, you will need to restore the data from an updated database backup. But if in case, the backup is corrupt, unavailable, or not even created, then you will need to use advanced third-party SQL Recovery application.

As a practical instance, you encounter the below error message while trying to access the records saved in a particular table:

“Text node referenced by more than one node. Object ID O_ID, text, ntext, or image node page P_ID1, slot S_ID1, text IdTEXT_ID is pointed to by page P_ID2, slot S_ID2 and by page P_ID3, slot P_ID3.”

Your database becomes unmountable after the above error message appears. Additionally, the error message pops up every time you attempt to access the table records.

Cause:

The reason responsible for the above error message is internal errors related to three pages involved in the above error message. These internal errors could be caused either due to physical or logical crash scenarios.

Resolution:

Below steps enable you to resolve the problem and access your database records:

Check for physical damage of the system component. If required, change the damaged system component
If the problem persists, run DBCC CHECKDB using appropriate repair clause to repair your database.
However, if the error message still appears and no backup is available, then you will need to use powerful SQL Database Repair tool. These MS SQL Repair applications use intensive scanning methods to and repair databases and recover all database components. Such tools are completely non-destructive in nature.

How to Resolve “CHECKTABLE processing of object ID...” Error Message

2009-12-07T04:07:00.000-08:00

DBCC CHECKTABLE command in SQL Server database is used to check your database table for errors. The command creates a mini dump file in the SQL Server Log Directory whenever it detects that the table is corrupt or damaged. If you wish to access the records saved in the table in such scenarios, then you will need to restore the data from an updated backup. However, if in case the backup is not available or backup falls short to restore the table records, then you will need to search for advanced SQL Server Recovery application.

As a practical case, you view the below error message in mini dump file after you run DBCC CHECKTABLE command to check your table:

“CHECKTABLE processing of object ID O_ID, index ID I_ID encountered page P_ID, slot S_ID twice. Possible internal error or allocation fault.”

Your table records become inaccessible after the above error message appears.

Cause:

The root cause for the above error message is encountering of Page P_ID during the course of scanning.

Note: Table corruption can occur either due to logical or physical damage.

Resolution:

To resolve the above error message and to access table records, you will need to follow the below steps:

Restore the data from an complete backup.
In case of physical damage, change the damaged system component.
For logical corruption scenarios, run DBCC CHECKDB using appropriate repair clause.

Swapping the damaged system component provides complete resolution from all physical damage scenarios. The other two resolution fail to perform under tow scenarios:

The backup is unavailable.
Severe Corruption of the database.

To repair your corrupted database in the above scenarios, you will need to search for an efficient SQL Database Repair tool. These MS SQL Repair applications are developed by talented data recovery experts and repair databases after almost all logically corrupted SQL databases. These repair tools use high-end scanning methods to repair and restore the recovered database components on default or user-defined destination. These read only nature of these database repair applications ensure risk-free repair of database, leaving the original database file untouched and unmodified.

Resolving “Forward row mismatch” Error message

2009-12-05T03:27:00.000-08:00

In SQL Server database, rows of a table are divided and stored into a series of partitions. These rows can either be saved in heap or B-tree structure. In heap tree structure, the table does not contain any Index and the forward row always points back to the forwarding row. However, in B-tree structure the rows are saved in accordance to the Index values. Corruption in metadata structure of your SQL database results in changing the values of these rows, thereby resulting in inaccessibility of all database records. An easy way to surpass such corruption scenarios is by using restoring the data from an updated backup. But, the possibility of backup being corrupted or damaged always exist. In such situations, an ideal way is to repair your database by using an effective SQL Server Recovery software.

Consider a scenario, where the underneath error message pops up every time you attempt to mount your database:

“Forwarded row mismatch: Object ID O_ID, page P_ID1, slot S_ID1 points to forwarded row page P_ID2, slot S_ID2; the forwarded row points back to page P_ID3, slot S_ID3.”

Your database records become inaccessible after the above error message appears.

Cause:

The main reason of the above error message is that the forwarded row (S_ID2 on page P_ID2) instead of pointing to forwarding row (S_ID1 on page P_ID1), is pointing to the wrong row.

Note: The above case can occur due to both logical and physical corruption scenarios.

Resolution:

The resolution for the above error message is mentioned below:

Swap the system component that is damaged with a new component.
Execute DBCC CHECKDB command.

While the former resolution to overcome hardware related issues is perfect, the later solution might fail to resolve logical corruption issues. For complete and systematic resolution in all logical corruption scenarios, you will need to opt for advanced SQL Database Repair tool. Such tools provide maximum MS SQL Repair by employing high end scanning and repairing algorithms. These tools are non-destructive and perform recovery without making any changes in the original database file.

Database Suspect due to Problems while Transaction Commit

2009-12-03T01:57:00.001-08:00

A commit transaction in SQL Server is primarily used to make all the changes permanent which you performed since the start of transaction. Once you run the commit statement, all the resources held by the transaction are freed and the value for TRANCOUNT is set to “0”. Interruption while processing of commit transaction can result into making your database suspect. In such situations, your database becomes unmountable and the records stored in it become inaccessible. For complete access of database records after it has been corrupted, you will need to restore the data from an updated database backup. However, if the database backup is corrupted or unavailable, then you will need to use advanced third-party SQL Recovery application that can systematically repair your corrupted database.

A commit transaction can be halted due to below reasons:

A SQL Server CE application closes unexpectedly.
Windows CE device is reset.
SQL Server CE does not respond.

Your database is marked suspect after any of the above problem occurs. Furthermore, this leaves your database in an unrecoverable state. The above problems occur either due to power failure or an explicit reset during a transaction. Below are some prevention measures that enable you to minimize the effect of the problem:

Ensure that you have maintained a backup copy of your SQL Server CE database files.
To prevent database users from performing an explicit reset while a data manipulation process is in progress, add a progress bar in your application.
Always try to keep your transactions short.

Resolution:

To make your database records accessible, you will need to use Compact method. While the method repairs the database in many cases, chances of database corruption still exists. In such situations, the only way left to repair your database is by using advanced SQL Database Repair application.

These database repair utilities employ intensive scanning methods to repair your corrupted database and recover almost all database components. With highly-interactive user documentation, the MS SQL Repair software guides you through a complete repair process. The non-destructive software provides safe recovery of database components and provides an option to save them on default or new destination.

How to Resolve “Could not read and latch...” Error Message

2009-11-30T03:21:00.001-08:00

Data storage space in SQL database is primarily divided into numerous pages. Each page contains a 96-byte header that contains information related to page number, page type, ID, and free space. Corruption in metadata structure primarily results in failing to read the data stored on the page. This further results in making the data stored in the database inaccessible. In such situations, the data stored in the database can be accessed by restoring it from an updated backup. However, there have been instances where the backup has not been created or the backup file is corrupted due to various logical and physical factors. For accessing your database records under such circumstances, you will need to search for an advanced third-party Recover SQL application.

Consider a practical scenario, where you encounter the below error message when you attempt to mount your SQL database:

“Could not read and latch page P_ID with latch type TYPE. OPERATION failed.”

The above error message appears each time you attempt to access the database records. Furthermore, the above error message makes the database records inaccessible.

Cause:

The root cause for the occurrence of the above error message is the failure of page read due to any of the below reasons:

The page is in repairing state.
An indeterminate function is being performed on the page.
The page might be read as a part of per checks of important system tables.

Note: The above scenarios can occur due to both logical and physical reasons.

Resolution:
To resolve the above error message and to execute your database records, you will need to
swap the damaged system component with a new one (for physical damages). For logical crash scenarios, you will need to run DBCC CHECKDB command (with correct repair clause).

Changing the damaged hardware component provides comprehensive solution to get rid of all hardware problems. But, in case of removing logical corruption scenarios, DBCC CHECKDB is not always a complete solution. For permanent resolution of all corruption scenarios, you will need to use a powerful SQL Database Repair application. Such MS SQL Repair software orderly perform database repair and recover all lost database components.

How to Resolve “Extent E_ID in database ID...” Error Message

2009-11-25T03:04:00.001-08:00

The structure of an Index Allocation Map (IAM) page in MS SQL Server consists of one bit per dedicated extent for all the “Extents” in the file interval. The bit is allocated to the index of which the IAM page is a part. Corruption in the bit can result into inaccessibility of records stored in your database. Few major causes of corruption of the application damage, metadata structure corruption, malicious software like virus, and human errors. To access your data in such situations, restoration from an updated and valid database backup always helps. However, if the restoration could not be performed due to backup corruption, then the only way to access your data is by using advanced third-party SQL Server Recovery application.

Consider a practical scenario, where the underneath error message appears when you attempt to mount your SQL database:

“Extent E_ID in database ID DB_ID is allocated to more than one allocation object.”

The above error message halts the database mounting process making all the records saved in it inaccessible.

Cause:

The fundamental reason responsible for the occurrence of the above error message is bit corruption that results in the allocation of same extent to two different IAM pages.

Note: The above error message can also occur due to physical damage of your system's component.

Resolution:

To resolve the above error message and to access the database records, take the below measures:

In logical crash circumstances, run DBCC CHECKDB command (with appropriate repair clause).
The physical damages can only be resolved by making the swapping the damaged component with the new component.

While the above resolution for physical damage is always successful, the DBCC CHECKDB does not provides complete surety of repairing database after all logical crashes. To permanently resolve all logical corruption scenarios, you will need to use advanced SQL Repair tools. Such SQL Database Repair applications are built by highly talented database recovery experts and use high end repairing methods to repair your database. These tools come with interactive user documentation, that makes them easy to understand without any prior technical understanding.

Nothing can be more frustrating than the inaccessibility of records stored in your database. There can be numerous reasons responsible for corruption, such as, metadata structure damage, MS SQL Server unexpected shutdown, virus attack, and more. A perfect resolution to get rid of all the corruption scenarios is by restoring the data from an updated database backup. But, there might be situations where you have either not created any backup or your backup has been damaged. These circumstances force you to use advance third party Recover SQL application that can easily repair your corrupted database.

As a practical scenario, you receive the underneath error message when you attempt to access the records stored in your SQL database:

“Table error: PAGETYPE page P_ID (object ID O_ID, index ID I_ID) is out of the range of this database.”

The above error message makes the database unmountable eventually resulting in the inaccessibility of records. Furthermore, the same error message pops up every time you attempt to access the database.

Cause:

The root cause for the occurrence of the above error message is that the IAM (Index Allocation Map) page is beyond the use of the file in which it is stored. This happens when the page maps an invalid interval or the first IAM page for an index is allocated as PageId_NULL.

Note: The above error message can occur due to both logical or physical damage.

Resolution:

Underneath are the resolutions that help you to resolve the error caused due to either logical or physical reasons:

Run DBCC CHECKDB command to in case of logical corruption.
Thoroughly examine the application the application and Microsoft Windows system logs to identify physical damage. In case, the logs specify the physical damage, then connect the hardware.

While the above resolutions prove successful in most situations, the possibilities of DBCC CHECKDB command falling short always exists. In such cases, you will need to opt for advanced SQL Repair software. Such SQL Database Repair are easy to understand by both technical and non-technical users as they are built with highly interactive user-interface.

Resolving “IAM page P_ID1 is pointed to by the previous pointer...” Error Message

2009-11-20T03:55:00.000-08:00

An Index Allocation Map (IAM) page in MS SQL Server database act as a storage component to save information related to table extents and indexes. A single IAM page contains of two records – IAM page header and bitmap – and has the capacity to track 4GB of space to store. A linked list of all the IAM pages – IAM chain – tracks the space assigned to every single entity. Corruption in IAM chain primarily results in unmountability of SQL database. An unmountable database means inaccessibility of all the records. To access your records after IAM chain corruption, restore the data from an updated database backup. But, in absence of an updated backup or backup falling short to restore the required data, you will need to use advanced MS SQL Recovery application to repair your database.

Here is an instance to prove the above point. Consider a scenario, where you receive the below error message when you attempt to mount your database:

“IAM page P_ID1 is pointed to by the previous pointer of IAM page P_ID2 object ID O_ID index ID I_ID but was not detected in the scan.”

This error message stops the mounting process of your database resulting in making the records inaccessible.

Cause:

The above unmountable error message primarily occurs when the metadata entry in the IAM chain goes missing. This usually occurs due to metadata structure corruption.

Resolution:

The resolution for the above error message can be found out by following the below measures:

For logical corruption situations, you will need to run DBCC CHECKDB command (with repair clause) to repair your database.
For physical damage cases, you will need to examine the SQL Server and Microsoft Windows system logs. These logs help you to find the exact cause of damage. To permanently rectify the problem, change the damaged component with a new one.

While all the logical corruption scenarios can be solved using the above repair statement, there are still some possibilities of the database being not repaired. In such situations, if you want to repair your database, you will need to use a powerful third-party SQL Repair tool. Such SQL Database Repair applications are developed by highly qualified data recovery engineers and employ high end scanning methods to repair logically corrupted database.

Two main building blocks of every MS SQL database are pages and indexes. These pages store actual data and are always marked by a header that stores information such as, page number, page type, and free space. The page type in header section saves the data (Index, allocation map, etc.) that define the page. Corruption in the header might occur due to numerous factors, resulting into inaccessibility of records stored in the database. In most cases of SQL database corruption, you encounter an error message. To surmount the error message and access the SQL database records, you will need to restore the data from an updated backup. However, if the database backup file is corrupted, damaged, or inaccessible, then you will need to use advanced SQL Repair software.

Below is the error message that appears after the header gets corrupted or damaged:

“Table error: Page P_ID with object ID O_ID, index ID I_ID in its header is allocated by another object.”

The above error message appears every time you attempt to access the database records. In addition, the database records become inaccessible after the above error message appears.

Cause:

The above error message primarily occurs when a page contains a Index ID but is not allocated by any of the index's IAM pages. This happens in case of Index corruption, caused by either logical or physical crash.

Resolution:

Underneath are the resolutions for database repair caused due to logical or physical issues:

For logical crash circumstances, run DBCC CHECKDB command (with recommended repair clause) to repair your database.
For physical crash situations, examine the application and Microsoft Windows system logs. These logs enable you to determine the hardware responsible for damage. Swap the damaged hardware with a new one.

While physical damages can be convincingly solved by changing the hardware component, DBCC CHECKDB does not provide comprehensive repair in all cases. To repair your database is such situations, you need to have an advanced SQL Repair software. Such SQL Server Recovery software ensure complete repair after all the logical corruption scenarios by using intensive scanning and repairing techniques.

Tips to Resolve “Table error: Page P_ID...” Error Message

2009-10-20T04:50:00.001-07:00

Every page in SQL Server database contains a unique object and index ID stored in its header. Corruption in object or index ID makes the records saved on that page inaccessible. Few scenarios under which the corruption can take place are improper system shutdown, virus attacks, and human errors. To overcome such situations, an easy way is to restore the data from an updated backup. But if in case, you have not created any database backup or backup falls short to restore the required records, then you will need to opt for advanced SQL Server Recovery software that can repair your database and allow you to access the records.

Consider a practical case, where you encounter the below error message when you attempt to view some records saved on a particular table:

“Table error: Page P_ID with object ID O_ID, index ID I_ID in its header is allocated by another object.”

The above error message makes the data stored in the table inaccessible. Additionally, you encounter the same error message each time you attempt to view the records saved in that table.

Cause:

The above error message can occur due to various hardware and software issues.

Resolution:

In case of hardware issues, run hardware diagnostics and try to swap the old hardware components. However, if the error message persists even after changing the hardware component, then you will need to firstly run DBCC CHECKDB command – without any repair clause-to determine the extent of corruption. After complete analyses, you will need to run DBCC CHECKDB command with a repair clause.

Note: Performing a repair will rebuild the Index(s) and can result into loss of data.
In most cases, the DBCC CHECKDB resolves your issue and makes the records saved in the table accessible. However, the above command fails and no clean backup is available, then you will need to use advanced SQL database recovery tool to repair the database and access the records saved in the table. These SQL Repair applications incorporate high end scanning methods to scan the hard drive and repair the corrupted MS SQL database. These tools are developed by highly talented data recovery experts and easily understandable without any prior technical knowledge.

Tips to resolve “Error: 0x80004005 E_FAIL ...” Error Message

2009-10-18T23:43:00.001-07:00

Sometimes, when you attempt to open the MS SQL database, you encounter an error message. The error message primarily occurs when the database gets damaged or corrupted. Few main reasons for corruption of database are improper system shutdown, application malfunction, virus attack, and human errors. The error message halts the mounting process of your database and makes the data stored in it inaccessible. To overcome the problems created by error message, an ideal way is to restore data from an updated backup. However, in case of database backup unavailability or backup falling short to restore the required data, the only option left is to repair your corrupted SQL database using a powerful SQL Repair software.

As a practical scenario, you encounter the below error message when you attempt to open corrupted MS SQL database:

“Error: 0x80004005 E_FAIL
Minor Error: (25017)
Description: Unspecified Error”

The error code is SSCE_M_DATABASECORRUPTED (database file or non-database file corrupted).

Additionally, when you use CompactDatabase method to resolve the corruption, you further encounter another error message:

“Error: -2147467259
Compact”

The same error message appears each time you attempt to open your database. Furthermore, the data stored in your database becomes inaccessible after the above error message appears.

Cause:

The fundamental basis for the occurrence of the above error message is the corruption of your SQL database. Therefore, the engine ActiveX code for CompactDatabase method aborts when it attempts to initialize the source database.

Resolution:

To resolve the above error message, you will need to obtain the latest service pack of SQL Server 2000 Windows CE Edition. In most cases, the above resolution resolves the above problem and makes the database accessible.

However, if the above persists even after installing the latest service pack, then you will need to use powerful SQL database recovery software to repair the corrupted database. Such SQL Server Recovery tools employ effective scanning procedures to scan and repair the corrupted MS SQL database. With to-the-point user-documentation and interactive user-interface, these tools serve as self-explanatory and repair-centric applications.

Tips to resolve “Unable to process index...” Error message

2009-10-16T00:02:00.001-07:00

Filegroups in Microsoft SQL Server are primarily used to group database files to use them in an easy and simple way. A system administrator can create particular filegroups for each hard drive attached in the system and assign tables, indexes, text from a particular table to them. While these filegroups can be easily accessed, the possibilities of their corruption always remains. In such situations, the best way to access the data is by restoring it from an updated and valid backup. However, in case of no backup availability or backup failing short of restoring the desired information, then you will need to use advanced SQL Repair software that can completely repair your corrupted database and recover its components.

Consider a practical instance, where you receive the below error message when you attempt to open your SQL Server database:

“Unable to process index I_NAME of table O_NAME because filegroup F_NAME is invalid.”

Cause:

The root cause for the occurrence of the above error message is that filegroup Ids stored in the metadata for an index do not exist, so that index can not be checked.

Resolution:

Below are certain resolutions that enable you to resolve the above error message:

Error 2522 could be a result of hardware malfunction. In this case, you will need to check your computer system, Windows error logs, and SQL server. To resolve the hardware problem, you will need to swap the old hardware components with new hardware components.
However if the error message is not occurring due to hardware problems, then you can restore the database from an updated backup.
But if in case, you have not maintained any backup, then you will need to execute the DBCC CHECKDB command to repair the corrupted database.

In most cases, the above resolutions resolve your issue and your SQL database becomes accessible. But, if all the above resolutions fall short and the error message still remains, then you will need to use advanced SQL Recovery application that can repair your corrupted database. Such SQL Repair tools use high-end scanning methods to repair the corrupted database. Built with highly interactive user-interface, these tools are easily understandable without any prior technical knowledge.
