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 <a href="http://www.rsdatabaserecovery.com/">SQL Recovery</a> solutions. <br /><br />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:<br /><br />“Could not read and latch page P_ID with latch type TYPE. OPERATION failed.”<br /><br />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. <br /><br />Reason:<br /><br />The most frequent causes of this problem with Microsoft SQL Server database corruption can be any of the following ones:<br /><br />• The page that you are trying to access is in the repairing state. <br />• SQL Server is performing an intermediate operation on particular page. <br />• The page is read as the part of every checks of significant SQL database system tables. <br />• The page is too damaged to be recognized by MS SQL Server. <br /><br />You may face this issue due to either logical or physical MDF file corruption. <br /><br />Solution:<br /><br />Use any of the following MDF recovery solutions to work around this issue-<br /><br />• Detect and fix consistency issues using DBCC CHECKDB command. It is an inbuilt SQL repair tool of SQL Server. <br />• Restore database from the latest backup.<br />• When both the above solutions fail to work, go for third-party SQL database recovery software. <br /><br /><a href="http://filerepairtools.weebly.com/sql-recovery-software.html">SQL Recovery</a> 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.Saksham

The corruption usually leads to data loss and put you in need of <a target="_blank" href="http://rsdatabaserecovery.com/"><strong>SQL database recovery</strong></a> solutions.<br /><br /> When the operation fails, you may encounter the below error message that indicates that transaction log is damaged-<br /><br /> <em>Error: 9004, Severity: 21, State: 1.<br />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.</em><br /><br /> 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 <a target="_blank" href="http://rsdatabaserecovery.com/"><strong>SQL</strong> <strong>recovery</strong></a>, you must find the cause of this issue.<br /><br /> <strong>Root of the problem-</strong><br /><br /> 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.<br /><br /> <strong>Resolution-</strong><br /><br /> 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.<br /><br /> 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.<br /><br /> In case none of the above methods work, SQL recovery software come for your rescue. Third-party <strong>SQL database recovery</strong> applications are totally safe and easy to use with read-only conduct and simple graphical user interface.<br /><br /> Such applications effectively handle all database corruption issues.

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.<br /><br />When the above problem of database corruption occurs, you might encounter the following event in the Application Event log of Microsoft SQL Server:<br /><br />"Filestream corruption - missing files, error 7904.<br /><br />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.<br /><br />7904 16 2 Table error: The filestream file for "FileID" was not found."<br /><br />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.<br /><br />Grounds of the issue<br /><br />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.<br /><br />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.<br /><br />In all these cases, you encounter database corruption and need to go for SQL Recovery by repairing and restoring the database.<br /><br />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.<br /><br />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. <span><a style="color: rgb(0, 51, 153);" href="http://creativecommons.org/licenses/by-nd/3.0"><br /></a></span></div></div>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-114924403928591005.post-65689992700543695972010-09-01T04:52:00.000-07:002010-09-01T04:55:05.455-07:00Getting table Error 8925 while working on MS SQL Server 2000 database?<p style="font-family:verdana;"><span style="font-size:85%;">Are you getting some table errors while working on MS SQL Server 2000 database?

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<br />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.<br /><br />For instance, the following error message appears while you are working on an MS SQL Server 2008 database:<br /><br />“Table error: alloc unit ID A_ID, page P_ID. The test (TEST) failed. The values are VAL1 and VAL2.”<br /><br />Cause:<br /><br />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.<br /><br />Resolution:<br /><br />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:<br /><br />Verify the hardware components: You should check the state of the hardware components by the following measures:<br /><br />Check the SQL Server error logs to verify if there is any hardware related error.<br /><br />Swap the hardware components to narrow down on the exact hardware error, if any.<br /><br />Check if the disk controller has enabled write-disk caching. If yes, then take the assistance of the hardware vendor to sort this issue.<br /><br />Format hard drive and reinstall fresh copy of operating system to get a fresh and clean system.<br /><br />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.<br /><br />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.<br /><br />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. Developed for MDF files in MS SQL Server 7.0, 2000, 2005, and 2008, this MS SQL Server repair utility repairs several database objects such as stored procedures, collations, defaults, triggers, tables, NDF files, etc. In addition, this .MDF repair software is compatible with Windows 7, Server 2008, Vista, Server 2003, XP, and 2000.<br /><br />Article Source :- http://www.programmersheaven.com/user/markwillium/blog/5740-How-to-solve-page-header-corruption-cases-in-MS-SQL-Server-2008-database/Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-114924403928591005.post-3628432375506747012010-07-03T04:36:00.000-07:002010-12-29T03:44:41.869-08:00Resolving Error 7965 and recovering corrupt database in SQL Server 2000In SQL Server databases, an Index Allocation Map (IAM) page is a page type that stores the details about the extents, which is a collection of eight pages.

You can easily restore all your valuable data from current backup and prevent needs of <a href="http://www.mssqldatabaserecovery.com/">SQL recovery</a> using third-party applications.<br /><br />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.<br /><br />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:<br /><br />“CHECKDB found 0 allocation errors and 15 consistency errors in database 'mydb'.<br />repair_allow_data_loss is the minimum repair level for the errors found by DBCC CHECKDB (mydb”<br /><br />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.<br /><br />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.<br /><br />In case you run across database corruption and data loss due to any inconsistency error, <a href="http://www.repair-mssql-database.com/">MS SQL repair</a> becomes need of hour.<br />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.<br /><br />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.<br /><br /><br />Article Sources: <a href="http://www.articlecat.com/Article/Minimum-Repair-Option-for-the-SQL-Server-Database-Inconsistency-Issues/403169">http://www.articlecat.com/Article/Minimum-Repair-Option-for-the-SQL-Server-Database-Inconsistency-Issues/403169</a>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-114924403928591005.post-62520100838990486292010-06-03T05:21:00.000-07:002010-06-03T05:22:31.533-07:00How to Resolve 'Error 823' While Accessing SQL Server Database?Are you getting 'Error 823' while accessing an SQL Server database or modifying the 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 <a href="http://www.mssqldatabaserecovery.com">SQL Database Recovery</a> applications to get your database repaired.<br /></div><ul style="text-align: justify;"><li>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. </li></ul><div style="text-align: justify;">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.<br /><br />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:<br /><br />“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?”<br /><br />Or<br /><br />“Incorrect key file ... try to repair it”<br /><br />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.<br /><br />You can easily Recover SQL database with the help of third-party <a href="http://www.mssqldatabaserecovery.com">SQL Server Recovery</a> applications. They come equipped with highly-advanced and efficient scanning techniques to ensure absolute recovery of damaged SQL database.

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.<br /><br />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:<br /><br />“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.

This is testified by the presence and the displayed value of an antimatter column on the R_ID row.<br /><br /><strong>Resolution</strong>:</p><p>To resolve this error message, you should perform the following methods, preferably in the given order:<br /></p><p><strong>Check for hardware issues</strong>: 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.<br /></p><p><strong>Restore from backup</strong>: Check if you have a clean and updated backup of the database. If yes, then you should restore the database with its backup.<br /></p><strong>Run DBCC CHECKDB</strong>: 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.<br /><br />However, if you still are not able to resolve this error by any which method then you should use a third-party <a rel="nofollow" href="http://www.mssqldatabaserecovery.com/">SQL recovery</a> software.

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.

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 <a href="http://www.mssqldatabaserecovery.com/">SQL Database Recovery</a> software to recover SQL database.<br /><br />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:<br /><br />“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.”<br /><br />Cause:<br />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.<br /><br />Resolution:<br />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.

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 <a href="http://www.mssqldatabaserecovery.com/">SQL Database Recovery</a> to be fixed. <br /><br />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. <br /><br />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. <br /><br />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. <br /><br />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. <br /><br />In case SQL Server database gets damaged due to incorrect updating of system tables, perform SQL Server Recovery by restoring the database from backup. <br /><br />If backup is unavailable, use <a href="http://www.mssqldatabaserecovery.com/">MS SQL Recovery</a> 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. <br /><br />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.Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-114924403928591005.post-15512810661201247262010-04-30T03:14:00.001-07:002010-04-30T03:14:42.140-07:00SQL Server Instance Does Not Start After Restoring Model System DatabaseMicrosoft 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 <a href="http://www.mssqldatabaserecovery.com/">SQL Database Recovery</a> to work around the problem if backup is not updated. <br /><br />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:<br /><br />“2003-04-18 09:37:38.85 spid5 Starting up database 'model'. <br />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.”<br /><br />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. <br /><br />Root of the problem<br /><br />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. <br /><br />Resolution<br /><br />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. <br /><br />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 <a href="http://www.mssqldatabaserecovery.com/">SQL Recovery</a> applications use advanced scanning algorithms to systematically scan whole database and extract all inaccessible objects from it. <br /><br />SQL Recovery is a powerful, yet easy to use and safe utility to ensure absolute recovery in all SQL Server database corruption scenarios.

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 <a href="http://www.mssqldatabaserecovery.com/">MS SQL Recovery</a>.<br /><br />Consider a scenario wherein you receive the following error message when you try to mount your SQL Server 2008 database.<br /><br />“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.”<br /><br />The error message states that the IAM page was found for the current index but it was not found for the next-page pointer.<br /><br />Cause:<br />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.<br /><br />Resolution:<br />To resolve the issue, you can perform the following measures:<br />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.<br />Replace the corrupted database with a clean backup.<br />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. <br /><br />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 <a href="http://www.mssqldatabaserecovery.com/">SQL Recovery</a> using fast yet sophisticated scanning algorithms without overwriting the damaged area. <br /><br />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.

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 <a href="http://www.mssqldatabaserecovery.com/">SQL Database Recovery</a> tool to repair SQL database.<br /><br />Consider a scenario wherein you are working on SQL Server 2008 system when you encounter the following error message:<br />“The index "%.*ls" on table "%.*ls" is disabled.”<br /><br />Cause:<br />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:<br />You have disabled the index manually by using ALTER INDEX.<br />The index is disabled as the database is corrupt.<br /><br />Resolution:<br />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:<br />1.First of all, enable the index by using either of the following methods:<br />ALTER INDEX statement with the REBUILD clause<br />CREATE INDEX with the DROP_EXISTING clause<br />DBCC DBREINDEX<br />2.Rerun the DBCC command.<br /><br />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 <a href="http://www.mssqldatabaserecovery.com/">SQL Recovery</a>.

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 <a href="http://www.mssqldatabaserecovery.com/">SQL Database Recovery</a> application.<br /><br />The above scenario can be explained with the help of the below error message:<br /><br />“Server: Msg 8905, Level 16, State 1, Line 1<br />Extent (1:886000) in database ID 37 is marked allocated in the GAM, but no SGAM or IAM has allocated it.<br />Server: Msg 8905, Level 16, State 1, Line 1<br />Extent (1:886112) in database ID 37 is marked allocated in the GAM, but no SGAM or IAM has allocated it. <br />…<br />Repairing this error requires other errors to be corrected first.<br />Repairing this error requires other errors to be corrected first.<br />Repairing this error requires other errors to be corrected first. <br />...”<br /><br />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.<br /><br />Cause:<br /><br />The above error message appears when the SQL Server 2000 database corruption is beyond the repair capabilities of DBCC CHECKDB command.<br /><br />Resolution:<br /><br />To resolve the above error message and to access the database records, the user needs to follow the below steps:<br /><br />Restore database from an updated, valid, and complete backup.<br />Use a third-party SQL Database Repair application in case no backup is available.

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 <a href="http://www.mssqldatabaserecovery.com/">MS SQL Recovery</a> applications to extract inaccessible data. <br /><br />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:<br /><br />“[Microsoft][ODBC SQL Server Driver][Named Pipes]ConnectionCheckForData (PeekNamedPipe()).<br />[Microsoft][ODBC SQL Server Driver][Named Pipes]Connection broken.”<br /><br />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. <br /><br />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. <br /><br />Cause<br /><br />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. <br /><br />Resolution<br /><br />Try out the below steps to sort out this problem:<br /><br />Obtain the latest service pack of Microsoft SQL Server. It helps you to prevent this problem from being occurred in future. <br />Drop all the automatically created statistics. <br />Restore SQL Server database from the most recent backup. <br />Repair and restore the damaged SQL Server database using powerful and advanced third-party applications, known as SQL Server Recovery software. <br /><br />The <a href="http://www.mssqldatabaserecovery.com/">SQL Server Recovery</a> 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 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 <a href="http://www.mssqldatabaserecovery.com/">SQL Recovery</a> tool.<br /><br />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:<br /><br />“Error: 0x80004005 E_FAIL<br />Minor Error: (25017)<br />Description: Unspecified Error”<br /><br />A Microsoft embedded Visual Basic (eVB) application that uses CompactDatabase method is not able to compact a corrupted SQL Server CE database. <br /><br />Cause:<br /><br />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.<br /><br />Resolution:<br /><br />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 <a href="http://www.mssqldatabaserecovery.com/">SQL Database Recovery</a> tool. Such tools employ fast yet sophisticated algorithms to scan damaged area for performing MS SQL recovery. <br /><br />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.Unknownnoreply@blogger.com0
