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

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

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

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

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

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

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
