In SQL Server 2008, the Auditing feature has been introduced that allow you to track user and system activity for the enterprise customers. This feature provides the option to detect any unauthorized access attempts, if any, to the SQL Server database. Also, it facilitates a rich and powerful tracking capability to recognize any sensitive configuration changes to the database by the administrators. However, at times the auditing process can fail thereby making the database get corrupt. You should use appropriate corrective measures to rectify the problem. If you are not able to address the situation, then you should use a third-party SQL recovery tool software to recover SQL database.

Consider a scenario wherein you encounter the following error message while auditing a database table in SQL Server 2008.

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

Cause:

The root cause of this error message is that auditing has failed because of header corruption in the P_ID page. Because of this problem, the database table has corrupted.

Resolution:

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

Check for hardware issues: You should check the hardware components and event logs to confirm whether the error has occurred because of any faulty hardware component. You should also swap the hardware components to narrow down on the erroneous issue. Also, you can also consider reformatting the hard disks and reinstalling the operating system. However, before doing this you should take a thorough backup of your valuable data.

Restore from backup: If the error is not because of any hardware malfunctioning, then you should check the state of the backup. If the backup is clean and updated, then you should restore the database from the backup.

However, if the aforementioned methods are not resolve the situation then you should use a third-party SQL Server recovery software to recover SQL database. Such tools are read-only in nature that do not overwrite the original data while scanning the corrupted SQL database.
