Incomplete synchronization of mirror database and database corruption in SQL Server 2005

Microsoft has customized its SQL Server over the recent versions to provide administrative ease and a range of new features for improving productivity, efficiency, and availability. It has introduced database mirroring to achieve failover clustering at the database level. Moreover, you can take database snapshots to get instant reports of your SQL database. It allows you to perform safe transactions by maintaining the data consistency during the whole transaction. Inspite of all these benefits, SQL Server users frequently encounter database corruption. This database corruption may be induced due to a number of reasons, such as virus infection, operating system bugs, application errors, etc. As a consequence, all precious database components become inaccessible. To overcome this problem, you need to go for SQL server recovery through a reliable third-party tool.    

For instance, you may come across the following error message while using an SQL Server 2005 database:

“Synchronization of the mirror database, '%.*ls', was interrupted, leaving the database in an inconsistent state. The ALTER DATABASE command failed. Ensure that the mirror database is back up and online, and then reconnect the mirror server instance and allow the mirror database to finish synchronizing.”

Cause:

The above error occurred due to the failure of “ALTER DATABASE database_name SET PARTNER OFF” statement. Due to failure of this command, the synchronization process of the mirror database was interrupted and thus, the database became inconsistent.

This would prevent you from accessing the database tables and other objects in the database. You can use an updated backup to restore the database. However, if the backup is unavailable, follow the below given resolution steps. 

Resolution:

Try the following steps to resolve the issue:

• Try to synchronize the mirror database by establishing connection with the mirror server and the principal server.
• You can also try dropping the mirror database.
• When you drop the mirror database, use backups to create a new mirror database.

Note: If you don't have backup of mirrored database then don't drop it.

If you still face problems in accessing the database objects, take help of a proficient SQL database recovery tool. These third-party software perform a close recovery of SQL databases to restore all damaged or inaccessible objects, such as tables, views, indexes, constraints, queries, user-defined functions, etc. Furthermore, they support the latest SQL Server versions, including MS SQL Server 2008, 2005, 2000, and 7.0.

MDF database recovery utility to deal with Table error Extent P_ID range of this database

While working on your SQL Server database, sometimes the database tables become completely inaccessible following any corruption or damage to the database. The reason behind the corruption can be virus attack, file system corruption, application malfunction, simultaneous access by the number of users beyond the upper load limit etc. In any of these situations, the database flashes some sort of error message, which points toward a possible problem with the database. You need to resolve the error to regain access to the database tables. However, if you failed to resolve the issue, there are third-party SQL database recovery tools available, which can help you recover the database back.

The error message that you may have encountered can be read as below:

“Table error: Extent P_ID object ID O_ID, index ID I_ID is beyond the range of this database.”

After encountering the error message, you can not be able to access any record from the SQL database and receive the same error, each time you try to access any table.

Causes: The above error tells that the size of the pageinfile of the SQL database has been greater than the physical size of the filenum. Here, the P_ID is the PageID of the filenum:pageinfile form. This is the reason behind the error and may have been occurred due to a possible metadata structure corruption.

Resolution: In order to resolve the problem, you have to run the DBCC CHECKDB command with appropriate clause. This will repair the corrupt database.

If you failed to resolve the problem, you have to look for your backup server for any available valid backup. But, if you have not taken any backup recently or there occurs any error while resolving the problem, you are left with a single choice of running any mdf database recovery software.

These mdf file recovery utilities are designed with powerful algorithms to repair the database and recover various objects, including the tables, views, forms, containers etc with ease. These SQL recovery applications are completely read-only in nature and do not modify the database by any degree. Moreover, with the highly interactive graphical user interface, any user can use the software and retrieve his data without even any further assistance.

Rectifying Error 5228 in SQL Server 2008

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 MDF repair 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.

Rectifying Error 2579 in SQL Server 2000

The most basic unit of storage in an MS SQL Server database is a page, which accounts for 8 KB of size. And 8 such pages consist an extent thereby making 16 extents in 1 MB. An extent is used to allocate spaces for tables and indexes. The well-being of the database structure is absolutely essential for the database. However, at times problem arises in the structure of the database because of various reasons such as virus infection, power surges, human error, hardware failure, etc. In such cases, you should use appropriate measures to rectify the situation. However, if you are unable to do so then you should use a third-party SQL server recovery software to recover SQL database.

Consider a scenario wherein you encounter the following error message while working on an MS SQL Server 2000 database table.

“Table error: Extent P_ID object ID O_ID, index ID I_ID is beyond the range of this database.”

Cause:

The cause of this error message is that an extent has been allocated in an Index Allocation Map (IAM) page for the referenced index ID. In the error message, P_ID is the ID of the corrupted page in the table. The pageinfile of the extent is greater than the expected size of the file specified in the database, which has caused the error.

Resolution:

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

Look for hardware issues: Run hardware diagnostics to resolve any issues. Also, check the error logs to check whether the issue has occurred because of any faulty hardware. You can also swap the hardware components to zero in on the problem. You can also consider switching to a new hardware system altogether.

Restore from backup: Restore the database from its backup if it is updated and clean.

Run DBCC CHECKDB: Finally, you can run the DBCC CHECKDB command, first, without any repair clause to know the corruption level. Then, run the command again with the suggested repair clause. However, you should refrain from using this method if you are not sure about the aftereffects of using the repair clause on the database.

However, if you are unable to address the situation even after using the mentioned methods then you should use a third-party SQL Server recovery software to recover SQL database. These read-only tools are able to perform SQL database recovery using fast yet sophisticated scanning algorithms without damaging the original data.
