3403 Error in SQL

Data files and Transaction log files are the two basic elements in Microsoft SQL Server. All the committed or uncommitted transactions are recorded by or handled by transaction log files. So whenever there is unexpected shutdown of SQL Server, this particular uncommitted log is added to transaction log files. Now if the user restarts the Server, all the SQL transaction log files are analyzed. If the transactions are not run successfully, then the changes performed in the queries related to that transaction persist.

But that’s not the case all the time. Sometimes, this automatic process of recovery does not successfully ends and thus leaving the database in the corrupted state only.

During the SQL Server database corruption, the user encounters the below error message:
Error 3403, Severity 22 during recovery initialization, page %ld was encountered. This page belongs to object %ld, not the log

Cause

At MS SQL Server crash, firstly automatic recovery is performed by the Server. Automatic recovery involves a complete scan of transaction logs up till the last page. Error 3403 occurs whenever a page is found in Syslogs but its page header object ID does not match with that of Syslogs. It leads to failure of automatic recovery. Reasons for this error 3403 to occur are

• Bad write or page allocation

• User updates the allocation page and SQL Server goes down prior to the writing of the transaction log page.

Solution

For solving this issue, firstly look for any backup you are having. If there exists a clean backup with you, then immediately drop the damaged or corrupted database and load it from the backup. But in case no availability of backups, then you are bound to take help of a professional efficient SQL recovery tool.
