In database management technologies, a rollback is a process that returns the database to the some previous state. It is important for the integrity of database, because it means that database can be restored to a clean copy after some erroneous operations are carried out.
The rollbacks are critical for recovering from the database corruption and server crash; by rolling back the transactions which were active at the time of server crash, the database is returned to the consistent state.
In this way, you can see the importance of database rollback, but sometimes it could be dangerous for the database. An inappropriately handled rollback operation on the Exchange Server database could result into the database corruption.
The database corruption might lead the Exchange Server Information Store Service to terminate unexpectedly and shows some sort of access violation error messages. If the correct Exchange Server and Windows NT debug symbols are installed, the resulting log may show a stack dump like following:
FramePtr RetAddr Param1 Param2 Param3 Function Name
3f9ceb48 6feaf887 3f9ceb58 133f48b0 00000000 ESE!ErrNDSeek+0xb({...})
3f9ceb6c 6feb0010 10816f40 fffffed4 3f9cebf4 ESE!BTISeekSeparatorKey+0x48
......
After this problem, all of the data stored on the Exchange Server EDB file becomes inaccessible and you may face the nightmare of data loss.
Cause of the trouble
When the fundamental Exchange Server database engine attempts to rollback the conception of a LV (Long Value) tree on the table, opened with exclusive access, the database gets damaged. In such cases, the rollback is only partly successful.
Work around of the issue
The database corruption can be fixed only by repairing and restoring the database using appropriate tools. EDB repair is possible through the third party applications known as Exchange Server recovery software.
Third party or commercial applications are the easiest and quickest tools to repair and restore the damaged EDB file in each and every case of corruption. These software are fairly easy to use and don’t demand any sound and prior technical knowledge to carry out EDB recovery.
Stellar Phoenix Mailbox Exchange Recovery software is the best EDB recovery software till now.
