Hi,
I faced this problem suddenly when i was trying some indexes on a local dummy table(using 'sa' user id) on DB COSMOS. After working around indexes i saved the file and closed Query Analyzer. On relogging again with 'sa' user Id i faced the following problem "A connection was successfully established but then an error occured during the login process.(provider : Shared Memory Provider, error:0 - No process is on the other end of the pipe.) "
Then i logged in with Windows Authentication account. however i couldnt access DB COSMOS as it was put in Suspended Mode. On checking the event viewer i found below error
![]()
![]()
"SQL Server detected a logical consistency-based I/O error: incorrect checksum (expected: 0xb42e9a1f; actual: 0xb45a9f73). It occurred during a read of page (2:0) in database ID 7 at offset 0000000000000000 in file 'E:\COSMIC\COSMOS_log.ldf'. Additional messages in the SQL Server error log or system event log may provide more detail. This is a severe error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online."
Well how the above error can be repaired. There are no backups of this db. I cannot run DBCC CHECKDB command for COSMOS as the same has been suspended.
Please give me the solution to above problem.
Thanks
