- Corruption errors are reported against one of more ASE tables and/or indexes in the following scenarios:
- user database recovery during ASE boot/start-up
- SID database recovery on systems running SAP applications
- load transaction
- load database
- The errors are related to table or index page-level corruption.
Some examples of the errors are: Error 605, Error 692, Error 691, Error 631, Error 625, Error 644, Error 2503, Error 2628, Error 12546, Error 3474, Error 12313, Error 632.
- The errors prevent the ASE database from being recovered successfully and/or prevent transaction log records from being applied during recovery.
Due to this, the entire database is rendered offline and marked "suspect" even though only one or a few corrupt objects might exist.
- The safest and advisable way to correct this situation is by restoring the database from a latest, clean backup. On SAP systems, an import/export method using file-system backups can also be used.
- Many a time, restoring an older, clean copy of the database or a database rebuild, is not feasible - and they may lead to a significant loss of data and transactional activity.
- If there is no clean, recent database backup available, or an SAP import/export is not possible: use "Recovery Fault Isolation" (RFI) to bypass the offending ASE corruption errors and corresponding corrupt pages - and bring the database online.
- With RFI, users can still access the database in it's current transactional and operational state.
- You can plan to fix the affected object(s) once the database is online; by rebuilding the affected object(s) -- via t-code SE14 on SAP systems or via select into / bcp
- The RFI procedure does not apply to system databases or system tables belonging to user & system databases.
- Almost all corruption-related ASE errors are handled by RFI including but not limited to: 605, 692, 695, 644, 3474, 1125, 1141, 1134, 1152, 1131, 1142, 1143, 1135, 6902, 3301, 3311, 3312, 12300, 12308, 12312, 12313
