Oracle Database Errors or Warnings from Error ORA-01546 to ORA-01552
ORA-01546: tablespace contains active rollback segment ‘string’
Cause: Tried to make a tablespace that contains active rollback segment(s) offline or read-only
Action: Shutdown instances that use the active rollback segments in the tablespace and then make the tablespace offline or read-only
ORA-01547: warning: RECOVER succeeded but OPEN RESETLOGS would get error below
Cause: Media recovery with one of the incomplete recovery options ended without error. However, if the ALTER DATABASE OPEN RESETLOGS command were attempted now, it would fail with the specified error. The most likely cause of this error is forgetting to restore one or more datafiles from a sufficiently old backup before executing the incomplete recovery.
Action: Rerun the incomplete media recovery using different datafile backups, a different control file, or different stop criteria.
ORA-01548: active rollback segment ‘string’ found, terminate dropping tablespace
Cause: Tried to drop a tablespace that contains active rollback segment(s)
Action: Shutdown instances that use the active rollback segments in the tablespace and then drop the tablespace
ORA-01549: tablespace not empty, use INCLUDING CONTENTS option
Cause: Tried to drop a non-empty tablespace
Action: To drop all the objects in the tablespace, use the INCLUDING CONTENTS option
ORA-01550: cannot drop system tablespace
Cause: Tried to drop system tablespace
ORA-01551: extended rollback segment, pinned blocks released
Cause: Doing recursive extent of rollback segment, trapped internally by the system
ORA-01552: cannot use system rollback segment for non-system tablespace ‘string’
Cause: Tried to use the system rollback segment for operations involving non-system tablespace. If this is a clone database then this will happen when attempting any data modification outside of the system tablespace. Only the system rollback segment can be online in a clone database.
Action: Create one or more private/public segment(s), shutdown and then startup again. May need to modify the INIT.ORA parameter rollback_segments to acquire private rollback segment. If this is a clone database being used for tablspace point in time recovery then this operation is not allowed. If the non-system tablespace has AUTO segment space management, then create an undo tablespace.
Above are list of Oracle Database Errors or Warnings from Error ORA-01546 to ORA-01552 received while performing certain operation against Oracle Database or related products.
