Datafile string may have missed last block
Cause
Incremental backup may have missed last tail bitmap block of datafile to backup if all the below conditions are satisfied:
- It should be an incremental backup
- It should be a Locally Managed Tablespace
- Only one space tail bitmap block at last block of the datafile
- BLOCK CHANGE TRACKING and UNUSED BLOCK OPTIMIZAION should be used
- Last 2MB of datafile blocks should be modified and tracked by BLOCK CHANGE TRACKING
Action
Verify the tablespace of the datafile using EXECUTE DBMS_SPACE_ADMIN.TABLESPACE_VERIFY('<tablespace_name>'); If TABLESPACE_VERIFY reports any inconsistency, then rebuild bitmaps using EXECUTE DBMS_SPACE_ADMIN.TABLESPACE_REBUILD_BITMAPS('<tablespace_name>');
