Oracle Database Errors or Warnings from Error ORA-19651 to ORA-19660
ORA-19651: cannot apply offline-range record to datafile string: SCN mismatch
Cause: APPLYOFFLINERANGE cannot apply an offline-range record to a target datafile unless the datafile’s checkpoint SCN exactly matches the offline-clean SCN in the specified offline-range record.
Action: Specify an offline-range record whose offline-clean SCN matches the target datafile’s checkpoint.
ORA-19652: cannot apply offline-range record to datafile string: file is fuzzy
Cause: The target datafile for an APPLYOFFLINERANGE call is fuzzy.
Action: Specify a target datafile that is closed cleanly.
ORA-19653: cannot switch to older file incarnation
Cause: SWITCHTOCOPY was called with a datafile copy for a datafile that was dropped prior to the time this control file was backed up.
Action: Restore and mount an earlier control file. It is acceptable to use a control file that was backed up prior to the creation of the specified datafile.
ORA-19654: must use backup control file to switch file incarnations
Cause: This SWITCHTOCOPY operation is attempting to switch incarnations of a datafile, but the currently mounted control file is not a backup control file.
Action: Restore and mount a backup control file.
ORA-19655: cannot switch to incarnation with different RESETLOGS data
Cause: This SWITCHTOCOPY operation is attempting to switch to a datafile which comes from a different RESETLOGS version of the database.
Action: Either restore a backup control file that was taken from the same database version as the target datafile copy, or switch to a different datafile copy.
ORA-19656: cannot backup, copy, or delete online log string
Cause: The indicated log file is an active log. You can only backup, copy, or delete archived logs.
Action: The indicated log file cannot be processed – select another file.
ORA-19657: cannot inspect current datafile string
Cause: The file being inspected is already part of the currently mounted database.
Action: None – the file is already part of the database.
ORA-19658: cannot inspect string – file is from different RESETLOGS
Cause: The RESETLOGS data in the log file being inspected does not match that in the currently mounted control file.
Action: The indicated file cannot be processed – inspect another file.
ORA-19659: incremental restore would advance file string past RESETLOGS
Cause: This incremental backup cannot be applied to the specified datafile, because the datafile is from an earlier incarnation of the database, and its checkpoint would be advanced too far to be recoverable in the current incarnation of the database.
Action: This incremental cannot be applied to this datafile. If you wish to recover the file to the RESETLOGS SCN so that the database can be opened with the RESETLOGS option, then you must use redo-log recovery, not incremental restore, to continue recovering this file.
ORA-19660: some files in the backup set could not be verified
Cause: A restore conversation was made to verify all the files in a backup set, and the files which were printed in messages 19661 or 19662 could not be verified because corrupt blocks for those files were found in the backup set.
Action: Unless the damage to the backup set can be repaired, the indicated files cannot be restored from this backup set.
