Oracle Database Errors or Warnings from Error ORA-01241 to ORA-01250

SQLServerF1

 

ORA-01241: an external cache has died
Cause: The external cache may have been restarted.
Action: Take the file mentioned in the error stack offline, perform media recovery, bring the file online, and retry the attempted operation. You may also restart all instances to make sure they access all data files through consistent external caches.
ORA-01242: data file suffered media failure: database in NOARCHIVELOG mode
Cause: The database is in NOARCHIVELOG mode and a database file was detected as inaccessible due to media failure.
Action: Restore accessibility to the file mentioned in the error stack and restart the instance.
ORA-01243: system tablespace file suffered media failure
Cause: A system tablespace file was detected as inaccessible due to media failure.
Action: Restore accessibility to the file mentioned in the error stack and restart the instance.

ORA-01244: unnamed datafile(s) added to control file by media recovery
Cause: Media recovery with a backup control file or a control file that was rebuilt, encountered the creation of a datafile that was not in the control file. An entry has been added to the control file for the new datafiles, but with the file name UNNAMEDnnnn, where nnnn is the file number. Attached errors describe the file names that were originally used to create the files.
Action: Rename the files to valid file names and resume recovery. If necessary the command ALTER DATABASE CREATE DATAFILE may be used to create a file suitable for recovery and do the rename. If the file is not going to be recovered then take it offline with the FOR DROP option.
ORA-01245: offline file string will be lost if RESETLOGS is done
Cause: Attempting to do an OPEN RESETLOGS with a file that will be lost because it is offline. The file was not taken offline with the FOR DROP option.
Action: Either bring the file online and recover it, or take it offline with the FOR DROP option.
ORA-01246: recovering files through TSPITR of tablespace string
Cause: The files named in the accompanying errors are backups that were made before a tablespace point in time recovery of this tablespace. They cannot be recovered to a time after the point in time recovery.
Action: Restore more recent backups and recover them.

ORA-01247: database recovery through TSPITR of tablespace string
Cause: Recovery of the whole database encountered redo indicating there was a point in time recovery of the tablespace. The new version of the files in the tablespace should be included in the recovery, but that was not done.
Action: If the tablespace should not be recovered, take its file offline for drop. If it should be recovered, then restore or rename as needed and restart the recovery.
ORA-01248: file string was created in the future of incomplete recovery
Cause: Attempting to do a RESETLOGS open with a file entry in the control file that was originally created after the UNTIL time of the incomplete recovery. Allowing such an entry may hide the version of the file that is needed at this time. The file number may be in use for a different file which would be lost if the RESETLOGS was allowed.
Action: If more recovery is desired then apply redo until the creation time of the file is reached. If the file is not wanted and the same file number is not in use at the stop time of the recovery, then the file can be taken offline with the FOR DROP option. Otherwise a different control file is needed to allow the RESETLOGS. Another backup can be restored and recovered, or a control file can be created via CREATE CONTROLFILE.
ORA-01249: archiving not allowed in a clone database
Cause: Attempting to archive an online redo log or enable archiving for a clone database.
Action: Do not attempt to archive from a clone. The archive log destination could easily be the same as the primary database destroying its archived logs. If archiving is needed then recreate database as not a clone.
ORA-01250: Error string occurred during termination of file header access
Cause: The indicated error occurred while terminating the processing of file headers. The error was other than a write error.
Action: The indicated error should be corrected.
