Oracle Database Errors or Warnings from Error ORA-01231 to ORA-01240

SQLServerF1

 

ORA-01231: cannot make read write – file string is offline
Cause: An attempt to make a tablespace read write found that one of its files is offline.
Action: Bring the file online and retry this command.
ORA-01232: cannot start online backup – file string is being made read-only
Cause: An attempt to start an online backup found that one of the files is in transition to read-only mode.
Action: Wait for the transition to complete and then retry the command, if this is an ALTER DATABASE BEGIN BACKUP command, or take the backup without any begin or end commands, if this is an ALTER TABLESPACE BEGIN BACKUP command.

ORA-01233: file string is read only – cannot recover using backup control file
Cause: An attempt to do media recovery using a backup control file found that one of the files is marked read only. Read only files do not normally need to be recovered, but recovery with a backup control file must recover all online files.
Action: If the file really is read only, take it offline before the recovery, and bring the read only tablespace online after the database is open. If the file does need recovery use a control file from the time the file was read-write. If the correct control file is not available, use CREATE CONTROLFILE to make one.
ORA-01234: cannot end backup of file string – file is in use or recovery
Cause: Attempted to end an online backup of file when the file is busy. Some operation such as recovery or rename may be active, or there may still be some instance that has the database open with this file online.
Action: If there is an instance with the database open then the backup can be ended there by using the ALTER TABLESPACE command. Otherwise wait for the completion of the other operation.
ORA-01235: END BACKUP failed for string file(s) and succeeded for string
Cause: One or more of the files in an end backup command failed. Some other files given in the same command may have succeeded.
Action: See the accompanying error messages for the reason the backups could not be ended. Any files not listed in the error messages were successful.

ORA-01236: Error string occurred during initialization of file header access
Cause: The indicated error occurred while doing initialization processing of file headers.
Action: The error indicated should be corrected. An attempt is made to recover from this error by using a slower access algorithm.
ORA-01237: cannot extend datafile string
Cause: An operating system error occurred during the resize.
Action: Fix the cause of the operating system error and retry the command.
ORA-01238: cannot shrink datafile string
Cause: An operating system error occurred during the resize.
Action: The error is ignored, operation continues normally.
ORA-01239: database must be in ARCHIVELOG mode to use external cache
Cause: An online file uses an external cache, but the database is in NOARCHIVELOG mode. Since an external cache may require media recovery this can not be allowed.
Action: Change database to be in ARCHIVELOG mode or do not use an external cache.
ORA-01240: too many data files to add in one command
Cause: The command specifies adding more data files than can be done in one command. It is necessary to fit all the file names into one log entry, but that would make the entry too large.
Action: If this is a CREATE TABLESPACE command, create with fewer files then add the other files later. If this is an ADD DATAFILE command, break it up into multiple commands.

Above are list of Oracle Database Errors or Warnings from Error ORA-01231 to ORA-01240 received while performing certain operation against Oracle Database or related products.
