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.
