Oracle : Ошибка ORA-01234

"cannot end backup of file %s - 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.
