Oracle : Ошибка ORA-00296

"maximum number of files (%s) exceeded for RECOVER DATAFILE LIST"
*Cause: The RECOVER DATAFILE LIST command specified more datafiles than
are allowed by the DB_FILES initialization parameter.
This error occurs when doing recovery with Recovery Manager, and
the instance has been started with a DB_FILES parameter specifying
fewer datafiles than recovery manager needs to recover to satisfy
the user's RECOVER command.
*Action: Re-start the instance with a higher value for DB_FILES.
