Oracle : Ошибка ORA-00327

"log %s of thread %s, physical size %s less than needed %s"
*Cause: A log file has shrunk in size. This is likely
to have been caused by operator or operating system error.
*Action: Restore the log file from backup. If backup is not available,
drop this log and re-create. If the database was shut down
cleanly, no further action should be required; otherwise
incomplete recovery may be required.
