Oracle : Ошибка ORA-00259

"log %s of open instance %s (thread %s) is the current log, cannot archive"
*Cause: An attempt was made to archive the current log of an open
thread. This is not allowed because the redo log file may
still be in use for the generation of redo entries.
*Action: Force a log switch in the instance where the thread is open.
If no instances are open, open the database so that instance
recovery can recover the thread.
