Oracle : Ошибка ORA-00391

"All threads must switch to new log format at the same time"
*Cause: An attempt to switch the current log of a single thread is not
allowed because the compatiblity requirements force a new log
format version number. When changing log formats, all threads
must switch to the new format at the same time.
*Action: Open the database to cause the coordinated log switch. If that
is not possible then return to the same software version and
compatibility setting last used to open the database.
