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 compatibility 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.
