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.
