ORA-00391: All threads must switch to new log format at the same time

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.
