Answer / guest

Cause: An ALTER DATABASE PREPARE TO SWITCHOVER command was
issued, but the prepare activity did not complete.

Action: Verify that the standby was prepared properly. You
may cancel the prepare and perform an unprepared switchover
which requires a database link to complete. Or reissue the
prepare operation on the standby.
