ORA-16659: failoveroperation in progress
Cause: A primary database that restarted contacted a standbydatabase that is
being failed over to.
Action: Shutdown the primary database and wait for failover to complete on the
standby database. Once failover is complete, restart the old primary database.If
the failover occurred due to fast-start failover, restarting the primarydatabase
after failover is complete allows it to be automatically reinstated as astandby
database to the new primary database.
