Oracle Error Message
ORA-16659: failover operation in progress
Reason for the Error
A primary database that restarted contacted a standby database that is being failed over to.
Solution
Shut down 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 primary database after failover is complete allows it to be automatically reinstated as a standby database to the new primary database.
