ORA-16459
        recovery already beyond standby failover
        
        
        Cause
        Redo Apply stopped because it detected that it had proceeded beyond a standby failover operation.
        Action
        Determine the STANDBY_BECAME_PRIMARY_SCN by selecting it from V$DATABASE on the new primary database. Then, flashback the target database to this SCN and use RMAN to delete all archive logs at or beyond this SCN. Finally, fetch all terminal end-of-redo (EOR) logs corresponding to the failover operation from the new primary database and register all these logs at the target database. Restart Redo Apply.
