ORA-16649: database will open after Data Guard broker has evaluated Fast-Start Failover status

Cause: The database is being opened while Fast-Start failover is enabled. The message indicates that the Data Guard broker will first determine if conditions are suitable for opening; that is, a Fast-Start failover did not occur while the database was unavailable.

Action: No action is normally required. The Data Guard broker will continue opening the database after determining a Fast-Start failover did not occur. If there is a chance that a Fast-Start Failover did occur, the database will remain in the mounted state and will not open. In this case, check the target standby to see if a role transition took place.
