ORA-16651: requirements not met for enabling Fast-Start Failover

Cause : The attempt to enable Fast-Start Failover could not be completed because one or more requirements have not been met: - The Data Guard configuration must be in MaxAvailability protection mode. - The LogXptMode property for both the primary database and the Fast-Start Failover target standby database must be SYNC. - The primary database and the Fast-Start Failover target standby database must both have flashback enabled. - No valid target standby database was specified in the primary database's FastStartFailoverTarget property prior to the attempt to enable Fast-Start Failover, and more than one standby database exists in the Data Guard configuration.

Retry the attempted command after correcting the issue: - Set the Data Guard configuration to MaxAvailability protection mode. - Ensure that the LogXptMode property for both the primary database and the Fast-Start Failover target standby database are SYNC. - Ensure that both the primary database and the Fast-Start Failover target standby database have flashback enabled. - Set the primary database's FastStartFailoverTarget property to the db_unique_name value of the desired target standby database add the desired target standby database's FastStartFailoverTarget property to the db_unique_name value of the primary database.
