Cause: The attempt to enable fast-start failover could not becompleted because
one or more requirements were not met:
- The Data Guard configuration must be in either MaxAvailability or
MaxPerformance protection mode.
- The LogXptMode property for both the primary database and the fast-start
failover target standby database must be set to SYNC if the configuration
protection mode is set to MaxAvailability mode.
- The LogXptMode property for both the primary database and the fast-start
failover target standby database must be set to ASYNC if the configuration
protection mode is set to MaxPerformance mode.
- 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
FastStartFailoverTarget property prior to the attempt to enable fast-startfailover,
and more than one standby database exists in the Data Guard configuration.
