| ERROR | 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 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-start failover, and more than one standby database exists in the Data Guard configuration. |
| ACTION | Retry the command after correcting the issue: - Set the Data Guard configuration to either MaxAvailability or MaxPerformance protection mode. - Ensure that the LogXptMode property for both the primary database and the fast-start failover target standby database are set to SYNC if the configuration protection mode is set to MaxAvailability. - Ensure that the LogXptMode property for both the primary database and the fast-start failover target standby database are set to ASYNC if the configuration protection mode is set to MaxPerformance. - Ensure that both the primary database and the fast-start failover target standby database have flashback enabled. - Set the primary database FastStartFailoverTarget property to the DB_UNIQUE_NAME value of the desired target standby database and the desired target standby database FastStartFailoverTarget property to the DB_UNIQUE_NAME value of the primary database. |
