ORA-16829 fast-start failover configuration is lagging

Cause: The fast-start failover target standby database was not within the lag limit specified by the FastStartFailoverLagLimit configuration property. As a result, a fast-start failover could not happen in the event of a primary database failure.

Action: Ensure that the fast-start failover target standby database is running and applying redo data and that the primary database is successfully trasmitting redo data. If this condition persists consider raising the value of the FastStartFailoverLagLimit configuration property.

  
 Lag Limit ile ilgili bir sorun olduğunu göstermekte, yapılacak işlem, diğer hususlarda bir sorun görümüyorsa, LagLimiti biraz artırmak olacaktır :

DGMGRL -> edit configuration set property FastStartFailoverLagLimit =45;
