Hi all,

I am using these parameters for dataguard configuration.

I am running in max-performace mode.can any body tell me whats the problem in failover from these pararameters.It is taking around 17-18 minutes in failover operation.

I can perform switchover within 2 and 1/2 minutes.

Change to max protection mode and you can bring down failover delay.
