Oracle wait event

Hi,

What is "wait for master scn" wait event? Can anyone explain this event with a scenario?

Thanks..

If you ahve RAC with 2 Nodes, synchronization will be done by using highest SCN. THis wait time is number of times foreground processes
waited for SCNs to be acknowledged from other instances in the cluster.

Hi Malay Biswal,

Thanks for your information.

Can you please explain what is "wait for scn from all nodes" with an example and which events in oracle database trigger SCN propagation?

Thanks..
