Which is true concerning Database Replay in an Oracle Real Application Cluster (RAC) database?
A. Workload capture is per instance.
B. You only need to restart one instance to begin workload capture.
C. Specifically in RAC, you shut down all instances, restart them individually, and begin workload capture with the last instance started.
D. RAC does not support workload capture, but it does support workload replay.
E. None of the above.
Oprion A is incorrect because workload capture is for the databse,not for individual instance.B is incorrect because the correct procedure is to shut down all instances before you begin workload capture.Option C is incorrect;after the shutdown of all instances.start one instance to begin workload capture,and then start the remainging instances after capture begins,Workload capture and replay are supported in RAC,so D is incorrect.
