Your company wants to upgrade the current production database to the RAC environment. To perform testing before migrating to the RAC environment, you performed the workload capture on the production database to record the peak workload. You set up the test RAC database and want to replay the recorded workload on the test machine. Note the following steps that you may require to replay the database workload:
1) Preprocess the captured workload.
2) Restart the database in RESTRICTED mode.
3) Set up the Replay Clients.
4) Restore the test database to the point when the capture started.
5) Remap connections.
Arrange the steps required in the correct sequence to accomplish this task on the test machine.
