Before a workload can be replayed, the application data state on the replay system should be logically equivalent to that of the capture system at the start time of workload capture. This minimizes replay divergence during replay. The method for restoring the database depends on the backup method that was used before capturing the workload. For example, if RMAN was used to back up the capture system, you can use RMAN DUPLICATE capabilities to create the test database. For more information, see "Prerequisites for Capturing a Database Workload".
After the database is created with the appropriate application data on the replay system, perform the system change you want to test, such as a database or operating system upgrade. The primary purpose of Database Replay is to test the effect of system changes on a captured workload. Therefore, the system changes you make should define the test you are conducting with the captured workload.
