9.5 Refresh Considerations, or Lifecycle of Exadata Snapshots

Refresh cycles can influence how you use and create Exadata Snapshots.

The test master must remain in either READONLY state (if open) or closed while it has Exadata Snapshots associated with it. If the test master needs to be refreshed, all Exadata Snapshots dependent on the test master must be dropped and re-created.

If different groups of Exadata Snapshot users have different refresh cycle requirements, you may need to maintain multiple test masters. The following figure shows three test masters, each with its own refresh schedule.
