3. Checked Flashback Database from Primary Database (PRD)
Observer to be able to automatically reinstate the former primary database as a standby database after our failover tests, so before each test, make sure that Flashback Database has at least 30 minutes of history. Do this prior to every failover test. If Flashback Database history is insufficient, the observer will not be able to reinstate and you will have to manually reinstate from backup or by primary duplication.

6. Execute "Startup Mount" in Old Primary Database (PRD) to initiate reinstate process
Initiate reinstatement by mounting the old primary database (PRD). Note that the database will not open at this point. A database in the primary role will not open until it has verified with the observer that it is still the primary. If the observer finds that the database is no longer the primary, it will attempt to reinstate it as the failover target physical standby database
