RE: Oracle restart and Physical Data Guard

In the configurations that allow FSFO, when the old primary starts back up it will do a check with the Observer and it's standby pair (when mounted) to make sure if it is still the primary database. If it cannot confirm, it will not open and will stay in mounted mode. In your example, during that check it should determine that it is no longer the primary database in that configuration and will not start up. If configured correctly, the observer should then also tell it to reinstate itself as the standby

That is at least my understanding of the process. We are running FSFO, but not with Oracle restart.

Thanks,
Mike

Subject: Oracle restart and Physical Data Guard

Hello,
I wonder if there are any issues in using Oracle 11gR2 restart and DG FSFO Observer together. Oracle restart is used for automatic restart of resources (database instance, listeners, etc..) after server reboot for example, if the Observer failover to the physical standby and open it and at the same time , oracle restart open the primary then split brain. Any experience ?

Thank you
