Physical standby in maximum protection mode
I need your help in giving solution to my customer.My requirement is as below.
1> I've physical standby configured in maximum protection mode.
2> The database version is 11g.
3> My production server had some os/storage level failure.
4> The option with me is to activate the standby.
5> Would like to know if I do failover of my standby which will become current primary.Is there need to recreate the standby from scratch.
6> Is there any way to recover the former primary database which was unavialable and become available after a day so.
My concern is my database size is around 20TB and backing the database for standby recreation is not very easy task.
