Flashback standby database after upgrade fails
Dear Experts,
I plan to upgrade Oracle RAC Database 12c to 19 in Data Guard Environment.
Do I need to enable flashback on standby database as well before I start upgrading primary database?
if upgrade fails i have to flashback my primary database right?
I guess I need to flashback standby database as well to synchronize it with primary isn't it?
Or to flashback only primary database is enough and I don't need to flash back standby database as well?
Thank you all in advance.
Regards,
