Problems with data guard setup.

OEL 7

Oracle database 19.12.

2 node RAC on the Primary and Standby.

We have a primary and a Physical standby.

We tried to do a switchover from the Primary to the Standy and that seemed to work, though I am not sure.

Then we tried to do another switchover so the config would be back to the original.

We're trying to make the original Primary be the current Primary and the original Standby be the current standby.

I'm trying to determine which database is the primary and which is the standby, and then proceed to make the original Primary the current Primary. And also make the original Standby be the current standby.
