From your description it almost sounds like your standby wasn’t the standby you
thought it was. Like your TNS is pointing somewhere other than you thought.

I just cant get it to work!
Everything in the DGB setup looked fine. Even got it checked by a third
party.
But just as last time we tried we got a message from broker saying cannot
switchover and primary was still primary but when I looked
then we had two standbys. Nightmare!
My question is why did that happen?
The standby/primary pair operate fine manually but I really wanted to use
DGB.
My method to recover from this was
1. Connect to standby which should be primary. Alter database activate
standby database;
2. Rman into standby which should be standby – restore database;
3. Start recovery at end of restore.
