Not able to switchover to primary after switching to standby using Data Guard 10g

Hi,

I have two databases on 10g 10.2.0.4 located on HP-UX servers.

EXP (Primary) ----------------> EXPSTD(PHYSICAL Standby)

I had to test the validity of my standby database, that is why i have switched over to standby using Oracle Enterprise Edition. the switchover opened my standby as primary and my primary as standby.

After finished the validity check, i tried to perform the switchover again to go back to my previous configuration.

the operation didn't succeeded. checking the logs i noticed number of error but couldn't identify the reason for the problem. I have done the switchover (to old primary) on the 27-May-2017 at around 12PM.

Howdy, Stranger!
