We have 3 database on Primary server and 3 standby database configured accordingly. It is physical standby dataguard setup.
Windows: Version 184.108.40.206.0 - 64bit Production.
DGMGRL configuration created separately for each database and performed the switchover testing and everything working fine.
Observer configured and did the failover test. The standby become primary and it is up and running.
Now the problem ,
The former primary is not coming up and auto reinstate failed. Manually started and mount the database, then the observer trying to do the auto reinstate, but it fails. Manual auto reinstate also failing. Autoreinstate parameter set as TRUE.
