ORA-38802 after switchover and switch back again

edited Feb 27, 2019 9:43AM in High Availability Data Guard, Sharding and Global Data Services (MOSC) 4 commentsAnswered

I have a Data Guard configuration with 11gR2 databases, primary on Windows Server 2012 and one standby on Linux 6.9 (Oracle database appliance). I configured the setup using Data Guard Broker and successfully switched from primary (Windows) to standby (LInux). There were no errors in either server's alert log or data guard log.

DGMGRL> switchover to odaclm_sby

Performing switchover NOW, please wait...

Operation requires a connection to instance "ODACLM" on database "odaclm_sby"

Connecting to instance "ODACLM"...

Connected.

New primary database "odaclm_sby" is opening...

Operation requires startup of instance "odaclm" on database "odaclm"

Starting instance "odaclm"...

ORACLE instance started.

Database mounted.

Howdy, Stranger!
