Troubleshoot "ORA-16556: observer version mismatch" in Dataguard Obsorver
Description:
I have connected Windows machine where Oracle Client is installed. To start observer I have connected the Primary database and checked database protection mode and configuration details ( See the screenshot). But when I tried to start observer, then failed with error 'ORA-16556'.
This should at least same as Primary and Standby database version or OBSERVER should support Primary and Standby database versions. Otherwise you will get ORA-16556 error.
Cause: This version of the observer was incompatible with the version of the specified Oracle database server to which the observer had been connected. This observer client cannot be used to observe the specified Oracle server. When I verified the database and client versions, I found following:
PRIMARY Oracle database version is 11.2.0.3.0(64bit) and Oracle Client version is 11.1.0.6.0(32bit). So client version is not compatible.
Action: Use a version of the observer that is compatible with the Oracle database server to be observed.
Cheers !!!
