I am little bit surprised, that i am not able to get the status of standby database or you can say that standby database is not discovered in EM whereas primary database is discovered in the EM grid control
Grid control is Oracle 10g 10.2.0.5.0
Db version :- 11.1.0
I am getting the status of both the database from DGMGRL CLI
What i did is uninstall agent on the second machine whose db is not discovered and reinstall the agent back.
Now the problem is sorted out.
But now the problem again arises. I am able to get the status of standby database on OEM grid control. But when i try to perform change of data protection mode, i am getting error that Database standby is not discovered. This problem arise from em grid control only.
