Oracle Grid Control database configuration save problem.

If you get following errors when trying to save configuration changes into database via Grid Control:
"Saving instance <INSTANCE_NAME> to repository and agent
https://<AGENT_NAME>:3872/emd/main/...-- exception caught when saving the <DB_NAME> to
agent https://<AGENT_NAME>:3872/emd/main/:
oracle.sysman.emSDK.emd.comm.OperationException: Skipping target {<DB_NAME>, rac_database}:
Missing properties - ClusterName ... finished."



This error is coming because Grid Control Agent targets.xml is missing ClusterName properties row.


To fix this problem:

Go into Agent servers and take backup of file: $AGENT_HOME/<nodename>/sysman/emd/targets.xml

And then add following row into file (for example after DBVersion row):
<Property NAME="ClusterName" VALUE="<CLUSTER_NAME>"/>

And in the end reload agent in Agent servers:
$AGENT_HOME/bin/emctl reload 

After these steps configuration should work normally.
