An internal error has occurred at the agent: “java.lang.IllegalStateException: getAgentSubstitutionMap(“cluster.ClusterName”) == null”

While testing a named credential in OEM 13c by following command with errors:

Here “CLU-RACTEST” is the GI cluster name.

$emcli test_named_credential -cred_names="SEC_RACTEST" -target_name="CLU-RACTEST" -target_type="cluster"

An internal error has occurred at the agent: "java.lang.IllegalStateException: getAgentSubstitutionMap("cluster.CLU-RACTEST") == null". Check the agent's error logs for details.

Run “emctl config agent listtargets”, it shows there is no ‘cluster’ target type listed for any of the monitoring agents.

The <AGENT_INST>/sysman/log/gcagent.log showed the below errors.

SOLUTION

From the OEM Console, go to Cluster homepage -> Target Setup -> Monitoring Configuration.
Click on the Update button (no need to make any other changes).

This will push the cluster target details to the agent side.

Then run “emcli test_named_credential” successfully.

$emcli test_named_credential -cred_names="SEC_RACTEST" -target_name="CLU-RACTEST" -target_type="cluster"

Credentials "SEC_RACTEST:SYSMAN" tested successfully
