Oracle Enterprise Manager Management Agent is not starting

Question

Many thanks in advance.

Database Version: Oracle DB 11g Enterprise Edition Release 11.2.0.1.0

The Operating System is AIX:

Please look into the points below:

1. Agent version mismatch. (I am just guessing if these are an issue)

$ emctl getversion agent Oracle Enterprise Manager 11g Database Control Release 11.2.0.1.0 Copyright (c) 1996, 2009 Oracle Corporation. All rights reserved. Enterprise Manager 10g Agent Version 10.2.0.4.0

As we can see above the agent version is 10.2.0.4.0

However, in the emd.properties the Agent Version is mentioned as below:

#@description=Agent Version agentVersion=10.2.0.0.0

So, agent version mismatch can be an issue. But before that I have another issue. Please look at point no. 2 below.

2. Though, I can check the status of the agent. I am not being able to start the agent at all. How is that possible? Please check the output of the commands below.

$ emctl status agent Oracle Enterprise Manager 11g Database Control Release 11.2.0.1.0 Copyright (c) 1996, 2009 Oracle Corporation. All rights reserved.

3. When I checked the status of the listener:

The listener is started with default configurations. ie, no listener.ora file in $ORACLE_HOME/network/admin

And, it also DON'T SHOW the below service. Is it an issue for the Management Agent to start?

Service "ABCDXDB" has 1 instance(s). Instance "ABCD", status READY, has 1 handler(s) for this service...

Below is the output of lsnrctl status:
