OEM agent process among top CPU utilization

Issue: 

Noticed that OEM 13c agent is continuously among the top CPU consuming process.

Observations:

There is a Java Process always appearing on the top CPU consuming processes.

 

Memory allocated for the OEM agent process was set by default to 141M heapsize.

Because of this, we saw out of memory errors in the heapdump of the agent process.

Fix:

1) Stop the Agent ($AGENT_HOME/bin/emctl stop agent)

2) Take backup and edit the emd.properties file (AGENT_INST/sysman/config/emd.properties)

default

agentJavaDefines=-Xmx141M -XX:MaxPermSize=96M

new

agentJavaDefines=-Xmx512M -XX:MaxPermSize=96M

3) Start the agent

$AGENT_HOME/bin/emctl start agent

After this we never see the OEM agent as the top CPU consuming process.
