Whenever we install EM agent, it will use default port at time of installation on target host. If we need to modify the port then we can follow below steps to change the port number.
Stop the EM Agent
$ $AGENT_HOME/bin/emctl stop agent
Modify the $AGENT_HOME/sysman/config/emd.properties file in the EM Agent home directory:
For example:
EMD_URL=http://example.com:3872/emd/main
Modify the <port number> in the EMD_URL property so the EM Agent uses a new unused port on the target host.
EMD_URL=http://example.com:3883/emd/main
Start the EM Agent.
$ $AGENT_HOME/bin/emctl start agent
Check the EM status
Stop the EM Agent
$ $AGENT_HOME/bin/emctl stop agent
Modify the $AGENT_HOME/sysman/config/emd.properties file in the EM Agent home directory:
