Failed to start HTTP listener.

Solutions

1. Go to $AGENT_HOME/sysman/config

2. Modify the emd.properties file as follows:
Change the parameter

AgentListenOnAllNICs=TRUE
to
AgentListenOnAllNICs=FALSE

Note: This will cause the Agent to only listen on the specific NIC as stated in the EMD_URL parameter in the emd.properties configuration file.

2. Startup the Agent
/bin/emctl start agent

[oracle@egrouptest agent10g]$ emctl start agent
