Using Grid Control 11g.
I have a four node cluster and one morning node 3 and 4 were showing 'Agent Unreachable'.
So I go to each node and I stop each agent and restart each agent
emctl stop agent
emctl start agent
.. and I get 'Agent is Running but Not Ready' after the restart command.
I've been to MetaLink and the docs but no joy.
If someone could point me to a troubleshooting guide that would be great.
Of couse - suggestions are always welcome,
If you have not looked at files in the <Agent Home>/sysman/log directory, especially emagent.trc and emagent.nohup, for clues, then do so.
Also, if this agent monitors a high number of targets, it will take longer to become ready. In this case, you may want to look at MOS note 464851.1 for information on tuning the agent.
