Agent Unreachable
- Is the agent running?
From SQL*Plus:
select username,program from v$session where LOWER (program) like 'emagent%';
If no rows selected, the agent is not running. or
From Unix: . oraenv agent11g (how to see [[which databases are running on the machine]]) emctl status agent ps -ef|grep [a]gent
There should be a handful. If only a few, kill them and restart the agent.
emctl start agent
Check the agent log in $ORACLE_HOME/sysman/log
Backend WLS or EM application seems to be down
To list targets known to an agent:
emctl config agent listtargets
It looks at the file $AGENT_HOME/sysman/emd/targets.xml
Manually add targets by editing this file and running:
emctl config agent addtargets $AGENT_HOME/sysman/emd/targets.xml
Check state and upload directories under $AGENT_HOME/sysman/emd for .err files
