Resolving Agent12c Unreachable

In OEM if you see the your targets have a status of unreachable here are a few steps you can take to try and resolve the issue.

  

$cd $AGENT_HOME/bin/

$./emctl clearstate agent

$./emctl stop agent

$./emctl clearstate agent

If the agent will not stop you can search for the OS process and issue a kill -9

$ps -ef |grep agent12c/core/12.1.0.1.0/jdk

$kill -9 <pid>

$./emctl clearstate agent

$./emctl start agent

$./emctl upload agent

If the upload fails issue the upload command again

$./emctl upload agent

In OEM you should now see that all targets are back online

If the above steps do not work you can doing the following

$cd $AGENT_HOME/bin/

$./emctl clearstate agent

$./emctl stop agent

$./emctl clearstate agent

$cd AGENT_INST/sysman/log

$rm -rf *.*

$rm -rf state upload

$cd $AGENT_HOME/bin/

$./emctl clearstate agent

$./emctl start agent

$./emctl clearstate agent

$./emctl status agent
