How to uninstall Grid Control 11g agents

Shutdown the agent:

export AGENT_HOME=/u01/app/oracle/agent11g
$AGENT_HOME/bin/emctl stop agent

Delete the related targets from Enterprise Manager.

Run the deinstaller (silent mode):

$AGENT_HOME/oui/bin/runInstaller -invPtrLoc $AGENT_HOME/oraInst.loc -deinstall -silent "REMOVE_HOMES={$AGENT_HOME}" -removeallfiles

NOTE: I’ve included the ‘invPtrLoc’ flag above.  This is optional, but if you ever come across a server where multiple inventories are used, you’re going to have to supply this.

Once you see “Deinstall Successful”, you’re pretty much done.

You can if you prefer, perform the deinstall graphically using the following command:

$AGENT_HOME/oui/bin/runInstaller -invPtrLoc $AGENT_HOME/oraInst.loc

Check the oratab entry for agent11g and ensure it’s ORACLE_HOME directory have been removed:

grep agent11g /etc/oratab
ls $AGENT_HOME

Job done!
