Re: Cloud Control Agent Question

Having just gone through something similar in order to get rid of the EM Hybrid Gateway I had configured, after dropping the Agent from the console (I used the web), I also needed to remove the Agent and home from the target host (all Linux for me):

export $AGENT_HOME=/u01/app/oem/product/emagent13.5/agent_13.5.0.0.0 perl $AGENT_HOME/sysman/install/AgentDeinstall.pl -agentHome $AGENT_HOME

It looks like this perl will detach/remove the Home properly, updating the Oracle Inventory. Seems that it could prevent future issues with target discovery, among other things. Obviously, run those as the Agent owner and substitute the correct path of your "agent_13.4.0.0.0" directory to test before using en masse.

Big fan of Ansible, but not here. Seems like it will cause more pain than it would save in this case.

GL!
