Silent uninstallation of 11.1 Agent

If you have decided not to have oracle agent home any more then you can use below sample script to uninstall in silent mode. Before you start uninstallation you must stop the agent.

Stop the Agent and ensure you have exported proper home of AGENT or run the command from $AGENT_HOME

$emctl stop agent

After the agent is down and now we are very much fine to remove the AGENT_HOME, If you are using Unix/Linux then binary will be runInstaller and in case of windows the binary file should be setup.exe

-bash-3.2$ ./runInstaller -silent -deinstall "REMOVE_HOMES={/u01/app/oracle/agent11g}" -removeallfiles
