Follow the instructions in Using the Software AG Installer, with the additional guidelines below.

If your Broker Monitor was configured to run as a UNIX daemon, you must un-register the daemon after you uninstall webMethods Broker. If you used the command line tool daemon.sh to register the daemon, use that tool again to un-register the daemon (see Register Daemons to Automatically Start and Shut Down Products on UNIX Systems for instructions). If you registered the daemon manually, revert your manual registration steps.
