What's the official method for uninstalling Reporter?
Reporter does not affect any system settings, or create/touch any special registry. It's basically the lay down of the files, and creation of the configuration inside the Reporter folders.
To remove Reporter from Unix, run:
rm -r /opt/netcool/reporter , where /opt/netcool/reporter is where Reporter has been installed.
For Windows use the uninstall option in the program menu to remove Reporter.
