Uninstall the PX agent through the GUI if present before removing the UX agent.

To uninstall the UX agent run the uninstall script as follows:

# cd /opt/IBM/ITM/bin

# ./itmcmd agent stop ux

# ./uninstall.sh ux aix526

Once its uninstalled, it leaves behind the directory structure, so you need to remove this

# cd /opt/IBM/ITM/

# pwd  <-- Run this to make damn sure you're in the right directory before running then rm cmd below..

# rm -r *
