How can I load the demo data to my WC 10.1 instance?

After installing my WC 10.1 instance (oracle backend), I have a request to add the demo data that comes with the install. How do I add this data to my instance? I tried re-running the installer, but now that I have the existing instance, the database portion of the installer doesn't come up. So is there some ant command that I can use to load the PTC demo data?
