Thanks to all who replied!
I ended up completely removing PDMLink and ORACLE and re-installing
cleanly. The Windchill/PDMLink system is complicated enough without
wondering whether some lingering effect of a bad install is causing your
problems or whether they are native to the software stack. The responses
I got were all helpful in letting me gain a better understanding of the
complexity of the system. The advice to uninstall APHELION using
Add/Remove Progams was very timely.
Bottom Line: Pay attention to the details when installing PDMLink!
Thanks Again,
Ben
