Rod,
Unfortunately, I don't think you're going to find that documentation for GC3, either. Here's some documentation resources for you - however you'll find that they are all primarily technical docs:
OTM Main Site:
http://www.oracle.com/applications/s...ent/index.html
Brochures and Data Sheets:
http://www.oracle.com/applications/s...e-library.html
OTM v5.5 Technical Documentation:
http://www.oracle.com/technology/doc...tion/glog.html
OTM / GC3 v5.0 Technical Documentation:
http://www.oracle.com/technology/doc...on/glog50.html
I hope this helps!
