Part I, II and III.
For the time being I am throwing in the towel. I managed to patch my 10.2.0.1 version up to 10.2.0.3 thinking that might help, but it did not.
I'm still leaning to something on the 220.127.116.11 side, the only reason being is that in the trace file generated by the 10g instance, I see a "Alter9iSource" line in there...but there is nothing in the alert log on the 9i instance.
So I'm packing it up for a little while, hopefully the time away will do me some good and help me regain focus.
I did find a great example of the manual setup by Lewis Cunningham; that may be the route in the future, just a bit more work to maintain.
