Oracle 7 and 9

Finally finished dealing with Oracle 7.3.4, for now. Gee it's a pain to
use. It's been both an interesting learning experience and a nightmare
to try and setup the few databases for development.

Now I'm onto setting up a few 9i databases for testing. The most
interesting part was trying to get the listener on the server to listen
for both the version 7 and version 9 database. I eventually realised
that I just have to stop the v7 listener, configure the 9i listener,
then only start the 9i listener.

Now I just have to configure the accounts, copy the data, blah, blah,
blah. Time consuming, but not difficult.
