setting up ORACLE server

--
Hi all,

I've been asked by a friend of mine to help set up an
Oracle database on an intranet which will eventaully be
served to the internet from a web server.I have done
SQL programming before with ORACLE but have never set it up
from scratch before.

I was wondering if someone could give me some hints.

Here is what's required.

a:) Have Oracle running on NT to server to a network
b:) serving oracle through the web on a web server

I'd love some hints on how to set this up.

Thanx

David
