I checked on Oracle's Metalink forums and unfortunately, the basic answer is no. They are currently hedging their bets and saying that they will be certifying first on Oracle 9i and that they can't guarantee 8i and it's applications - "yet".

I did notice in one of the forums that some people did have success with it and some of 8i's applications such as developer, however these were in tech discussions for problem resolution. So take it with a grain of salt.
I'd probably wait if you can orcheck into the feasibility of and upgrade to 9i.

If you have a tech support contract check at
http://metalink.oracle.com - you'll have to give them your CSI number.
