The customer in question runs their main applications on HP/UX, and does all their databasing on Oracle.
...so our contact wants to just chuck another 2K box on the network...
Why not a "religious conversion" of that 2K box to Linux! Linux
is much closer to HP/UX than Win2K. Also, you could use Postgresql as a great standin for Oracle. Later, you may decided you don't even need Oracle. Good Luck!
