If you are really going to have 1500 simultaneous connections, you aren't going to be running Oracle on Windoze! Windoze servers are fine for *small* Oracle databases - with 1500 connections, an NT4 server would grind to a halt (from past experience).
If this is a large database (storage-wise), you really should be looking at running Oracle on Solaris (Sun) or OpenVMS (Compaq Alpha) servers. These will handle the storage, memory and processor loads much better! You *may* be able to get away with Linux on a very high-end system if the database itself is not huge, as it is more efficient than Windoze.
The main issue you will be facing with this many connections is memory usage. For Unix & OpenVMS, each individual connection (network server process) uses something like 4-5 Mb of RAM, so you would need a heap of memory to run Oracle in standard mode. It would be better (necessary here, I think!) to use MTS (multi-threaded server) where connections *share* network processes, so you can have significantly fewer of them. But you would probably still need a fast machine (SCSI disks, good processor etc) to handle the load from 1500 users!
