Oracle Database Connectivity (OO4O)

I have a requirement to access an Oracle 8i DB (installed on NT server) using Active Server Page on a client machine (also NT server) which does not have an Oracle instance. Both servers are part of a TCP/IP network. What is the best way to accomplish this? Furthermore I downlaoded and installed OO4O81638.exe and OO4O81638full.exe from Oracle site and tried both, but non of them work.
