Ethan - Is this a technical issue or a licensing issue?

 From the Oracle C++ Call Interface Programmer's Guide Release 2 (9.2):

Oracle C++ Call Interface (OCCI) is an application program interface (API) that provides C++ applications access to data in an Oracle database. OCCI enables C++ programmers to utilize the full range of Oracle database operations, including SQL statement processing and object manipulation.

The Net Services 9.0.1 client included with the Oracle 9i Developer Suite can still connect to Oracle 7.3.4 databases.

Note: although Oracle 7.3.4 is not supported on Windows 2000, it can be installed 1st (in default home using a Y2K compliant installer) then peacefully coexist with later Oracle versions.

Have Fun :)
