I'm pretty sure you are correct, support for Oracle 7.x has officially been dropped by pretty much everyone, including Oracle.

That doesn't necessarily mean it can't be made to work, however.
First off, what version of Oracle 7 are you running, exactly? The 'normal' ODBC drivers are supposed to work for Oracle 7.3.4 and higher, however the
wire drivers do require version 8 or higher, from what I remember. Which one did you try? How do they 'not work'?
If your server is already pulling data from Oracle 8i and Oracle 9i database, have you just tried connecting back to your 7 database with one of the OCI stages - like OCI8? I'd at least give that a shot and see what happens. I'd also be curious what client you have as your default client on your server - are you using the 8i or the 9i client right now?
