Getting DOA to work installed on same box as 64-bit server?

[Clark]

I am working with version 4.0.7.1. I'm trying to get our 32-bit app talking to a 64-bit 11g2 Oracle database server installed on the same box (Windows 7 64-bit). I have tried 32-bit 11g2 database client and 32-bit 11g2 instant client and it seems to find the DLL it wants but it says no listener. (Oracle utilities can talk to my test database okay.) Is this overall configuration possible? If so, what are the overall basic steps for me to do? I'm not a novice but I am on unfamiliar ground here.

It should work fine. Perhaps you can enable Oracle Net tracing by setting "trace_level_client = USER" in the sqlnet.ora configuration file? The trace file may shed some light on this.
