Delphi ISAPI.dll / DOA 4

[Dottie]

I am in the process of migrating a Delphi 2005 with DOA 4 Isapi.dll to run on a 64 bit Windows Server 2008 R2 box, connecting with Oracle 11g 64 bit client. First off is this do-able with DOA 4? Do I need an upgrade?
The problem I am running into first is that the ToracleSession.CheckConnection keeps returning ccError and doesn't seem to want to connect. This same code is running fine on Server 2000.
Thanks for any insight.

You will need to install a 32 Bit Oracle11g Client. Your isapi dll is a 32 Bit application, so it cannot interface with a 64 Bit Oracle Client.

The 32 Bit Oracle Client can communicate with a 64 Bit Server, even on the same machine if necessary. The 32 Bit client can coexist with a 64 Bit Oracle installation when installed in separate Oracle Home directories.
