DOA 4.1.1 with 64bit Oracle 11.2 client

[stantonw]

When I put my application on a 64bit Windows 2008 server using the 64bit Oracle 11.2 client I get the following error message when using TOracleSession.LogOn.
"Inialization error Could not load c:\oracle\ora11\bin\oci.dll"
I do not get the same error when using the 32bit client on a 64bit server OS. Unfortunately this server is the database server and the DBA understandably does not want to install the 32bit client.

Is there any way around this?

You will need to install a 32 Bit Oracle Client. Delphi/C++Builder generates 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.
