RE: oracle client on PC's

Jeffrey,
I've probably missed something, but if the application uses Merant's ODBC driver - which I believe is a wire-protocol driver, how come you need to install the client at all? Bruce Reardon

The application is a third-party application using Merant's ODBC driver.

How do people normally install the client. Do you do an install to every workstation???

There is a reason that Oracle doesn't support configurations like this. There is a fair amount of "chatter" between an application and the Oracle client DLL's. When this chatter starts flying over the network rather than merely going to a local DLL, you start to get performance problems.

How are your application(s) designed? It's probably possible to tweak an OCI application to make fewer OCI calls. If you're using ODBC, and have the budget, you could purchase one of the wire-protocol ODBC drivers.
