    As far as I know, the application just runs queries on our     supplier's database and makes the results available in     a particular format on a TCP port. It has fairly little dancing     baloney, at least by Windows standards.

   I already set ORACLE_HOME to be the Instant Client install directory.

   I'm not at all familiar with Windows, and could not begin to guess what

   registry entries we might need.

    I presume that the message comes from an Oracle stub that was     compiled into the application. I seriously doubt the programmer     put the message in.

    By "windows application", I means some software that was written     to run under Windows (as opposed to, say, Linux.) Very specialpurpose,

    on the order of 10 copies in existence, I would guess. The details are

    not relevant, but it's not something that would be bought and sold.

    It was the "vendor" that told us to install Oracle Client. They     may not even know what Instant Client is. Received on Tue Nov 04 2008 - 08:06:07 CST
