How do I specify a non-standard port for a remote Oracle connection in the "Create New Information Source" dialog? Does the Prism 'Oracle client' acknowledge TNSNAMES.ORA? If so, where/how does it search for TNSNAMES.ORA?

Never did receive a technical response to this from SiSense. I can tell you that, after playing around, dropping TNSNAMES.ORA into the "Prism Desktop" directory evidently allows the 'Prism Oracle Client' to leverage it (e.g., to specify a port).
