Upgrade Tuner is part of the Siebel Server and runs only under Microsoft Windows. Upgrade Tuner does not run on UNIX. To tune UNIX production upgrade files, you must copy them to a Windows computer, tune them, and move them back to the UNIX computer. Scripts are provided to move the files.

If you are a UNIX customer and do not have a Siebel Server for Windows, then contact your account manager or Oracle Global Customer Support to obtain one.
