Perform Preupgrade Tasks

This phase prepares the Siebel database for upgrade and includes such tasks as closing database connections, clearing pending workflow tasks, disabling customized triggers and editing and validating the storage control file.

Note: The Siebel upgrade process is not designed to support custom database triggers. If you have created customized triggers for the Siebel schema to be upgraded, you must remove them before starting the Siebel upgrade process. You can re-create these objects once the Siebel upgrade completes successfully.
