How the Upgrade Configuration File and SQL Files Are Created

When you run the Database Configuration Wizard, it does the following:

• Collects configuration information.

• Creates a primary upgrade configuration file (UCF). This file maps the information you entered in the Database Configuration Wizard to environment variables. When the Siebel Upgrade Wizard is performing the steps in a driver file, it uses these variables to generate the command contained in each step.

• Prompts you to start the Siebel Upgrade Wizard. The wizard forwards the information in the UCF file to an SQL generator that creates or populates SQL files on the midtier with the required commands to perform the upgrade. You then transfer these files to the z/OS host and apply them.

  In some cases, you will have to modify the generated SQL files as required by Alerts, Bulletins, or Siebel CRM Update Guide and Release Notes on My Oracle Support before you transfer the files to the z/OS host.
