About Generating the Upgrade Files

Upgrades: All upgrades.

Environments: All environments

After you have created the staging database, you generate the upgrade files by running the Upgrade Wizard against the staging database. The upgrade files are then transferred to the z/OS host where the JCL preparation process is done. The JCL preparation process constructs all the JCL to run the preupgrade and upgrade (in-place) processes for both the staging and target databases.

The midtier file generation process can be performed ahead of the in-place target database upgrade provided no further changes are made to the target database schema.

Note: The procedures in this chapter use Siebel-Scheduled job execution, but you can also choose to use a third party job scheduler. For information on choosing a scheduler, see Executing Jobs Using Siebel-Scheduled Mode or Vendor-Scheduled Mode.
