About the Siebel Upgrade Wizard and Driver Files

Upgrades: All upgrades.

Environments: All environments

The Upgrade Wizard generates the files required to perform the upgrade of the Siebel database on the z/OS host and also makes changes to the Siebel database directly. After the Siebel Upgrade Wizard starts, it executes this process:

• Reads the upgrade configuration file (UCF) generated by the Database Configuration Wizard

• Calls a driver

• Passes the information in the UCF to the driver, which then passes UCF file information to, for instance:

  • the ddlimp utility, which executes ddl-type SQL commands

  • the dataimp utility, which executes data-related SQL commands

If ddlimp or dataimp (or any of the database utilities) encounter errors, they stop. When the errors have been corrected, you can launch the Siebel Upgrade Wizard, and the upgrade resumes from where it stopped.

The Siebel Upgrade Wizard pauses on four occasions during the upgrade file generation process. At each pause, you must transfer the files that the Upgrade Wizard has generated to the z/OS host and execute them before you resume the upgrade. Message text at each pause informs you of the tasks you must perform.

The files generated by the Upgrade Wizard are output by default to the DBSRVR_ROOT\DB2390\dboutput\upgrade directory (Windows) or DBSRVR_ROOT/DB2390/dboutput/upgrade directory (UNIX) or to the DDL Output Directory you specified when you ran the Database Configuration Wizard.
