Siebel Database Upgrade Guide for DB2 for z/OS > How the Siebel Database Upgrade Works >

About Using Oracle's Advanced Customer Services

The Siebel CRM upgrade process on DB2 for z/OS is designed to run in all standard Siebel implementations. It is built on the assumption that data exists in all Siebel tables and that all this data must be migrated.

In reality, your implementation has probably been customized to suit your business so, for example, you might not use all of the Siebel tables shipped or they might contain varying amounts of data. To accommodate this fact, the upgrade process is customizable, for example, you can eliminate upgrade jobs that run on empty tables, or you can choose to run unload jobs simultaneously.

Global Customer Support provides support for all standard z/OS upgrades but it does not support customized upgrades. If you require help with a standard upgrade, create a service request (SR) on My Oracle Support. You can log service requests by accessing My Oracle Support (Service Request tab), or by using your existing phone support numbers to contact Oracle Global Customer Support

Customizing the upgrade scripts is a complex process and, for this reason, if you want to customize the upgrade scripts, you must contact your Oracle sales representative for Oracle Advanced Customer Services to request assistance.

This guide describes a number of upgrade customization tasks that you can perform where the assistance of Oracle's Advanced Customer Services is required.

CAUTION:  You must contact Oracle's Advanced Customer Services before performing tasks where such help is noted as a requirement. If you do not, you might invalidate your support agreement.
