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

About Using Oracle's Application Expert Services

The Siebel 8.0 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 needs to 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. Alternatively, you can phone Global Customer Support directly to create a service request or get a status update on your current SR. Support phone numbers are listed on My Oracle Support.

Customizing the 8.0 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 from Oracle's Application Expert Services.

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