Process of Tuning the Upgrade Performance
Upgrades: All upgrades.
Environments: Production test environment only. Does not apply to production environment.
This process is optional.
This process is part of a roadmap. See Roadmap for Performing a Siebel Database Upgrade.
Use this process to run test upgrades in the production test environment so you can tune upgrade performance. Improving upgrade performance reduces downtime when you perform the production environment upgrade. The steps in this process cover standard performance tuning. For help with this process and to implement more advanced tuning, contact your Oracle sales representative for Oracle Advanced Customer Services to request assistance.
You can also use this process to test the additive schema changes feature to verify that it does not adversely affect application functionality. The additive schema changes feature allows you to perform part of the upgrade on the production database without taking it offline. This reduces the downtime required to upgrade the production database.
Perform this process in the production test environment. Do not perform this process in the production environment.
Review the following upgrade planning and performance tuning resources before performing this process:

This document describes strategies for minimizing production environment downtime during an upgrade. The steps outlined in this topic are intended primarily for use with the baseline best practices described in Technical Note 616.
Tuning the Siebel Production Upgrade Scripts This chapter provides information on how you can improve the performance of the production environment upgrade by tuning the production upgrade scripts in a production test environment.
