Process of Tuning Siebel Upgrade Performance

Platforms: Windows and UNIX only.

Note: This process is optional.

Use this process to run test upgrades in the 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. To implement more advanced tuning, including high-availability tuning, contact your Oracle sales representative for Oracle Advanced Customer Services.

Also use this process to test the additive schema changes feature. This 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. Test the additive schema changes feature to verify that it does not adversely affect the operation of the application.

Perform this process in the test environment. Do not perform this process in the production environment.

Note: Links to other topics in this guide are provided throughout this chapter. These links are meant to provide additional information that cannot be provided in these brief overviews. You must, however, perform the upgrade in the proper order. For information on general planning, see this chapter as well as Siebel Database Upgrade Planning and Application Planning for a Siebel Upgrade To begin the process of upgrading your Siebel database, see Preparing for Siebel Database Upgrade then refer to each subsequent chapter.

Review the following upgrade planning and performance tuning resources before performing this process:

  • About Siebel Additive Schema Changes Mode

  • 478308.1 (Article ID) on My Oracle Support. This document was previously published as Siebel Technical Note 616. This article describes the strategies for minimizing production environment downtime during an upgrade. The steps that follow are intended primarily for use with the baseline guidelines described in 478308.1 (Article ID).

  • Tuning the Siebel Upgrade Files This chapter provides detailed information on how to use Upgrade Tuner.

UNIX deployments. You must have a Siebel Server installed on a Windows host to run the Upgrade Tuner. To obtain a Windows version of Siebel Server, contact your account manager or Oracle Global Customer Support.

Caution: Do not use this topic to tune upgrade performance on IBM z/OS. Instead, refer to Siebel Database Upgrade Guide for DB2 for z/OS.
