Tuning can significantly reduce overall downtime during your Siebel 7 production upgrade. Examples of upgrade tuning include elimination of SQL statements that do not affect any data, parallelization of the most expensive SQL statements, and parallelization of table creation, table rebuilds, and index creation.
The upgrade scripts provided by Siebel are generic in nature and migrate the entire application functionality to the upgraded Siebel version given an upgrade path, database platform, and language. In the three cases described below, tuning can help optimize the production upgrade scripts and minimize down time.
The purpose of tuning the production upgrade scripts is to minimize application downtime, thereby reducing the impact to your brand or image, loss of productivity, and potential loss of revenue. Plan your resources and test environment for tuning the upgrade scripts before you perform a production upgrade to Siebel 7.
Tuning the upgrade scripts can only be performed by Siebel Expert Services or Global Competency, who are provided with the necessary documentation, training, and support by engineering. Contact Siebel Expert Services or Global Competency to get an estimate of your tuning effort. Resource estimation should also account for a test environment that contains production data for tuning of the upgrade scripts.
