Creating a Schedule for the Upgrade

Develop a plan for your upgrade based on the objectives and constraints for your deployment.

The following procedures may reduce the time required for your upgrade.

• Run selected processes in advance of the upgrade.

  Certain preupgrade tasks can be run at any time prior to the upgrade. These procedures can be performed in advance either for testing purposes or to accommodate down-time constraints.

  Examples of procedures that can be performed by a database administrator in advance of your upgrade include Preparing the Storage Layout of the Schema.

• Prepare select processes to run in parallel.

  If a large table such as S_EVT_ACT is partitioned, it can run in parallel by transferring shipped statements into the numbered SQL statement.
