Upgrade Guide for DB2 UDB for z/OS > Upgrading a Database from the Mainframe >

Preparing the z/OS Host Environment

Upgrades: All upgrades.

Environments: Development (mainframe-centric) environment and Production environment.

This topic is part of an upgrade process. See How to Perform the Upgrade.

When you run the Siebel Upgrade Wizard on the midtier, it generates files that are stored in the midtier output directory that you specified in Table 22. When prompted by the Upgrade Wizard when it reaches Pause #1, you must transfer these files from the output directory on the midtier into datasets on the z/OS host.

Once you have transferred these files, you need to create and populate the target datasets as instructed. You will also need to modify the populated target datasets to meet your job execution requirements. To accomplish these tasks, complete the following procedures:

• Prerequisites for Upgrade Procedures on the z/OS Host
• Transferring JCL, SQL, and Binary Files to the z/OS Host
• Customizing the JCL UNIT Parameter Value
• Defining and Allocating z/OS Setup Datasets
• Setting Up the Upgrade Environment on the z/OS Host
• Preparing for Table Creation (PRET) on the Source Database
