You can have more than one region on a system. Each region runs as a started task.
The Install Utility uses the site-specific information you collected during preinstallation to generate the jobs that build the regions. If you need additional regions, you can reuse the Install Utility to create them.
Note: If you use CA MSM to deploy the software on different systems before you perform the setup, you must use the Install Utility on a target system to perform the setup on that system.
Important! After you have run a setup job, you cannot alter the results using the setup software. You can use the setup software to create a region, or you can manually customize the existing region's JCL.
