In Version 18.0, what has traditionally been referred to as installation is now separated into the following four distinct operations:
These operations can be performed using the same tools as in previous releases, such as Electronic Software Delivery (ESD) to download a PAX file and the CAISAG program to generate a configuration job stream. Now, with Version 18.0, you can perform all four operations for z/OS using CA Mainframe Software Manager (CA MSM).
Regardless of the tools used, a clear distinction is made between installing the software and configuring it to meet the needs of an operational environment. With Version 18.0, no customization takes place during installation and product selection now occurs during configuration. As a result, the contents of the installed libraries are identical at all customer sites except for a few operating system and optional interface differences.
After the software is installed, you can deploy it to one or more target systems within your environment. You can perform deployment by copying files or by using CA MSM in z/OS. Deployment is required only if you use CA MSM for configuration; otherwise, deployment is optional.
Configuration is the creation of an executable CA IDMS instance tailored to the needs of a specific operational environment. For example, you may create test and production configurations that have different characteristics to meet their different operational requirements. In Version 18.0, configuration can be done using a CAISAG generated job stream or CA MSM in z/OS. In either case, all customizations are kept separate from CA-distributed modules.
The following diagram illustrates the installation process without the use of CA MSM:
