Installing IMS

The IMS installation task includes the following activities:

• Installing IMS on your z/OS system using the SMP/E installation process.

• Verifying the installation using the IMS Installation Verification Program (IVP) facility.

• Other installation-related activities, such as tailoring your IMS system, customizing your IMS system, and defining resources to IMS.

Most IMS installations involve migrating an existing version of IMS to a newer version rather than installing a new instance of IMS. When an existing installation is migrated, there are migration, coexistence, and maintenance steps and issues to consider as part of the installation process. The migration issues are usually version specific.

Installing IMS Using SMP/E

System modification program/extended (SMP/E) is a z/OS tool designed to manage the installation of software products on your z/OS system and to track the modifications that you make to those products. The IMS code is shipped from IBM on cartridges and you use SMP/E to install IMS onto your computer. You can also use SMP/E to perform maintenance to your IMS.

IMS is delivered in multiple function modification identifiers (FMIDs) that need to be installed depending on what functions you want.

IMS Installation Verification Program (IVP)

The Installation Verification Program (IVP) facility supplied by IMS is an ISPF application that verifies the majority of IMS features and functions of a newly installed IMS. The IVP uses a sample IMS system to perform this verification.

The IVP provides guidance for performing a combination of the following jobs and tasks, depending on your environment:

• Allocating data sets

• Defining the characteristics of an IMS system through the process of system definition

• Establishing IMS interfaces to z/OS and VTAM

• Preparing the IMS system

• Performing an initial program load (IPL) of z/OS

• Preparing the IVP system and IMS applications

• Initializing the IVP system and running IMS applications

You must define the IMS system and you must establish the interface between your IMS system and z/OS before you can run IMS.
