IMS installation verification program (IVP) overview

The installation verification program (IVP) is provided by IBM® to test the product installation of IMS and verify that the major functions and features are working.

The jobs and tasks of the IVP build a sample IMS system and provide several sample applications that are used to verify specific components of IMS. Use the IVP to verify that IMS was installed properly and that the major functions and features of IMS are working.

During the IVP process, you run a combination of jobs and perform a set of tasks to create a fully executable sample IMS system. After the jobs and tasks of the IVP are run and completed successfully, you exercise the system by using the sample applications that are either provided by the IVP or downloaded from the IMS website. You submit the IVP jobs and tasks manually, verify the jobs, and perform the tasks that make up the IVP process.

An IVP job is JCL that you run. An IVP task is something that you need to manually perform. The IVP provides online help with step-by-step instructions for these jobs and tasks. It also provides customized JCL, IMS stage 1 system definition input, database descriptions (DBDs), program specification blocks (PSBs), Message Format Services (MFSs), and application programs. Some of these application programs are run through the IVP jobs and tasks.
