Installing IBM MQ for z/OS

Installation tasks that are associated with installing IBM® MQ on z/OS® systems are grouped in this section.

About this task

IBM MQ for z/OS uses the standard z/OS installation procedure. It is supplied with a Program Directory that contains specific instructions for installing the program on a z/OS system. You must follow the instructions in the appropriate Program Directory. For download links for the Program Directories, see IBM MQ for z/OS Program Directory PDF files.

The Program Directory includes not only details of the installation process, but also information about the prerequisite products and their service or maintenance levels.

SMP/E, used for installation on the z/OS platform, validates the service levels and prerequisite and corequisite products, and maintains the SMP/E history records to record the installation of IBM MQ for z/OS. It loads the IBM MQ for z/OS libraries and checks that the loads have been successful. You then have to customize the product to your own requirements.

Before you install and customize IBM MQ for z/OS, you must decide the following:

Whether you are going to install one of the optional national language features. See National language support.
Which communications protocol and distributed queuing facility you are going to use. See Communications protocol and distributed queuing.
What your naming convention for IBM MQ objects will be. See Naming conventions.
What command prefix string (CPF) you are going to use for each queue manager. See Using command prefix strings.
When upgrading from a previous Continuous Delivery release through the installation of PTFs, decide whether any USERMODs that have been applied to IBM MQ for z/OS will still be required. Remove the USERMODs before installation of the Continuous Delivery PTFs, or use the SMP/E BYPASS(ID) option on APPLY. If neither of these actions is performed, an SMP/E MODID ERROR GIM38201E will be received.
The PTFs for the latest Continuous Delivery release can be determined by using SMP/E FIXCAT HOLDDATA category IBM.MQ.V9R0Mn, where n is the modification level. For example, category IBM.MQ.V9R0M2 identifies fixes that upgrade IBM MQ for z/OS 9.0 Continuous Delivery to modification level 2.

You also need to plan how much storage you require in your z/OS system to accommodate IBM MQ; Planning your storage and performance requirements on z/OS helps you plan the amount of storage required.
