Customizing the z/OS environment

If you are planning to use a z/OS® environment, you must complete a number of configuration tasks.

About this task

Although you might be installing only one integration node initially, you might want to consider how the product will be used in your organization in a few years time. Planning ahead makes developing your IBM® Integration Bus configuration easier.

The following rules apply to the configuration:
  • You cannot use WebSphere® MQ shared queues to hold data related to IBM Integration Bus as SYSTEM.BROKER queues, but you can use shared queues for your message flow queues.

You can find details of the WebSphere MQ queues that are created and used by IBM Integration Bus on z/OS in mqsicreatebroker command.

When planning to work in a z/OS environment, you must complete the following tasks:
  • Create started task procedures for each integration node that you plan to use. These procedures must be defined, in the started task table, with an appropriate user ID.
  • Decide on your recovery strategy. As part of your systems architecture, you must have a strategy for restarting systems if they end abnormally. Common solutions are to use automation products like Tivoli® NetView® for z/OS or the Automatic Restart Manager (ARM) facility. You can configure IBM Integration Bus to use ARM.
  • Plan for corequisite products, including UNIX System Services, Resource Recovery Services (RRS), and Java™.

    You might also want to include IBM DB2® in your configuration, if your message flows access databases, or WebSphere MQ, to process messages.

  • Set up security. An IBM Integration Bus administrator role includes customizing and configuring, running utilities, performing problem determination, and collecting diagnostic materials. People involved in these activities need IBM Integration Bus authorities. You must set up some security for IBM Integration Bus to work properly. The information that you need to do this is in Configuring integration node user IDs on z/OS.

  • Integrate integration node statistics with SMF; for more information see Message flow accounting and statistics records.
