IBM MQ z/OS System Administration


This newly revised and upgraded three-day course covers the operation, administration and support of IBM MQ systems and applications in a z/OS environment. Segments on RACF-based security and SSL are also included in this course.
The course is taught combining formal classroom tuition with demanding hands-on practical exercises.
Regularly updated to reflect the new releases of the product, this course covers the administration of IBM MQ up to and including Version 8x.

This course is also available for one-company, on-site presentations and for live presentation over the Internet, via the Virtual Classroom Environment service.

Objectives

On successful completion of this course you will be able to:

  • investigate how IBM MQ PSIDs, storage classes and buffer pools have been set up in your installation
  • define and manage MQ objects such as queues and channels using ISPF panels, MQ script commands and the MQ Explorer
  • set up triggered queues
  • establish distributed queuing channels both directly to an adjacent Queue Manager and indirectly through one or more intermediate Queue Managers
  • inspect and process messages on the Queue Manager's dead letter queue
  • troubleshoot distributed queuing problems
  • implement a basic MQ cluster
  • create connections between an MQ client and an MQ Queue Manager using both an environment variable and a client channel connection table
  • list the benefits of queue sharing groups
  • outline the principles of MQ logging and units of work
  • review the security mechanisms available to the z/OS implementation of IBM MQ
  • explain how IBM MQ interfaces with RACF
  • describe how publish/subscribe differs from traditional point-to-point queuing
  • test a simple publish/subscribe implementation
  • compare the z/OS implementation of IBM MQ with the distributed implementations of IBM MQ

Who Should Attend

Those who will administer IBM MQ for z/OS. Administration of IBM MQ on the distributed platforms (Windows, UNIX, Linux, OS/400, AIX, Solaris, etc.) is covered in the course IBM MQ System Administration for Linux, UNIX & Windows Environments.

Prerequisites

Attendees must be familiar with IBM MQ at a conceptual and terminological level. This can be achieved by attending the course Technical Introduction to IBM MQ, or through prior practical experience. Attendees must also have a working knowledge of TSO/ISPF and JCL and a conceptual-level knowledge of the z/OS computing environment.
