IBM MQ Administration for z/OS with Multi-Platform Environments

This course is specifically aimed at those organisations using IBM MQ on multiple platforms. The course is suitable for organisations using all IBM MQ versions up to and including IBM MQ Version 9.
The course covers the operation, administration and support of IBM MQ systems in z/OS and in multi-platform environments (Linux, Windows and/or Windows). The course teaches the skills required to install, configure and manage an IBM MQ messaging system.
It is a 'hands-on' course with several challenging practical exercises.

What you will learn

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

  • understand the concepts of Queues, Queue Managers and MQ messages
  • describe IBM MQ program design considerations and the MQI
  • explain triggering, syncpoints and message grouping and segmentation
  • discuss Distributed Queuing enablement
  • understand and describe Clustering
  • define and manage MQ objects such as queues and channels using 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
  • navigate the MQ file system and identify running MQ processe
  • outline the principles of MQ logging and units of work
  • rebuild a damaged queue
  • review the security mechanisms available to the distributed implementations of IBM MQ
  • monitor an MQ system using a range of monitoring tools
  • 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

All those responsible for administering IBM MQ in multi-platform environments.


An understanding of distributed computing environments, as well as skills in IBM z/OS.
