Technical introduction to IBM MQ
This course provides a sound introduction to (and understanding of) IBM's MQ (formerly WebSphere MQ and before that, MQSeries) messaging system, at both a conceptual and terminological level, and is essential for all personnel who will be working in an IBM MQ environment. This course is appropriate for both the z/OS and multi-platform environments.
On successful completion of this course attendees 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.
All technical and management personnel requiring an introduction to IBM MQ.
A knowledge of one or more IT applications environments.
