Overview

This self-paced course with hands-on exercises is also available as classroom course IBM MQ V9 Application Development (Windows Labs) (WM513G).

This course helps you develop the skills that are necessary to implement various application requirements on IBM MQ versions up to and including IBM MQ V9.0.2. It focuses on procedural application development for IBM MQ.

The course begins by describing IBM MQ and the effect of design and development choices in the IBM MQ environment. It then covers IBM MQ application programming topics such as methods of putting and getting messages, identifying code that creates queue manager affinities, working with transactions, and uses of the publish/subscribe messaging style.

Finally, the course describes the IBM MQ Light interface, introduces Advanced Message Queuing Protocol (AMQP), and explains how to set up an AMQP channel and how to interface with IBM MQ Light.

Hands-on exercises throughout the course reinforce the lecture material and give you experience with IBM MQ clients.

Audience

This course is designed for application developers and architects who are responsible for the development and design of IBM MQ applications.

Prerequisites

• Successful completion of Technical Introduction to IBM MQ (WM103G), or comparable experience with IBM MQ
