Target Audience

The course is aimed at developers who require the basic skills of designing and writing application programs which issue calls to the Message Queuing Interface (MQI). The course is aimed at experienced applications developers who need to develop programs which use WebSphere MQ messaging techniques.

Pre-requisites

A basic understanding of the concepts of WebSphere MQ message queuing and COBOL programming. These can be gained by attending courses MQ01 and BT05.

Course Objectives

Whilst covering the basics of WebSphere MQ, this course also aims to give an insight into the programming and issuing of calls to the Message Queuing Interface. On completion of this course the student will be able to:

Understand basic messaging concepts
Understand queues and message management
Understand and use the supplied panels, utilities and programs in a batch and CICS environment to manipulate WebSphere MQ objects

Course Format

Demonstration sessions and practicals make up a large part of the course, allowing delegates to reinforce the lectures given. During these sessions the delegate will gain experience of Websphere MQ, specifically MQI.

Examples are used extensively, ranging from simple code snippets to full applications with complete ‘real world’ functionality. These are supplied at the start of the course and it is encouraged that the delegates execute and ‘experiment’ with these under the instructor’s guidance as they are introduced.

These examples are available to take away, along with the delegate’s own work.

The comprehensive Student Guide supplied is fully indexed serving as a useful reference tool long after the course has finished. Delegates will also be able to access a free help-line with technical questions relating to topics covered on the course.
