MQ Application Development

The course will enable delegates to develop the skills needed to design and write programs that issue calls to the Message Queue Interface (MQI). The hands on exercises will give delegates practice of coding MQ calls in COBOL, PL1, RPG, C, C++, C#, .Net or Java. The operating system platform can be either Windows, Linux, UNIX, iSeries or z/OS using IBM MQ. The course is also ideal for preparing delegates for the IBM MQ exams.

The course is delivered at the latest release level and regularly updated to include any new features.  Previous release levels are available on request.

This course is for experienced application developers who will be writing programs that use the messaging and queuing techniques provided by IBM MQ. Systems and Business analysts will also benefit.

Prospective delegates are expected to be experienced application developers in the relevant environment.

No prior knowledge of MQ is required.

On completion of the course delegates will be able to:

• Describe and use the Message Queue Interface.
• Design and write programs to use MQI as implemented on their chosen platform.
• Explain the differences in program design necessitated by the messaging and queuing paradigm.
• Describe, in detail, the different MQI calls.
• Explain the differences in MQI across the different MQ platforms.
• Design and write programs that use the advanced features of the MQI including security, message groups, segmentation and distribution.
