IBM MQ - MQ for Application Programmers
Duration
4 hours
Overview
This course begins by identifying the basic programming code used by applications to interact with IBM MQ. It describes the MQ messaging process and then delves more heavily into the commands that can be used to get and put MQ messages, and manage MQ objects. Details on programming with MQ in a z/OS environment is provided, explaining core differences when using that platform.
Audience
This course is designed primarily for application developers, but will also be of interest to those that require an overview of programming requirements when dealing with IBM MQ.
Prerequisites
Successful completion of the Interskill IBM MQ - Introduction to IBM MQ course, or equivalent knowledge.
Objectives
- After completing this course, the student will be able to:
- Describe How a Basic Program Uses IBM MQ
- Create Basic Code to Interact with MQ Resources
- Identify Code Used in Various MQ Scenarios
- Identify z/OS Specific MQ Programming Requirements
- Describe how CICS and IMS Can Interact with MQ
