About this book

 

WebSphere MQ for iSeries V6 is part of the IBM WebSphere MQ set of products. It provides application programming services on the iSeries platform that allow a new style of programming. This style enables you to code indirect program-to-program communication using message queues.

This book:

• Gives a full description of the WebSphere MQ for iSeries programming interface in the RPG programming language.

• Contains information on how to build an executable application.

• Contains descriptions of sample programs.

Notes to users

1. This book describes the WebSphere MQ for iSeries programming interface only in the RPG-ILE programming language.

2. There are two approaches we can take when using the MQI from within an RPG program:

   • Static Bound Calls to the MQI procedures.

   • Dynamic calls to the QMQM program interface.

     If you require details of the RPG-OPM programming language, refer to the MQSeries Application Programming Reference (RPG) V4R2 manual.

   Using bound calls is generally the preferred method, particulary when the program is making repeated calls to the MQI, as it requires less resource.

   New functionality is only available through the Static Bound Call interface.

For information on how to design and write applications that use the services WebSphere MQ provides, see the WebSphere MQ Application Programming Guide.
