Abstract

OVERVIEW Disclosed is a set of techniques for low cost implementation of message grouping within a message broker product such as IBM's MQSeries* for OS/390*. This implementation imposes a few acceptable restrictions on the more general implementation already available on messaging products such as MQSeries products on distributed platforms eg AIX*) restrictions. These enable the implementation to achieve acceptable performance with low development cost. While the implementation described herein exploits some changes to the internals of the message broker product, some of the techniques could be used to build an acceptable alternative implementation on top of an unchanged message broker product. MESSAGE GROUPING The key functions of message grouping as implemented by messaging products such as IBM's MQSeries products on distributed platforms (i.e. platforms other than OS/390) are: Each group message is associated with a 24-byte GroupId and a
