Round Robin Messaging Overview
The Round Robin Messaging v1.0.0 (RRM) application is a MQ application that will move messages from a single input queue to 'n' output queues ('n' can be up to 99) in a round robin fashion.
- There are 2 reasons people may be interested in RRM:
- The MQAdmin does not want to go through the process of configuring and managing an MQ cluster repository.
- The company is not using MQ clustering and the application has a simple need to distribute messages across several queues. A good example would be to spread the message load across multiple instances of the same application.
If your application is having issues processing the volume of messages from its input queue, parallelism may help the situation. If you do not want to use MQ clustering and you can run multiple instances of your application, RRM is the solution to your problem.
In RRM, you define your source (input) queue (i.e. Q1) and the target (output) queues (i.e. QA, QB, QC & QD). Hence, you start 4 instances of your application with each processing messages from a single target queue (i.e. instance #1 reads messages from QA, instance #2 reads messages from QB, etc.). When RRM is started, it will get messages from the source queue and move them to the target queues. Since there are 4 target queues, each queue will get 25% (one-quarter) of the messages from the source queue. Messages put to each target queues are an exact replicate of the original message from the source queue (including the message's MQMD).
RRM performs each MQGET and the subsequent MQPUT will be done under a Unit of Work (UOW), so that message integrity is kept.
The RRM binaries/executables (32-bit & 64-bit) are available for all major platforms: AIX, HP-UX IA64, IBM i (OS/400), Linux x86, Linux on POWER, Linux on System z (zSeries), Solaris SPARC, Solaris x64, Windows and z/OS.
