mq-uniform-clusters
Uniform clusters are a specific pattern of an IBM MQ cluster that provides a highly available and horizontally scaled small collection of queue managers. These queue managers are configured almost identically, so that an application can interact with them as a single group.
IBM MQ 9.1.x introduced the ability to define a Uniform Cluster, This makes it easier to configure a set of matching queue managers and adds intelligent balancing of connected applications, ensuring messaging workload and processing is spread evenly across the queue managers.
Demo
This video on YouTube takes you through a very simple demo of a Uniform Cluster containing three queue managers. Many of the scripts and configuration to run this demo can be found in 'demo/Linux'.
As well as the Linux demo, a demo using Docker can be found in 'demo/Docker'
'request-reply' contains a more advanced variant of the demonstration using the requester-responder application pattern. It provides sample C applications demonstrating relevant features of the MQ API, and does therefore require a suitable development environment to compile and run these applications.
'pubsub' demonstrates certain publish subscribe scenarios which can work well in Uniform Clusters, by avoiding single queue manager affinities.
