Configuring a uniform cluster

Uniform clusters permit applications to be designed for scale and availability, and can connect to any of the queue managers within that uniform cluster.

About this task

Uniform clusters use IBM MQ clustering for communication between queue managers, and balancing of workload between queues. However they differ from typical IBM MQ clusters in the following ways:

Uniform clusters typically have a smaller number of queue managers in the cluster. You should not create a uniform cluster with greater than 10 queue managers.
Every member of the cluster has near-identical configuration.
The cluster is typically used by a single application, or group of related applications.
The number of application instances connecting to the cluster should be greater than, or equal to, the number of queue managers.

You can simplify both creating a uniform cluster, and subsequently keeping the configuration between the uniform cluster members identical, by using the automatic configuration and automatic clustering support.
