Clustering: Best practices
Clusters provide a mechanism for interconnecting queue managers. The best practices described in this section are based on testing and feedback from customers.
A successful cluster setup is dependent on good planning and a thorough understanding of IBM MQ fundamentals, such as good application management and network design. Ensure that we are familiar with the information in the related topics before continuing.
- Clustering: Special considerations for overlapping clusters
This topic provides guidance for planning and administering IBM MQ clusters. This information is a guide based on testing and feedback from customers.- Clustering: Topology design considerations
This topic provides guidance for planning and administering IBM MQ clusters. This information is a guide based on testing and feedback from customers.- Clustering: Application isolation using multiple cluster transmission queues
We can isolate the message flows between queue managers in a cluster. We can place messages being transported by different cluster-sender channels onto different cluster transmission queues. We can use the approach in a single cluster or with overlapping clusters. The topic provides examples and some best practices to guide you in choosing an approach to use.- Clustering: Planning how to configure cluster transmission queues
You are guided through the choices of cluster transmission queues. We can configure one common default queue, separate default queues, or manually defined queues.- Clustering: Migration and modification best practices
This topic provides guidance for planning and administering IBM MQ clusters. This information is a guide based on testing and feedback from customers.- Clustering: Using REFRESH CLUSTER best practices
You use the REFRESH CLUSTER command to discard all locally held information about a cluster and rebuild that information from the full repositories in the cluster. We should not need to use this command, except in exceptional circumstances. If we do need to use it, there are special considerations about how we use it. This information is a guide based on testing and feedback from customers.- Clustering: Availability, multi-instance, and disaster recovery
