My webMethods Server Clustering Requirements
In My webMethods Server, a cluster is defined as multiple My webMethods Server instances that point to the same MywebMethodsServer database component. A cluster can include My webMethods Server installations on different machines, server instances within a My webMethods Server installation, or both.
This section is intended for use with the rest of the upgrade procedure. You must perform all documented tasks for your products in the order they are written, with the additional tasks or exceptions noted below.
Install
Universal Messaging before installing
My webMethods Server.
Note: Starting in 10.0, My webMethods Server clusters no longer use the server database to exchange JMS events or as a JMS provider. Instead Universal Messaging is required for synchronization among the cluster nodes.
When you install the new
My webMethods Servers, create a cluster that matches your old cluster. You can install the new
My webMethods Servers in parallel.
When you install the fixes on the new
My webMethods Servers, you can install the fixes in parallel.
You do not need upgrade the Software AG Infrastructure as instructed in this guide.
When you shut down the old products, shut down all cluster nodes.
