Cluster Upgrade Guidelines

Edit online

In IBM My webMethods Server, a cluster is defined as multiple IBM My webMethods Server instances that point to the same MywebMethodsServer database component. A cluster can include separate IBM My webMethods Server installations as well as server instances within an IBM My webMethods Server installation.

This section is intended for use with the rest of this chapter. You must perform all documented tasks for your products in the order they are written in this chapter, with these additional tasks or exceptions:

  • Install Universal Messaging before installing IBM 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 IBM My webMethods Servers, create a set of installations that matches your old cluster. You can install the new IBM My webMethods Server installations in parallel.
  • When you install the fixes on the new IBM My webMethods Server installations, you can install the fixes in parallel.
  • You do not need to upgrade the Software AG Infrastructure and you can ignore the upgrade instructions for IBM webMethods Infrastructure in this guide.
  • When you shut down the old products, shut down all cluster nodes.
  • When you migrate server instances from old My webMethods Server installations to new IBM My webMethods Server installations, you can migrate the installations in parallel.
  • When you initialize the server instances, you can initialize them in parallel.

Configure the cluster as instructed in Administering IBM My webMethods Server.
