My webMethods Server Clustering Requirements

In My webMethods Server, a cluster is defined as multiple nodes that point to the same MywebMethodsServer database component. Nodes can be My webMethods Server installations on different machines or server instances within a My webMethods Server installation.

a. Install a cluster of My webMethods Server 9.9 installations that matches your old cluster. You can install the 9.9 My webMethods Servers in parallel.

The installation instructions include installing fixes. You can install the fixes in parallel.

b. Perform the rest of the tasks in the chapter except you do not need to upgrade the Software AG Infrastructure. When shutting down the old products, shut down all cluster nodes.

2. Go to Complete the My webMethods Server Upgrade and follow the instructions to perform the steps below.

a. Read the sections at the beginning of the chapter and then run the My webMethods Server migration utility to migrate server instances from one old My webMethods Server installation to one My webMethods Server 9.9 installation. The utility will ask separately about each server instance. The first migration of a server instance must be run alone (that is, not in parallel) because the first migration will make changes to the MywebMethodsServer database component.

Then run the utility on the other old and 9.9 My webMethods Server installations. You can run the utility on the other installations in parallel, because migrations after the first migration only change the local file system.

b. For each My webMethods Server installation, migrate the My webMethods Server infrastructure. You can migrate the My webMethods Server infrastructure on all My webMethods Server installations in parallel.

c. Initialize one cluster node. Then initialize the other cluster nodes, but do not update the host names again. You can initialize the other cluster nodes in parallel.

3. Perform the rest of the steps in this guide, including Complete Final Upgrade Tasks for All Products, and Troubleshooting. That chapter includes a step to configure your products. For instructions on configuring My webMethods Server clusters, see Administering My webMethods Server.
