Integration Server Clustering Requirements

Complete Installation and Upgrade Information for Software AG Products : Upgrading Software AG Products : Critical Requirements and Recommendations For Successful Upgrade : Integration Server Clustering Requirements

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

1. Go to Install 9.9 Products, Prepare Old Environment, Shut Down Old Products, Migrate Database Components, Prepare to Migrate Data, and Upgrade the Software AG Infrastructure and use the instructions to perform the steps below.

a. Install a cluster of 9.9 Integration Servers that matches your old cluster. You can install the 9.9 Integration 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. When shutting down the old products, shut down all cluster nodes.

2. Go to Complete the Integration Server and Hosted Wm Packages Upgrade and use the instructions to perform the steps below.

a. Read the sections at the beginning of the chapter and then run the Integration Server migration utility to migrate server instances from one old Integration Server installation to one Integration 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).

Then run the utility for the other old and 9.9 Integration 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 server instance, perform the rest of the tasks in the chapter. Make sure the 9.9 server instances are processing client requests.

Important:

If the old server instances were not configured to use a Terracotta-based clustering solution, configure the 9.9 server instances to use a Terracotta-based clustering solution. Support for Coherence was discontinued in release 9.0. For instructions, see webMethods Integration Server Clustering Guide 9.9.

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 Integration Server clusters, see the webMethods Integration Server Clustering Guide.
