You can create a separate cluster for the Service Platform components. This cluster will also contain the Web service implementations, which you will install on the same servers as the Service Platform components.
The cluster for the Service Platform components and Web service implementations must be created on WebSphere Application Server Network Deployment, version 6.1.0.29 or 7.0.0.7.
A simple cluster is illustrated in the following diagram. In the illustration, the Service Platform components are deployed on the same node as the Web service implementations, as required. The TWSS Administration Console is deployed on the deployment manager node, as required. There are unique database instances for theUsage Record component Web service and the Service Platform component configuration data. However, this is not required.
If possible, use the default profiles for WebSphere Application Server Network Deployment. Also, avoid customizing the profile with the Profile Management Tool. If you need to use an advanced profile, do not select the for development profile. Doing so can cause problems with the WebSphere Application Server SIP container.
After you have installed the prerequisite software, you must federate the application server nodes into the deployment manager. Then, you can create the cluster using the Integrated Solutions Console. You can create the first cluster member from one of the application servers you federated into the deployment manager. After you have created each application server, you must add each application server to the network deployment manager cell. Additional cluster members can be added using the Integrated Solutions Console at a later time, as needed.
