The Access Gateway normally resides in a separate cluster from the TWSS Service Platform components. When setting up the cluster for the Access Gateway, you first install the deployment manager. Then you install the standalone servers and add them to the deployment manager. Finally, before you install the WebSphere® Telecom Web Services Server components, you create the clusters.
You must have completed the following steps:
A simple Access Gateway cluster is illustrated in the following diagram. The message processing flows are deployed on one or more nodes in the cluster, and they exchange data with the shared database (TWSSDB).
Use the ESBProfile for the WebSphere Application Server Network Deployment and WebSphere Enterprise Service Bus. If you need to use an advanced profile, do not select the for development profile. It may cause problems with the WebSphere Application Server SIP container.
You must use the WebSphere Enterprise Service Bus tools for creating new profiles and application servers.
To set up a clustered configuration, you must configure cell-managed server nodes on several servers, with the deployment manager on its own server. Refer to the WebSphere ESB Information Center for additional information about this installation scenario.
