Before you can configure the clusters and the session management, verify the IBM WAS ND V6 software is installed on the Deployment Manager machine (dm) and on both appserver machines (app1 and app2).
Make sure that you choose to install the Application Server Samples. This includes the BeenThere application which we will install later into our topology. If you prefer not to install the Application Server Samples, then download BeenThere separately from the redbook repository (see Appendix B, Additional material for download instructions).
The same software is installed on every WebSphere node, upon which one or more profiles are then configured. Thus, after the WebSphere V6 installation, you first configure a Deployment Manager profile on the Deployment Manager machine. As soon as the Deployment Manager is up and running, you can configure the managed node custom profiles on the Application Server nodes.
