To prepare your environment for the tutorial, you must configure WebSphere® Application Server security. Enable administration and application security using internal file-based federated repositories as a user account registry. Then, you can create server clusters to host the client application and container servers. You also must create and start the catalog servers.
Create two server clusters in your WebSphere Application Server configuration: The appCluster cluster to host the sample application for the tutorial and the xsCluster cluster to host the data grid.
After configuring the server cluster and security, you must define where catalog servers start.
You enabled security in WebSphere Application Server, and created the server topolgy for WebSphere eXtreme Scale.
