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.
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.
You enabled global security for the WebSphere Application Server cell, created users and user groups, and created clusters to host the application and data grid.
