Lesson 1.1: Understand the topology and get the tutorial files

To prepare the environment for the tutorial, configure WAS security.

You configure administration and application security using internal file-based federated repositories as a user account registry.

This lesson guides you through the sample topology and applications that are used to in the tutorial.

To begin running the tutorial, download the applications and place the configuration files in the correct locations for the environment. You can download the sample application from the WebSphere eXtreme Scale wiki.

WAS sample topology

This tutorial guides you through creating four WebSphere Application Server application servers to demonstrate using the sample applications with security enabled. These application servers are grouped into two clusters, each with two servers:

In this deployment topology, the s1 and s2 application servers are the client servers that access data that is being stored in the data grid. The xs1 and xs2 servers are the container servers that host the data grid.

The catalog server is deployed in the deployment manager process by default. This tutorial uses the default behavior. Hosting the catalog server in the deployment manager is not a recommended practice in a production environment. In a production environment, you should create a catalog service domain to define where catalog servers start. See Create catalog service domains in WAS for more information.

Alternative configuration: You can host all of the application servers in a single cluster, such as in the appCluster cluster. With this configuration, all of the servers in the cluster are both clients and container servers. This tutorial uses two clusters to distinguish between the application servers that are hosting the clients and container servers.

Figure 1. Tutorial topology

Client browser contacts appCluster cluster, which contains the EmployeeMangement Module application. The application talks to the deployment manager, which contains the deployment manager, and the xSCluster cluster, which contains the data grid containers.


In this tutorial, you are using two applications and one shared library file:

Get the tutorial files

  1. Download the and files. You can download the sample application from the WebSphere eXtreme Scale wiki.

  2. Extract the file to a directory for viewing the binary and source artifacts, for example the /wxs_samples/ directory. This directory is referred to as samples_home for the remainder of the tutorial. For a description of the contents of the file and how to load the source into the Eclipse workspace, see the README.txt file in the package.

  3. Extract the file to the samples_home directory. The file contains the following security configuration files that are used in this tutorial:

    • catServer2.props

    • server2.props

    • client2.props

    • securityWAS2.xml

    • xsAuth3.props

About the configuration files

The objectGrid.xml and objectGridDeployment.xml files create the data grids and maps that store the application data.

These configuration files must be named objectGrid.xml and objectGridDeployment.xml. When the application server starts, eXtreme Scale detects these files in the META-INF directory of the EJB and web modules. If these files are found, it assumed that the JVM acts as a container server for the defined data grids in the configuration files.

objectGrid.xml file

The objectGrid.xml file defines one ObjectGrid named Grid, which has one map, Map1, that stores the employee profile for the application.

<?xml version="1.0" encoding="UTF-8"?>

<objectGridConfig xmlns:xsi=""

        <objectGrid name="Grid" txTimeout="15">
            <backingMap name="Map1" />



objectGridDeployment.xml file

The objectGridDeployment.xml file specifies how to deploy the Grid data grid. When the grid is deployed, it has five partitions and one synchronous replica.

<?xml version="1.0" encoding="UTF-8"?>

<deploymentPolicy xmlns:xsi=""

    <objectgridDeployment objectgridName="Grid">
        <mapSet name="mapSet" 
                maxSyncReplicas="1" >
            <map ref="Map1"/>


Lesson checkpoint

In this lesson, you learned about the topology for the tutorial and added the configuration files and sample applications to the environment.
