In this presentation, you will see specifically how you go about configuring IBM WebSphere Application Server to use a DataPower XC10 session data grid. There are two parts to this. You will first learn how you configure a session data grid for a server then you will learn how you configure a session data grid for an individual application.


Session data grid

� Extension of legacy session management caching mechanism in WebSphere Application Server

� Extensions to WebSphere Application Server administrative console to support DataPower XC10 session management caching

� Two ways to create the grid – Create data grid on the appliance and then point WebSphere Application

Server to the cache – Create the data grid on the appliance directly from the WebSphere Application

Server administrative console


Before you see how to configure a session data grid, here is a recap of its functionality. IBM WebSphere DataPower XC10 supports session data grid for WebSphere Application Server. Session management data caching exists in current releases and previous releases of WebSphere Application Server. DataPower XC10 provides extensions so that WebSphere Application Server can now use the appliance for the session data cache, instead of relying on local JVM memory or data base storage. You can create the session data grids ahead of time in the appliance, and then using the WebSphere Application Server administrative console, you can associate servers directly with the data grid that you’ve already created. Alternatively, you can use the WebSphere Application Server administrative console to create the session data grid on the appliance at the time you enable the server for session data caching.

DataPower XC10 will provide the client code and any necessary plug-ins so that there is a seamless connection from WebSphere Application Server to the DataPower XC10 appliance. WebSphere Application server can be configured through its administrative console to offload session data for HTTP requests to a data grid on the DataPower XC10 appliance. You can configure this connection from an entire set of applications on a server or for individual applications.

Here is more detail about the connection information you supply in WebSphere Application Server about the DataPower XC10. In Step one, you check enable session management. In Step two, you type the IP or host name of the DataPower XC10. In Step three, you type the User name and Password that the DataPower XC10 administrator has provided to you. In Step four, you click Test connection… to verify that you can access the DataPower XC10 and that the user credentials are correct. A successful connection will result in a popup window with the message Connection to appliance <ip address or host name> is successful.

When you review these settings later, the user credential information is not visible but the credentials are retained in the configuration for the connection. However, you will need to type the credentials again later if you subsequently want to test the connection using the Test connection… button.

3. In Step 15 you specify session management settings


You can specify eXtreme Scale session management settings in the administrative console during the installation of a WebSphere Application application. Other applications running on the same server will not participate in the session caching with this specific data cache – only the application you configure. Item one shows the beginning of the installation of an application. In the “Preparing for the application installation” dialog, select “Detailed – show all installation options and parameters”, shown in Item two. Then proceed normally within the application installation dialogue to “eXtreme Scale session management setting”. Item three shows that this new step is near the end of the application installation sequence. The next slide shows you the subsequent settings for the application installation sequence.

14 session Data grid configuration

The steps for configuring an application to cache session data on the DataPower XC10 are identical to configuring an application server at this point. You must first check Enable session management as shown in Item one. Then type in the IP or the host name of the DataPower XC10, shown in Item two. As shown in Item three, you must then type the credentials for the appliance. Note that when you revisit this screen later, the credentials will still be active but are not shown on the screen. Then finally, click Test connection… to test the connection, shown in Item four. You see that the Persist sessions in a new grid… is primed with a suggested data grid name. Use this name or type in your own name if you want to define a new data grid name at this point, and then click Next to proceed with the application installation. The next slide shows you how to select a predefined data grid from the appliance.


Setting an application to use an existing data grid

� To use a predefined data grid on the DataPower XC10:

1. Click “ Persist session in an existing grid…”

2. Click Browse

3. Click the name of the active data grid

� You then continue with traditional application installation by clicking Next to proceed

This example assumes you have already provided valid connection information within the application installation steps. If you want to use a predefined data grid on the DataPower XC10, you first select Persist session in an existing grid…, shown in Item one. Then click the Browse button, shown in Item two. A popup window opens with the list of data grids on the DataPower XC10 that are available for you to use, depicted in Item three. Click the data grid name you want to use. At this point you can continue with traditional application installation by clicking Next at the bottom of the screen.


Review the application’s session management settings

� Enterprise Applications ��(appname) ��Session management ��eXtreme Scale session management settings

You can review or change the application’s session management setting by navigating to Enterprise Applications > (application name) > Session management > eXtreme Scale session management settings. Note that the XC10 appliance console credentials are not shown. The credentials are saved within the configuration so that the application’s connection to the DataPower XC10 is still active. However, if you choose to test the connection to the appliance from this screen, or if you change the settings, you must first provide the credentials.



Summary

� Session data grids can be created from – DataPower XC10 appliance console – WebSphere Application Server administrative console

� A new or existing session data grid can be configured for a server

� A new or existing session data grid can be configured for an individual application


Session data grids can be created from DataPower XC10 appliance console or from WebSphere Application Server administrative console during application install. A new session data grid can be created and configured for a server so all applications installed and running that server will use that session grid. A server can also be configured to use an existing session data grid. A new session data grid can be configured for an individual application during install. In addition, an application being installed on WebSphere can be configured to use an existing session data grid.
