Flexible performance, according to requirements Service policies for different applications can be defined independently. The Intelligent Management feature always tries to provide the service as defined. It warns you if the available hardware cannot provide the requested service level.

246 WebSphere Application Server V8.5 Concepts, Planning, and Design Guide Low maintenance effort Because the Intelligent Management feature starts and stops the resources as needed, you need to define only the service policies. After you define the policies, the maintenance effort for the infrastructure is low. The option to install and run multiple versions of the same application helps when you must update an existing application. Remember that the same application should not exist in two different cells. Considerations The web server plug-in enabled for Intelligent Management does not support the full range of features that are supported by an ODR server. It does not support load balancing or failover across cells, and there is no processor or memory load protection. In addition, it does not queue or reorder requests based on service policies, and does not support a highly available deployment manager topology. Setting up the topology Use the following steps to set up this topology. Setting up System A To set up System A, complete the following steps: 1. Install IBM Installation Manager. 2. Using Installation Manager, install the following applications: Web server plug-ins for WebSphere Application Server WebSphere Customization Toolbox IBM HTTP Server If you are not using IBM HTTP Server, install a supported web server. 3. Open the WebSphere Customization Toolbox, and start the Web Server Plug-ins Configuration Tool. 4. Configure the web server plug-in, and create the web server definition. For more information, see the Websphere Application Server V8.5 Information Center at: d.doc/ae/twsv_plugin.html Setting up the deployment manager (System D) To set up the deployment manager on System D, complete the following steps: 1. Install IBM Installation Manager. 2. Using Installation Manager, install WebSphere Application Server Network Deployment V8.5.5. 3. Create an application server profile: Use the app_server_root /profileTemplates/dmgr profile template. Use the app_server_root /profileTemplates/management template, and specify -serverType for DEPLOYMENT_MANAGER.
