Installation scenarios

You can install WebSphere® Extended Deployment, including all three separate products, in various ways to enhance your application server environment. Depending on your existing environment and which product you install, the installation process includes certain features that might not be available in other installation scenarios.

This topic provides common installation scenarios for the product. The installation scenarios include descriptions to help you determine what components to install for a given topology. For optimal quality of service and extended manageability, review the scenarios to determine which topology best fits your needs.

WebSphere Extended Deployment Version 6.1.1 includes the following three products:

You can install WebSphere Extended Deployment Compute Grid in an environment that contains existing installations of WebSphere Application Server Network Deployment and either WebSphere Virtual Enterprise, WebSphere eXtreme Scale, or both. During installation, the product automatically identifies the WebSphere Application Server Network Deployment installation and extends the functionality to embrace the themes and added function of the product. As a result, the job scheduler is installed. If your environment contains Virtual Enterprise, you can add Compute Grid to the centralized installation manager repository, and then use the centralized installation manager to install your added component from the repository to the nodes.

When you install Compute Grid in environments in which Virtual Enterprise does not exist, the wizard does not present the option to add the product to the centralized installation manager repository. However, you can add the product later by using the centralized installation manager repository tool. See Using the centralized installation manager repository tool to add products for more information.

Also, the middleware agent is installed on a node that is running other middleware servers, such as Tomcat or PHP, when you install Compute Grid in other server environments. The middleware agent is a server process that is used to manage servers that are not running the product.

When you integrate eXtreme Scale with an existing installation of WebSphere Application Server Network Deployment, Virtual Enterprise, and Compute Grid, you can install both the eXtreme Scale client and server, or you can install the client only. See the WebSphere eXtreme Scale Information Center for more information.
