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.
You can install WebSphere eXtreme Scale in an environment that contains existing installations of WebSphere Application Server Network Deployment and either WebSphere Virtual Enterprise, WebSphere Extended Deployment Compute Grid, or both. During the installation process, the wizard detects and verifies the existing installations as part of the current process. As a result, the ObjectGrid component and the partitioning facility (WPF) are installed. If your environment contains WebSphere Application Server Network Deployment and Virtual Enterprise, you can add eXtreme Scale to the centralized installation manager repository, which you can later use to shorten the number of steps that are required to create and manage your remote environments.
When you install eXtreme Scale in environments in which WebSphere Application Server Network Deployment or Virtual Enterprise do not exist, the middleware agent is installed on a node that is running other middleware servers. The middleware agent is a server process that is used to manage other middleware servers. See Middleware agent for more information.
Additionally, the wizard does not provide the option to add the product to the centralized installation manager repository when you are installing in other server environments. 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.
Starting with WebSphere eXtreme Scale Version 6.1.0.3,
you can install stand-alone ObjectGrid in an environment
that does not contain WebSphere Application Server
Network Deployment.
