To define your database configuration, you must use the database design tool to define the configuration and to save the settings to a database design file. You can run the database design tool in a UNIX System Services shell either before or after you create the default profile in the configuration file system.
The configuration file system contains various application server root directories and associated symbolic links. Each node has its own application server root directory, which is referred to as the WAS_HOME directory; for example, /WebSphere/V8R0/AppServer for a stand-alone server or empty node, or /WebSphere/V8R0/DeploymentManager for a deployment manager node.
