A domain can include multiple WebLogic Server clusters and non-clustered WebLogic Server instances. A minimal domain can contain only one WebLogic Server instance, which functions both as an Administration Server, and as a Managed server—such a domain can be useful while developing applications, but is not recommended for use in a production environment. Although the scope and purpose of a domain can vary significantly, most WebLogic Server domains contain the components described in this section.
By default, the WebLogic domain created by the P6 EPPM Configuration Wizard creates a domain with an administration server (AdminServer) and a managed server for each application that you deploy.
