2 Overview of WebLogic Server Domains
2-2 Configuring and Managing WebLogic Server
Contents of a Domain
A domain can include multiple WebLogic Server clusters and non-clustered
WebLogic Server instances. Strictly speaking, a domain could consist of only one
WebLogic Server instance—however, in that case that sole server instance would be
an Administration Server, because each domain must have exactly one Administration
Server. Although the scope and purpose of a domain can vary significantly, most
WebLogic Server domains contain the components described in this section.
The following figure shows a production environment that contains an Administration
Server, three standalone Managed Servers, and a cluster of three Managed Servers.
