What Is a Domain?
A domain is the basic administration unit for WebLogic Server instances. A domain
consists of one or more WebLogic Server instances (and their associated resources)
that you manage with a single Administration Server. You can define multiple
domains based on different system administrators’ responsibilities, application
boundaries, or geographical locations of servers. Conversely, you can use a single
domain to centralize all WebLogic Server administration activities.
If you create multiple domains, keep in mind that each domain is represented in a
separate configuration file (
config.xml), and you cannot perform configuration or
deployment tasks in multiple domains at the same time. When you use the
Administration Console to perform a configuration task, the changes you make apply
to the currently selected domain. To make changes in a different domain, you must
select that domain. For this reason, the servers instances, applications, and resources
in one domain should be treated as being independent of servers, applications, and
resources in a different domain.
