## Configuring Domains

Administrative domains provide a basic security structure whereby different administrators can administer specific groups (domains) of application server instances. By grouping the server instances into separate domains, different organizations and administrators can share a single Application Server installation. Each domain has its own configuration, log files, and application deployment areas that are independent of other domains. If the configuration is changed for one domain, the configurations of other domains are not affected.

Each Administration console session allows you to configure and manage the domain. If you have created multiple domains, you must start an additional Administration Console session to manage each domain. Each domain has its own Domain Administration Server (DAS), with a unique port number. Each administrative domain can have multiple application server instances. However, an application server instance can belong to just one domain. When the Application Server is installed, an administrative domain named `domain1` is automatically created.
