Domain Administration Server

Domain Administration Server (DAS) is an integral concept of Sun Java System Application Server 8.1. Installing the J2EE agent on Sun Java System Application Server 8.1 while not understanding the DAS concept can lead to complications. The following cautionary note describes one potential complication that can arise.

---

Caution –

Once a J2EE agent is installed for a specific domain, the J2EE agent binaries cannot be used on that same host for a different Sun Java System Application Server 8.1 domain. If you attempt to use previously installed J2EE agent binaries on the same host, but on a different domain, the installation fails. For more information, see Installing a J2EE Agent for a Sun Java System Application Server 8.1 Instance on a Different Server Domain.

To protect content on Sun Java System Application Server 8.1 using an agent, you need to understand DAS. The following is a brief description of administrative domains and how they pertain to DAS.

Administrative domains provide a basic security structure whereby different administrators can administer specific groups (domains) of Sun Java System Application Server 8.1 instances. By grouping the server instances into separate domains, different organizations and administrators can share a single Sun Java System Application Server 8.1 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 domain has its own DAS, with a unique port number.

For more information on DAS and administrative domains, see the Sun Java System Application Server 8.1 Administration Guide.
