Red Hat JBoss Enterprise Application Platform Administration I

A Red Hat JBoss Enterprise Application Platform (JBoss EAP) managed domain is made up of one domain or primary controller, and one or more host controllers, server groups, and servers.

Configure the server groups at the domain controller level, in the domain.xml file. Configure the servers at the host controller level, in the host.xml file.

A managed domain can have any number of servers and server groups. A server belongs only to a server group.

You can configure the host controllers to run any number of servers, if the host has the hardware capacity to run the server instances.

You must deploy applications only to server groups.

You can configure and manage server groups and servers by using the JBoss EAP management console or the management CLI. Both tools automatically update the underlying domain.xml and host.xml files.

If you configure multiple servers on the same host, then you must use port offsets to avoid network port collisions.

A server group is associated with a profile. The profile defines the subsystems, configuration, and network sockets that a server group uses.
