Overview

domain.xml is the main configuration file for a managed domain, containing various profiles to be pushed to different servers belonging to the server groups managed by the domain. Only the domain master reads this file. RedHat documentation mentions that domain.xml can be removed on other domain members. However, it should not be removed from the backup domain controller, if the domain is configured to support HA. For more details see subordinate host controller post-install configuration - optionally remove domain.xml. The file's location is $JBOSS_HOME/domain/configuration/domain.xml.

Sections

<server-group>

The <server-group> section defines the server groups for this management domain.

The server group configuration specifies the following mandatory attributes:

  • the name of the server group
  • the server group profile
  • the socket binding group for the servers in the group. This value can be overridden in host.xml.

It also can specify optional elements:

<jvm>

<jvm> is an optional element. It can be used to specify the following configuration for the JVMs running server nodes belonging to this server group:

<heap>

<heap>

<system-properties>

<system-properties> is an optional element.

<deployments>

<deployments> is an optional element.

For more on deployments, see domain mode deployments.
