The "all" server configuration file set is located in the JBOSS_DIST/jboss-as/server/all directory. In addition to the services in the "default" set, the all configuration contains several other services in the conf/ directory as shown below.
This service configures clustering communication for most clustered services in JBoss.
This provides the HA singleton service, allowing JBoss to manage services that must be active on only one node of a cluster.
farm-service.xml provides the farm service, which allows for cluster-wide deployment and undeployment of services.
