Class ClusterDaemon

java.lang.Object
  org.objectweb.jonas.cluster.daemon.ClusterDaemon

All Implemented Interfaces:

ClusterDaemonMBean

public class ClusterDaemon

extends java.lang.Object

implements ClusterDaemonMBean

ClusterDaemon is provided to control JOnAS instances remotely. The ClusterDaemon is an independent Java program, and runs on every node (machine) in the cluster. It receives remote commands (JMX), and does something such as starting or stopping JOnAS instances.
