HAManagementService (JBoss/Management API) - JBoss 4.0.1 sp1 management API Documentation 英文版文档


org.jboss.management.j2ee.cluster
Class HAManagementService

java.lang.Object
  extended byorg.jboss.mx.util.JBossNotificationBroadcasterSupport
      extended byorg.jboss.system.ServiceMBeanSupport
          extended byorg.jboss.management.j2ee.cluster.HAManagementService
All Implemented Interfaces:
HAManagementServiceMBean, javax.management.MBeanRegistration, javax.management.NotificationBroadcaster, javax.management.NotificationEmitter, org.jboss.system.Service, org.jboss.system.ServiceMBean

public class HAManagementService
extends org.jboss.system.ServiceMBeanSupport
implements HAManagementServiceMBean

This class enables a client to get a management view (JSR-77) on a JBoss Cluster. It contains the entire logic to map all the {@link org.jboss.management.j2ee.J2EEManagedObject Managed Object (MO) of all the nodes in the cluster to one MO. The same applies to State Management and Performance Statistics.

Constructor Detail

HAManagementService

public HAManagementService()
Creates a undefined clustering management service. Before this MBean can be started the HAPartition must be up and running.

ATTENTION: The current implemenation is a brute force one because it is retrieving the data on every hit. Later on this has to be resolved with a caching to avoid unecessary round-trips.
