weblogic.cluster.singleton
Class MigratableServerService

java.lang.Object
  weblogic.server.AbstractServerService
      weblogic.cluster.singleton.MigratableServerService

All Implemented Interfaces:

PropertyChangeListener, EventListener, LeaseLostListener, LeaseObtainedListener, weblogic.management.runtime.ServerStates, weblogic.server.ServerService

public class MigratableServerService
extends weblogic.server.AbstractServerService
implements LeaseLostListener, PropertyChangeListener, LeaseObtainedListener

MigratableServerService registers ServerMigrationCoordinator with the MBean server and creates the ClusterMaster Leasing implementation. Health is proved every ClusterMBean.getHealthCheckIntervalMillis() ms (default 10s), and if health could not be proved for ClusterMBean.getHealthCheckPeriodsUntilFencing() (default 3) mastership is abdicated.
