Interface AdminService


  • public interface AdminService
    The AdminService is the server-side interface to the WebSphere v5.0 administration functions. It exposes the public admin APIs to any code running in the server JVM. Many of the AdminService methods are also available from remote JVMs through use of the AdminClient interface. Other methods are only accessible from the same JVM as the AdminService instance.

    In order to obtain a reference to the singleton AdminService instance, use the static method getAdminService() of the AdminServiceFactory class.

    Many of the methods defined on the AdminService interface come from the JMX MBeanServer interface. The WebSphere AdminService extends the standard JMX MBeanServer function with distributed system support and enhanced security. The regular JMX MBeanServer is accessible in WebSphere JVMs from the getMBeanServer() method of the MBeanFactory interface.

    Code that runs in the same JVM as the AdminService must also have the required Java 2 Security permissions in order to successfully invoke any of the AdminService methods. In order to obtain a reference to the AdminService in the first place, code must have at least the following permission:

    • com.ibm.websphere.management.AdminPermission "getAdminService"

    Other permissions that it may be necessary for code to be granted before it can call certain AdminService methods include:

    • com.ibm.websphere.management.AdminPermission "getMBeanFactory"
    • com.tivoli.jmx.MBeanServerPermission "MBeanServerFactory.*"
    • com.tivoli.jmx.MBeanServerPermission "MBeanServer.*"
    where the individual target names are: 
        MBeanServer.addNotificationListener 
    MBeanServer.createMBean 
    MBeanServer.deserialize 
    MBeanServer.getAttribute 
    MBeanServer.getDefaultDomain 
    MBeanServer.getMBeanCount 
    MBeanServer.getMBeanInfo 
    MBeanServer.getObjectInstance 
    MBeanServer.instantiate 
    MBeanServer.invoke

      • addNotificationListenerExtended

        void addNotificationListenerExtended(javax.management.ObjectName name,
                                   javax.management.NotificationListener listener,
                                   javax.management.NotificationFilter filter,
                                   java.lang.Object handback)
        Adds a listener to multiple MBeans. Behaves similarly to the addNotificationListener(javax.management.ObjectName, javax.management.NotificationListener, javax.management.NotificationFilter, java.lang.Object) method, except for the following:
        • The name parameter may include wildcards, and pattern matching is performed as in the queryMBeans method; null is not allowed
        • Listeners added with this method will receive notifications by MBeans registered in the future; i.e. the MBean does not need to be active currently to listen to it.
        • An InstanceNotFoundException is never thrown.
        Parameters:
        name - a pattern matching zero or more MBeans; notifications from all these MBeans will be routed to the listener
        listener - the listener object which will handle the notifications emitted by the registered MBean
        filter - the filter object; if filter is null, no filtering will be performed before handling notifications
        handback - the context to be sent to the listener when a notification is emitted
        Throws:
        ConnectorException - a communication problem occured adding the listener

      • removeNotificationListener

        void removeNotificationListener(javax.management.ObjectName name,
                              javax.management.NotificationListener listener)
                                throws javax.management.InstanceNotFoundException,
                                       javax.management.ListenerNotFoundException
        Removes a listener from exactly one MBean. Behaves identically to the JMX MBeanServer.removeNotificationListener, except that it works in a distributed environment. This means that MBeans which are not located on this specific process may have listeners added to it assuming routing information is correct.

        This method should not be used to remove listeners added with addNotificationListenerExtended(javax.management.ObjectName, javax.management.NotificationListener, javax.management.NotificationFilter, java.lang.Object); use removeNotificationListenerExtended(ObjectName,NotificationListener) instead.

        Parameters:
        name - the name of the MBean on which the listener should be removed
        listener - the listener object which will handle the notifications emitted by the registered MBean
        Throws:
        javax.management.InstanceNotFoundException - the MBean name provided does not match any of the registered MBeans
        javax.management.ListenerNotFoundException - the listener is not registered in the MBean
        ConnectorException - a communication problem occured adding the listener

      • getObjectInstance

        javax.management.ObjectInstance getObjectInstance(javax.management.ObjectName name)
                                                  throws javax.management.InstanceNotFoundException
        Gets the ObjectInstance for a given MBean registered with the MBean server.
        Parameters:
        name - the object name of the MBean.
        Returns:
        the ObjectInstance associated with the MBean specified by name. The contained ObjectName is name and the contained class name is getMBeanInfo(name).getClassName().
        Throws:
        javax.management.InstanceNotFoundException

      • addNotificationListener

        void addNotificationListener(javax.management.ObjectName name,
                           javax.management.ObjectName listener,
                           javax.management.NotificationFilter filter,
                           java.lang.Object handback)
                             throws javax.management.InstanceNotFoundException
        Adds a listener to a registered MBean. A notification emitted by an MBean will be forwarded by the MBeanServer to the listener. If the source of the notification is a reference to an MBean object, the MBean server will replace it by that MBean's ObjectName. Otherwise the source is unchanged.

        The listener object that receives notifications is the one that is registered with the given name at the time this method is called. Even if it is subsequently unregistered, it will continue to receive notifications.

        Parameters:
        name - the name of the MBean on which the listener should be added.
        listener - the listener object which will handle the notifications emitted by the registered MBean.
        filter - the filter object; if filter is null, no filtering will be performed before handling notifications.
        handback - the context to be sent to the listener when a notification is emitted.
        Throws:
        javax.management.InstanceNotFoundException - the MBean name provided does not match any of the registered MBeans.

      • removeNotificationListener

        void removeNotificationListener(javax.management.ObjectName name,
                              javax.management.NotificationListener listener,
                              javax.management.NotificationFilter filter,
                              java.lang.Object handback)
                                throws javax.management.InstanceNotFoundException,
                                       javax.management.ListenerNotFoundException
        Removes a listener from a registered MBean. The MBean must have a listener that exactly matches the given listener, filter, and handback parameters. If there is more than one such listener, only one is removed.

        The filter and handback parameters may be null if and only if they are null in a listener to be removed.

        Parameters:
        name - the name of the MBean on which the listener should be removed.
        listener - the listener that was previously added to this MBean.
        filter - the filter that was specified when the listener was added.
        handback - the handback that was specified when the listener was added.
        Throws:
        javax.management.InstanceNotFoundException - the MBean name provided does not match any of the registered MBeans.
        javax.management.ListenerNotFoundException - the listener is not registered in the MBean, or it is not registered with the given filter and handback.

      • removeNotificationListener

                                       javax.management.ListenerNotFoundException
        Removes a listener from a registered MBean. If the listener is registered more than once, perhaps with different filters or callbacks, this method will remove all those registrations.
        Parameters:
        name - the name of the MBean on which the listener should be removed.
        listener - the object name of the listener to be removed.
        Throws:
        javax.management.InstanceNotFoundException - the MBean name provided does not match any of the registered MBeans.
        javax.management.ListenerNotFoundException - the listener is not registered in the MBean.
