Configuring a Version 7.0 WS-Notification service with Web service QoS

Use administrative console to configure web service qualities of service (QoS) such as reliability or security by applying policy sets to a Version 7.0 WS-Notification service. The configuration of policy sets for WS-Notification can be split into two types: service provider (for Version 7.0 WS-Notification service points) and service client (for Version 7.0 WS-Notification service clients). Policy set configuration for these two elements of a WS-Notification service is handled differently.

WebSphere Application Server offers two WS-Notification service and service point options: the JAX-WS based Version 7.0 option and the JAX-RPC based Version 6.1 option. This task assumes that we have already designed a server topology for web service qualities of service for WS-Notification and created a Version 7.0 WS-Notification service. We must also have configured policy sets that meet the quality of service requirements. We can reuse existing policy sets within the organization, use the default policy sets provided by WebSphere Application Server, or create new policy sets. For more information, see Manage policy sets using the administrative console.


Version 7.0 WS-Notification service points (NotificationBrokers, PublisherRegistrationManagers and SubscriptionManagers) are implemented as JAX-WS applications that are deployed to servers or clusters, and the management of the policy sets for these WS-Notification service points is configured using the policy set administrative infrastructure for service providers (both panels and wsadmin commands). In the Service provider [settings] panel for a WS-Notification service provider, there is a link to the associated WS-Notification service point application. Use the service provider settings panel to attach policy sets to each NotificationBroker, PublisherRegistrationManager and SubscriptionManager.


Version 7.0 WS-Notification services are implemented as two configurable service clients (OutboundNotificationService and OutboundRemotePublisherService) for each WS-Notification service. Events that need outgoing web service invocations occur at the service integration bus level rather than the bus member level, even though notifications of the events occur within a particular bus member. The two service clients that a WS-Notification service implements are therefore configured using the policy set administrative infrastructure for service clients. In the Service client policy sets and bindings [collection] panel, the two service clients for a given WS-Notification service are listed in a tree structure, along with their endpoints and operations. Use this panel to attach policy sets to each service client, or to both service clients for the WS-Notification service.

  1. Start the administrative console.

  2. Navigate to Service integration -> WS-Notification -> Services or Service integration -> Buses -> bus_name -> [Services] WS-Notification services. The WS-Notification services [Collection] form is displayed.

  3. In the content pane, click the name of the Version 7.0 WS-Notification service to which to apply web service qualities of service. The current settings for this Version 7.0 WS-Notification service are displayed in the WS-Notification services [Settings] panel.

  4. Optional: To configure web service QoS for inbound requests, apply policy sets to the service provider applications (NotificationBroker, PublisherRegistrationManager and SubscriptionManager) associated with a service point:

    Click [Additional Properties] WS-Notification service points. The WS-Notification service points [Collection] form is displayed. This form shows all the service points configured for this Version 7.0 WS-Notification service.

    Repeat the following steps, as required, to configure the policy set and binding information for one or more service provider applications for one or more service points:

    1. In the content pane, click the name of a Version 7.0 WS-Notification service point in the list. The current settings for this Version 7.0 WS-Notification service point are displayed in the WS-Notification service points [Settings] form.

    2. Click [Additional Properties] Policy set configuration. A link to each of the service provider applications (NotificationBroker, PublisherRegistrationManager and SubscriptionManager) for this service point is displayed in the Service provider [Collection] form.

    3. Click the name of one of the applications. An indented list of endpoints and operations for this service is displayed in the Service provider [settings] form.

    4. Select one or more items in the list (service, endpoint or operations), then perform one of the three available operations on the items we have selected:

      For more information, see Manage policy sets using the administrative console.

    5. Restart the service provider application.

  5. Optional: To configure web service QoS for outbound requests, apply policy sets to one or both of the web service clients associated with the WS-Notification service:

    1. If necessary, navigate back to the WS-Notification services [Settings] panel for this Version 7.0 WS-Notification service.

    2. Click [Additional Properties] Outbound request policy sets and bindings. The two service clients for this WS-Notification service are listed in a tree structure, along with their endpoints and operations, in the Service client policy set and bindings [collection] form.

    3. Select one or both service clients, then perform one of the three available operations on the items we have selected:

      • Attach client policy set

      • Detach client policy set

      • Assign binding

      For WS-Notification service clients, policy set attachments are not supported at the endpoint (port) or operation level. Therefore endpoints or operations are not selectable, and are shown as inheriting any policy set or binding that is attached to the service client. For more information, see Manage policy sets using the administrative console.

      Use the Service client policy set and bindings [collection] form, we can configure the policy set and binding information for both service clients for the selected service. Alternatively, we can configure the policy set and binding information for a single Version 7.0 WS-Notification service client by clicking Services -> Service clients -> ws-notification_service_client_name and using the WS-Notification service client [settings] panel. This panel also provides links to the associated service integration bus and WS-Notification service.
