Showing the properties of a permanent WS-Notification topic namespace

A topic namespace is a grouping of topics that allows information to be shared between applications. You use a permanent topic namespace to statically define the association between a WS-Notification topic namespace URI and a service integration bus topic space destination.

Before you begin

Decide which method to use to configure these resources. You can show the properties of a permanent WS-Notification topic namespace by using the administrative console as described in this task, or by using the showWSNTopicNamespace command.

About this task

A permanent topic namespace has the following characteristics:
  • You can use it to expose an existing service integration bus topic space for use by WS-Notification clients, thus permitting interoperation between the WS-Notification applications and existing publish and subscribe applications connected to the bus such as JMS.
  • You can use it to restrict the structure and content of the topic namespace by applying one or more topic namespace documents that describe the required structure.
  • You can use it as part of a topic space mapping configured on a service integration bus link (between two service integration buses) or a topic mapping as part of a publish and subscribe bridge between a service integration bus and a WebSphere® MQ network.

When you create a new WS-Notification permanent topic namespace, you specify the namespace and associate it with one of the service integration bus topic spaces configured on the bus on which the parent WS-Notification service is defined. You cannot modify a permanent topic namespace after it has been created, other than to apply or remove topic namespace documents.

To show the properties of a permanent WS-Notification topic namespace, use the administrative console to complete the following steps:

Procedure

  1. In the navigation pane, click Service integration -> WS-Notification -> Services -> service_name -> Permanent topic namespaces or Service integration -> Buses -> bus_name -> [Services] WS-Notification services -> service_name -> Permanent topic namespaces . The Permanent topic namespaces [Collection] form is displayed. This form shows all the permanent topic namespaces configured for this WS-Notification service.
  2. Optional: To view the configuration of the service integration bus topic space that is associated with a given permanent topic namespace, click the link in the Service integration bus topic space column. For more information, see Topic space [Settings]
  3. Optional: To view the configuration of the namespace documents that are associated with a given permanent topic namespace, click the link in the Namespace documents column.
    Note: This link also shows the number of namespace documents (0 or more) that are currently applied.
    The Topic namespace document [Collection] form is displayed. Use this form to apply, show or delete topic namespace documents.
