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.

Decide which method to use to configure these resources. We can show the properties of a permanent WS-Notification topic namespace using the dmgr console as described in this task, or using the showWSNTopicNamespace command. A permanent topic namespace has the following characteristics:

When creating a new WS-Notification permanent topic namespace, we 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. We 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 dmgr console to complete the following steps:

  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 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 associated with a given permanent topic namespace, click the link in the Namespace documents column.

    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.
