Permanent topic namespaces [Collection]

A topic namespace is a grouping of topics that allows information to be shared between applications.

To view this pane in the console, click one of the following paths:

  • Service integration > Web services > WS-Notification services > [Content Pane] service_name > Permanent topic namespaces
  • Service integration > Buses > [Content Pane] bus_name > [Services] WS-Notification services > [Content Pane] service_name > Permanent topic namespaces

To browse or change the properties of a listed item, select its name in the list.

To act on one or more of the listed items, select the check boxes next to the names of the items that you want to act on, then use the buttons provided.

To change which entries are listed, or to change the level of detail that is displayed for those entries, use the Filter settings.

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.

A permanent topic namespace has the following characteristics:
  • It enables you 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.
  • It allows you to restrict the structure and content of the topic namespace by applying one or more topic namespace documents that describe the required structure.
  • It allows the topic namespace to be used 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 permanent WS-Notification 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.
