Permanent topic namespaces [Collection]

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

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

• Service integration -> WS-Notification -> Services -> service_name -> Permanent topic namespaces
• Service integration -> Buses -> bus_name -> [Services] WS-Notification services -> 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 to act on, then use the buttons provided.

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

We 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:

• 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.

• 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.

• 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 an IBM MQ network.

When we create 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.
