Use this task to delete, from a service integration bus, a topic space.
Before we can delete a topic space, ensure the publication points are empty. A delete action is rejected if there are any indoubt or uncommitted publications for a publication point.
Any attached producers are closed asynchronously, and do not prevent the delete action. However, any messages sent after the delete action, but before close of producers are discarded.
The service integration bus topic space is the primary messaging object upon which WS-Notification depends at run time. For information about the effect that deleting a topic space has upon new and existing WS-Notification applications, see Failures as a result of changes in topic space and topic namespace configurations. To delete a topic space, use the dmgr console to complete the following steps.
- Click Service integration -> Buses -> bus_name -> [Destination resources] Destinations.
- Select the check box next to the destination name.
- Check for and resolve any undelivered publications (indoubt or uncommitted) for the topic space. Messages that are locked, as part of in-flight transactions or as indoubt messages, are not deleted.
- To delete the empty topic space, click Delete.
- To confirm to delete the topic space, click OK.
- Save your changes to the master configuration.
Results
The topic space is deleted.
