List non-durable subscriptions
Use this task to list the non-durable subscriptions that exist at runtime for a topic space.
The runtime state of a non-durable subscription is linked to the publication point for the messaging engine used to store messages delivered to the subscription. We can list the non-durable subscriptions by first displaying the publication point, either from the messaging engine panel or the list of all publication points for a service integration bus.
To display a list of non-durable subscriptions for a publication point, use the administrative console to complete the following steps:
Tasks
- Click Service integration -> Buses -> bus_name -> [Destination resources] Destinations. This displays any existing destinations in the content pane.
- Click the name of the topic space.
- Under Message Points, click Publication points. This displays the publication points for the topic space.
- Click the name of the publication point.
- Click the Runtime tab.
- Under Additional Properties, click Subscriptions.
The list of subscriptions for the selected topic space is displayed in the content pane. For more information about the list of subscriptions, see Subscriptions [Collection].
Each non-durable subscription is created with a has a unique subscription identifier, _NON_DURABLE_NON_SHARED<number>; and each shared non-durable subscription is created with a unique subscription identifier, clientID##subName where:
- clientID
The client identifier used to associate a connection and its objects with the messages maintained for applications (as clients of the JMS provider). We should use a naming convention that helps you identify the applications, in case we have to relate non-durable subscriptions to the associated applications for runtime administration. For more information about client identifiers, see section 6.1.2 of the JMS 2.0 specification.
- subName
- The JMS non-durable subscription name used to uniquely identify a non-durable subscription within a given client identifier. For more information about JMS non-durable subscription names, see section 8.3.1 and 8.3.2 of the JMS 2.0 specification.
What to do next
