Configuring JMS activation specification properties for durable subscriptions

Use this task to configure durable subscription properties of JMS activation specifications for use by message-driven beans with the default messaging provider.

Why and when to perform this task

To enable a message-driven bean (MDB) application to create durable subscriptions on JMS topics with the default messaging provider, you set a number of properties on the JMS activation specification used by the application.

If applications use message-driven beans to create durable subscriptions, you should set the properties on the JMS activation specification used by the message-driven beans, as described in this topic. Otherwise, for enterprise beans to create durable subscriptions, you should set the properties on the JMS connection factory as described in Configuring JMS connection factory properties for durable subscriptions.

To configure the durable subscription properties to a topic for use by message-driven beans with the default messaging provider, use the administrative console to complete the following steps

Steps for this task

  1. Display the default messaging provider. In the navigation pane, click Resources > JMS providers > Default messaging provider. This displays in the content pane a table of properties for the default messaging provider, including links to the types of JMS resources that it provides.
  2. Optional: Change the Scope check box to set the level at which the connection factory is to be visible, according to your needs.
  3. In the content pane, under the Activation specifications heading, click JMS activation specification. This displays any existing JMS activation specifications for the default messaging provider in the content pane.
  4. Click the name of the activation specification you want to configure. This displays the properties for the activation specification in the content pane.
  5. Specify the following properties for the activation specification:.
    Client identifier
    This is the JMS client identifier that applications need to identify durable topic subscriptions created on all connections using this activation specification. For more information about client identifiers, see section 4.3.2 of the JMS 1.1 specification.
    Durable subscription home
    The name of the messaging engine used to store messages delivered to durable subscriptions for objects created from this JMS activationSpec. Required field when using a durable topic subscription.

    This identifies the messaging engine where durable subscriptions are localized on the service integration bus. Administrators can manage the runtime state of durable subscriptions through publication points for that messaging engine.

    Subscription durability
    To be able to create durable subscriptions, set this property to Durable.
    Subscription name
    The subscription name needed for durable topic subscriptions. Required field when using a durable topic subscription.

    Each JMS durable subscription is identified by a subscription name (specified on this property). A JMS connection also has an associated client identifier (specified on the Client identifier property), which is used to associate a connection and its objects with the list of messages (on the durable subscription) that is maintained by the JMS provider for the client.

    This subscription name must be unique within a given client identifier.

  6. Specify the properties for the activation specification, according to your needs.
  7. Click OK.
  8. Save your changes to the master configuration.
When applications have created durable subscriptions, you can use the administrative console to manage the runtime state of those subscriptions, as described in Administering durable subscriptions.
