Managing Durable Subscriptions 

Use

When the message producer is no longer active, messages that were sent can be lost. If you create a durable subscriber, the message will not be lost in such a case.

Using durable subscriptions may lead to higher overheads. A durable subscription can have only one active subscriber at a time.

Procedure

...

       1.      Create a durable subscription:

... Topic topic; String subscription_name = “my_sub”; ... TopicSubscriber topicSubscriber = topicSession.createDurableSubscriber(topic, subscription_name);

       2.      Stop the durable subscription:

topicSubscriber.close();

       3.      Delete the durable subscription. Unsubscribe the subscription name:

topicSession.unsubscribe(subscription_name);
