About Durable and Non-Durable Subscribers
When a JMS trigger receives messages from a topic, you can specify whether or not the JMS trigger is a durable subscriber.
A durable subscriber establishes a durable subscription with a unique identity on the JMS provider. A durable subscription allows subscribers to receive all the messages published on a topic, including those published while the subscriber is inactive (for example, if the JMS trigger is disabled). When the associated JMS trigger is disabled, the JMS provider holds the messages in guaranteed storage. If a durable subscription already exists for the specified durable subscriber on the JMS provider, this service resumes the subscription.
A non-durable subscription allows subscribers to receive messages on their chosen topic only if the messages are published while the subscriber is active. A non-durable subscription lasts the lifetime of its message consumer. Note that non-durable subscribers cannot receive messages in a load-balanced fashion.
