JMS Topic: Monitoring: Durable Subscribers
Buttons Column Display Related Tasks Related Topics
Use this page to monitor and manage durable subscribers that are running on a JMS topic. From this page, you can view detailed runtime statistics for each durable subscriber, as well as create new durable subscribers or delete existing ones.
Click on a subscriber to view its configuration details. To view a subscriber's messages, select the check box next to its name, and then click the Show Messages button.
Durable subscribers are persisted to a disk-based file store or a JDBC-accessible database until the message has been delivered to the subscribers or has expired, even if those subscribers are not active when the message is delivered. A durable subscriber registers a durable subscription with a unique identity that is retained by JMS. Subsequent subscriber objects with the same identity resume the subscription in the state it was left by the prior subscriber. If there is no active subscriber for a durable subscription, JMS retains the subscription's messages until they are received by the subscription or until they expire.
