JMS Topic: Monitoring: Durable Subscribers
Buttons Column Display Configuration Options Advanced Configuration Options Related Tasks Related Topics
Use this page to monitor and manage JMS durable subscriptions. From this page, you can view statistics for each durable subscription, as well as delete subscriptions.
Instructions: To display a list of subscriptions, first choose one or more topic members, then optionally click Advanced in order to specify filter criteria (the default filter limits reporting to the first 500 subscriptions found), and finally click Apply. To view a subscription's messages, select the check box next to its name, and then click Show Messages. To delete a subscription, select the check box next to its name, and click Delete.
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.
