Viewing and deleting messages in a JMS queue

You can view a list of the messages in a JMS queues, download these messages to view their content, and you can delete messages from configured queues. When viewing or deleting messages, you can apply a selector to limit the messages returned for processing.

About this task

Messages that are currently being processed to a continuous queue by a message-driven bean or to a sequential queue by a JMS cron task are not available to view or delete. You can deactivate the cron task to stop the processing of messages to a sequential queue. Message-driven beans continually process messages and the number of messages being processed can vary. Unless you disable message-driven beans, it is likely that not all messages can be viewed or deleted. If you view or delete messages while message-driven beans are enabled, it is possible that not all messages are available for processing.

Procedure

  1. In the External Systems application, select the Add/Modify Queues action .
  2. Select a queue, and click either the View Queue Data button or the Delete Queue Data button.

  4. Optional: Specify one of the following selectors if you want to filter the records returned in either the View Queue Data window or in the Delete Queue Data window:
    Option Description

    destination The name of the external system for outbound queues only.
    SENDER The name of the external system for inbound messages only.
