Managing TIBCO EMS queues

Queues are an integral part of any messaging system, whether associated with IBM WebSphere MQ or TIBCO EMS.

Select Queues from the Navigation Panel, and all queues belonging to the TIBCO EMS server are displayed in the Queues Summary View. 

This is a critical view, given the role of queues within any messaging system.

Available operations include the following:

• Copy As New Queue: Copies the selected queue. See also Creating a queue below.
• Purge: Purge the queue of data.
• Delete: Delete the queue from the server.
• Put Messages: Displays the Message dialog to define new messages (choose from one of these formats: Text Message, Bytes Stream or Message) to place in the queue.
• Upload/Import Messages: Displays the Upload dialog, to upload a message that was saved to a file, and import it into the queue. You can upload three types of file: an MVMA Message File, a File as a Single Message, or a File as Multiple Messages (which need to be separated on a new line per message).
• Copy Messages: Displays the Copy Message dialog for copying messages from one queue to another queue on the same TIBCO EMS Server.
• Move Messages: Displays the Move Message dialog for moving messages from one queue to another queue on the same TIBCO EMS Server.
• Find Messages: Displays the Search Details dialog in which you can search for specific messages. Appropriate Message Headers are included in the drop-down for Tibco EMS.
• Permissions: View, edit, create or delete object permissions on a per-principal (user or group) basis for the selected queue. See also Viewing object permissions below.
• Tag Queue: Associate the queue with a tag.
• Audit: View related audit records, including user-set parameters.

To access the selected queue's Properties Editor, click on the Queue Name.
