Open Queue Handles workspace

Use the Open Queue Handles workspace to help you determine which applications or users opened which queues, and for what purpose.

Important: The data contained within this workspace is collected on-request-only, not during the standard sampling interval. Each time you open, link to, or refresh this workspace, the monitoring agent queries MQ and collects the requested data. Therefore, for performance reasons, this workspace should not be placed in a short interval automatic refresh mode.

To access this workspace, select the Queue Statistics item for the selected queue manager within the Navigator physical view and right-click, and click Workspace > Open Queue Handles from the menu.

Predefined views

The Open Queue Handles workspace includes the following predefined views:

  • Open Queue Handles Use this view to help you determine which applications or users opened which queues, and for what purpose.

    The Open Queue Handles view contains detailed application-related information, including the reasons why queues were opened, for a selected queue manager. This table contains one row for each open queue handle, so if a queue has no open handles, the table will be empty. You can also use this table to view status information for a particular queue.

  • Message Log The message log gives you an overview of changes in the status of your monitored system. It also provides information about the status of monitoring agents and other system events. For more information on this view, see Tivoli® Enterprise Portal Help.

For more information on the attributes listed in the tables of this workspace, see Queue Handle Status attributes.
