Messaging
This view shows the status details for the messaging infrastructure that is used to process outgoing transmissions.
The messaging infrastructure uses IBM® MQ for asynchronous communication by external applications, such as the Transaction Server, and internally by the Distribution engine for concurrent processing.
The messaging view shows the basic health of the messaging definitions that are needed for asynchronous processing. If a messaging definition is not available or is identified as having a potential problem, its entry is highlighted.
The following information is shown for each entry.
- Queue
- Name of the messaging queue that is needed for asynchronous processing.
- Messages
- Total number of messages that are waiting to be processed. If the total number of messages reaches certain
limits, the messaging entry is highlighted as follows:
- Yellow
- The entry is highlighted yellow if the total number of messages reaches, or exceeds, the value specified in the warning threshold user interface property. This highlighting indicates that messages are backing up on the Distribution engine input queue.
- Red
- The entry is highlighted red if the total number of messages reaches, or exceeds, the value specified in the critical threshold user interface property. This highlighting indicates that the messaging load is too high for the Distribution engine to process in a timely manner.
- Status
- The connectivity status. Valid values are active or unavailable. If a component is not available, the entry in the view is highlighted red.
The following table shows the entries for this view.
| Name | Description |
|---|---|
| Distribution Queue | This entry represents the status of the queue that is defined for sending asynchronous requests into the Distribution engine for processing. Examples of these requests might be Transaction Server posting transactions that are ready for outbound processing. Or, the Distribution user interface batch (ICL) processing requests for building segments. |
| Transmission Queue | This entry represents the status of the queue that is defined for internal transmission processing. |
| Segment Queue | This entry represents the status of the queue that is defined for internal segment processing. |
