Destination mediation
A destination can be configured with one or more mediations that refine how messages are handled by the destination. 例如,調解可以修改實際的訊息,或將訊息重新導向至另一個目的地或目的地序列,或兩者。
A mediation can process messages through message transformation, subsetting, aggregation, disaggregation, and using a selection of destinations (but not consumers) to which the message can be forwarded.
When a message arrives at the mediation point, the mediation consumes the message and can transform, subset, aggregate or disaggregate the message. The message is then either forwarded to another destination or returned to the same destination. If the message is returned to the same destination, it goes to the queue point, where it can be consumed by the messaging application. This process is shown in the following figure:

You can configure a destination so the mediation point or the queue point, or both are IBM MQ queues. If both are IBM MQ queues then a IBM MQ application can act as an external mediation as shown in the following figure:
