Mediation points

A mediation point is a location in a messaging engine at which messages are stored and mediated.

mediation points

A mediation point is a specialized message point. When an administrator mediates a destination, one or more mediation points are created on the bus member, depending on the type of destination. For a mediated queue (used in point-to-point messaging), a mediation point is created for each queue point on the bus member. For a mediated topic space (used in publish/subscribe messaging), a mediation point is created for each publication point on the bus member.

Mediations are operated at mediation points. The run time state of a mediation point represents a run time instance of the mediation. The administrator uses the administrative console to start and stop mediations at mediation points on specific destinations. For example, if the administrator starts a mediation at a selected mediation point, messages sent to the destination are processed immediately by the mediation. If the administrator stops a mediation, messages arriving at the destination are held at the mediation point until the mediation is restarted.

The administrator can also control how messages are sent to and received from destinations by configuring mediation point properties in the administrative console. These properties override properties set for the destination:
