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.
