Message points

A message point is associated with a messaging engine and holds messages for a bus destination.

A message point is the general term for the location on a messaging engine where messages are held for a bus destination. A message point can be:

For point-to-point messaging, the administrator selects one bus member, which can be an application server or server cluster, to hold the messages of the queue destination. This action automatically defines a queue point for each messaging engine in the assigned bus member.

For publish/subscribe messaging, the administrator configures a topic space destination, but does not need to assign a bus member for the topic space. A topic space has a publication point defined automatically for each messaging engine in the bus.

Message points can be remote from the application which is producing to or consuming from the bus destination. In other words, message points can reside on a messaging engine other than the messaging engine to which the application is connected. In this situation the message point is represented at runtime by a remote message point on the remote messaging engine.

By monitoring message points and remote message points, you can fully analyze and resolve problems arising from distributed application messaging. For example, you can:
