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.

[Version 6.0.2] 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.

[Version 6.0.2] By monitoring message points and remote message points, you can fully analyze and resolve problems arising from distributed application messaging. For example, you can:
