Determining the location of message points for a destination on a service integration bus
When you are investigating a problem, you might have to find where the message points for a destination are located.
About this task
Note: If you have an alias destination, the
alias is resolved to the physical destination immediately after a
message is produced. You can use this task to find the physical destination.
Procedure
Click Service integration -> Buses -> bus_name -> [Additional
Properties] Destinations to display the destinations on the
relevant bus. Review the Type of the destination:
- If the destination is a queue, the queue point name has the form destination@messaging_engine_name. If the queue is localized to a cluster, there is one queue point for every messaging engine in the cluster.
- If the destination is a mediated queue, there is at least one mediation point. If the queue is localized to a cluster, there is one mediation point for every messaging engine in the cluster.
- If the destination is a topic space, there is a publication point localized to every messaging engine in the bus. When a topic space is not mediated, service integration delivers messages directly to the publication point situated on the same messaging engine that the producing application is connected to. When the topic space is mediated, in the same way as a queue, service integration directs messages to the mediation point or points and then to the publication point that is co-located with that mediation point.
