Concentrating messages to diverse locations

 

Figure 1. Combining message flows on to a channel

Figure 1 illustrates a distributed-queuing technique for concentrating messages that are destined for various locations on to one channel. Two possible uses would be:

• Concentrating message traffic through a gateway

• Using wide bandwidth highways between nodes

In this example, messages from different sources, local and adjacent, and having different destination queues and queue managers, are flowed via transmission queue ‘TX1’ to queue manager QMC. Queue manager QMC delivers the messages according to the destinations, one set to a transmission queue ‘QMD’ for onward transmission to queue manager QMD, another set to a transmission queue ‘QME’ for onward transmission to queue manager QME, while other messages are put on the local queue ‘QA’.

You must provide:

• Channel definitions

• Transmission queue TX1

• Remote queue definitions:

  • QA with ‘QA at QMC via TX1’

  • QB with ‘QB at QMD via TX1’

• Queue manager alias definition:

  • QME with ‘QME via TX1’

The complementary administrator who is configuring QMC must provide:

• Receiving channel definition with the same channel name

• Transmission queue QMD with associated sending channel definition

• Transmission queue QME with associated sending channel definition

• Local queue object QA.
