Concentrate messages to diverse locations

We can concentrate messages destined for various locations on to a single 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:

• Concentrate message traffic through a gateway
• Use 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 through 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. Other messages are put on the local queue 'QA'.

We must provide:

• Channel definitions
• Transmission queue TX1
• Remote queue definitions:
  • QA with 'QA at QMC through TX1'
  • QB with 'QB at QMD through TX1'

• Queue manager alias definition:
  • QME with 'QME through TX1'

The complementary administrator who is configuring QMC must provide:

• Receive 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.
