Message channel planning example for z/OS

This section provides a detailed example of how to connect z/OS or MVS queue managers together so that messages can be sent between them.

The example illustrates the preparations needed to allow an application using queue manager QM1 to put messages on a queue at queue manager QM2. An application running on QM2 can retrieve these messages, and send responses to a reply queue on QM1.

The example illustrates the use of both TCP/IP and LU 6.2 connections. The example assumes that channels are to be triggered to start when the first message arrives on the transmission queue they are servicing.

Note: A message channel using TCP/IP can be pointed at an IBM Aspera fasp.io Gateway, which provides a fast TCP/IP tunnel that can significantly increase network throughput. See Defining an Aspera gateway connection on Linux or Windows.

• What the example for z/OS shows
  This example involves a payroll query application connected to queue manager QM1 that sends payroll query messages to a payroll processing application running on queue manager QM2. The payroll query application needs the replies to its queries sent back to QM1.
• Running the example for z/OS
  When you have created the required objects, we must start the channel initiators and listeners for both queue managers.
• Expanding the example for z/OS
  The example can be expanded in a number of ways.
