Running the example

For Configuration 1:

1. Start queue managers QMG1, QMG2 and QMG3.
2. Start channel initiators for QMG2 and QMG3.
3. Start the listeners on QMG1, QMG2 and QMG3 to listen on ports 1414, 1415 and 1416, respectively.
4. Start sender channel(s) on QMG1, QMG2 and QMG3.
5. Start the payroll query requesting application connected to QMG1.
6. Start the payroll server application connected to QMG3.
7. Submit a payroll query request to QMG3 and wait for the payroll reply.

For Configuration 2:

1. Start queue managers QMG1, QMG2, and QMG3.
2. Start the channel initiator for QMG2.
3. Start the listeners on QMG1, QMG2 to listen on ports 1414 and 1415, respectively.
4. Start the sender channel on QMG1 and QMG2.
5. Start the payroll query requesting application connected to QMG1.
6. Start the payroll server application connected to QMG3.
7. Submit a payroll query request to QMG3 and wait for the payroll reply.

For Configuration 3:

1. Start queue managers QMG1, QMG2 and QMG3.
2. Start the channel initiator for QMG2.
3. Start the listeners on QMG1, QMG2 to listen on ports 1414 and 1415, respectively.
4. Start sender channels on QMG1 and QMG2.
5. Start the payroll query requesting application connected to QMG1.
6. Start the payroll server application connected to QMG3.
7. Submit a payroll query request to QMG3 and wait for the payroll reply.

Expanding the example

The example can be:

• Expanded to make use of channel triggering as well as application (PAYROLL and PAYROLL.REPLY queue) triggering.
• Configured for communication using LU6.2.
• Expanded to configure more queue managers to the queue sharing group. Then the server application can be cloned to run on other queue manager instances to provide multiple servers for the PAYROLL query queue.
• Expanded to increase the number of instances of the payroll query requesting application to demonstrate the processing of requests from multiple clients.
• Expanded to make use of security (IGQAUT and IGQUSER).
