Configuration 1

Configuration 1 describes how distributed queuing is currently used to transfer messages between queue managers QMG1 and QMG3.

Figure 95. Configuration 1: z/OS using intra-group queuing



Configuration 1 shows a distributed queing system used to transfer messages received by QMG1 from the payroll query, to QMG2 and finally on to QMG3, to be sent to the payroll server. Refer to the list of points following the figure for more information.

The flow of operations is as follows:

  1. A query is entered using the payroll request application connected to queue manager QMG1.
  2. The payroll request application puts the query on to remote queue PAYROLL.QUERY. As queue PAYROLL.QUERY resolves to transmission queue QMG2, the query is put on to transmission queue QMG2.
  3. Sender channel (S) on queue manager QMG1 delivers the query to the partner receiver channel (R) on queue manager QMG2.
  4. Receiver channel (R) on queue manager QMG2 puts the query on to queue PAYROLL on queue manager QMG3. As queue PAYROLL on QMG3 resolves to transmission queue QMG3, the query is put on to transmission queue QMG3.
  5. Sender channel (S) on queue manager QMG2 delivers the query to the partner receiver channel (R) on queue manager QMG3.
  6. Receiver channel (R) on queue manager QMG3 puts the query on to local queue PAYROLL.
  7. The payroll server application connected to queue manager QMG3 retrieves the query from local queue PAYROLL, processes it, and generates a suitable reply.
