MULTI-HOPPING : ( gate way)

Passing the messages between more than one intermediate queue managers is called Multi-
Hopping and Intermediate queue manager name called Hopping.


PROCEDURE TO CREATE MULTI-HOPPING:

1. Create a queue manager QM1, QM2, QM3, Start the queue managers QM1.

2. Create a remote queue with attributes local queue name (Remote Queue     Manager) i.e Rname (QM3_LOCALQ) & RQMname(QM3) and the transmission queue called XMITQ (TQ).

3. Create a transmission queue called (TQ).

4. Create a sender channel from (QM1.QM2)

5. In Qm2 create, Create a receiver channel (QM1.QM2)

 

6. Create a transmission queue with name target queue manager name called QM3.

7. Create a sender channel from (QM2.QM3) with transmission queue called XMITQ (QM3)

8. In QM3 create a local queue called (QM3_LOCALQ) which is defined in remote queue of QM1 Rqueue(QM1)

9. Create a receiver channel (QM2.QM3)





10. We should have two listeners started and running in QM2 and QM3.

Testing:

Put message to the RQD (RemoteQ ) on QM1 queue manager

 Check the queue depth QM3_LOCALQ on QM3 queue maanger.

 

Message is reached to the destination queue, its proves that using multihopping setup we can communicate multiple queue intermediate queue managers. 

Note:

For every queue, except remote queue we have two properties.

1. open input count ( Iproess )

2. open output count ( Oprocss )

3. the application which is connected and putting the messages is called “ O process “

4. The application which is processing(getting) the messages is called “I process “
