Distribution Setup in Websphere MQ or Point to Point Setup

Create a point to point or Distribution MQ Setup:  

   A communication between two queue managers to send or receive the data is called distribution queuing or point to point setup. 

       QM1                                                     QM2

1. QUEUE MANAGER                          1.QUEUE MANAGER

2. LOCAL QUEUE                                 2. LOCAL QUEUE                   

3.QUEUE REMOTE                               3. REMOTE QUEUE        

4.TRANSMISSION QUEUE                  4.TRANSMISSION QUEUE                

5. SENDER CHANNEL                         5. SENDER CHANNEL

6.LISTENER                                           6. LISTENER

7.RECEIVER CHANNEL                       7.RECEIVER CHANNEL      

THEN START THE CHANNEL                    

OPEN THE COMMAND PROMPT 'RUN AS ADMINISTRATOR'.

1.Create Queuemanager as 'QM1'

                  CRTMQM QM1

Start the Queue manager

                 STRMQM QM1

 Enter into the Queue manager

                RUNMQSC QM1

 

 2.Create Local queue

             DEFINE QLOCAL(LQ1)

3. Create Remote Queue

                DEFINE QREMOTE(RQ1)  RNAME(LQ2)  RQMNAME(QM2)  XMITQ(QM1.XMITQ)

4 Create Transmission Queue.

                DEFINE QLOCAL(QM1.XMITQ) USAGE(XMITQ)

 

5.Create sender channel

     DEFINE CHANNEL(QM1.QM2) CHLTYPE(SDR) CONNAME('LOCALHOST(2012)')   XMITQ(QM1.XMITQ)

6.Create receiver channel 
          DEFINE CHANNEL(QM2.QM1) CHLTYPE(RCVR) 

7.Create Listener

         DEFINE LISTENER (L1) TRPTYPE(tcp) PORT (2011)

 

EXIT FROM QM1: > END

QM2 CREATION:

1.Create Queuemanager as 'QM2'

                 CRTMQM QM2
Start the Queue manager

                 STRMQM QM2

Enter into the Queue manager

                RUNMQSC QM2

 2.Create Local queue

             DEFINE QLOCAL(LQ2)

3. Create Remote Queue

                DEFINE QREMOTE(RQ2)  RNAME(LQ1)  RQMNAME(QM1)  XMITQ(QM2.XMITQ)

4 Create Transmission Queue.

                DEFINE QLOCAL(QM2.XMITQ) USAGE(XMITQ)

5.Create sender channel

   DEFINE CHANNEL(QM2.QM1) CHLTYPE(SDR) CONNAME('LOCALHOST(2011)') XMITQ(QM2.XMITQ)

6.Create receiver channel 
         DEFINE CHANNEL(QM1.QM2) CHLTYPE(RCVR) 

7.Create Listener

         DEFINE LISTENER (L2) TRPTYPE(tcp) PORT (2012)

•          START THE LISTENER

                   START LISTENER(L2)

•          START THE CHANNELS 

                   START CHANNEL(QM1.QM2)

                   START CHANNEL(QM2.QM1)

•          EXIT FROM QM2

                         END

 Enter into QM1 and Start the Listener and channels

Start Channels: START CHANNEL(QM1.QM2)

                             START CHANNEL(QM2.QM1)

start listener: START LISTENER(L1) 

Here i will give some commands.

channel status: DISPLAY CHS(CHANNEL NAME)

                             DISPLAY CHS(QM1.QM2)

To change or alter any attribute for mq objects:

DEFINE CHANNEL(QM1.QM2) CHLTYPE(SDR) CONNAME('HOST(2012)') XMITQ(QM1.XMITQ)

HERE I WANT  TO CHANGE CONNAME 'HOST'  TO 'LOCAL HOST'

ALTER CHANNEL(QM1.QM2) CHLTYPE(SDR) CONNAME('LOCALHOST(2012)') XMITQ(QM1.XMITQ)

Now the setup is completed. We will test the setup by sending messages.

• TO PUT A MESSAGE WE CAN USE BELLOW  COMMAND: 

AMQSPUT <DESTINATION LOCALQUEUE> <DESTINATION QUEUE MANAGER>

AMQSPUT LQ2 QM2

• To get a message we can use bellow command.

AMQSGET <LOCALQUEUE NAME> <QUEUE MANAGER NAME>

AMQSGET LQ2 QM2
