Publish and Subscribe Scenario

Step1:-
Create a flow like below Publish Messageflow
MQInputNode--->ComputeNode----->Publication Node

Configuration on Nodes:-
MQInputNode:-
Queuename: PublishQueue
Input Message Parsing: XMLNSC

ComputeNode:-

   SET OutputRoot.MQMD.Format =  'MQFMT_RF_HEADER_2';
 SET OutputRoot.MQRFH2.(MQRFH2.Field)version = 2;
 SET OutputRoot.MQRFH2.(MQRFH2.Field)Format = 'MQSTR';
 SET OutputRoot.MQRFH2.(MQRFH2.Field)NameValuCCSID=1208;
 SET OutputRoot.MQRFH2.psc.Command='Publish';
 SET OutputRoot.MQRFH2.psc.Topic = InputRoot.XMLNSC.publish.topic;
 Declare PTR REFERENCE to OutputRoot.MQRFH2;
 Detach PTR;
 attach PTR TO OutputRoot.MQMD AS NEXTSIBLING ;
 SET OutputRoot.XMLNSC.data.info = InputRoot.XMLNSC.publish.info;

Publication Node:-
No configuration needed.

Test Input:-
 <publish><topic>Bhanu</topic><info>Sample</info></publish> Put this Message in  PublishQueue
to publish

Step2:-
Create a flow like below Subscribe Messageflow
MQInputNode--->ComputeNode----->MQOutput Node

Configuration on Nodes:-
MQInputNode:-
Queuename: Subscription
Input Message Parsing: XMLNSC

ComputeNode:-

   SET OutputRoot.MQMD.Format =  'MQFMT_RF_HEADER_2';
 SET OutputRoot.MQRFH2.(MQRFH2.Field)version = 2;
 SET OutputRoot.MQRFH2.(MQRFH2.Field)Format = 'MQSTR';
 SET OutputRoot.MQRFH2.(MQRFH2.Field)NameValuCCSID=1208;
 SET OutputRoot.MQRFH2.psc.Command ='RegSub';
 SET OutputRoot.MQRFH2.psc.Topic = InputRoot.XMLNSC.subscribe.topic;
 SET OutputRoot.MQRFH2.psc.QName = 'RegSub';
 SET OutputRoot.MQRFH2.psc.QMgrName ='TEST';
DECLARE PTR REFERENCE TO OutputRoot.MQRFH2;
 Detach PTR;
 attach PTR TO OutputRoot.MQMD AS NEXTSIBLING ;

MQOutput Node:-
Queuename: SYSTEM.BROKER.CONTROL.QUEUE 

Test Input:-
<subscribe><topic>Bhanu</topic></subscribe> Put this Message in  Subscription
to Subscribe.

Objects to be Created:-

Create PublishQueue,Subscription,RegSub as three queues in MQ for testing

Direction to Test:-

First put the message in Subscription and then in the  PublishQueue, then you can see the message in RegSub queue due to publish and subscribe properties configured in message flow.
