I have a simple flow for publishing a topic :

MQInput -> Compute -> Publication.

The flow for subscribing is :

MQInput -> Compute -> MQOutput.

The compute node for subscribe flow has the following ESQL:

SET OutputRoot.MQMD.MsgType = 1;
SET OutputRoot.MQMD.ReplyToQ = 'SUBQ1';
SET OutputRoot.MQMD.Format=MQFMT_RF_HEADER_2;

Set OutputRoot.MQRFH2.psc.Command='Sub';
Set OutputRoot.MQRFH2.psc.Topic='IBM/Price';
Set OutputRoot.MQRFH2.psc.QName='SUBQ1';
Set OutputRoot.MQRFH2.psc.QMgrName='WBRK_QMGR';

where SUBQ1 is the queue where i want the subscriptions to arrive

What is the message that i should put in MQInput node of the subscribe flow? Is my flow correct? Or do i need any more flows?I am not using any JMS application as of now.

Thanks,
Apurv.

You don't need a "subscribe flow" to send a subscription registration to the broker. Write the flow that receives from your SUBQ1 queue and process the publication.

Use something like rfhutil (support pac IH03) to register a "static" (my term) subscription. Then when your publication flow produces a publication, it will be received by your SUBQ1 flow and processed.

Hi Apurv,

Whatever you have done is correct. You can probably get the value for Topic, QName and QMgrName from input. You can have it as an XML and parse it to get the value. Dont forget to set the Domain to XML in input node node incase you are using XML as input msg. Hope you have given the correct broker queue name in output node.

Thanks.
Pranava.
