Hi friends,
I am using WMB 7 and WMQ7. I have a message flow with a MQ i/p--compute--publication node. My question is a what happens when a message comes out of a publication node. Is that it will store the message temporarily in system.(broker or default) queue or where it will be before subscribing?
Waiting for your response |

Depends entirely on what kind of publication, what kind of subscription and how you're got things set up.
Check the documentation for additional details on the various possibilities.

Hi Vitor,
For instance I am publishing a JMS message through publication node. I need both JMS application subscriber and Message Broker to get the published message.
My question is how a message flow which starts with JMS input node can get the published message.
Is that I have to put the subscribed JMS message in a queue and get it in the message flow using JMS node or any other options is there?
Thanks |

It subscribes.

If you re-read the relevant documentation, you'll realise that question very much answers itself.

Read the documentation as I suggested.
Or just think about what you're asking. And what pub/sub means. Then be ashamed.
