Question 1:
How can I make a transporting queue that can be triggered to place msg?
I knew the trigger mode that can be used to trigger an process app and it can also be used to trigger a queue to transport msg. But now I can not find the doc describe this pattern. Could anybody give me a hint?
Question 2:
Two MQserver on different server apart , there're many queues on A's qmgr and there is a certain queue(local or remote) on B's qmgr,I want B's queue can receive the messages from clients connected to B and distribute these messages to all of the queues on A automatically.
Could somebody help me? |

You're looking at a distribution list. Though I'd put a bit of redesign in and go pub/sub myself.

And for xmitq triggering (channels) check out the intercommunications guide.

I just wonder if I can do this using Pub/Sub.
And I use this method.
Having created queues named by 'SYSTEM.JMS.ND.CLIENTDOMAIN.Q1, Q2 and Q3' in 'sender',key code is...
JmsTopic abcTopic = ff.createTopic("topic://foo");
abcTopic.setStringProperty(WMQConstants.WMQ_BROKER_SUBQ, "SYSTEM.JMS.ND.CLIENTDOMAIN.*");
producer = session.createProducer(abcTopic);
producer.send(tmessage);
Then I make a receiver to retrieve the message, code is...
destination =session.createQueue("SYSTEM.JMS.ND.CLIENTDOMAIN.Q1");
consumer = session.createConsumer(destination);
consumer.setMessageListener(this);
I know I should receive the message from topic("topic://foo"), but if I also can get the message from the sub queue specified?
Why do I get nothing from 'SYSTEM.JMS.ND.CLIENTDOMAIN.Q1'？ |

Pub/sub relies on the underlying transport mechanism working. So you'd still need to handle the channels.
I wonder why you're wondering if you can do this with pub/sub, when I've already suggested you try pub/sub? Perhaps you think I'm pulling your leg....?

Ah - thought you were wondering why you were getting no messages on the subscription queue. My bad.

oh... it is really a question.
Why do I get no messages from my subscription queue? If I created a consumer with a topic and it will receive the message correctly. But I can't get any messages from the subscription queue I specified directly,why?
Maybe I should read more doc.... 
Here I've asked two questions.
One is the above, and the other one is how to make two brokers connected.
Sorry, a little confused. |

You think? 
Having said that, there's nothing wrong with a little experiementation. But it should be combined with reading the documentation, and using the documentation to figure out why the experiment is failing.
There's also a strong case for formal training, though in this new world economic order that's not perhaps as easy as it once was.
Do not despair, keep trying, keep reading. And remember this forum is not designed as a training resource.

How to do pub/sub is described in the Pub/Sub manual. Stick with simple examples and work up.
Do not attempt this until you have got the 2 queue managers properly linked. This has nothing to do per se with pub/sub or your original "how to I send messages to 100 queues" question. Focus down, read the Intercommunication manual and the help you've been given here. Work through the steps, solve the problems you encounter and use the sample code to test.
Do not despair, and Happy Reading!

Here is where you are going wrong.
You can publish to one topic.
If that topic is subscribed to multiple destinations each destination would receive a copy.
The publication topic and subscription topic need not be the same.
Send your subscription messages with a JMSReplyTo destination. The answer to that destination will give the information about the subscription operation of the broker (RFHUTIL is your friend).
Finally you do not subscribe to a topic with a wildcard in the destination. The wildcard should be in the topic string. This way you can read the messages either by doing a receive on the topic, or by doing a receive on the queue.
The mq JMS packages relevant to the topic show no method like
| Code: |
| abcTopic.setStringProperty(WMQConstants.WMQ_BROKER_SUBQ, "SYSTEM.JMS.ND.CLIENTDOMAIN.*"); |
I suggest you review the way to create / set your topic. Use the URI mode to define your topic. I suggest you experiment with JMSAdmin and the file based context. This will show you how to create the URI to add the Destination into your subscription topic.
Have fun

And I 've make a cluster containing A's qmgr and B with channels.
Then, they're seen with each other at explorer.But now brokers on two qmgr can be connected? or have been connected? I don't know how to set channels(Sender and Receive Channel?) to make multi brokers connected and communicated , what's the next step?
My goal is the message placing on topic of A's qmgr can be received by subscribers on relative topic of B's qmgr. Is the problem about remote broker connected and add muti brokers to broker Topology?
Which commands I should take ? |

Read the documentation, and think about what you're asking, and why you don't need to ask.

This is the goal of all pub/sub. It'd be a bit pointless if all the subscribers had to huddle round a single publisher like cavemen round the only fire.

No, the problem is you're not a) thinking through what pub/sub is and b) not reading the documentation on how this is supported. Ask yourself if someone might have encoutnered this situation before, or if IBM might have thought most people would want to do this (my comment above refers). Ask yourself if IBM might have pre-empted your problem with a solution. Ask yourself what they might have done, and then read the pub/sub doc again.

What you should take is more time to read. And experiement. Then re-read based on the outcome of your experiment.
And get training. It's amazing how much a quality course can cover on a complex product like this.
