publish and subcribe

Hi

I published one document the corresponding trigger is in disabled state so where this publishable document will go. The trigger was disabled state so I not seen any documents came in client queue. After sometime I enabled the trigger but the document was not received. Is this publishable document will lost? I checked the corresponding publishable documenttype in broker it is showing it hit the document. The count has been increased.

Can you please advice someone.

Thanx Balu

Balu,

If your trigger is disable the published document gets lost or doesn’t stay in the queue unless you have IS clustering.

Thanks Khan
My server are in cluster only. So where can we find the document. The triggers are disabled in all servers.

Thanx Balu

Should be in the queue

When all triggers are disabled, it means no subscriber for the publishable document. What I observed is… in this case the broker do not save the published document.
Ofcourse I may be wrong in a way that I should change some settings on the broker.

If your triggers are disabled then the document is discarded. You can suspend your triggers if you need to pause for some reason and the document will be placed in the associated client queue for that trigger but disabled means discarded because as said earlier there are no subscribers.

Yes it has been discarded i suppose. But what is the use of guaranteed delivery. If we are mentioning the publishable document is guaranteed delivery wt is meant by that. And what is the use of Document Store.

Please advice.

I’d read through the Pub/Sub Guide to get a more detailed understanding of how the IS Dispatcher works in conjunction with the Broker. It will guide you through the different situations. It will also give you more detail on how Guaranteed Delivery works.

A disabled trigger will not store the docs for you. Why would the trigger be disabled if you want it to process messages? If you need to temporarly suspend processing the IS gives you that option while maintaining your documents.

Guaranteed delivery means that once a published document is given to the Broker, it will guarantee that it is delivered to all subscribers. If there are no subscribers (in your case, the trigger was disabled and so there was no subscription), then there are no deliveries to make–thus the document is thrown away.

The Broker added a “dead letter queue” facility in recent versions. This queue is the recipient of documents that have no subscribers.

Hi Rob
Can you please explain me more about “dead letter queue” facility in recent versions. In which versions of webmethods it is coming. Why trigger is disabled means some times we are facing in our environment when we restarted the servers automatically some of triggers are disabled (showing not connected) if we restars again its connecting. As from all replies I am concluding guaranteed delivery will come in to picture when the documents reaches to the client queue. Is it correct?

6.1 introduced the ability to create a dead letter queue. Refer to the Broker Client Java API Programmer’s Guide for info.

As for why the triggers are becoming disabled, someone would need to troubleshoot to investigate what exactly is happening. It may be appropriate to open a support request with wM.

Documents will be queued up in the Broker client queue.

To which post are you replying Kagzi? It seems that you may have missed some of the points in the discussion?
