| OK I have been an MQ Admin for about a month now and thanks largely to the support of this forum and a lot of reading I have not blown anything up yet. But I do have another question and please excuse me if the answer is obvious... We are currently using MQ 6.0 and the pub/sub functionality in WMB 6.1, but if/when we upgrade to MQ 7.0 can we not get rid of WMB 6.1? In short if MQ offers pub/sub functionality why would we need to purchase WMB? What is the upside? What am I not understanding? |

2 points (there are others):
- WMB has a far more robust & scaleable pub/sub facility than WMQ
- WMB does far, far more than pub/sub
A 3rd important point is that WMQv7 has much better pub/sub than v6 so one possible answer to your question is "you don't need WMB", depending on exactly what you're doing in terms of pub/sub.
Another possible answer is "you don't understand how to get the best from WMB and all it's features".
Your final answer is probably between these someplace.

so in short I need to know specific user case scenarios before I can decide if MQv7 is sufficient for my needs. What would be some specific examples of why MQv7 would not be sufficient? Sorry if I am asking too many questions but from all the documentation I have been reading I still cannot locate a point of delineation between using WMQ and MQv7.

More then likely this is my problem. Like I said it has only been about a month and my head has been swimming from the constant reading and learning a new tool. But I can now see light at the end of the tunnel... |

I'll assume you mean WMB & WMQv7.
In terms of pub/sub there's no difference AFAIK in terms of functionality. Where the difference comes is how the software supports that functionality, the scalability underpinning it and the administrative controls offered. Hence my comment about how you use it.

Even a brief skim through the WMB documentation will show you the vast range of features it offers that WMQ does not. To take a theoretical and specific example WMQ doesn't allow a non-WMQ aware application (like an old fixed file format COBOL or a Java web app) to publish via the queue manager without changes. Both of these can use WMB to publish without code changes.
If this and the other abilities of WMB are of no interest to you, and your pub/sub is fairly small scale, then maybe you don't need WMB. Or maybe you do. It really does depend entirely on what you're using the software for.

In a nutshell, WMB does message transformation and content based routing, for MQ messages along with a multitude of non MQ based transports. It can connect various message transports. All, some or none of your application's end points could be WMQ when you have WMB sitting in the middle (although the Broker's underlying guts uses MQ heavily for its internals).
When talking about pub/sub with WMQ 7 and WMB 7 my understanding is that WMQ 7 is as capable and scalable an engine as you need. WMB 7 in fact completely relies on WMQ 7's pub sub engine. The only time you need WMB 7's extra pub/sub capability is if you want to route publications to subscribers based on the content of those publications.
Check out the WMB 7 Annnouncement Letter here, it may summarize all this for you better then trying to plow thru hundreds of pages in the Info Centers.

Are you in a position to outline for us your requirements?
If not, that is understandable (eg. if you want to protect sensitive information). But if you can, then it may help this discussion a bit.
Are you using WMB purely and simply for publish/subscribe today? Do the flows do transformations, database access etc. too? Is the broker doing selection of messages based on message contents? |

I have a meeting scheduled with the business unit tomorrow and I plan on getting detailed user requirements and case scenarios. Hopefully after that I can offer specific examples to drive to a better discussion and solution. |
