Hi folks, the way MQ is used at our shop is to send data to an MQ queue and then a web application gets the data from it (although, I don't how that's done). So, my understanding is that MQ does not send/push data to another system. My question is, is it possible for MQ to send/push data to another system? If so, how could that be done?
Thanks, Frank |

That's the only way MQ does it - by sending data to a queue. If you mean "can MQ put data directly into another system, via an API or similar, bypassing the intermediate queue" then the answer's no.
Base MQ can notify the target system that there's new data and there's 1-n ways of getting the data off the queue (which goes up to 1-x ways if you use message broker, adapters or another Websphere product where x is an integer significantly larger than n) 
This is a deliberate feature (as opposed to the other kind of feature  ) as it allows sending & recieving applications to be decoupled; i.e. there's no requirement for them both to be available when the data moves. If you're looking for fully syncronous conversations then you might as well be using TCP/IP Sockets!
Hope that helps.
P.S. if that wasn't what you meant, accept my apologies and correct me!

| I just wanted to be sure that I understand that MQ just puts the data in a queue and you've explained that in a way that even I can understand. Thanks again! |

From other posts I see that PM4Data is the tool that works best with MQ to send contents of queue's to other systems. Is that what everyone else uses?
Thanks |

In fact, this is entirely not what PM4Data does.
PM4Data allows you to move files from one place to another. It happens to do this using MQ, and it happens to be good at moving files from one place to another.
The contents of queues are messages. The tool that works best to send messages from one queue to another is MQ.
If you have messages on a queue, and you need to send those messages to another computer or another company, the best tool to use is also MQ.
If the other computer doesn't have MQ installed on it, then you can install an MQ client.
If the other company doesn't run MQ - then you need to put the messages into some other kind of container (perhaps a file), and send that container to the other company. You could use PM4Data to put the messages into a file - with some configuration work - and PM4Data is a reasonable tool to do this.

That is definitely a good product to look at.
Other thing is if you have two machines MC1 and MC2 and if they both have MQ, then MQ can send data from MC1 to MC2. |

| I'm a shop that doesn't think much about the AS400 (or whatever it's called these days) so the system that MQ works with now are non-AS400 servers, WINNT machines. So, is MQ client used frequently and is it stable, etc.? What about other transmission software like Townsend, Trailblazer, etc. could they b/used like PM4Data? |

What do you want to move from one place to another?
Data inside applications? Or files?
What platforms do you want to move this stuff between?
What type of applications need to send or receive this stuff? Can you change those applications?
Your first post in this thread said you wanted to take data from an application and have a web application receive that data. So you had an application that PUT messages onto a queue, and the web application then GOT the messages off the queue. Without buying anything else (other than maybe more MQ licenses), you can change what computer this queue lives on. In fact, you can make more copies of this queue than just one, and have data on all of them all on different systems.
This is done by creating an MQ network between more than one queue manager, and configuring MQ channels so that data will move where it needs to go.
You should really read the MQ Primer - it's a support pack and if you search this webpage for "MQ Primer", I'm sure you'll find a direct link.
It will help you understand what MQ can and can't do and how MQ is used. Then you can start to map that back to what you want to do - which we're all not quite clear on I think.

Vitor responded an answer...no to the question so I thought I stated the question well enough.
What I'd like to have happen is that when data arrives in an MQ queue that it then moves (gets put) from that queue to another server. The other server is not an AS400 (MS server) and is not running MQ (and there’s no plans to load MQ client). Further posts say the only way to do this is with a 3rd party product since the AS400 does not provide the way to move the data. We've been running MQ for years and the applications won't be rewritten to go directly from a file to the other server, which is why I asked the question.
The network folks think MQ s/b able to move the data to the server but can't and I’d like to figure out a way to push the data from MQ.
Additional thoughts? |
