Hi,
I am thinking of a possibility of using MQSeries for transferring documents between different platforms. Specifically we need to transfer PDF documents between different platforms. For that matter if PDF can be transmitted, then document transfer can be an added feature to MQ.
FTP has been the choice so far. But using MQ also is a possibility as long as we can unbundle the documents at the receiving end. The advantages that I could think of right away were asynchronous transmission, with added security, delivery to intended applications and possibility of acknowledgement from the receiving end. If MQ integrator can be incorporated, you can even route the same document to multiple destinations in just one transmission from the sender side.
As of now I am not sure as to how much of coding effort is required to unbundle the documents. In fact, this might be a dumb idea in the first place, but still being an MQ guy, I am thinking its a possibility.
Please put your thoughts(pros and cons) as this I think will be a good discussion, since we are talking about replacing FTP for file transmission atleast within the MQ setup. If such a discussion has already taken place in this forum, please provide pointers to those links.
Thanks |

You're not the first to consider such advantages. Indeed there are commercial products that do just that.
CommerceQuest's Data Integrator (also re-sold by IBM/Tivoli)
and
Primeur's Spazio XSP (a very simple version is also available free) |

| Thanks for the reply zpat. That confirms that document transfer is in fact being implemented over MQ. |

When transferring documents you can use reference messages. As far as documentation goes, the idea of reference messages seems interesting to me, though I haven't actually used it.

| What do you mean by reference messages? |

Reference messages let you transfer large files from one QM to another without actually putting messages on queues. Thus, this method is resource-savvy. In order to use reference messages, you have to provide a specialized channel exit (sample is available with MQSeries installation, as far as I'm concerned).
Data that you transfer goes through the channels and is written directly to disk (as a file, not as an MQSeries message).

Hey Peter,
That was a really good example. In that discussion, the code didn't seem to bother about segmenting the contents. What was the average size of your PDF documents? Did you get into size related issues at all?
Thanks |

We have sent several megabyte PDFs ( in test) using the above method with no issues.
We have been in productio for 6 months sending 51K PDFs all day long.
MQ should not have any issues with PDF messages up to 100MEG.
