I was looking for information on the likelihood of using MQSeries software as an actual mechanism for transfering entire files, not just messages. Can MQSeries be used in place of FTP? Is this possible? If so, is it effective? Anybody?
Thanks,
Dennis |

Well it can replace FTP, I have used for file transfers at another job.
It will take longer to send the file with MQSeries than FTP, but with FTP
you are not sure all the file got there without more coding to check.
MQSeries will help if you are using server-to-server the app that sends the file wont fail if the network connection is down, and when it comes up
MQSeries will transfer it So if your network infrastructure has problems this will help keep apps from failing becuase of it.
With MQSeries v5.1 and V5.2 you have limit of 2.0GB of data on a queue
so if lots of programs use the same queue to send files it is possible to
fill up the queue, GOOD News v5.3 pushs the limit to 2 TB.

Dennis,
MQSeries provides a functionality called reference messages. It's a very convenient way to transfer large amounts of data (files) without having to break them down into individual messages. For instance, if I want to transfer a huge file that's on my local drive, I create a reference message, and in it, I provide the full path to the file I want to transfer. When I put the message, MQSeries will automatically transfer the file from my local drive to the drive on the receiving queue manager. So it basically let's you replicate ftp in the MQSeries environment.

Well they provide that, but if you read into it you have to provide the exit code to retrieve the file and send it.
From IBM Manual
This method allows a large object to be transferred from one node to another without the need for the object to be stored on WebSphere MQ queues at either the source or the destination nodes. This is of particular benefit where the data already exists in another form, for example, for mail applications.
To do this, you need to specify a message exit at both ends of a channel. For information on how to do this, see WebSphere MQ Intercommunication.
WebSphere MQ defines the format of a reference message header (MQRMH). See WebSphere MQ Application Programming Reference for a description of this. This is recognized by means of a defined format name and may or may not be followed by actual data.
To initiate transfer of a large object, an application can put a message consisting of a reference message header with no data following it. As this message leaves the node, the message exit retrieves the object in an appropriate way and appends it to the reference message. It then returns the message (now larger than before) to the sending Message Channel Agent for transmission to the receiving MCA.

There is a product of file transfer over MQ from Primeur (http://www.primeur.com) but I have never tested it.
