Re: File transfer

Title: RE: File transfer

We had a similar requirement where we needed to send huge files. We also ran into performance issues however our Tech. Team suggested a few options. I am listing them below.

1) If you are using MQ on a windows box, you could zip the files and send these and unzip and process on the other side.

 

2) Another option would be to have an intermediate Box where you could keep your drawing files and in the Message just send the file location and other required parameter's. This would keep the message size small.

 

3) Alternatively, if you are using an RDBMS like Oracle you could save the files in the BLOB format and send only the Record level information. The application could connect to your database and pick up the BLOB files.

 

Hope you find these useful. In any case do let me know how you tackled this one ....

 

Regards,

Vindya

We have small file transfers over MQ, but with big files like we quickly ran into problems with logging. Even with non-persistent messages we would get huge logs. Not to mention poor performance for other applications.

We also tried reference header messaging, but that was a pain with recovery and security.

We are now looking into alternative ways of big-file-transfer as opposed to MQ.

Hi All,

Does anyone have some sample code, suggestions or recommended techniques
that they are willing to share to do file transfer of large (120MB) drawing
files over MQ?

Thanx,
