Hello all,
I am a total newbie to MQ Series. I would like to know if it is possible to put an entire DB-file in a message and put it on a queue.
If so, can anyone point me towards some coding examples? Its hard to find any sample code, and the IBM redbooks are not really good sources for samples.

You would really, really help me a lot with it.
Thanks in advance
Erwin

Erwin,
As far as sample code goes we have quite a bit on this site, just click the "Code Repository" link in the top right hand corner of your screen. As far as putting an entire DB file to a message, MQSeries makes no limitations about the content of messages. It doesn't care what type of file/information the content is. Assuming you can get this DB file into a datastructure that the MQ API will accept (usually a string or byte array) then MQSeries will have no problem moving it around in a message. However, there are limitations to the sizes of messages in MQSeries. It depends on the platform and version of MQ you are running but it is usually around 100Mb per message. If your DB file exceeds this though, you can still move it with MQSeries provided you use logical grouping of messages.

Two more thoughts in addition to Brandon's:
1) You might want to consider using reference messages (see AP Guide) if you need a file on the other end of the pipe, too
2) Be aware of codepage/encoding issues if you cross platform boundaries

Thanks, gentlemen, for the info.
That will keep me busy for the time being.

Sincerely
