RE: MQPUT and MQGET API

Hi Michael,

My program is very simple : MQGET a non-synchronous message from a queue, post 
some data on this message and MQPUT this message to the next recipient.
I have found IBM samples and with Carsten's utility, I hope I'll be able to 
write my first RPG program.

Thank you all.
Best Regards.

Jean Claude,

Generating and/or receiving MQ messages is the simple part.  If you are
attempting to integrate your AS/400 with your other Distributed MQ platforms
may be more complex then simply putting and/or getting messages.

For example, are the messages expecting replies? Do they use synchronous
or asynchrounous "dialogue"?  If replies are expected, how are they reconciled
with requests (msgId or CorrelId)?  What should happen to the messages
in queue when the Queue Manager is stopped (i.e during IPL or maintenance)?

My apologies if I appear to be "over engineering" but when (if) integrating
MQ messages in a disparate environment such as yours, it is typically
necessary (i.e. recommended) that participating applications, be they RPG,
C, COBOL or JAVA, understand the respective life cycle and model of underlying
messages.

That said, as michaelr_41 suggests, the IBM-supplied examples provide an
excellent starting point for learning/understanding the functionality
of MQSeries.  While I have never seen Carsten's utility, I'm confident,
given his contributions to the AS/400 community, it also provides an
excellent starting point for your MQ indoctrination.

Respectfully,

Michael Rooney

Hello,

We have several systems like OS/390, AIX, Windows and OS/400 in our company. 
Most of them communicate through MQ Series. We have also a software which tests 
if these communications are OK by sending a message which is forwarded over our 
network from a machine to another. Each machine reads this message and sends it 
to the next. In case of a problem, sending stops and we know were the problem 
resides. We would like to include OS/400 in this testing but we have no real 
RPG competence to create programs in our company. So we would like to know if 
someone has developed around MQ Series to create perhaps a MQPUT and a MQGET 
command on OS/400, in any case a simple way to read and put messages on MQ 
Series queues.

Thank You.
Best Regards.
