hello all,
i am a new MQ user, i am trying to get my hands dirty with MQ. i was playing with MQ v6.0 from windows paltform and i am albe to create local, remote, alias queues. but i have problem in understanding the creation of reply queues.
can some help me in understanding how i can create this queue and can give some light which scenarioes this queue will be used(if possible please give some practical scenarios).
it will be really helpfull if given step by step procedure on how i can create one from windows MQ Explorer.
the other queue i have problem is with
model/dynamic queue.
this might be basic question, but its a huge thing for me.
thanks

| Take a look at the amqsreq0.c sample. This program acts as a requester to a server and uses a model queue to dynamically build the reply queue that the server will use to send back the reply. |

If you're defining a queue to accept replies, it's just a local queue.

Model queues are created like any other, if that's how you're accepting replies.

You need to look at the suggested code sample & read the documentation (Intercommunication manual is a good place to start). Request / reply can be implemented in 2 ways: replies go to a local queue and are retrieved by correlation id, or a dynamic queue that serves a single application.
The one you use is entirely dependant on your needs and circumstances; there's no "right" way.
Though you will find many posts in here discussing the point.

hello, thanks for your replies.
i did go through the code that is mentioned.
please correct me if i my understanding is wrong.
it lloks like the reply Q is local queue, but at the same time it is remote queue for some other Qmanager whose application puts the meesage in it.
right...? |

Yes, though there may not be an actual remote queue on the other queue manager, depending on your design.
If you think about it, all local queues are remote queues to other queue managers, conceptually speaking.

Bridfly:
A QModel is a template definition that sysadmins create so that application programmers can create a queue dynamically. The programmer opens the QModel name, and specifies the rule for how the resulting local queue is to be named. If the open is successful, a local queue is created with the attributes from the QModel definition, and the name of the dynamic queue is returned to the programmer.
