Not an answer but more an observation. Rather than the 190 queues you may want to consider grouping - say 19 queues, each serviced by 10 clients.

Hi all, Part of our MQ environment is OS/390 (2.1) and NT (5.2). We will have about 190 NT clients connected to OS/390. These NT client apps will send a request and get their replies from OS/390, based on a correlid. More than 90% of these requests will be queries. We are estimating that, for all the 190 clients combined, there will be about 50 requests and roughly 50-10000 replies per sec. The turn-around time is expected by the user to be 2-12 sec based on the importance of the request. I am thinking that we can have either: 1- One reply queue that would be serviced by all the clients, OR 2- A dedicated reply queue for each client. In the scenario 1: I know that a qualified GET would be slower from a queue with a high Q-depth (I know indexing could be used ). As far as I can see, the major downside to this approach would be if something goes wrong with this queue all the clients would suffer. In the scenario 2: If we have a dedicated reply queue for each client, MQ admin would not be very happy but the retrieval of the msgs would be faster (even if we used qualified Gets). And a problem with one queue would not effect the rest of the reply queues What do you think? Your insights would be much appreciated.
