I endorse Redback as the product of choice. Leroy Dreyfuss <[EMAIL PROTECTED]> wrote:Craig,
Since MQ is designed to be send and forget technology, and because you can have multiple listeners, there is nothing to stop you, and is, in fact, the purpose of the technology. However, remember that if you are using MQ as a means of users communicating with the database in the scenario you describe, you are using MQ as a de facto connection pool and violating your U2 license agreement if you don't have the equivalent number of U2 licenses that match the interactive users. With RedBack we do not require that, but that is because RedBack is specifically designed to provide connection pooling. And let's not forget that RB Webshares cost a bit more than database users.

But multiple mq processes can listen to the same queue, so you can run 10 phantoms listening to MY.MQ.REQUEST.QUEUE and have 100 web sessions putting messages to this queue (while listening to MY.MQ.RESPONSE.QUEUE where the mq server processes place their responses). You then use the msgid field to identify a request/response pair and all of a sudden you have a way of running many more http application sessions than concurrent phantoms. This design pattern has been in the MQ series examples for at least 6 years. Last time I checked, an MQ capacity unit (to run the MQ series server, bought from the websphere part of IBM not the U2 part) was about twice the price of a redback webshare, but I think you could make it do a lot more work.
