| I am new to MQ so I don't have a good feeling on how many queues there should be. I am building a cluster with a gateway that will round-robin all messages on queues defined on all q managers. Is 500 queues way too many? I have ~500 stores connecting and I wanted each to have their own queue. Thanks. |

i feel 500 is not a big number at all.... for MQ..
however might prove painfull to administrator managing it...
but one queue per application is justified enough...

| You think one channel is enough for 500 applications? |

channel is not concerned with applications...
whn u say one queue per application... i take it as each application is putting or getting msgs from its own queue....
between two queue managers you should have only one pair of channels for one way communication unless, you want to seperate the flow of some msgs, due to some rsn......

We have a batch that dumps a lot of messages into 2 remote queues on qmgrA. We set up a chl for each remote queue between qmgrA and qmgrB to get better throughput. (WSMQ V 6.0.2.2)

i remember reading sometime back that having parallel channels is ineffective if we are setting them for improving channel performance....
so i learn here  thnx

Well .... it really depends on your environment.
If you are maxing out at channel throughput another channel will help. If you have problems with the log file or the bandwidth or the box io capacity another channel will be of little help.
I should have mentioned perhaps that the sender is a mainframe and the receiver is AIX MQ V6.0.2.2...
Enjoy
