Is it possible to set the ports that MQ responds to a request on? The Q-Manager is listening on 1414 but responds on a random port. I would like to force it to use a specific port or ports when responding.

You can change the port a sender channel sends on by using an environment variable to limit the port number. The receiver will then send back to that port number but it uses port 1414 to initiate a return conversation. You use the environment variable MQTCPSDRPORT = llll,hhhh where llll = the lowest port & hhhh = the highest port to limit the ports the sending channel uses to initiate a conversation.
This applies to ver 5.0 up.
see the excellent article MA86 in the mqseries support pack site for more info |

Is anyone familiar with setting the MQTCPSDRPORT variable?
What I mean is, how should you determine the range of ports to allow access out from your server?
I need some criteria on which to base a recommendation for how many ports to make available for use (there is no shortage, but I want to minimise the number used), so any experienced views would be appreciated... |

When using sender/receiver pairs each sender channel will use a single port, at leat thats my experience from viewing on netstat! Your channels are most probably going to remain active for quite a while so I'd open up at least one port for each channel. If you expect growth then I'd allocate more to save administrative hassel with your firewall people.... Do you think it might be more complex than this?
