Can someone tell me or point me to where I can learn more about what exactly happens when MQSeries channles connect over a internet? I know a connection is made but it cant be a physcial one. I need more info. Thanks,

This is a really confusing question.
What, exactly, is a "physical" connection and what makes you think that MQ traffic isn't "physical"?
As far as I know, the actual protocol that occurs between two MCAs is undocumented and proprietary.
As far as I know - and I can't see how it would be any other way - MQ traffic over TCP/IP is just another TCP/IP connection. That is, it's the same as any other TCP/IP traffic - except for the application level logic that, again, is propriatary and undocumented.
What are you really trying to do or what problem are you trying to solve? Can the MQ Internet Transport Passthru (IPT) support pack help? Can SSL help?

Hello,
I am not trying to solve a problem. I was wanting to understand more about what happens when channels negotiate. It is confusing to me which is why I asked. But you put it into perceptive for me.
Thanks for your quick reply..

I think this is a good question. Of course it will be a ONLY a TCP/IP connection as many other, too - but there is definitely a difference HOW MQ uses the various alternatives to connect two peers together especially in the context with various MQChannel Types.
Actual we have e.g. a big problem to connect clients with MQ C/S-Connection Channels via a CSS Layer-7 Switch, because the MQ TCP/IP socket handling and the keepAlive-algorithm of the Layer-7 Switch are not directly compatible - and to solve such a problem it's already necessary to know exactly HOW the MQ Channel mechanism physically acts. In particular, when the same connection via MQ Q/Q-Channels (Sender -> Receiver) works without problems. |
