I have a C++ module on Sun Solaris that works fine with MQServer. Can we expect that the same code will work THE SAME without any concern about the new Client configuration? This doubt because we noticed that MQClient libraries have different names from MQServer ones...
Thanks in advance for any hint about it,
Cheers

The decision as to server or client bindings is a link time decision, not a compile time one (ie you link with mqm or mqic*).
The same code 'should' work, but you can should also bear in mind coding to deal with expected errors - Thats not to say you couldnt get the same errors on a server based app, more that the window for problems is larger and with more variables (especially the network) |

Thank you Jason.
I agree about the fact that we probably will have to consider more robust error handlings (e.g. if the network is down, we have to retry the connection to the QMgr while in the server edition, if the connection to the QMgr fails, the problem is probably serious and we stop our adapter) but at the moment we would like just to verify the link phase so your considerations are just helpful!
Cheers,
Andrea |

If your code includes the MQBEGIN verb, it will not work in client mode, even though it works in bindings mode.
Otherwise, it will work either way with no changes (by design).
