Hi,
Just wondering ... can application built in C/C++ that are compiled and linked with the MQ Server libraries be used as an MQ client application without relinking the codes? Is there any code changes required? Can I use the application that are linked with the server libraries be used as a server app in one instance and client in another?
thanks in advance

To my knowledge and according to the literature, No.

Happily No.

That's the same question as the first, repharsed. The answer is still no.
What you do in such cases, is link with the client library, and if you wish to work on a local QM simply work as a client but locally - specify localhost in the MQSERVER. This gives you the option to use the same complied program to work either locally or remote.
There is very little performance degradation for clients when working locally. |

You might be able to get away with coding your program to have stub API calls that get resolved at runtime through the use of LoadLibrary and GetProcAddr. Take a look at the ntloadmq.c program at:
