Hi,
I have an installation where I have two different configurations: one machine has a local mq server installation and i run on that machine with local queues (using MQCONN), and another machine has my client application which connects to that same server remotely (using MQCONNX). These are both running on solaris.
Currently i build two versions of my app, one with lib mqm (for remote queues) and one with mqic (local queues).
Is it possible to configure MQ and build an app in such a way that you can use the same binary application to connect to both local server/local queues and to a remote server/remote queues? e.g. Can you configure channels on a server installation such that you can use MQCONNX to connect to it, even from the same machine?
I've seen other related postings, but they all seem to indicate that you need to link to different libs. Is this an MQ peculiarity that you have to build two versions of an app depending on where the server resides?
Many thanks,
erg. |

Yes it is entirely possible to do this by dynamically loading the library at runtime. We do this with a wrapper library which goes looking for MQ server libraries first and then loads MQ client if server is not found. It has to be platform specific.
Have a look in the C++ repository here on mqseries.net at the ntloadmq, sunloadmq and slloadmq samples for Windows, Sun and AIX examples.

The perl modules do this as well, although they strongly prefer the server bindings connection when available.
