Hi,
I have an application running on hundreds of PCs, it access a server qmgr via mqclient. To avoid having to install mqclient on individual PCs, I figure I can install once on one machine to a shared drive, and let the rest PCs use the same installation.
For such arrangement to work, I figure I just need to get some kind of registry information and import it to every PC that need such access, without having to do a real installation.
Is my understanding correct? Has anyone done this?
thanks a lot for any insight.

That would not be a supported configuration.
You could not call IBM for help with that...

You'd need the client libraries as well, as a minimum. In this situation a silent install is the way to go.

Many thanks for the responses and insights - I was away for a few days.
I just allocated an empty lab machine to try, and see if I can avoid individual installation. Will post my result when I'm done.

Don't do it. Don't even bother testing it.
The reason is simple: if you deploy this bastard creation to your 'production' environment and then it fails, IBM will NOT help you. For that matter, nobody will help other than some consulting firm who will help you migrate the bastard creation to a properly supported setup (for a nice fat fee).
And if your boss or his/her boss see these posting warning you about the potential problems and costs associated with it, and then you still went ahead, hummm, I wonder how happy they will be?

| Does it mean pcelari should install MQ Client on individual PCs. |

YES! Roger and Wayne have offered expert advice. This same answer was given several years ago by IBM support and has not changed since then.

Here's the result of my experiment. it turned out to be very straightforward.
1. I installed MQClient into a clean machine, say, c:\ibm\mqclient.
2. regedit and export HKEY_LOCAL_MACHINE\SOFTWARE\IBM\MQSeries.
4. edit the exported registry file so it point to the intended network shared
say, m:\software\ibm\mqclient.
3. save the whole directory c:\ibm\mqclient.
4. copy it to a shared network drive, say m:\software\ibm\mqclient.
5. let windows desktop service group push the registry, AMQCLCHL.TAB
as well as the entries in MQCHLLIB, and path to individual PCs.
It works well, except some performance impact when client programs load the libraries over the network.
Eventually, I decide to build a package with mqclient installed on c:\Program Files\ibm\mqclient, and let them pushed to individual PC's instead for better performance. But I was spared from having to install in each machine. However, it is also true I can build a package by a normal installion directly on a clean PC, and let that be pushed to PCs. What's the gain? not much, I must admit, except the network share installation.

And that one way is supported and the other isn't.

I don't see the advantage of building this normal installation, putting it on a shared drive and pushing it to the target machines over putting the install media on a shared drive and doing a silent installation on the target machines.
