Re: Red Hat Linux 9
David, I had a similar questionrunning Redhat Enterprise Server 3 running WMQ v5.3. The PMR response I received from IBM was to run with LD_ASSUME_KERNEL=2.4.19 LD_ASSUME_KERNELforces every process running on the server to use Linux threads. Somewhere I found the env var AMQ_THREADMODEL_RESET=1. From what I read, this forces WMQ to use Linux Threads, but does not effect other processes. They will still be able to use NPTL. Unfortunately, I don't remember where I read this and google isn't helping this time.

Partridge" [EMAIL PROTECTED] 06/29/2004 6:10:39 AM I know there was a discussion about this while back, and IIRC the consensuswas that you should set LD_ASSUME_KERNEL=2.2.5 to run MQ 5.3 on RHL 9.0.Is this really the right value - or should I be usingLD_ASSUME_KERNEL=2.4.1?The reason I ask this is that MQ 5.3 is running fine on my RHL 8 system withkernel level 2.4.20 with no specific LD_ASSUME_KERNEL settings and shouldtherefore be using the "floating stacks" version of LinuxThreads by default(rather than the original LinuxThreads version which a 2.2.5 value wouldforce).Has this changed with recent CSDs (i.e. does MQ 5.3 plus CSD?? now have thefixes to work correctly with both LinuxThreads and NPTL?)?Do user applications using the QM need this setting or is it just the queuemanager processes?What about the IBM JDK/JRE? Does that need this as well?Thanks,David
Re: Red Hat Linux 9
Did you have to do anything in particular to get it working. I needed to set the environment variable LD_ASSUME_KERNEL=2.2.5 to be able to run some of the commands (e.g. setmqcap and crtmqm). Even then crtmqm hangs, and I can't start the queue manager (strmqm).

Re: Red Hat Linux 9
Jean-Francois, Thanks for that. IBM have confirmed that its because RH9 uses NPTL (Native Posix Thread Library). I did as you suggested and mqlicense.sh works OK now. IBM suggested as did Federico that all you need to do is create an empty file called /tmp/mq_license/license/status.dat. Thats all mqlicense.sh does. Makes you wonder what the point is, if you don't actually have to tick the box to say you accept the TsCs!

If you're getting a segmentation fault running mqlicense.sh, methinks 'tis time to open an incident with your friendly local IBM support centre.
