Re: Red Hat Linux 9

[Jason Antonitis]

David,   I had a similar question running 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_KERNEL forces 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.       Jason Antonitis Sr. MQ Administrator, SSG/Data Services Information Systems and Services Division Transunion, LLC.

Is this really the right value - or should I be using LD_ASSUME_KERNEL=2.4.1? The reason I ask this is that MQ 5.3 is running fine on my RHL 8 system with kernel level 2.4.20 with no specific LD_ASSUME_KERNEL settings and should therefore be using the "floating stacks" version of LinuxThreads by default (rather than the original LinuxThreads version which a 2.2.5 value would force). Has this changed with recent CSDs (i.e. does MQ 5.3 plus CSD?? now have the fixes to work correctly with both LinuxThreads and NPTL?)? Do user applications using the QM need this setting or is it just the queue manager processes? What about the IBM JDK/JRE? Does that need this as well? Thanks, David
