Hi,
I'm trying to install MQSeries 5.3 (I read other thread in this forum about installing MQ 5.2 on RedHat 9 succesfully).
I had to set LD_ASSUME_KERNEL=2.2.5 for mqlicense.sh stuff.
The rpm's were installed succesfully.
But when I need to do something, specifically
crtmqm -q SOME.SILLY.QUEUE.MANAGER.NAME
the program enter in a infinite loop (I need to kill-9 the pid).
I run the command with the strace utility. The relevant part follows:
| Code: |
open("/etc/group", O_RDONLY) = 5
fcntl64(5, F_GETFD) = 0
fcntl64(5, F_SETFD, FD_CLOEXEC) = 0
fstat64(5, {st_mode=S_IFREG|0644, st_size=616, ...}) = 0
old_mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x40023000
_llseek(5, 0, [0], SEEK_CUR) = 0
brk(0) = 0x80bb000
brk(0x80c4000) = 0x80c4000
read(5, "root:x:0:root\nbin:x:1:root,bin,d"..., 4096) = 616
read(5, "", 4096) = 0
_llseek(5, 616, [616], SEEK_SET) = 0
read(5, "", 4096) = 0
_llseek(5, 616, [616], SEEK_SET) = 0
read(5, "", 4096) = 0
|
The /etc/group was opened and closed a couple of time before in the execution of this command.
Some ideas? Are there someone with luck that installed this configuration (I mean RedHat 9 and MQSeries 5.3?
I know that there are some issues because the kernel in the RedHat 9 use NTPL.
Regards,

Perhaps you should try creating the "mqm" group and "user" before installing MQSeries, rather than letting MQSeries create them automatically for you...

Thanks for your response, but it didn't work.
Anyway, I am working now with MQ 5.2. I suspect something about the new features of kernel in RedHat 9 (specifically NTPL).

Problem is, that getgrent_r library call used in crtmqm doesn't set errno variable in Redhat 9, and therefore command enters infinite loop. I wrote program, which fixes this problem.
Compile program using
gcc -fPIC -rdynamic -g -c -Wall newgetgrent.c
gcc -shared -WI,-soname,libmy.so.1 -olibmy.so.1.0.1 newgetgrent.o -lc -ldl
and set variable LD_PRELOAD to the full path of libmy.so.1.0.1 library and LD_ASSUME_KERNEL=2.2.5 before issuing an MQ command in my case
export LD_PRELOAD=/tmp/getgrent_r/libmy.so.1.0.1
export LD_ASSUME_KERNEL=2.2.5
crtmqm -q testqm

Vaclav

Hi,
Does anybody know if IBM have the fixes (crtmqm with AMQ8101)for MQ 5.3 for Redhat Linux ?
Thanks!

The crtmqm worked fine after incorporating your fix.
Thanks Vaclav ! |

Finally, the CSD05 fix the trouble ...
Of course, you must use the LD_ASSUME_KERNEL env variable ...
