Yesterday during testing a server running MQ was rebooted. Now if I issue a simple dspmq I get the following error :
dspmq: error while loading shared libraries: libmqml_r.so: wrong ELF class: ELFCLASS32
Server / MQ details are :
[mqm@waptuvirtual0bb ~]$ uname -a
Linux waptuvirtual0bb 2.6.32-358.6.2.el6.x86_64 #1 SMP Tue May 14 15:48:21 EDT 2013 x86_64 x86_64 x86_64 GNU/Linux
[mqm@waptuvirtual0bb ~]$ dspmqver

BuildType: IKAP - (Production)
Platform: WebSphere MQ for Linux (x86-64 platform)

O/S: Linux 2.6.32-358.6.2.el6.x86_64

Any suggestions? I can't find much through Google. Thanks. |

Probably,
It is trying to load of a 32 bit library, when you need a 64 bit one instead .
So a good check of the Installation directories and the libraries contained may be advisable .
Hope It helps... |

Theoretically it means: your libmqml_r.so is a 32-bit library on your 64-bit operating system. Could you check your lib files, perhaps is there a wrong one in your library path?
Firstly you can check your dspmq command, eg.
| Code: |
$ type dspmq
dspmq is hashed (/opt/mqm/bin/dspmq)
$ file /opt/mqm/bin/dspmq
/opt/mqm/bin/dspmq: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.4, not stripped
$ ldd /opt/mqm/bin/dspmq
linux-vdso.so.1 => (0x00007fffcd18f000)
libmqml_r.so => /opt/mqm/lib64/libmqml_r.so (0x00007ff08ab11000)
libmqmcs_r.so => /opt/mqm/lib64/libmqmcs_r.so (0x00007ff08a6d3000)
libmqxzu_r.so => /opt/mqm/lib64/libmqxzu_r.so (0x00007ff08a49d000)
libmqmr_r.so => /opt/mqm/lib64/libmqmr_r.so (0x00007ff089ec9000)
libmqzi_r.so => /opt/mqm/lib64/libmqzi_r.so (0x00007ff089cec000)

| Many thanks for the help. Linux team has just come to the same conclusion. They are going to do a restore on that node to an image taken a week back. Hopefully that will fix it. |
