Error description

  • The MQ 8.0 dmpmqmsg utility in some cases is not copying
    the message data from a queue when using the -i input flag:
    
     dmpmqmsg -m QMGR -i Q1 -f /tmp/Q1.out
    
    The output file contains the message header but not the message
    contents.
    
    Additionally, on some platforms, for example Solaris SPARC, a
    core file may be generated if the -d A display option is used
    with dmpmqmsg. A stack dump of the core file will show the
    failing function to be WriteFileMessageText.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of the dmpmqmsg command on big-endian platforms may be
    affected by this problem
    
    
    Platforms affected:
    AIX, MultiPlatform, Linux on Power, Solaris SPARC, HP-UX
    Itanium, Linux on zSeries, Linux on S390, IBM iSeries, HP-UX
    PA-RISC
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    The dmpmqmsg command has a -i option which should dump the
    contents of a queue to a file. This defect prevented the message
    data of messages on the queue from being dumped.
    

Problem conclusion

  • A coding error was fixed where the input/output variable
    representing the message length that was passed to an MQGET was
    of the wrong type. This meant that on big-endian systems the
    returned length was incorrect.
