Error description

  • An error was seen when installing an MQ Fix Pack:
    
      WebSphere MQ shared resources associated with the
      installation at '/xxx/xxxxxx/xxxx/xxx' are still
      in use. You must stop all MQ processes, including
      applications, Queue Managers, and Listeners, before
      attempting to install, update or delete the WebSphere
      MQ product.
    
    
    But the debug.out file shows:
    
      amqiclen -v -x return code was: '243', output was:
      Failed while executing the mqm.server.rte.pre_u script
    
    243 in decimal is 0xf3 in hex. This is a truncated (single-byte)
    version of 0x7f3, which in decimal is 2035
    (MQRC_NOT_AUTHORIZED).
    
    Therefore the output saying "shared resources associated ... are
    still in use" is not a correct statement of the root cause of
    the problem.

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users upgrading or installing IBM MQ, in the rare case where
    there is a problem encountered during installation.
    
    
    Platforms affected:
    AIX, Linux on S390, Linux on x86-64, Linux on zSeries, Solaris
    SPARC, Solaris x86-64, Linux on Power
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    There are places in the installer code where amqiclen is run
    (this is an internal MQ program that runs as part of
    installation/uninstallation).
    
    In most cases this means that shared memory segments are still
    in use by running queue managers or their applications.
    
    But in other (rare) cases where there is some other reason for
    the program to fail, the error text should be different, so as
    not to be misleading.
    

Problem conclusion

  • The MQ installer/uninstaller code has been updated to output
    error text that is appropriate to the failure.
