Problem summary

  • ****************************************************************
    Users of IBM MQ on the Linux (x86/x86-64) platform who have
    installed an MQExplorer component RPM Fix Pack package:
    where 'xxxx-x.x.x-x' corresponds to the fix pack version, such
    as '8007-8.0.0-7'.
    The version of RPM which is used is also significant.  Older
    versions of RPM such as that supplied with RedHat Enterprise
    Linux (RHEL) v6 did not report the warning messages.  More
    recent operating systems which supply a more recent version of
    RPM do report the warnings, which include the operating system
      SUSE 12
      RHEL 7
      Ubuntu 14.04
    This problem only affects the MQ v8.0 release.
    Platforms affected:
    Linux on x86-64, Linux on x86
    APAR IT08513:
    corrected a problem where the Fix Pack packages on Linux were
    not enabling the new MQExplorer plugins as supplied with the
    v8.0 Fix Packs.
    In doing so, a backup of the default installation location
    was created, such that when the Fix Pack was uninstalled, the
    state of the MQExplorer installation would return to the same
    state as before the Fix Pack was applied.
    However, when the Fix Pack package was being removed, the
    ordering of the restoration of this backup was incorrect.
    The directory (and so also its contents) :
    was removed first.
    The RPM package manager then attempted to remove the files
    corresponding to the Fix Pack package, which included the files
    in /opt/mqm/mqexplorer/eclipse.  However these had already been
    removed by the previous step of the uninstallation process.
    The directory was then restored to the previous contents of this
    directory from the backed up archive.
    By default, older versions of RPM did not report any messages to
    the console listing the missing files in the deleted
    /opt/mqm/mqexplorer/eclipse directory.
    However newer versions of RPM such as that supplied with RedHat
    Enterprise Linux v7 do report warning messages for each file
    which was found to be missing, which produces output of the
    warning: file
    /eclipse/runwithtrace: remove failed: No such file or directory
    for every file which was originally under the directory:
    Other than producing excessive output to the console, there was
    no negative consequence to these warning messages.  RPM is
    warning that the files are missing, as it attempts to remove
    them from the filesystem.

Problem conclusion

  • The MQExplorer Fix Pack uninstall scripts have been updated to
    delete the directory:
    after RPM has had the opportunity to remove the files associated
    with the Fix Pack package, which prevents the warning messages
    from being output by RPM.
    While the problem reported does not affect IBM MQ v9.0, the
    equivalent code change has been included to pro-actively guard
    against introduction of the issue at this release.
    The fix is targeted for delivery in the following PTFs:
    Version    Maintenance Level
    v9.0 CD    9.0.4
    v9.0 LTS
    The latest available maintenance can be obtained from
    'WebSphere MQ Recommended Fixes'
    If the maintenance level is not yet available information on
    its planned availability can be found in 'WebSphere MQ
    Planned Maintenance Release Dates'
