Error description

  • After installing and uninstalling an MQ fixpack level between
    8.0.0.4 - 8.0.0.8 (inclusive)
    the following symbolic links remain on lib64 directory.
    
    lrwxrwxrwx. 1 mqm mqm 35  Sep 21 15:53 libicudata.so.48 ->
    /opt/mqm/lib64/libicudata.so.48.1.1
    lrwxrwxrwx. 1 mqm mqm 35  Sep 21 15:53 libicui18n.so.48 ->
    /opt/mqm/lib64/libicui18n.so.48.1.1
    lrwxrwxrwx. 1 mqm mqm 33  Sep 21 15:53 libicuuc.so.48 ->
    /opt/mqm/lib64/libicuuc.so.48.1.1

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users who have applied at least one of the following MQ fix
    packs on Linux:
    
    8.0.0.4
    8.0.0.5
    8.0.0.6
    8.0.0.7
    8.0.0.8
    
    
    Platforms affected:
    Linux on x86-64, Linux on Power, Linux on x86, Linux on S390,
    Linux on zSeries
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    A logic error in the fix pack uninstallation code included with
    the levels listed above meant that some symbolic links were not
    removed during unintstallation.
    

Problem conclusion

  • From fix pack 8.0.0.9, the problem has been addressed. However,
    as the affected code is present within the fix pack bundles
    themselves, the issue cannot be resolved for installations where
    the affected fix packs have already been applied, and manual
    cleanup will be required.
    
    It is not required to apply MQ fix packs sequentially, and so
    users performing new installations may apply the latest,
    unaffected, fix pack to their base installation.
    
    The affected symbolic links are:
    
    /opt/mqm/lib64/libicudata.so.48 ->
    /opt/mqm/lib64/libicudata.so.48.1.1
    /opt/mqm/lib64/libicui18n.so.48 ->
    /opt/mqm/lib64/libicui18n.so.48.1.1
    /opt/mqm/lib64/libicuuc.so.48 ->
    /opt/mqm/lib64/libicuuc.so.48.1.1
    
    This information has been documented in the MQ version 8 readme.
    These symbolic links can be manually removed after uninstalling
    IBM MQ V8 if these files exist on Linux platforms.
    
    ---------------------------------------------------------------
