Error description

  • The IBM Rational ClearCase Remote Client Command-Line Interface
    (CCRC CLI / rcleartool) was rewritten in version 8.0.0.3 and
    8.0.0.4 to have an expanded feature set compared with prior
    versions of rcleartool. These latest versions have been observed
    to load directory elements and small files slower than the
    graphical CCRC interface or applications built with the CM API.
    
    Steps to reproduce: Load numerous directories and/or small files
    using rcleartool and compare the results to CCRC.
    
    Workaround: The issue affects rcleartool 8.0.0.3 and higher.
    CCRC and the custom applications built with the CM API are not
    affected.

    ****************************************************************
    Measurement of the time taken to load various collections of
    elements into the view show that recent versions of
    rcleartool perform this load noticably slower than the
    graphical CCRC interface or applications built with the CM
    API.  This was a reproducible result, and analysis was done
    to find algorithms which could be improved.
    

Problem conclusion

  • This is fixed in ClearCase 8.0.0.5.
