Error description

  • When performing a parallel build in an IBM Rational ClearCase
    dynamic view under Microsoft Windows, the build may hang
    indefinitely if the MVFSViewAttachMup registry value is set as
    per technote
    http://www.ibm.com/support/docview.wss?uid=swg21405894
    
    This issue is apparently due to lock contention between multiple
    processes executing in the build view.
    
    Workarounds:
    1) Perform a serial build. A build that is not parallel at all
    works correctly in this instance.
    2) Reduce the number of simultaneous parallel tasks. If the
    clearmake build is run with -J 10, try using a smaller -J value.

Problem conclusion

  • The IBM Rational ClearCase Multi-Version File System (MVFS) has
    been modified in versions 8.0.0.09 and 8.0.1.02 so that it no
    longer needs to use the MVFSViewAttachMup registry key.
