Error description

  • After applying IBM Rational ClearCase fixpack 7.0.1.2 or later
    there can be a degradation in the performance of making
    baselines. This is particularly significant in streams that have
    their foundation
    on the INITIAL baseline of many components and start by
    importing a large number of files.
     (by clearfsimport for example)
    
    
    Steps to Reproduce:
    
    1.  Create, say, 50 new, empty components.
    2.  Create a new project, with foundations on the 50 empty
    components.
    3.  In the integration stream, create an activity, and using
    that one activity create 2,000 or more new files in each
    component.
    4.  Make a fully labelled baseline.
       It is reasonable to expect this to take quite some time.
    5.  Create a new activity.
    6.  Make one new version of one file.
    7.  Make an incremental baseline.
       It is reasonable to expect this to be quite quick, but it
    also takes quite a while.
    
    Workaround:
    
    There is no known workaround for this issue.
