    with the Configuration checker tool in the Designer.  Even
    though a configuration file is correct, the output from running
    ed.  The second problem is that a   temporary file is left
    behind in DSEngine/UVtemp for every PX  job run.

    ****************************************************************
    

Problem conclusion

  • The underlying mechanism for retrieving output from a
    configuration check and for setting up a PX job run writes its
    data to a capture* temporary file under DSEngine/UVtemp.  On
    Windows, a retry loop was added in this code to handle
    instances where this file is still in use when attempting to
    remove it.  This helps ensure that the entire contents are read
    and that the file is cleaned up.
