    Help1 Help! The problem with oprofile

    I cannot get any data when opreport
    when I execute opreport I got the problems:
    "opreport error : No sample file found: try running opcontrol --dump
    or specify a session contraining sample files"
    My operation procedure was
    #opcontrol --verbose --start
    I got:
