    Thanks for the reply from Darren Dunham and Joe fletcher. It seems that the os
    utility tnsdump is the only solution. I am trying to include it in a
    script,which can give me daily process I/O statistic.

    thanks,

    carl

    :Hello all,
    :
    :With prstat,sar and ps, we can find the CPU usage based on process ID and we
    can
    :kill the process,which hugs the CPU.
    :
    :My question is whether it is possible to retrieve each process I/O usage
    :information, so that we can determine which process creates the I/O bottleneck.
    :I will summarize.
    :
    :thanks,
