I don't know how to see the top CPU-using thread in Windows, but you can get this from the database if you have TIMED_STATISTICS set to TRUE. Just query v$sesstat and join to v$statname by statistic# looking only for 'CPU used by this session', and find out which sid is using the most CPU BETWEEN QUERIES. Alternately, you can get this info from the same table since instance startup by dividing the statistics value by the total lifetime of the session taken from from v$session. I'll let you make the SQL. -- Jeremiah Wilton http://www.speakeasy.net/~jwilton > >--- Hussain Ahmed Qadri <[EMAIL PROTECTED]> wrote: > > > >> We have a consistent problem of CPU utilization > >> 100%.
