Hello

I'm trying to figure out which sessions use most CPU time. Oracle manual gave me this sql query:

SELECT v.SID, SUBSTR(s.NAME,1,30) "Statistic", v.VALUE FROM V$STATNAME s, V$SESSTAT v
WHERE s.NAME = 'CPU used by this session' AND v.STATISTIC# = s.STATISTIC#

.. but the value of 'CPU used by this session' is always 0 for all sessions. So my question is do I have to do something special to monitor CPU resourses?

The technical details about my environment: OS: Windows 2000 Advanced Server
Oracle 8.1.7.1.1 Standard Edition
The server has 4 processes of which the Oracle process is allowed to use 3...

The manual gave me another question

Regards

/Jonas
