Hello,

Below is a query

SELECT SUM (c.VALUE)
        FROM v$session a, v$sesstat c, v$statname d
       WHERE a.SID = c.SID
         AND c.statistic# = d.statistic#
         AND d.NAME = 'CPU used by this session'
         AND a.status = 'ACTIVE';

This query will tell me cpu consumption by individual session. But the question is : what does the value represent? is it a time factor, or just an octal number, i mean, what exactly it is?

I could not find any elaborative reference on this column(or any column under v$sesstat) anywhere in Oracle documentation.

Thanks,
R
