Finding Current High-Consuming CPU SQLs

Question

Hi All,
How do we find SQL's consuming most CPU at the current moment. If I find SQL's from V$SQLAREA and sort descending based on CPU_TIME, it may be idle sessions as CPU_TIME gives the cumulative cpu time. Current high-consuming SQL may not even figure on top if cumulative cpu time is less. I am interested in finding top 10 SQL's at the current moment. Is there a way we find the top consumers of CPU?
Thanks,

Answer 1

you can use top,nmon or topass command at OS level to find out PID consuming maximum CPU and resources .. you can use this PID and qury against
v$sesson , V$process and v$SQL to find out user session and SQL been consuming max CPU time and resources.
select a.username , a.program , to_char(a.LOGON_TIME,'dd-mon-yy:hh24:mi'),c.sql_text from v$session a ,
v$process b , v$sql c where
a.paddr=b.addr and a.sql_id=c.sql_id and b.spid='you OS PID' ;
