For Finding sql statements which consumes High CPU

Question

Hai,
Can any help me for finding, which sql statements are comsumes high CPU

Answer 1

generaly:
1. from unix site :
us top command or ps (but this depend on platform) -> use pid in select * from v$process where spid <>
2. from db site
select * from v$sql_area order by buffer_gets desc ;
this can You join with v$session where v$session.sql_address=v$sqlarea.address
and when You wont to see % of os select *spid from v$process where addr=<v$session.paddr>
and then in unix ps -ef | grep <spid>
But point 2 is maybe discutable because also parse is one style how to consume CPU ... etc
In 10g
from AWR dba_hist_osstat -> DBA_HIST_SQLSTAT You can see high usage CPU interval , but this show You not momentaly action , but historical data
momentali from ASH
now I study viraq_sh script ... I thing this answer your question tottally
