------------检查CPU使用高的进程----------
select ss.sid,se.command,ss.value CPU ,se.username,se.program ,vp.SPID OS_Processes
from v$sesstat ss, v$session se,v$process vp where
ss.statistic# in
(select statistic#
from v$statname
where name = 'CPU used by this session')
and se.sid=ss.sid
And se.SID=vp.PID
and ss.sid>10
And ss.value >10000
order by ss.value desc

------------查询进程的sql语句----------
select s.sid, event, wait_time, w.seq#, q.sql_text
from v$session_wait w, v$session s, v$process p, v$sqlarea q
where s.paddr=p.addr and
s.sid=&p and
s.sql_address=q.address
