1. 세션별 CPU Time, Memory 사용량
 
select s.sid, s.serial#, p.spid as "os pid", s.username, s.module, s.sql_id, event, seconds_in_wait,
st.value/100 as "cpu sec",
round(pga_used_mem/1024/1024) "pga_tot(mb)",
round(pga_used_mem/1024/1024) "pga_per_sess(mb)"
from v$sesstat st, v$statname sn, v$session s, v$process p
where sn.name = 'CPU used by this session' -- cpu
and st.statistic# = sn.statistic#
and st.sid = s.sid
and s.paddr = p.addr
and s.last_call_et < 1800 -- active within last 1/2 hour
and s.logon_time > (SYSDATE - 240/1440) -- sessions logged on within 4 hours
order by st.value

 
 
 
 
2. Client별 Memory 사용량
 
select machine,status,count(*) cnt,
       round(sum(pga_used_mem)/1024/1024) "pga_tot(mb)",
       round(sum(pga_used_mem)/count(*)/1024/1024) "pga_per_sess(mb)"
from v$session s, v$process p
where 1=1
--and s.status='active'
and s.paddr=p.addr
and type <> 'BACKGROUND'
group by machine,status
order by 1
