1、查詢當前被鎖的進程、用戶、對象。
select sess.sid,
sess.serial#,
lo.oracle_username,
lo.os_user_name,
ao.object_name,
lo.locked_mode
from v$locked_object lo, dba_objects ao, v$session sess
where ao.object_id = lo.object_id and lo.session_id = sess.sid;
2、批量KILL進程
declare
v_minutes NUMBER:=1000;
v_Str VARCHAR2(100);
CURSOR C_users(v_minutes number) IS
SELECT s.username,
s.status, s.machine, 'alter system kill session '
||''''||s.sid||','||s.serial# ||'''' operates
FROM v$session s, v$process p
WHERE TYPE = 'USER'
AND p.addr = s.paddr
AND status != 'KILLED'
and exists
(select 1
from dba_ddl_locks a,
v$session b
where a.session_id=b.SID
and b.USERNAME NOT IN ('IFSAPP','AUTOS','THK') --
and b.sid = s.sid)
ORDER BY last_call_et desc;
BEGIN
FOR T_users IN C_users(v_minutes) LOOP
v_Str := T_USERS.OPERATES;
BEGIN
EXECUTE IMMEDIATE v_str;
EXCEPTION
WHEN OTHERS THEN
NULL;
END;
END LOOP;
END;
3、查詢用戶執行時間
select --l.*,o.owner object_owner, o.object_Name,mac.status,mac.osuser,mac.machine
trunc(l.ctime/60,0) mm,(l.ctime/60-trunc(l.ctime/60,0))*60 ss,
l.sid,mac.SERIAL# serial,l.type,mac.osuser,mac.machine,mac.USERNAME user_, o.object_Name,mac.status,
mac.logon_time,'kill -9 '||(select spid from v$process p, v$session s where p.addr=s.paddr and s.sid =mac.sid) spid
,mac.program --,mac.*,o.*
from (select l.* from v$lock l where l.type = 'TM') l,
sys.all_objects o, sys.v_$session mac
where l.id1 = o.object_id
and l.sid = mac.sid;
4、查詢耗時較長的進程
SELECT c.last_call_et, b.value ,c.PROGRAM,c.MACHINE , c.status, c.*,
c.SERIAL#,c.SCHEMANAME,c.TERMINAL
FROM v$statname a,v$sesstat b, v$session c
WHERE a.STATISTIC# =b.STATISTIC#
AND b.sid =c.sid
AND a.name ='CPU used by this session'
AND Value > 100000
ORDER BY Value DESC;
SELECT c.last_call_et, b.value ,c.PROGRAM,c.MACHINE , c.status, c.*,
c.SERIAL#,c.SCHEMANAME,c.TERMINAL
FROM v$statname a,v$sesstat b, v$session c
WHERE a.STATISTIC# =b.STATISTIC#
AND b.sid =c.sid
AND a.name ='consistent gets'
AND Value > 100000000
ORDER BY Value DESC
