Oracle杀死锁进程
先查看哪些表被锁住了:
1、获得sid
select b.owner,
b.object_name,
a.session_id,
a.locked_mode from v$locked_object a,
dba_objects b where b.object_id = a.object_id;
2、获得sid,serial
select b.username, b.sid, b.serial#, logon_time
from v$locked_object a, v$session b
where a.session_id = b.sid
order by b.logon_time;
3、杀死锁进程
alter system kill session 'sid,serial';
如果有ora-00031错误，则在后面加immediate;
alter system kill session '29,5497' immediate；
--杀数据库进程（数据库服务器的机子）
SELECT a.username, c.spid AS os_process_id, c.pid AS oracle_process_id
FROM v$session a, v$process c
WHERE c.addr = a.paddr
and a.sid ='1392'
and a.serial# ='10858';

查找锁定的session
SELECT sn.username,m.SID,sn.SERIAL#, m.TYPE,
DECODE (m.lmode,
0, 'None',
1, 'Null',
2, 'Row Share',
3, 'Row Excl.',
4, 'Share',
5, 'S/Row Excl.',
6, 'Exclusive',
lmode, LTRIM (TO_CHAR (lmode, '990'))
) lmode,
DECODE (m.request,
0, 'None',
1, 'Null',
2, 'Row Share',
3, 'Row Excl.',
4, 'Share',
5, 'S/Row Excl.',
6, 'Exclusive',
request, LTRIM (TO_CHAR (m.request, '990'))
) request,
m.id1, m.id2
FROM v$session sn, v$lock m
WHERE (sn.SID = m.SID AND m.request !=0) --存在锁请求，即被阻塞
OR ( sn.SID =m.SID --不存在锁请求，但是锁定的对象被其他会话请求锁定
AND m.request = 0
AND lmode != 4
AND (id1, id2) IN (
SELECT s.id1, s.id2
FROM v$lock s
WHERE request != 0 AND s.id1 = m.id1
AND s.id2 = m.id2)
)
ORDER BY id1, id2, m.request;
通过数据字典V$SESSION与V$LOCK来了解正在等待锁资源的用户
select a.username,a.sid,a.serial#,b.id1 from v$session a ,v$lockb
Where a.lockwait = b.kaddr;
了解锁住其他用户的用户进程，方法如下：
select a.username,a.sid,a.serial#,b.id1 from v$session a,v$lockb
Where b.id1 in
( select distinct e.id1 from v$session d,v$lock e where d.lockwait =e.kaddr)
And a.sid = b.sid and b.request =0;
