Oracle的锁表与解锁
SELECT /*+ rule */ s.username,
decode(l.type,'TM','TABLE LOCK',
'TX','ROW LOCK',
NULL) LOCK_LEVEL,
o.owner,o.object_name,o.object_type,
s.sid,s.serial#,s.terminal,s.machine,s.program,s.osuser
FROM v$session s,v$lock l,dba_objects o
WHERE l.sid = s.sid
AND l.id1 = o.object_id(+)
AND s.username is NOT Null
--kill session语句
alter system kill session'50,492';
\\\
select count(*) from v$locked_object;
select * from v$locked_object;
查看哪个表被锁
select b.owner,b.object_name,a.session_id,a.locked_mode
from v$locked_object a,dba_objects b where b.object_id = a.object_id;
查看是哪个session引起的
1. select b.username,b.sid,b.serial#,logon_time from v$locked_object a,v$session b
where a.session_id = b.sid order by b.logon_time;
杀掉对应进程
执行命令:alter system kill session'1025,41';
