Oracle锁表及杀进程

--查看被锁的表

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;

--查看哪个用户哪个进程造成死锁

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;

--查看连接的进程

SELECT sid, serial#, username, osuser FROM v$session;

--查出锁定表的sid, serial#

SELECT s.sid, s.serial#, s.username, s.schemaname, s.osuser, s.process, s.machine,
s.terminal, s.logon_time, l.type
FROM v$session s, v$lock l
WHERE s.sid = l.sid
AND s.username IS NOT NULL
ORDER BY sid;

--杀掉进程 sid,serial#

alter system kill session'210,11562';
