from v$locked_object l,dba_objects o ,v$session s
 
where l.object_id　=　o.object_id and l.session_id=s.sid;

alter system kill session 'sid,serial#';
 
例如：
 
alter system kill session '20,182';

alter system kill session '20,182' immediate;

select spid, osuser, s.program 
from v$session s,v$process p
where s.paddr=p.addr and s.sid=20 --24 為上面的sid

orakill  sid  　spid --sid 數(shù)據(jù)庫實例名  spid 線程id

KILL -9 SPID -- 查到的線程id

--(1)鎖表查詢的代碼有以下的形式：
select count(*) from v$locked_object;
select * from v$locked_object;
--(2)查看哪個表被鎖
select b.owner,b.object_name,a.session_id,a.locked_mode from v$locked_object a,dba_objects b where b.object_id = a.object_id;
--(3)查看是哪個session引起的
select b.username,b.sid,b.serial#,logon_time from v$locked_object a,v$session b where a.session_id = b.sid order by b.logon_time;
--(4)查看是哪個sql引起的
select b.username,b.sid,b.serial#,c.* from v$locked_object a,v$session b,v$sql c where a.session_id = b.sid
and b.SQL_ID = c.sql_id and c.sql_id = ''
order by b.logon_time;
