1、查詢出被鎖的表的session_id,和serial#。
select l.session_id sid, s.serial#, l.locked_mode,l.oracle_username,
l.os_user_name,s.machine, s.terminal, o.object_name, s.logon_time
from v$locked_object l, all_objects o, v$session s
where l.object_id = o.object_id
and l.session_id = s.sid
order by sid, s.serial# ;
2、kill session
alter system kill session 'aaa,bbb' -- 其中aaa是上面查詢出的sid,bbb是serial#的值
3、一般上兩個步驟就搞定鎖表了，如果殺不掉，就進入到os級別殺......
select spid, osuser, s.program
from v$session s,v$process p
where s.paddr=p.addr and s.sid=24 （24是上面的sid）
linux下 kill -9 12345(12345為上邊查詢出的spid)
oracle鎖表處理
1 select from v locked object 查出被鎖定的物件，其中object id是物件的id,session id是被鎖定物件有session id 2 select object name,object type from dba objects where object id...
Oracle表鎖死處理
查詢被鎖的表 select from v session where sid in select lockobj.session id from v locked object lockobj left join dba objects objs on lockobj.object id objs....
oracle的鎖表及處理
1.執行一下sql，查詢出被鎖表的session和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.log...
