關於oracle被鎖kill_session問題

開鎖

select object_id,session_id,locked_mode from v$locked_object;--查看數據庫鎖
select b.OWNER ,b.OBJECT_NAME,l.SESSION_ID,l.LOCKED_MODE from v$locked_object l,dba_objects b where b.OBJECT_ID = l.OBJECT_ID;
select t2.username,t2.sid,t2.serial#,t2.logon_time from v$locked_object t1,v$session t2 where t1.SESSION_ID = t2.SID order by t2.LOGON_TIME;--14573
alter system kill session '408,4129';

(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)殺掉對應進程
執行命令：alter system kill session'1025,41';
其中1025爲sid,41爲serial#.
