oracle解锁

查看锁表进程SQL语句1：
select sess.sid,
    sess.serial#,
    lo.oracle_username,
    lo.os_user_name,
    ao.object_name,
    lo.locked_mode
    from v$locked_object lo,
    dba_objects ao,
    v$session sess
where ao.object_id = lo.object_id and lo.session_id = sess.sid;

查看锁表进程SQL语句2：
select * from v$session t1, v$locked_object t2 where t1.sid = t2.SESSION_ID;

杀掉锁表进程：
如有記錄則表示有lock，記錄下SID和serial# ，將記錄的ID替換下面的738,1429，即可解除LOCK
alter system kill session '738,1429';

========================================

我写的脚本，有点慢，将就着用吧
--kill session语句
alter system kill session'50,492';

--以下几个为相关表
SELECT * FROM v$lock;
SELECT * FROM v$sqlarea;
SELECT * FROM v$session;
SELECT * FROM v$process ;      
SELECT * FROM v$locked_object;   
SELECT * FROM all_objects;   
SELECT * FROM v$session_wait;


--1.查出锁定object的session的信息以及被锁定的object名
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.查出锁定表的session的sid, serial#,os_user_name, machine name, terminal和执行的语句
--比上面那段多出sql_text和action
SELECT l.session_id sid, s.serial#, l.locked_mode, l.oracle_username, s.user#,
       l.os_user_name,s.machine, s.terminal,a.sql_text, a.action  
     FROM v$sqlarea a,v$session s, v$locked_object l
    WHERE l.session_id = s.sid
      AND s.prev_sql_addr = a.address
ORDER BY sid, s.serial#;
      
--3.查出锁定表的sid, serial#,os_user_name, machine_name, terminal，锁的type,mode
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;
