--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';
    
    SELECT 'alter system kill session ''' || SID || ',' || SERIAL# || ''';' FROM v$session t1,v$locked_object t2 WHERE t1.sid = t2.SESSION_ID;
    
    --用这个可以查（可以查看哪台机器哪个用户锁了记录, 其中command是用来杀掉锁住记录的session ）：
    select s.sid,s.machine,o.object_name,l.oracle_username,l.locked_mode, 'ALTER SYSTEM KILL SESSION '''||s.sid||', '||s.serial#||''';' Command from v$locked_object l,v$session s,all_objects o where l.session_id=s.sid and l.object_id=o.object_id;
    
    select V$SESSION.sid,v$session.SERIAL#,v$process.spid, rtrim(object_type) object_type,rtrim(owner) || '.' || object_name object_name, decode(lmode, 0, 'None', 1, 'Null', 2, 'Row-S', 3, 'Row-X', 4, 'Share', 5, 'S/Row-X', 6, 'Exclusive', 'Unknown') LockMode, decode(request, 0, 'None', 1, 'Null', 2, 'Row-S', 3, 'Row-X', 4, 'Share', 5, 'S/Row-X', 6, 'Exclusive', 'Unknown') RequestMode ,ctime, block b, v$session.username,MACHINE,MODULE,ACTION, decode(A.type, 'MR', 'Media Recovery', 'RT','Redo Thread', 'UN','User Name', 'TX', 'Transaction', 'TM', 'DML', 'UL', 'PL/SQL User Lock', 'DX', 'Distributed Xaction', 'CF', 'Control File', 'IS', 'Instance State', 'FS', 'File Set', 'IR', 'Instance Recovery', 'ST', 'Disk Space Transaction', 'TS', 'Temp Segment', 'IV', 'Library Cache Invalida-tion', 'LS', 'Log Start or Switch', 'RW', 'Row Wait', 'SQ', 'Sequence Number', 'TE', 'Extend Table', 'TT', 'Temp Table', 'Unknown') LockType from (SELECT * FROM V$LOCK) A, all_objects, V$SESSION, v$process where A.sid > 6 and object_name<>'OBJ$' and A.id1 = all_objects.object_id and A.sid=v$session.sid and v$process.addr=v$session.paddr;
    
    --同样也是通过写sql从数据字典里查出来。
    -- SELECT-SQL1 功能:检查被加锁的对象

    -- SELECT-SQL2 功能:检查被加锁的对象以及加锁的会话信息
    -- 如果需要手工解除锁,请对照要解锁的对象,记下SESSION_ID,SERIAL# 项,然后运行下面的ALTER-SQL1
    select LOCK_INFO.OWNER||'.'||LOCK_INFO.OBJ_NAME as OBJ_NAME, --// 对象名称(已经被锁住) LOCK_INFO.SUBOBJ_NAME as SUBOBJ_NAME, --// 子对象名称(已经被锁住) SESS_INFO.MACHINE as MACHINE, --// 机器名称 LOCK_INFO.SESSION_ID as SESSION_ID, --// 会话SESSION_ID SESS_INFO.SERIAL# as SERIAL#, --// 会话SERIAL# LOCK_INFO.ORA_USERNAME as ORA_USERNAME, --// ORACLE系统用户名称 LOCK_INFO.OS_USERNAME as OS_USERNAME, --// 操作系统用户名称 LOCK_INFO.PROCESS as PROCESS, --// 进程编号 LOCK_INFO.OBJ_ID as OBJ_ID, --// 对象ID LOCK_INFO.OBJ_TYPE as OBJ_TYPE, --// 对象类型 SESS_INFO.LOGON_TIME as LOGON_TIME, --// 登录时间 SESS_INFO.PROGRAM as PROGRAM, --// 程序名称 SESS_INFO.STATUS as STATUS, --// 会话状态 SESS_INFO.LOCKWAIT as LOCKWAIT, --// 等待锁 SESS_INFO.ACTION as ACTION, --// 动作 SESS_INFO.CLIENT_INFO as CLIENT_INFO --// 客户信息 from ( select obj.OWNER as OWNER, obj.OBJECT_NAME as OBJ_NAME, obj.SUBOBJECT_NAME as SUBOBJ_NAME, obj.OBJECT_ID as OBJ_ID, obj.OBJECT_TYPE as OBJ_TYPE, lock_obj.SESSION_ID as SESSION_ID, lock_obj.ORACLE_USERNAME as ORA_USERNAME, lock_obj.OS_USER_NAME as OS_USERNAME, lock_obj.PROCESS as PROCESS from ( select * from all_objects where object_id in (select object_id from v$locked_object)) obj, v$locked_object lock_obj where obj.object_id=lock_obj.object_id ) LOCK_INFO, ( select SID, SERIAL#, LOCKWAIT, STATUS, PROGRAM, ACTION, CLIENT_INFO, LOGON_TIME, MACHINE from v$session ) SESS_INFO where LOCK_INFO.SESSION_ID=SESS_INFO.SID ;
    
    -- 看清楚了 下面就可以 杀死它了。
    -- ALTER-SQL1 功能:杀死会话(SESSION_ID,SERIAL#),可以手工解除锁
    -- 请手工修改SESSION_ID,SERIAL#为相应值
    -- 注意:本功能慎重使用,有一定的破坏性,该SQL可以断开客户机和服务器的连接
    ALTER SYSTEM KILL SESSION 'SESSION_ID,SERIAL#';
