查看数据库被锁的表

1.查看被锁的表

SELECT A.OWNER 方案名,
       A.OBJECT_NAME 表名,
       B.XIDUSN 回滚段号,
       B.XIDSLOT 槽号,
       B.XIDSQN 序列号,
       B.SESSION_ID 锁表SESSION_ID,
       B.ORACLE_USERNAME 锁表用户名,
       decode(D.type,
              'XR',
              'NULL',
              'RS',
              'SS(Row-S)',
              'CF',
              'SS(Row-S)',
              'TM',
              'TABLE LOCK',
              'PW',
              'TABLE LOCK',
              'TO',
              'TABLE LOCK',
              'TS',
              'TABLE LOCK',
              'RT',
              'ROW LOCK',
              'TX',
              'ROW LOCK',
              'MR',
              'S(Share)',
              NULL) 锁定方式,
      
       C.MACHINE 用户组,
       C.TERMINAL 机器名,
       B.OS_USER_NAME 系统用户名,
       B.PROCESS 系统进程id,
       DECODE(C.STATUS, 'INACTIVE', '不活动', 'ACTIVE', '活动') 活动情况,
       C.SERVER,
       C.SID,
       C.SERIAL#,
       C.PROGRAM 连接方式,
       C.LOGON_TIME
  FROM ALL_OBJECTS A, V$LOCKED_OBJECT B, SYS.GV_$SESSION C, v$lock d
 WHERE (A.OBJECT_ID = B.OBJECT_ID)
   AND (B.PROCESS = C.PROCESS)
   and C.sid = d.sid
   and B.LOCKED_MODE = D.LMODE
 ORDER BY 1, 2;

  

2.杀掉这个进程  

  alter system kill session 'sid,serial#';

比如：alter system kill session '1515,3620';
