1 查看锁表进程SQL语句1： 2 select sess.sid, 3 sess.serial#, 4 lo.oracle_username, 5 lo.os_user_name, 6 ao.object_name, 7 lo.locked_mode 8 from v$locked_object lo, 9 dba_objects ao, 10 v$session sess 11 where ao.object_id = lo.object_id and lo.session_id = sess.sid; 12 13 查看锁表进程SQL语句2： 14 select * from v$session t1, v$locked_object t2 where t1.sid = t2.SESSION_ID; 15 16 杀掉锁表进程： 17 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 18 alter system kill session '738,1429'; 19 20 21 用这个可以查： 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 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 22 ****************************************************************************************************************** 23 SELECT A.OBJECT_ID, B.OBJECT_NAME, A.SESSION_ID, A.ORACLE_USERNAME, A.OS_USER_NAME, A.PROCESS, A.LOCKED_MODE FROM V$LOCKED_OBJECT A, DBA_OBJECTS B WHERE A.OBJECT_ID = B.OBJECT_ID;
