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

******************************************************************************************************************

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;

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;

ALTER SYSTEM KILL SESSION 'sid, serial#';
