oracle 锁表、解锁的语句

1、查询锁表

SELECT /*+ rule */ lpad(' ',decode(l.xidusn ,0,3,0))||l.oracle_username User_name, o.owner,o.object_name,o.object_type,s.sid,s.serial#FROM v$locked_object l,dba_objects o,v$session s WHERE l.object_id=o.object_id AND l.session_id=s.sid ORDER BY o.object_id,xidusn DESC;SELECT /*+ rule */ s.username,decode(l.type,'TM','TABLE LOCK','TX','ROW LOCK',NULL) LOCK_LEVEL,o.owner,o.object_name,o.object_type,s.sid,s.serial#,s.terminal,s.machine,s.program,s.osuserFROM v$session s,v$lock l,dba_objects oWHERE l.sid = s.sidAND l.id1 = o.object_id(+)AND s.username is NOT Null;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.actionFROM v$sqlarea a,v$session s, v$locked_object lWHERE l.session_id = s.sidAND s.prev_sql_addr = a.addressORDER BY sid, s.serial#;

2、解锁

alter system kill session '24,111'; (其中24,111分别是上面查询出的sid,serial#)
