ORACLE数据库锁查看与解锁

ORACLE数据库锁查看：

SELECT a.username,decode(b.type,'TM','TABLE LOCK','TX','ROW LOCK',NULL) LOCK_LEVEL,
c.owner,c.object_name,c.object_type,
a.sid,a.serial#,a.terminal,a.machine,a.program,a.osuser
FROM v$session a,v$lock b,dba_objects c
WHERE b.sid = a.sid
AND b.id1 = c.object_id(+)
AND a.username is NOT Null;

而解锁就更简单了

alter system kill session 'sid,serial#';
