SELECT 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;
我这里查询出有一个表被锁了：
2、解锁
--alter system kill session ‘sid, serial#‘ --根据查询出来的锁表记录的SID和SERIAL#来释放session
