select sess.sid, 
    sess.serial#, 
    lo.oracle_username, 
    lo.os_user_name, 
    ao.object_name, 
    lo.locked_mode 
    from v$locked_object lo, 
    dba_objects ao, 
    v$session sess 
where ao.object_id = lo.object_id and lo.session_id = sess.sid;

SELECT * FROM v$lock;
SELECT * FROM v$sqlarea;
SELECT * FROM v$session;
SELECT * FROM v$process ;
SELECT * FROM v$locked_object;
SELECT * FROM all_objects;
SELECT * FROM v$session_wait;

SELECT b.owner, b.object_name, a.session_id, a.locked_mode
  FROM v$locked_object a, dba_objects b
 WHERE b.object_id = a.object_id;


SELECT b.username, b.sid, b.serial#, logon_time
  FROM v$locked_object a, v$session b
 WHERE a.session_id = b.sid
 ORDER BY b.logon_time;

SELECT sid, serial#, username, osuser FROM v$session;

SELECT s.sid, s.serial#, s.username, s.schemaname, s.osuser, s.process, s.machine,
s.terminal, s.logon_time, l.type
FROM v$session s, v$lock l
WHERE s.sid = l.sid
AND s.username ='HDM'
ORDER BY sid;


alter system kill session'210,11562';

DDL LOCK对象查询

Select b.SID,b.SERIAL#,a.*,b.*
  From dba_ddl_locks a, v$session b
 Where a.session_id= b.SID
   And a.name ='&p_name';

进程id查询

select b.SPID,b.*,a.* from v$session a, v$process b where a.PADDR = b.ADDR and  a.status = 'KILLED';

进程kill

（SPID：123456）
 ##查看进程
 ps -ef | grep 123456
 ##杀死进程
 kill -9 12345
