如何查询锁表的相关对象

1.查询锁的信息

SELECT A.OWNER 方案名,   
     A.OBJECT_NAME 表名,   
     B.XIDUSN 回滚段号,   
     B.XIDSLOT 槽号,   
     B.XIDSQN 序列号,   
     B.SESSION_ID 锁表SESSION_ID,   
     B.ORACLE_USERNAME 锁表用户名,   
     decode(D.type,   
            'XR',   
             'NULL',   
             'RS',   
             'SS(Row-S)',   
             'CF',   
             'SS(Row-S)',   
             'TM',   
             'TABLE LOCK',   
             'PW',   
             'TABLE LOCK',   
             'TO',   
             'TABLE LOCK',   
             'TS',   
             'TABLE LOCK',   
             'RT',   
             'ROW LOCK',   
             'TX',   
             'ROW LOCK',   
             'MR',   
             'S(Share)',   
             NULL) 锁定方式,   
      C.MACHINE 用户组,   
      C.TERMINAL 机器名,   
      B.OS_USER_NAME 系统用户名,   
      B.PROCESS 系统进程id,   
      DECODE(C.STATUS, 'INACTIVE', '不活动', 'ACTIVE', '活动') 活动情况,   
      C.SERVER,   
      C.SID,
      e.SQL_TEXT,  
      C.SERIAL#,   
      C.PROGRAM 连接方式,   
      C.LOGON_TIME   
 FROM ALL_OBJECTS A, V$LOCKED_OBJECT B, SYS.GV_$SESSION C, v$lock d,v$sqltext E 
WHERE (A.OBJECT_ID = B.OBJECT_ID)   
  AND (B.PROCESS = C.PROCESS)   
  and C.sid = d.sid   
  and B.LOCKED_MODE = D.LMODE  
  and c.SQL_ID=e.sql_id (+)
ORDER BY 1, 2; 

select t2.username,
       t2.sid,
       t2.serial#,
       t3.object_name,
       t2.OSUSER,
       t2.MACHINE,
       t2.PROGRAM,
       t2.LOGON_TIME,
       t2.COMMAND,
       t2.LOCKWAIT,
       t2.SADDR,
       t2.PADDR,
       t2.TADDR,
       t2.SQL_ADDRESS,
       t1.LOCKED_MODE
  from v$locked_object t1, v$session t2, dba_objects t3,v$sql t4
 where t1.session_id = t2.sid
   and t1.object_id = t3.object_id
  --- and t2.SADDR=t4.ADDRESS(+)

   and t2.sql_id=t4.sql_id
 order by t2.logon_time

 

alter system kill session '139, 182'
139 : sid  182 : sertal#

2.查询堵塞者与被堵塞者

SELECT
    s1.username  "WAITING USER"
  , s1.osuser    "OS User"

  , s1.LOGON_TIME "logon time"
  , w.session_id "Sid"
  , p1.spid      "PID"
  , q1.SQL_TEXT  "SQLTEXT"
  , s2.username         "HOLDING User"
  , s2.osuser           "OS User"

  , s2.LOGON_TIME "logon time"
  , h.session_id        "Sid"
  , p2.spid             "PID"
  , q2.SQL_TEXT         "SQLTEXT"
FROM
    sys.v_$process p1
  , sys.v_$process p2
  , sys.v_$session s1
  , sys.v_$session s2
  , dba_locks  w
  , dba_locks  h
  , v$sql q1
  , v$sql q2
WHERE
      h.mode_held      != 'None'
  AND h.mode_held      != 'Null'
  AND w.mode_requested != 'None'
  AND w.lock_type  (+)  = h.lock_type
  AND w.lock_id1   (+)  = h.lock_id1
  AND w.lock_id2   (+)  = h.lock_id2
  AND w.session_id      = s1.sid   (+)
  AND h.session_id      = s2.sid   (+)
  AND s1.paddr          = p1.addr  (+)
  AND s2.paddr        = p2.addr  (+)
  AND s1.SQL_ID=q1.SQL_ID(+)
  AND s2.SQL_ID=q2.SQL_ID(+)
  order by h.session_id

  ;

SELECT WSN.USERNAME,
       WSN.MACHINE,
       WSN.SID,
       WSN.SERIAL#,
       WSL.SQL_TEXT,
       HSN.USERNAME,
