ORACLE 存儲過程解及表解鎖和停止執行

查看進程:

select * from v$process

 

根據存儲過程名稱查找是否被鎖：

select * FROM dba_ddl_locks where name =upper('sp_1');

select * FROM dba_ddl_locks where name like upper('%sp_1%');

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  s.*
from v$locked_object l, dba_objects o, v$session s, v$process p
 where l.object_id = o.object_id
   and l.session_id = s.sid
   and s.paddr = p.addr
   AND object_name= upper(''表或存儲過程名字'）;

　　

 

查找SID:

select t.sid,t.serial# from v$session t
where t.sid=550;

 

殺session解鎖:

alter system kill session '550,10047' immediate;

--sid,t.serial#

 

如果利用上面的命令殺死一個進程后，進程狀態被置為"killed"，但是鎖定的資源很長時間沒有被釋放，那么可以在os一級再殺死相應的進程（線程），首先執行下面的語句獲得進程（線程）號：
select spid, osuser, s.program from v$session s,v$process p where 
s.paddr=p.addr and s.sid=550 

(550就是上面的sid)

 

單機：
SELECT A.PID, B.SID, B.SERIAL#, C.SQL_TEXT,A.SPID
  FROM V$PROCESS A, V$SESSION B, V$SQLAREA C
 WHERE A.ADDR = B.PADDR
   AND B.SQL_ADDRESS = C.ADDRESS

rac:

SELECT A.PID, B.SID, B.SERIAL#, C.SQL_TEXT,A.SPID
  FROM GV$PROCESS A, GV$SESSION B, GV$SQLAREA C
 WHERE A.ADDR = B.PADDR
   AND B.SQL_ADDRESS = C.ADDRESS

再到linux下 kill -9 pid

 

 

殺會話

select  a.USERNAME,a.MACHINE, sql_text,'alter system kill session '''||a.SID||','||a.SERIAL#||',@'||a.INST_ID||'''immediate;' ,status 
from gV$session a inner join GV$sql b on a.sql_id=b.sql_id 
WHERE status = 'ACTIVE'

 

定時任務，殺掉特定服務器上執行超過一個小時的語句

create or replace procedure ks_kill_sp_timeout
