Oracle object unlock - 表，包，過程，函數

Oracle 對象解鎖-表，包，過程，函數

表解鎖 v$locked_object
V$LOCKED_OBJECT lists all locks acquired by every transaction on the system. It shows which sessions are holding DML locks (that is, TM-type enqueues) on what objects and in what mode.

select p.spid,  
       a.serial#,   
       c.object_name,  
       b.session_id,  
       b.oracle_username,  
       b.os_user_name   
from   v$process p,v$session a, v$locked_object b,all_objects c   
where  p.addr=a.paddr and   
       a.process=b.process and   
       c.object_id=b.object_id 

找到sid,serial#將涉及的session殺掉
alter system kill session 'sid,serial#';

包，過程，函數解鎖dba_ddl_locks
DBA_DDL_LOCKS lists all DDL locks held in the database and all outstanding requests for a DDL lock.
包，過程，函數等被鎖定，可以通過該視圖進行定位於解鎖。

col OWNER for a30
col NAME for a30
Select b.SID,b.SERIAL#,a.OWNER,a.NAME,a.TYPE From dba_ddl_locks a, v$session b  Where a.session_id = b.SID;
alter system kill session 'sid,serial#';

也可以從操作系統中對session進行查殺
Select spid, osuser, s.program   From v$session s, v$process p  Where s.paddr = p.addr and s.sid=(sid);
kill -9 spid
