oracle死锁进程及杀死死锁进程

--锁对象查找
SELECT * FROM V$LOCKED_OBJECT;
--找到对应会话
SELECT * FROM V$SESSION WHERE SID=？;
--根据对应SQL_HASH_VALUE查找对应的锁语句
SELECT * FROM V$SQLTEXT WHERE HASH_VALUE=? ORDER BY PIECE ASC;

--查询锁语句及执行动作、KILL session语句
SELECT l.INST_ID,
S.SID,
S.SERIAL# ,
S.MACHINE,
O.OBJECT_NAME,
L.ORACLE_USERNAME,
L.LOCKED_MODE,
'ALTER SYSTEM KILL SESSION ''' || S.SID || ',' ||
S.SERIAL# || '''' COMMAND,
t.SQL_TEXT
FROM gv$LOCKED_OBJECT L, gv$SESSION S, ALL_OBJECTS O, gv$sqltext t
WHERE L.SESSION_ID = S.SID
AND L.OBJECT_ID = O.OBJECT_ID
and s.sql_hash_value=t.hash_value
order by t.sql_id,t.piece ;

----查找锁对象、SESSION 以及操作系统进程ID
select object_name as 对象名称,s.sid,s.serial#,p.spid as 系统进程号
from gv$locked_object l , dba_objects o , gv$session s , gv$process p where l.object_id=o.object_id
and l.session_id=s.sid and s.paddr=p.addr;

--杀死进程
ALTER SYSTEM KILL SESSION '1294,35828';
