Oracle 死鎖處理（查看鎖表語句及解鎖）

1.查看當前鎖表的進程

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;

2.查看鎖表語句

SELECT b.sid oracleID,
       b.username 登錄Oracle用戶名,
       b.serial#,
       spid 操作系統ID,
       paddr,
       sql_text 正在執行的SQL,
       b.machine 計算機名
FROM v$process a, v$session b, v$sqlarea c
WHERE a.addr = b.paddr
   AND b.sql_hash_value = c.hash_value 

3.殺鎖

alter system kill session 'sid,seial#';
