Common Trouble Solution--解决锁…

解决锁表

 1.以sys 用户登入查询哪些session 被锁

sql>select
t2.username,t2.sid,t2.serial#,t2.logon_time

    from
v$locked_object t1,v$session t2

    where
t1.session_id=t2.sid order by t2.logon_time;

2.根据sid查询该会话的具体sql语句

sql>select sql_text

    from
v$session a ,v$sqltext_with_newlines b

    
where

    DECODE
(a.sql_hash_value,0 ,prev_hash_value,sql_hash_value)=
b.hash_value  

    and
a.sid=&sid order by piece;

   

3.可以记录 《2》中查询的sql语句，然后kill 该会话。

  sql>alter system kill session
'512,2186';
