Oracle 解決表鎖定的問題

1. 通過v$session，v$locked_object查看誰鎖定了資源
     select t1.sid, t1.serial#, t1.username, t1.logon_time
     from v$session t1 , v$locked_object t2
     where t1.sid = t2.session_id
     order by t1.logon_time

2. 通過alter system kill session 'sid, serial#'把session kill掉
     alter system kill session '6,8'
