Oracle中事务锁(锁住的表、锁住的会话)

今天又学会一招,查看Oracle数据库中由于会话非正常退出而导致的事务锁:

1.查看锁住的表

SELECT b.owner,b.object_name,a.session_id,a.locked_mode
    FROM v$locked_object a ,dba_objects b
    WHERE b.object_id = a.object_id;

2.查看被锁住的会话

SELECT b.username,b.sid,b.serial#,logon_time
    FROM v$locked_object a,v$session b
    WHERE a.session_id = b.sid order by b.logon_time;

3.如果要断开某个会话,执行

  Alter system kill session ‘sid,serial#’
