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.sessi
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#’
