oracle 11g查询被锁表及解锁

1.查询被锁表

select p.spid,a.serial#, c.object_name,b.session_id,b.oracle_username,b.os_user_name from v$process p,v$session a, v$locked_object b,all_objects c where p.addr=a.paddr and a.process=b.process and c.object_id=b.object_id ;

2.解锁

alter system kill session 'sid,serial#';

例：alert system kill session '20541,173';

3.查看那个用户那个进程照成死锁

select b.owner,b.object_name,l.session_id,l.locked_mode from v$locked_object l, dba_objects b where b.object_id=l.object_id;

4.查看连接的进程

SELECT sid, serial#, username, osuser FROM v$session;
