oracle鎖表與解鎖表方法

–以下幾個為主要相關表

select

*from v$lock
;select
*from v$sqlarea;
select
*from v$session
;select
*from v$process ;
select
*from v$locked_object;
select
*from all_objects;
select
*from v$session_wait;

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;

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;

select sid,

serial
#, username, osuser from v$session;

select s.sid, s.

serial
#, s.username, s.schemaname, s.osuser, s.process, s.machine,
s.terminal, s.logon_time, l.
type
from v$session s, v$lock l
where s.sid = l.sid
and s.username is
notnull
order
by sid;

任何dml語句其實產生了兩個鎖，乙個是表鎖，乙個是行鎖。

–殺掉程序『 sid,serial#』

alter system kill

session
'210,11562'
;
