锁(下)

（2）解锁方法

alter system kill session ‘878,1773‘;    /*878为SID，1773为SERIAL#*/

select /*+ rule */ s.username,

decode(l.type,‘tm‘,‘table lock‘,‘tx‘,‘row lock‘,null) lock_level,

o.owner,o.object_name,o.object_type,

s.sid,s.serial#,s.terminal,s.machine,s.program,s.osuser

from v$session s,v$lock l,dba_objects o

where l.sid = s.sid

and l.id1 = o.object_id(+)

and s.osuser = ‘okf55657‘ and s.username = ‘lbimk_babilon‘

and s.username is not null

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

and a.session_id = 745;

alter system kill session‘767,19132‘;

select a.sid,a.serial#,c.object_name,a.sql_id

from v$session a,v$locked_object b,all_objects c

where a.sid=b.session_id

and b.object_id=c.object_id;

select spid from v$process

where addr = (

select paddr from v$session where sid = 767

);

找到相应的spid后，在后台用命令kill -9 spid杀掉OS进程。
