Oracle之锁表问题

查找用户锁

select   s.username, 
decode(l.type, 'TM ', 'TABLE   LOCK ', 
                            'TX ', 'ROW   LOCK ', 
                            NULL)   LOCK_LEVEL, 
o.owner,o.object_name,o.object_type,s.terminal,s.machine,s.program,s.osuser 
from   v$session   s,v$lock   l,dba_objects   o 
where   s.sid=l.sid 
and   o.object_id=l.id1 
and   s.username   is   not   null 

 

查找锁等待

select   lpad( '',decode(l.xidusn,0,3,0))||l.oracle_username   User_name, 
              o.owner,o.object_name,o.object_type 
from   v$locked_object   l,dba_objects   o 
where   l.object_id=o.object_id 
order   by   o.object_id   desc 

 

找出相应的

alter   system   kill   session   'sid,   serial# '   
or 
alter   system   disconnect   session   'sid,   serial# '   immediate;
