oracle中表被锁，可以用的到
1). 查找出被锁的表
select b.owner,b.object_name,a.session_id,a.locked_mode
from v$locked_object a,dba_objects b
where b.object_id = a.object_id;
select b.username,b.sid,b.serial#,logon_time
from v$locked_object a,v$session b
where a.session_id = b.sid order by b.logon_time;
2). 杀进程中的会话
alter system kill session "sid,serial#";
3)杀掉锁语句
select sess.sid,sess.serial#,lo.oracle_username,lo.os_user_name,ao.object_name,lo.locked_mode,
'alter system kill session ''' || sess.sid|| ',' || sess.serial#||''';' as runsql
from v$locked_object lo,dba_objects ao,v$session sess
where ao.object_id = lo.object_id and lo.session_id = sess.sid;
