oracle锁表该如何解决_oracle_

 select object_name,machine,s.sid,s.serial# from v$locked_object l,dba_objects o ,v$session s where l.object_id　=　o.object_id and l.session_id=s.sid;

 alter system kill session 'sid,serial#'; 例如： alter system kill session '20,182';

 alter system kill session '20,182' immediate;

 select spid, osuser, s.program from v$session s,v$process p where s.paddr=p.addr and s.sid=20 --24 为上面的sid

 orakill sid 　spid --sid 数据库实例名 spid 线程id

 KILL -9 SPID -- 查到的线程id

 --(1)锁表查询的代码有以下的形式： select count(*) from v$locked_object; select * from v$locked_object; --(2)查看哪个表被锁 select b.owner,b.object_name,a.session_id,a.locked_mode from v$locked_object a,dba_objects b where b.object_id = a.object_id; --(3)查看是哪个session引起的 select b.username,b.sid,b.serial#,logon_time from v$locked_object a,v$session b where a.session_id = b.sid order by b.logon_time; --(4)查看是哪个sql引起的 select b.username,b.sid,b.serial#,c.* from v$locked_object a,v$session b,v$sql c where a.session_id = b.sid and b.SQL_ID = c.sql_id and c.sql_id = '' order by b.logon_time;
