oracle 常用解锁脚本

1、查看锁表进程

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;

2、解锁脚本

select 'alter system kill session ''' || side || ',' || seriale || ''';' AA
  from (select b.username, b.sid side, b.serial# seriale, logon_time
          from v$locked_object a, v$session b
         where a.session_id = b.sid
         order by b.logon_time)

3、锁表

--手工锁表：
lock table tablename in row share mode nowait;
--锁定整个表 
LOCK TABLE tablename IN EXCLUSIVE MODE;

4、查看某个时间点之前表数据

select * from tablename as of timestamp to_timestamp('删除时间点','yyyy-mm-dd hh24:mi:ss')
