导地恢复：
rman target /

RMSN>]set dbid xx; (select dbid from v$database)

RMAN> startup nomount pfile='xx';

RMAN> restore controlfile from 'xx';(最小的备份集）

RMAN> alter database mount;

RMAN> catalog start with 'xx';

RMAN> restore database;
这一步完成之后就停止旧库的监听器

]RMAN>recover database until sequence 8503;(alter system archive log current +1)

RMAN>alter database open resetlogs;

V$ARCHIVED_LOG

RMAN> sql 'alter session set nls_date_format="yyyy-mm-dd hh24:mi:ss"';
