using rman to creat oracle10g data guard standby db_with recovery

1,請參上一節，我所述關於利用rman tool to create dg standby示例
2,唯一不同的，請在最終rman指令碼上，新增如下，或者：修正如下：
  run
{--set until scn scn號；--源於主庫的select max(next_change#) from v$database;
   duplicate target database for standby
   nofilenamecheck
   dorecover;
}

3,在主庫生成備庫控制檔案，一定要採用如下指令碼  --此步太重要，我就是因為此步，花一大下午的時間，最終是三思大指導，處結此事，在些感謝三思大師指點！！
    startup mount
     copy current controlfile for standby to '控制檔案備份路徑';
     sql 'alter database open';
     sql 'alter system archive log current';


4,附上我出錯的相關錯誤，供備記：
RMAN> run
2> {set until scn 693020;
3> duplicate target database for standby
4> nofilenamecheck
5> dorecover;
6> }

executing command: SET until clause
using target database control file instead of recovery catalog
