oracle10g_data guard_rman恢復測試出錯_RMAN-06207

事由如下：
   不記如何把以前作的控制檔案備份（主庫上），手工刪除，導致 利用rman恢復總提示如下錯誤：
-bash-3.1$ rman target sys/system@centos auxiliary sys/system

failover to previous backup


然後在主庫進入rman操作如下
rman target sys/system@centos
 1,先驗證主庫備份的有效性
     restore database validate;
     restore archivelog all validate;
 2,list backup of database;
    list copy of database;
    list backupset of database;
    ....同理（對於其它備份物件）
    list backup of controlfile;
    list backup of archivelog;
   
    crosscheck backup of controlfile;--這下子就出來好多無效的控制檔案備份

   哈哈，下來你就可以用delete真正把這些東東，從rman的控制檔案中清除，下次rman在恢復就會再用這些資訊了，以免給你添麻煩
    delete noprompt obsolete;
