注意事項：1 此處實驗環境為同平臺，同字節序，同版本，源機器和目標機器相同的目錄結構。2 目標機器只需要安裝Oracle數據庫軟件即可。3 第一次利用備份恢復測試環境，之后從源機器拷貝備份到目標機器并在控制文件中注冊，再見行恢復測試。 一 拷貝參數文件備份、控制文件備份、數據文件備份、以及歸檔備份到新主機上 1 rman 連接到源數據庫 [oracle@oracle dbs]$ rman target /Recovery Manager: Release 10.2.0.1.0 - PRoduction on Tue Dec 11 19:02:05 2012Copyright (c) 1982, 2005, Oracle.
