同じホストにduplicateデータベースを作成する
source db:dbtest
auxiliary db:dupdb
duplicate databaseでは、auxiliary channelが必要なバックアップおよびアーカイブログにアクセスできるように、新しいDBIDが自動的に割り当てられます.
1.source dbのバックアップ
2.傍受ファイルの変更、静的登録傍受
3.tnsnamesを修正する.oraファイル
4.duplicateデータベースのパラメータファイルinitdupdbを作成する.ora
#その他のパラメータはオプションです
5.auxiliary database(duplicate database)の起動
6.rmanを起動する
7.duplicate database操作の開始
次はduplicateコマンドの実行結果です.
