RMANでRACを単一インスタンスプロセスに復元する
21967 ワード
RMANでRACを単一インスタンスプロセスに復元する
1、rmanで生産ライブラリをバックアップする-==注意:SEQUENCE、THREAD値の設定
2、バックアップセットをターゲットライブラリにコピーする
cp xxx xxx 3、復元先ライブラリ3.1復元controlfile
3.2バックアップセットを登録し、ターゲットライブラリをmount時に登録する必要がある
3.3データファイルの復元
4、リカバリ先ライブラリ
5、制御ファイルの再構築(redoパスの変更を目的とする)
6、データベースを開く
7、一時表領域の確立
8、後続作業
不要なundoを削除
