RMANを使用してスタンバイを作成する
53530 ワード
私が別のプロジェクトを始めている間、私はスタンバイデータベース作成のポストカバーを持っていないと理解しました.
誰もが物事を行う方法を持っていますが、最後に私は1つを作成する必要がありました、これは私がそれをやってしまった方法だった.
プライマリデータベースはRac 1クラスタ( Rad 1 - node 1/Rac 1 - node 2 )でtestとrunと呼ばれます.
スタンバイデータベースはtestdgと呼ばれ、RAC 2クラスタ( RAC 2 NODE 1/RAC 2 - node 2 )で実行されます.
データベースは1つのPDB
12.2バージョンを使用しています.一般的なプロセスはすべてのバージョンに非常に似ていますが、調整する必要があるものはほとんどありません.
DBCAサイレントオプションを使用してテストと呼ばれるプライマリデータベースを作成しましょう
アーカイブモードに変更するには、データベースをマウントする必要があります.
スタンバイredoログについては、常にあなたのredoログよりも1グループ余分に追加することを忘れないでください、また、それらをmulitplexしないでください、あなたはスタンバイパフォーマンスが最善としてであることを確認するように.
我々は2 redoロググループを持っているので、我々は各スレッドの3スタンバイ再試行グループを作成します
あなたが本当にこのDBを使用するつもりであるならば、3
12 c以降、データベースパスワードファイルはASM DiskGroup
インスタンス名をパスワードファイル名、testd 1/test 2に追加し、両方のノードにコピーしてください
そして、リスナーをリロードしてサービスを確認する
pfileは、locateのインスタンス名、testdg 1
まずスタンバイ側でRMANを起動し、ターゲット(プライマリ)を接続し、補助(スタンバイ)する
スクリプト実行中に何か問題が発生した場合は、新しいスタンバイを止めて、以前に行ったようにマウントしないでください
まず、スタンバイデータベースとして追加し、各ノードに2つのインスタンスを追加します.
この時点で、システムはORA - 10458でオープンすることができないかもしれません:スタンバイデータベースは我々がセットアップデータブローカーであるので、回復を必要とします
そのために、Pimary側から接続し、プライマリデータベースの設定を作成し、スタンバイを追加します.
最後のステップとして、設定を有効にする
両方のシステムが準備ができていることを確認する前に妥当性を確認するのは良い考えです
ステップは少し長いです、しかし、一旦彼らを利用するならば、あなたはちょうど他のシステムにプロセスを適応させることができます.
いずれにせよ、これはスタンバイを作成する唯一の方法です.
