VirtualBox de Oracle11g R2 RAC #13 Tweet
VirtualBox de Oracle11g R2 RACのつづきです。
RACを構成する各ノードの構成ファイルを確認しておきま〜す。
- ハードウェア構成(VMなのでVMの構成も含めて）、ソフトウェア構成など
- Linux (CentOS 5.5 x86_64)のインストール
- Openfiler2.3 x86のインストール
- Openfiler2.3 x86によるiSCSIボリュームの構成
- Oracle RACノードでのiSCSIボリュームの構成 その１、その２、その３
- Oracle所有者、Oracle Grid Infrastructureユーザの作成と関連ディレクトリの作成及び環境変数の設定
- Oracle向けLinuxサーバーの構成（カーネルパラメータの設定）
- Oracle RACノード間リモートアクセスの構成とntpの構成
（sshの構成は念のために行った、多分、実施しなくても大丈夫だと思うけど…ついでなので、ちょいと意地悪な実験をしてみた） - ローカルネームサーバの構成
- Oracle RACノード構成ファイルの確認
- Oracle Automatic Storage Management(ASMLib 2.0.5 x84_64)のインストール及び構成
- Oracle11g R2 11.2.0.1.0 RACインストール事前作業
- Oracle11g R2 11.2.0.1.0 Grid Infrastractureのインストール
- Oracle11g R2 11.2.0.1.0 Database softwareのインストール
- Oracle11g R2 11.2.0.1.0 examplesのインストール
- Oracle Cluster databaseの作成
- Net Serviceの確認
- Oralce Grid InsfastructureとDatabase構成の確認
- Clusterの開始と停止の確認
- 簡単なTransparent Application Failover (TAF)の確認
Oracle RACノード構成ファイルの確認
RACを構成する各ノードの構成ファイルをざっと確認。ここまでの作業でRACを構成する各ノードの構成ファイルは以下のようになっているはず…

Oracle Grid Infrastructureユーザや、Oracle所有者の確認はこちら
念のためにuserとgroupのスナップショットを乗せておきますね。
Openfier側構成(やゾンビセッション抑止などは以前の記事参照のこと）
