12.2.0.1 RAC PDBレベルのFailoverのテスト
10139 ワード
重要な手順:手動でサービス名Aを追加して起動します(デフォルトのサービス名テスト検証でFailoverを実装できません)
完全な手順: 1.確認環境情報 2.手動でサービスを追加し、 を開始 3.テストクライアントがサービス側 に接続する 4.インスタンス1のpdb 1 を閉じる 5.クライアントはサービス側 に再接続する. 6.インスタンス1のpdb 1 の再起動が完了しました.
1.1サービス側情報:
1.2クライアントtnsnames.ora構成:
サービスステータスを表示すると、oraが正常に追加されたことがわかります.orcl.a.svc:
ノード1のサービスを開始すると、インスタンス1のpdb 1が引き上げられる.
テストプロセス全体が完了しました.
[oracle@db90 ~]$ srvctl add service -db orcl -service A -preferred cdb11,cdb12 -pdb pdb1
[oracle@db90 ~]$ srvctl start service -db orcl -service A完全な手順:
1.環境情報の確認
