RAC 環境に問題があります。RedHat 6、Oracle 11.2.0.4 SEを使用しています。ASM を使用して 2 ノード RAC をセットアップします。
SQL Developerを使用して接続する場合、いずれかのクラスタ・ノードに直接接続するとサービス(dev1.xxxx-dmz.local)に接続できますが、クラスタ名を使用しようとすると次のメッセージが表示されます。
Status : Failure -Test failed: IO Error: The Network Adapter could not establish the connection

誰かが何が問題なのかわかるといいのですが、オンラインで他の人が同様の問題を抱えているのを見ましたが、彼らが投稿した解決策はどれも私には効果がないようです。
ありがとう

この問題は、ファイアウォール ポリシーにより、ポート 1521 経由での VIP アドレスへのアクセスが許可されていないことが原因であることが判明しました。これらの IP は許可されるようになり、問題は解決されました。おかげで バラズ すべての助けのために。
