環境

  • Liferay DXP 7.1
  • MS SQL Server

解像度

  • "TCP/IP connection to host Failed "エラーは、Liferayが設定されたデータベース(SQL SERVER)に接続しようとしたが、残念ながらDBサーバーが稼働していないか、以下のいずれかの理由で利用できない場合にLiferayログに表示されます
    1) ファイアウォールが受信接続をブロックしている
    2) SQL SERVERがホスト上で稼働していない
    3) 設定したポートが間違っている すなわち それは1433ではありません
  • したがって、問題はLiferayではなく、データベースの方にあるのです。 ネットワークチームとともにデータベースチームと連携することで、データベースサーバーだけでなく、Liferayとデータベースの接続を安定させることができます。
