Oracleデータベースの障害後に永続性ユニットに再接続する方法

Question

残念ながらOracleデータベースを再起動する必要があります（障害発生後、または何らかの理由で）。私のパーシスタンスユニットはデータベースに再接続できません。ここで

のEclipseLinkはGlassfishの3.1.1とのJDBC接続プールで使用されています。 データベースへの接続が失われた後、プールが自動的に再接続する便利な方法を知っていますか？

Answer 1

私は問題がEclipseLinkによってではなく、あなたが使用しているglassfish接続プールによって発生していると思います。

プールがが /無効とまだあなたのアプリケーション/のEclipseLinkに戻す閉じているその接続することを認識していないように思われます。

このプールは一度も設定されていませんが、接続プール内でkeep alive/verification機能を有効にする方法については、ドキュメントを参照してください。 これにより、プールがアイドル状態の接続を定期的にテストし、無効/クローズとして検出された場合に削除/更新されます。
