私のマシン（Linux）でNeo4j 3.2コミュニティ版を実行していて、通常は正常に動作します。 * .dbディレクトリを同僚からコピーしてこの新しいデータストアをポイントした後、データベースはもう開始したくありません。新しい* .dbをコピーした後にNeo4jが起動しない
古いものに再任することによって、すべてが再び機能します。私はすでに他の実行中のインスタンスに対してpgrep neo4jをチェックしましたが、何も見つけられませんでした。
私は私のneo4j.logに次のエラーを取得：

neo4j.confファイルを編集して、 '＃dbms.active_database = graph.db'という行のコメントを外し、' graph.db'を 'bird_molecules.db'に変更してください。最後の行は 'dbms.active_database = bird_molecules.db'です。 –
こんにちは@BrunoPeres、それはまさに私が「データストアを指している」という意味です。そこで、すでにneo4j.confを編集しました。新しいデータストアを使用するようnoe4jを設定するたびに、起動しません。古いものを使用するように戻る設定 - もう一度動作します。 –
