HibernateでSEQUENCEを使用すると、一意制約違反の原因は何ですか？

以下のコードを使用して、idフィールドの一意のIDを生成しています。先週までは順調でした。 Hibernateインターフェースを使用して一部のエンティティを削除した後、新しいレコードを挿入しようとすると、一意制約違反の例外が発生し始めました。

この問題の原因は何ですか？

@SequenceGenerator(name = "ParamGenerator", sequenceName = "ParamSequence", allocationSize = 1)
public class Param extends IdNameEntity<Long> {

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "ParamGenerator")
    private Long id;

これは削除メソッドです：

@Override
public void delete(final T t) {
    getCurrentSession().delete(t);
}

これはエラーログです：

ようやく問題が見つかりました。

このDBを最初に作成したときに、テストDBからデータを移行しました。
テストDBから転送されたデータはprod dbのシーケンスを使用していないため、シーケンスによって生成されたIDが事前に挿入されたレコードと競合するため、レコードをprod dbに挿入しようとすると、制約違反例外が発生しました。

方法1：シーケンスの開始値を変更する

SQL Developerを使用していると仮定します。

  1. [接続]ウィンドウで、データベースの下の[シーケンス]ノードを展開します。
  2. 「ParamSequence」シーケンスを見つけて右クリックします。
  3. 「編集...」を選択します
  4. 「開始」の値を適切に設定します。 これは、SELECT MAX(ID) FROM PARAM;などのクエリを実行してから、 "Increment"値（1など）を追加することで事前に確認できます。ここでの正確な詳細は、テーブル/フィールド名によって異なります。

...または...

方法2：シーケンスのNEXTVAL値を変更する

NEXTVALの値のみを変更したい場合は、 この答え に卑劣な回避策があります。あなたのコンテキストのために以下をコピーしました：

ALTER SEQUENCE ParamSequence INCREMENT BY 100;
SELECT ParamSequence.NEXTVAL FROM DUAL;
ALTER SEQUENCE ParamSequence INCREMENT BY 1;

おそらくこれはあなたにいくつかのヒントを与えるでしょう：

Oracleシーケンスは、重複した値を生成しないことが保証されています。値が重複している場合は、2つの原因のいずれかが発生しているはずです。かなりあいまいなOracleのバグにぶつかったか、アプリケーションにエラーがあるはずです（つまり、シーケンス値が誤ってキャッシュされている、スレッドセーフではない方法で保存されているなど）。
