OracleDatabase oracle oracle19c oracle テキストリンク

現在のOracle Databaseは四半期ごとの集積パッチをRelease Update (RU)、Release Update Revisions (RUR) という形で提供しています。
詳細は以下をご参照ください。
Oracle Database 最新情報と年次リリースモデルに関して
上記資料にもある通り、RUとRURは柔軟に行き来ができる仕様となっています。
と言うものの、実際に試したことがなかったのでやってみました。

前提条件

OS: Oracle Linux 7.9
DB構成: シングル・インスタンス
初期DBバージョン: RUR 19.12.2

検証シナリオ

RUR 19.12.2 のDBを作成
RU 19.14 を適用
再度RUR 19.12.2 にロールバック

実施結果

結論としては問題なくRUとRURを行き来できました。
以降は詳細手順を載せていきます。

RUR 19.12.2 ⇒ RU 19.14 の適用

opatchで適用済みパッチがRUR 19.12.2 であることを確認。

RU 19.14 ⇒ RUR 19.12.2 にロールバック

ロールバックの際はopatchのrollbackコマンドで戻します。
試しにopatch applyでRUR 19.12.2の適用を試みたところ、すでに適用されているので何もしません、と返ってきました。
まぁ当たり前ですね。。

あとは以下の手順を実行しますが、詳細は割愛します。

まとめ

以上の通り、RUとRURは柔軟に行き来できました。
｢当初はRURを適用して脆弱性対応やリグレッション修正のみ考慮していたけれども、やっぱりRU適用したくなった！」というケースに対して柔軟に対応できるので安心ですね。
ちなみに集積パッチの適用の仕方としては、RURではなく、定期的にRUを適用していくのがお勧めです（含まれるバグ修正の数が全然違いますので...）。
RUにはオプティマイザ修正も含まれますが、デフォルトで無効化されていますので、その点はご安心ください。
