Oracle Preinstallation RPMとは？
Oracleの公式のドキュメントによりますと、
ご使用のLinuxディストリビューションがOracle LinuxまたはRed Hat Enterprise Linuxで、Oracle Linuxサポートを使用している場合は、使用しているリリース用のOracle Preinstallation RPMで、インストール前のほとんどの構成タスクを完了できます。
https://docs.oracle.com/cd/E96517_01/ladbi/about-the-oracle-preinstallation-rpm.html
Oracle Preinstallation RPMは、Oracle Linux NetworkまたはOracle Linux DVDから入手できます。Oracle Preinstallation RPMの使用は必須ではありませんが、クラスタ・サーバーの設定の時間を節約するため、使用をお薦めします。
https://docs.oracle.com/cd/E96517_01/ladbi/about-the-oracle-preinstallation-rpm.html
インストールされると、Oracle Preinstallation RPMでは次の操作が実行されます。
-
Oracle Grid InfrastructureおよびOracle Databaseのインストールに必要な追加のRPMパッケージが自動的にダウンロードおよびインストールされ、依存性が解決されます。
-
oracleユーザーが作成され、そのユーザーのoraInventory(oinstall)およびOSDBA(dba)グループが作成されます。 -
必要に応じて、
sysctl.confの設定、システム起動パラメータおよびドライバ・パラメータの値が、Oracle Preinstallation RPMプログラムの推奨値に基づいて設定されます。 -
ハードリソース制限およびソフトリソース制限を設定します。
-
カーネル・バージョンに応じて、他の推奨パラメータを設定します。

Oracle Preinstallation RPMで追加されるユーザーoracleにパスワードが設定されていない罠
で、
Note:
- The Oracle Database Preinstallation RPM automatically creates the Oracle installation owner and groups. It also sets up other kernel configuration settings as required for Oracle Database installations. If you plan to use job-role separation, then create the extended set of database users and groups depending on your requirements.
⇧「Oracle Database 23c（Free-Developer Release）」を、「WSL 2（Windows SubSystem for Linux 2）」の「Oracle Linux 8.7」にインストールしてるんですが、「oracle」っていうユーザーにパスワード設定した覚えがないんけど、デフォルトパスワードとかあるんかと思いきや、
⇧ 自分でパスワードを設定してくださいってことらしい...
勝手にユーザー追加してくれんのは結構なことなんですが、公式のドキュメントでも一言パスワード設定してください、的な言葉があっても良いとは思いませんか？
安定の不親切、流石はOracleさん、完全なるサイコパスと化してますな...

というわけで、今日もまたOracle Databaseを使う気が失われていくのであった...
ついでに、
⇧ 上記サイト様を参考に、wheelグループなるものに追加。
⇧ 解決と思いきや、今度は、sudo: source: command not found なる別のエラーが出た...
次回に持ち越しで...
毎度モヤモヤ感が半端ない...
今回はこのへんで。
