とうとうでました。Oracle AI Database 26ai オンプレ！
バージョン23cから長らくOracle Cloudのみのリリースが続きましたが、
皆さんお待ちかね オンプレ版登場です！！！
やれること
2026/1/27にリリースされた Oracle AI Database 26ai (EE) を最速インストール！
OCIのComputeでOracle Linux 9環境を作ったデフォルト状態からスタートします。
待ちに待った製品版。とうとう名前からFreeがとれました！
環境
・Oracle Linux 9 (OCI)
・Oracle AI Database 26ai Enterprise Edition
・作業するOSユーザ：root
手順で実施できること
・手順内で OSユーザ「oracle」が作成される
・Oracle AI DatabaseのS/Wがインストールされる
・データベース「ORCLCDB」が作成される。PDB名は「ORCLPDB1」
・リスナーがポート「1521」で作成される
・SQL*Plusが使えるようになる。
※テスト用の環境を素早く作成することを目的としています。

0．26aiインストールファイルのダウンロード
今回はLinux9用の「oracle-ai-database-ee-26ai-1.0-1.el9.x86_64.rpm」をダウンロードしました。
https://www.oracle.com/database/technologies/oracle26ai-linux-downloads.html
ダウンロードしたファイルはComputeの/tmpに配置します。
