获取23c开发者版
简单介绍可参考这里。
获取数据库可以参考这篇文章Introducing Oracle Database 23c Free -- Developer Release或这里。
Docker Image
这是最快的方法。在OCI上创建一个计算实例，然后就可以拉取image使用了。
docker的安装和配置不赘述了。
拉取image：
bash
$ docker pull container-registry.oracle.com/database/free
Using default tag: latest
Trying to pull repository container-registry.oracle.com/database/free ...

Version 23.2.0.0.0Vagrant Box
如果要离线用，Vagrant Box是一个不错的选择。
简介看这里。
和其它版本的Oracle不同，开发者版不需要预先下载安装介质，其实也没得可下。因此网速就很重要。
安装日志如下：

需要安装Virtual Box，其实上一个Vagrant Box也是需要的。下载页面见这里。
大小约7G，因为是图形界面的，可能会比Vagrant Box要慢一点点。
