To my knowledge there aren't freely available Oracle instances you can access at your leisure -- there'd be patching and hacking attempts to deal with. I don't see any revenue to gain from it, so it's very unlikely.
However, Oracle provides a free version (Express, currently 10g). If you want an instance you can connect to at your whim, I'd suggest using a Virtual Machine (VM) software so you could create & run a VM, that would use a host OS of your choice, in order to install an Oracle Express instance that you could then connect to. That, or setup a separate box for hosting Oracle from.
您可以从 eDelivery.Oracle.com 轻松获取免费版本的 Oracle XE 它在 Windows 上运行并且安装非常简单。快速测试的绝佳平台。

为什么不尝试使用预构建的 Oracle VM ？
Why not try and use a pre-built Oracle VM ?
据我所知，没有可供您随意访问的免费 Oracle 实例 - 需要应对修补和黑客攻击。我看不到从中获得任何收入，所以可能性很小。
不过，Oracle提供了免费版本（Express，目前为10g）。如果您想要一个可以随意连接的实例，我建议您使用虚拟机 (VM) 软件，以便您可以创建和创建实例。运行一个虚拟机，该虚拟机将使用您选择的主机操作系统，以便安装您随后可以连接到的 Oracle Express 实例。或者设置一个单独的盒子来托管 Oracle。
