Oracle官网提供的虚拟机下载，方便测试和开发环境

我们在开发时需要直接连接发布的数据库有时比较麻烦，而自己安装很麻烦特别是在Linux环境下，各种Linux环境的依赖包有时都需要自己去找。

如下的一些虚拟机是oralce官网已经安装好的Linux环境，直接下载使用即可，这样我们开发或测试等时候可以单机把一些相关的情况都搞定了。 

Pre-Built Developer VMs (for Oracle VM VirtualBox)

Learning your way around a new software stack is challenging enough without having to spend multiple cycles on the install process. Instead, we have packaged such stacks into pre-built Oracle VM VirtualBox appliances that you can download, install, and experience as a single unit. Just downloaded/assemble the files, import into VirtualBox (available for free), import, and go (but not for production use or redistribution)!

Some of these VMs are designed to support Developer Day workshops, and have specific hands on labs embedded in them, but they're available to all.) Be sure to install VirtualBox first.
