Vagrant创建Oracle RAC环境示例
利用Vagrant安装Oracle RAC（默认为non-CDB模式），生成2台虚机，耗时约1小时。

可以看到vagrant生成了node1和node2两台虚机：

Current machine states:
node2 running (virtualbox)
node1 running (virtualbox)
This environment represents multiple VMs. The VMs are all listed
above with their current state. For more information about a specific
VM, run `vagrant status NAME`.
两台虚机启动后，32G的电脑内存占用由29%升至69%，消耗内存约13G。
空间方面，两台虚机刚生成时，新增空间占用为vagrant目录下的113G（共享存储）加虚机目录下的6.13G（各自的操作系统），总共约120G。
存储使用了ASM：
[grid@node1 ~]$ asmcmd

如果要使用SQL Developer管理此两RAC示例，则需要连接此两主机的公共IP或SCAN IP，例如192.168.56.111和192.168.56.121。他们定义在文件vagrant.yml中：
$ pwd

有几个地方可以表明其为RAC。见下图，RAC #1表明其为集群中的节点1：
然后就是“数据库状态”中，可以看到有2个实例，即DB193H11和DB193H12：
以及“状态”中的“Oracle主机”标签页：
