Vagrant创建Oracle RAC环境示例

news 2025/8/2 8:15:20

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：

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：

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：
