Oracle 26ai 2节点RAC 保姆级搭建步骤

Oracle Database 26ai 已于1月28日发布，终于可以在本地安装了。

以下是Oracle 26ai 2节点RAC安装步骤：

相关软件

虚拟机软件：

只是为了测试验证数据库RAC的安装，因此，使用虚拟机来完成RAC安装。

版本，我使用VMware Workstation 17 Pro。

操作系统：

26ai 官方认证是 linux8/9,但想到LINUX10已经发布半年了，现在最新版本是10.1，前面19C也在LINUX10上能安装，因此，选择了Oracle LINUX 10.1,

https://yum.oracle.com/ISOS/OracleLinux/OL10/u1/x86_64/OracleLinux-R10-U1-x86_64-dvd.iso

数据库：
