2、描述
在执行root.sh脚本的时候报错
2018/08/29 13:11:49 CLSRSC-400: A system reboot is required to continue installing.
This will affect all new installations of Grid Infrastructure 12.2.0.1 on RedHat Linux or Oracle Linux with RedHat Compatible Kernel (RHCK) 7 or later
3、处理方法
先打补丁再安装,如果已经安装，需要删除安装文件后，先打补丁，再进行安装
例如：
$ ./gridSetup.sh -applyOneOffs /u01/patch/25078431/
Preparing the home to patch...
Applying the patch /u01/patch/25078431/...
Successfully applied the patch.
(Any warnings about X11 that are displayed may safely be ignored)
