SuSE安装oracle 12c报错总结（随时更新）

根据官方文档的参考配置进行设置后，如安装在大内存服务器中，会出现如下错误

oracle:system defined limits for shared memery was misconfiguration

解决方法如下： Edit /etc/sysctl.conf and ensure the following lines are present

kernel.shmall = 18350080
kernel.shmmax = 75161927680
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
