kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000

三 生问题后,搜索了很多网上的资源,其中发现竟然有很多我都遇到了和我相同的问题,于是,通过ORACLE安装光盘,打开ORACLE提供的标准安装文档(该文档NNNN多内容,所以一开始并没有仔细看),仔细看了文档关于网络环境的配置,终于找到了解决方法,并在实际环境测试通过:
以ROOT用户进入,修改/ETC/HOSTS文件的以下内容:
127.0.0.1 localhost.localdomain localhost

xxxx.xxxx.xxxx.xxxx xxxx.com xxxx

注:xxxx.xxxx.xxxx.xxxx是本地IP地址 xxxx.com是本地的域名全名,使用hostname命令取出 xxxx是域名简写
