1.安装rpm包
nano /v.sh
将下面内容复制进去
#!/bin/bash
rpm -Uvh compat-db-4.2.52-5.1.i386.rpm
rpm -Uvh compat-libstdc++-33-3.2.3-61.i386.rpm
rpm -Uvh make-3.81-3.el5.i386.rpm
rpm -Uvh setarch-2.0-1.1.i386.rpm
rpm -Uvh libgomp-4.4.0-6.el5.i386.rpm
rpm -Uvh libXp-1.0.0-8.1.el5.i386.rpm
rpm -Uvh openmotif-2.3.1-2.el5_4.1.i386.rpm
rpm -Uvh kernel-headers-2.6.18-194.el5.i386.rpm
rpm -Uvh glibc-headers-2.5-49.i386.rpm
rpm -Uvh glibc-devel-2.5-49.i386.rpm
rpm -Uvh compat-gcc-34-3.4.6-4.i386.rpm
rpm -Uvh libstdc++-devel-4.1.2-48.el5.i386.rpm
rpm -Uvh gcc-4.1.2-48.el5.i386.rpm
rpm -Uvh gcc-c++-4.1.2-48.el5.i386.rpm
rpm -Uvh compat-gcc-34-c++-3.4.6-4.i386.rpm
存盘
bash /v.sh
rm -f /v.sh
2.调整内核参数
nano /etc/sysctl.conf
#将原来的# kernel.shmmax和kernel.shmall这两行参数屏蔽
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
# semaphores: semmsl, semmns, semopm, semmni
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default=262144
net.core.rmem_max=262144
net.core.wmem_default=262144
net.core.wmem_max=262144
nano /etc/security/limits.conf --加入以下四行代码
* soft nproc 2047
* hard nproc 16384
* soft nofile 1024
* hard nofile 65536
nano /etc/pam.d/login --加入下面一行代码
session required /lib/security/pam_limits.so
3.增加用户及组
groupadd oinstall
groupadd dba
groupadd oper
useradd -g oinstall -G dba Oracle
passwd oracle
4.伪装操作系统版本，使安装Oracle时，通过操作系统验证。
cp /etc/RedHat-release /etc/redhat-release.bak
nano /etc/redhat-release
替换为如下代码：
redhat-4
