1：安装linux时，安装x window system, gnome desktop enviroment,development tools,legacy software development
2：安装完后，，使用rpm -q命令，确保以下包已成功安装：

xorg-x11-deprecated-libs-6.8.2-1.el.13.36.x86_64.rpm
以下几个包也需要安装：
compat-gcc-32-3.2.3-47.3.x86_64.rpm
compat-gcc-32-c++-3.2.3-47.3.x86_64.rpm
compat-libstdc++-33-3.2.3-47.3.x86_64.rpm
yum install binutils compat-db compat-libstdc++ control-center gcc gcc-c++ glibc glibc-common glibc-deve glibc-headers glibc-kernheaders gnome-libs libgcc libstdc++  libstdc++-devel libaio make pdksh sysstat xscreensaver xorg-x11-deprecated-libs compat-gcc-32 compat-libstdc++
3：使用gcc32来替换gcc：
cd /usr/bin/
mv gcc gcc.script
mv g++ g++.script
ln -s gcc32 gcc
ln -s g++32 g++
4：调整os参数要求
1)vi /etc/sysctl.conf , 在行末添加以下内容
#use for oracle
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
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
再运行sysctl -p应用以上参数
2)vi /etc/security/limits.conf 行末添加以下内容
#use for oracle
* soft nproc 2047
* hard nproc 16384
* soft nofile 1024
* hard nofile 65536
3)vi /etc/pam.d/login  行末添加以下内容
session    required    pam_limits.so
4)修改/etc/profile，在最后加入：
if [ $user = oracle ]; then
    if [ $shell = /bin/ksh ]; then
        ulimit -p 16384
        ulimit -n 65536
    else
        ulimit -u 16384 -n 65536
    fi
fi
5：创建oracle用户和组
mkdir -p /u01/oracle
mkdir /u01/oradata
groupadd oinstall
groupadd dba
useradd -d /u01/oracle -g oinstall -g dba oracle
passwd oracle
su - oracle
vi ~/.bash_profile
export oracle_base=/u01/oracle
export oracle_home=$oracle_base/product/10.2.0/db_1
export oracle_sid=db64
export path=/usr/sbin:$path
export path=$oracle_home/bin:$path
#export ld_library_path=$ld_library_path:$oracle_home/lib:/usr/lib:/usr/local/lib
export ld_library_path=$oracle_home/lib:/lib64:/usr/lib64:/usr/local/lib64:/usr/x11r6/lib64/
export classpath=$oracle_home/jre:$oracle_home/jlib:$oracle_home/rdbms/jlib
