RHEL5.5 64位下安装Oracle 11g 64位安装前置条件（即RPM包）有如下两种方式：

一、RPM方式：安装Oracle所需的全部运行库（在RHEL光驱的Server目录下）

以root登录，执行如下命令：

cd /media/RHEL_5.5\ x86_64\ DVD/Server
rpm -Uvh binutils-2.*
rpm -Uvh compat-libstdc++-33*
rpm -Uvh compat-libstdc++-33*.i386.rpm
rpm -Uvh elfutils-libelf*
rpm -Uvh gcc-4.*
rpm -Uvh gcc-c++-4.*
rpm -Uvh glibc-2.*
rpm -Uvh glibc-common-2.*
rpm -Uvh glibc-devel-2.*
rpm -Uvh glibc-headers-2.*
rpm -Uvh ksh*
rpm -Uvh libaio-0.*
rpm -Uvh libaio-devel-0.*
rpm -Uvh libgomp-4.*
rpm -Uvh libgcc-4.*
rpm -Uvh libstdc++-4.*
rpm -Uvh libstdc++-devel-4.*
rpm -Uvh make-3.*
rpm -Uvh sysstat-7.*
rpm -Uvh unixODBC-2.*
rpm -Uvh unixODBC-devel-2.*
rpm -Uvh numactl-devel-*

二、Yum方式：在线安装

以root账号登录，输入：

cd /etc/yum.repos.d

wget http://public-yum.oracle.com/public-yum-el5.repo

yum install oracle-validated
