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
安装过程如下：
