1、硬件需求
# grep MemTotal /proc/meminfo
MemTotal: 1035244 kB

# grep SwapTotal /proc/meminfo
SwapTotal: 4192956 kB

# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 141G 2.1G 132G 2% /
/dev/sda1 99M 11M 84M 11% /boot
tmpfs 497M 0 497M 0% /dev/shm

2、内核需求
# uname -a
Linux student 2.6.18-128.el5 #1 SMP Wed Dec 17 11:42:39 EST 2008 i686 i686 i386 GNU/Linux

3、安装需要的系统包
rpm -q gcc-c++ gcc libstdc++-devel glibc-devel glibc-headers libgomp libXp compat-gcc-34 compat-gcc-34-c++ compat-libstdc++-33 sysstat(OEL5 only)

由于缺失的包之间有严格的依赖关系，所以必须按照如下顺序安装缺失的包
rpm -Uvh compat-db-4*
rpm -Uvh libaio-0*
rpm -Uvh compat-libstdc++-33-3*
rpm -Uvh glibc-headers-2.5-12.i386.rpm
rpm -Uvh glibc-devel-2.5-12.i386.rpm
rpm -Uvh compat-gcc-34-3*
rpm -Uvh compat-gcc-34-c++-3*
rpm -Uvh libXp-1*
rpm -Uvh openmotif-2*
rpm -Uvh gcc-4*
rpm -Uvh glibc-2.5-12.i686.rpm
rpm -Uvh libgomp-4.1.1-52.el5.i386.rpm
rpm -Uvh gcc-4.1.1-52.el5.i386.rpm

安装完成后仍然提示部分包没有安装，不过不影响使用
package compat-gcc is not installed
package compat-gcc-c++ is not installed
package compat-libstdc++ is not installed
package compat-libstdc++-devel is not installed

4、修改系统内核参数/etc/sysctl.conf --内核参数配置不正确，在安装软件时检查会提示警告
kernel.shmall = 2097152
kernel.shmmax = 536870912　　
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 = 1048576
net.core.rmem_max = 1048576
net.core.wmem_default = 262144
net.core.wmem_max = 262144
/sbin/sysctl -p

5、修改/etc/hosts文件
127.0.0.1 localhost
192.168.0.176 linux5

6、修改/etc/security/limits.conf
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536

7、修改/etc/pam.d/login
session required /lib/security/pam_limits.so

8、修改/etc/profile
if [ $USER = "oracle" ]; then
ulimit -u 16384
ulimit -n 65536
fi

10、建立用户、组
groupadd oinstall -g 201
groupadd dba -g 202
groupadd oper -g 203
useradd oracle -u 200 -g oinstall -G dba,oper
passwd oracle

11、编辑ORACLE环境变量
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1
export ORACLE_SID=orcl
export PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin:/sbin

12、安装文件上传
将安装文件DBTABASE上传到LINUX系统目录下/home/oracle
# scp database.tar 192.168.0.10:/home/oracle

13、建立目录
mkdir -p /u01/app/oracle
chown -R oracle:oinstall /u01

更改执行权限
# chown –R oracle:oinstall /home/oracle/database
# chmod 775 /home/oracle/database/runInstaller
# chmod –R 775 /home/oracle/database/install

1.1.1.6 执行安装
# XHOST +
{如果是LUNUX机器操作LINUX （192.168.0.173）服务器，在客户端机器上使用命令:
[root@localhost ~]# ssh -X oracle@192.168.0.173
Linux5>xclock
}

# su – oracle
$ ./runInstaller
(如果需要跳过检测，就用$./runInstaller -ignoreSysPrereqs;或者vi /etc/redhat-release
Red Hat Enterprise Linux Server release 5 (Tikanga) 替换成 redhat-4；
如果汉字为乱码，就用 export LANG=en)

安装ORACLE　10.2.0.1 SOFTWARE-->安装10.2.0.4补丁-->dbca安装数据库实例。
