一. 安装相关包
1.1 在redhat 4 上安装10g 需要如下包：
Required package versions (or later):
binutils-2.15.92.0.2-10.EL4
compat-db-4.1.25-9
control-center-2.8.0-12
gcc-3.4.3-9.EL4
gcc-c++-3.4.3-9.EL4
glibc-2.3.4-2
glibc-common-2.3.4-2
gnome-libs-1.4.1.2.90-44.1
libstdc++-3.4.3-9.EL4
libstdc++-devel-3.4.3-9.EL4
make-3.80-5
pdksh-5.2.14-30
sysstat-5.0.5-1
xscreensaver-4.18-5.rhel4.2
libaio-0.3.96
openmotif21-2.1.30-11.RHEL4.2 (Required only to install Oracle demos. Installation of Oracle demos is not covered by this guide.)
1.2 redhat 5上安装orace 10g 需要
# From RedHat AS5 Disk 1
cd /media/cdrom/Server
rpm -Uvh setarch-2*
rpm -Uvh make-3*
rpm -Uvh glibc-2*
rpm -Uvh libaio-0*
cd /
eject
# From RedHat AS5 Disk 2
cd /media/cdrom/Server
rpm -Uvh compat-libstdc++-33-3*
rpm -Uvh compat-gcc-34-3*
rpm -Uvh compat-gcc-34-c++-3*
rpm -Uvh gcc-4*
rpm -Uvh libXp-1*
cd /
eject
# From RedHat AS5 Disk 3
cd /media/cdrom/Server
rpm -Uvh openmotif-2*
rpm -Uvh compat-db-4*
cd /
eject
我们可以通过下面这个命令来检查， 差那个包就安装哪个包：
rpm -q binutils compat-db control-center gcc gcc-c++ glibc glibc-common /
gnome-libs libstdc++ libstdc++-devel make pdksh sysstat xscreensaver libaio openmotif21
如果少了哪些包，直接在安装盘里找一下，安装上就可以了。
rpm 包安装：
rpm -Uvh *.rpm --force --nodeps
二 下载软件
10G和11G的官网下载地址：
http://www.oracle.com/technology/software/products/database/index.html
kernel.shmall = 2097152
kernel.shmmax = 4294967295
kernel.shmmni = 4096
# semaphores: semmsl, semmns, semopm, semmni
kernel.sem = 250 32000 100 128
fs.file-max = 101365
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586
net.ipv4.ip_local_port_range = 1024 65000
for 11gR2
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 4294967295
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586
注意： 如果已经存在的值大于这个值，就不要修改！
--然后运行下面命令，使上面的设置生效
#/sbin/sysctl -p
参数说明：
kernel.shmall为物理内存除以pagesize;
kernel.shmmax为物理内存的一半;
fs.file-max为512 乘以processes (如128个process则为65536);
net.ipv4.ip_local_port_range/net.core.rmem_default/net.core.rmem_max三个参数设置和官方文档不一样, 这是根据metalink 343431.1 最新要求更改的;
net.ipv4.tcp_rmem/net.ipv4.tcp_wmem两个参数一般情况下无需设置, 除非是在Dataguard/Streams等需很多网络传输情况下;
其它参数根据官方文档要求设置即可.
