安装Linux时，安装X Window System, GNOME Desktop Enviroment,Development Tools,Legacy Software Development，安装完后，使用

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：
binutils-2.15.92.0.2-21.x86_.rpm
compat-db-4.1.25-9.i386.rpm
compat-db-4.1.25-9.x86_.rpm
compat-libstdc++-33-3.2.3-47.3.i386.rpm
compat-libstdc++-33-3.2.3-47.3.x86_.rpm
control-center-2.8.0-12.rhel4.5.x86_.rpm
gcc-3.4.6-3.x86_.rpm
gcc-c++-3.4.6-3.x86_.rpm
glibc-2.3.4-2.25.i686
glibc-2.3.4-2.25.x86_.rpm
glibc-common-2.3.4-2.25.x86_.rpm
glibc-devel-2.3.4-2.25.i386.rpm
glibc-devel-2.3.4-2.25.x86_.rpm
glibc-headers-2.3.4-2.25.x86_.rpm
glibc-kernheaders-2.4-9.1.98.EL.x86_.rpm
gnome-libs-1.4.1.2.90-44.1.x86_.rpm
libgcc-3.4.6-3.i386.rpm
libgcc-3.4.6-3.x86_.rpm
libstdc++-3.4.6-3.i386.rpm
libstdc++-3.4.6-3.x86_.rpm
libstdc++-devel-3.4.6-3.i386.rpm
libstdc++-devel-3.4.6-3.x86_.rpm
libaio-0.3.105-2.i386.rpm
libaio-0.3.105-2.x86_.rpm
make-3.80-6.EL4.x86_.rpm
pdksh-5.2.14-30.3.x86_.rpm
sysstat-5.0.5-11.rhel4.x86_.rpm
xscreensaver-4.18-5.rhel4.11.x86_.rpm
xorg-x11-deprecated-libs-6.8.2-1.EL.13.36.i386.rpm
xorg-x11-deprecated-libs-6.8.2-1.EL.13.36.x86_.rpm

以下几个包也需要安装：
compat-gcc-32-3.2.3-47.3.x86_.rpm
compat-gcc-32-c++-3.2.3-47.3.x86_.rpm
compat-libstdc++-33-3.2.3-47.3.x86_.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 = 21474838
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=$ORACLE_BASE/product/10.2.0/db_1
export ORACLE_SID=db
export PATH=/usr/sbin:$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=$ORACLE_HOME/lib:/lib:/usr/lib:/usr/local/lib:/usr/X11R6/lib/
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
