32-bits Oracle Unzip database the files.
# unzip 10201_database_linux32.zip

64-bits Oracle Unzip database the files.

 #  cd /home/oracle/Desktop/
 #  gunzip 10201_database_linux_x86_64.tar.gz
 #  cpio -idm < 10201_database_linux_x86_64.tar.gz

You should now have a single directory containing installation files. Depending on the age of the download this may either be named  "database".

Make network configuration Static, basically System provide DHCP IP Address.
# system-config-network-tui
Here edit the Device---> eth0-----> Uncheck Use DHCP-----> give Static IP---> Netmask-----Default gateway IP..

Hosts File
The "/etc/hosts" file must contain a fully qualified name for the server.

    <IP-address>  <fully-qualified-machine-name>  <machine-name>
   e.g- 192.168.0.14       desktop20.example.com       localhost


Set Kernel Parameters
# vim /etc/sysctl.conf

    #kernel.shmall = 2097152
    #kernel.shmmax = 536870912
    kernel.shmmni = 4096
    # semaphores: semmsl, semmns, semopm, semmni
    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

Setup

Edit the "/etc/redhat-release" file replacing the current release information (Red Hat Enterprise Linux Server release 5 (Tikanga)) with the following:

    redhat-4

Configure your /etc/yum.repos.d/rhel.repo
    [redhat]
    name=rhel6.5
    baseurl=http://192.168.0.254/rhel-6-64
    enabled=1
    gpgcheck=0

Save the file.

#  yum clean all
#  yum list all 
Install the following packages.
rhel5.5 64-bits
    # yum install setarch make glibc compat-libstdc++-33 compat-gcc-34 compat-gcc-34-c++ gcc libXp openmotif compat-db java* -y

Create the new groups and users.

   # groupadd oinstall
   # groupadd dba
   # groupadd oper

   # useradd -g oinstall -G dba,oper -d /home/oracle oracle
   # passwd oracle

Create the directories in which the Oracle software will be installed.

   # mkdir -p /u01/app/oracle/product/10.2.0/db_1
   # chown -R oracle:oinstall /u01
   # chmod -R 775 /u01

Restart the system and switch to the user oracle.

-- Let's see which shell is being used by the user Oracle.
$ echo $SHELL
/bin/bash

Add the following lines at the end of the ".bash_profile" file.
$ vim ~/.bash_profile
   
#ORACLE SETTING
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR

ORACLE_HOSTNAME=desktop2.example.com; export ORACLE_HOSTNAME
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1; export ORACLE_HOME
ORACLE_SID=orcl; export ORACLE_SID
LD_LIBRARY_PATH=$ORACLE_HOME/jdk/jre/i386:$ORACLE_HOME/jdk/jre/lib/i386/server:$ORACLE_HOME/rdbms/lib:$ORACLE_HOME/lib:$LD_LIBRARY_PATH;
export LD_LIBRARY_PATH
PATH=$PATH:$HOME/bin; export PATH
PATH=$ORACLE_HOME/bin:$PATH; export PATH
export username

if [ $USER = "oracle" ]; then
  if [ $SHELL = "/bin/ksh" ]; then
     ulimit -p 16384
     ulimit -n 65536
  else
     ulimit -u 16384 -n 65536

Save the file.
Now run the following command to make these changes effective in the current session of user oracle.

-- for bash shell
$ source ~/.bash_profile



Login as root and issue the following command.
Allow the user oracle to use X server, which it will need to run Oracle Universal Installer.
e.g.~ xhost +<machine-name>
# xhost +SI:localuser:oracle
or, # xhost +

Flush the firewall
#  iptables -F


Installation
Start the Oracle Universal Installer (OUI) by issuing the following command in the database directory.
