Answer 1

You don't need to use capital letter to post the request, it looks as if you were yelling, your thread will be processed just the same as any other thread in the forum.
Installation requirements:
1. Installing required packages
The minimum required packages given here are sufficient only if Linux has been installed without customizing the package selection. This list is based upon a "default-RPMs" installation of RHEL AS/ES 5. Additional RPMs may be needed if a "less-than-default-RPMs" installation of RHEL AS/ES 5 is performed. For more information, please refer to Note 376183.1 "Defining a "default RPMs" installation of the RHEL OS".
The version numbers for these packages given below are the minimum version required. If you have the packages with higher versions than the versions mentioned in below example, you can install the higher version packages.
(i) gcc-c++-4.1.1-52.el5.i386.rpm and all its dependent packages. The dependent packages are
gcc-4.1.1-52.el5.i386.rpm
libstdc++-devel-4.1.1-52.el5.i386.rpm
glibc-devel-2.5-12.i386.rpm
glibc-headers-2.5-12.i386.rpm
libgomp-4.1.1-52.el5.i386.rpm
(ii) libXp-1.0.0-8.i386.rpm
(iii) compat-libstdc++-296-2.96-138.i386.rpm
(iv) compat-libstdc++-33-3.2.3-61.i386.rpm
Install all these packages from the directory Server in CD#2 of RHEL 5 by the single command.
# rpm -ivh gcc-c++-4.1.1-52.el5.i386.rpm gcc-4.1.1-52.el5.i386.rpm
libstdc++-devel-4.1.1-52.el5.i386.rpm glibc-devel-2.5-12.i386.rpm
glibc-headers-2.5-12.i386.rpm libgomp-4.1.1-52.el5.i386.rpm
libXp-1.0.0-8.i386.rpm compat-libstdc++-296-2.96-138.i386.rpm
compat-libstdc++-33-3.2.3-61.i386.rpm
(v) compat-db-4.2.52-5.1.i386.rpm
This package is available in the directory Server in CD#3 of RHEL 5. Install this package by the command
# rpm -ivh compat-db-4.2.52-5.1.i386.rpm
2. Set the kernel parameters
Add the following the lines in the file /etc/sysctl.conf
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
To place these changes into effect, execute the command
# sysctl -p
3. Create Oracle user and groups
# groupadd oinstall
# groupadd dba
# useradd -g oinstall -G dba oracle
# passwd oracle
4. Create the required directories for Oracle Base and change the ownership
For example
# mkdir -p /u01/app/oracle
# chown -R oracle:oinstall /u01/app/oracle
5. Set the session limits for Oracle user
Add the following lines to the /etc/security/limits.conf file
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
Add the following line in the /etc/pam.d/login file
session required pam_limits.so
Add the following lines to the /etc/profile.
if [ $USER = "oracle" ]; then
     if [ $SHELL = "/bin/ksh" ]; then
          ulimit -p 16384
          ulimit -n 65536
     else
          ulimit -u 16384 -n 65536
     fi
fi
6. Configure the Oracle user's environment
Configuring the oracle User's Environment, using the appropriate section of "Oracle® Database Quick Installation Guide 10g Release 2 (10.2) for Linux x86". Note that setting $ORACLE_BASE (not $ORACLE_HOME) in the environment will ease a couple of entries in the Oracle Universal Installer.
For example, if oracle user is using bash shell, and has the home directory as /home/oracle,
The following lines to be added to /home/oracle/.bash_profile
export ORACLE_BASE=/u01/app/oracle
export ORACLE_SID=orcl
unset ORACLE_HOME
7. Invoking OUI
Log in as Oracle user and start installation by any one of the following methods. This is required because Oracle 10.2 expects the OS to be RHEL 3 or RHEL 4.
Method 1:
$ ./runInstaller -ignoreSysPrereqs
Method 2:
Copy the oraparam.ini from the installation source install/oraparam.ini to /tmp directory.
Edit the file /tmp/oraparam.ini
Change the following section :
Before
[Certified Versions]
Linux=redhat-3,SuSE-9,redhat-4,UnitedLinux-1.0,asianux-1,asianux-2
After
[Certified Versions]
Linux=redhat-3,SuSE-9,redhat-4,UnitedLinux-1.0,asianux-1,asianux-2,redhat-5
Now invoke the runInstaller as follows :
$ ./runInstaller -paramFile /tmp/oraparam.ini
