source : http://ivan.kartik.sk/oracle/install_ora10gR2_redhat.html

Installation of Oracle 10g Release 2 (10.2.0.1.0) on RedHat EL 3, 4, 5 and (Oracle) Enteprise Linux 4, 5.

This paper (HOWTO) describes step-by-step installation of Oracle 10g R2 database software on RedHat Enterprise Server 3, 4, 5 and (Oracle) Enteprise Linux 4, 5. This article is useful for Centos Linux release 3, 4 and 5 and for White Box Enterprise Linux release 3 and 4. Note that Centos and White Box distributions are not certified by Oracle Corporation.
This article does not cover database creation process, and ASM Instance creation process.

This paper covers following steps:

• Pre-Instalation Tasks
• Download & Install
• Post-Instalation Tasks
• Common Installation Errors

Pre-Instalation Tasks

1. Create oracle User Account

Login as root and create te user oracle which belongs to dba group.

su -
# groupadd dba
# useradd -g dba oracle

2. Setting System parameters
Edit the /etc/sysctl.conf and add following lines:

kernel.shmall = 2097152
kernel.shmmax = 2147483648
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

Note: You need reboot system or execute "sysctl -p" command to apply above settings.

For RedHat (OEL, Centos, WBL) 3 and 4 versions: Edit the /etc/pam.d/login file and add following line:

session required /lib/security/pam_limits.so

For RedHat (OEL, Centos) 5 version: Edit the /etc/pam.d/login file and add following line:

session required pam_limits.so

Edit the /etc/security/limits.conf file and add following lines:

oracle    soft  nproc  2047
oracle    hard  nproc  16384
oracle    soft  nofile  1024
oracle    hard  nofile  65536

3. Creating oracle directories

# mkdir /opt/oracle
# mkdir /opt/oracle/102
# chown -R oracle:dba /opt/oracle

4. Setting Oracle Enviroment
Edit the /home/oracle/.bash_profile file and add following lines:
Use this settings for 32bit (x86) architecture.

ORACLE_BASE=/opt/oracle
ORACLE_HOME=$ORACLE_BASE/102
ORACLE_SID=ORCL
LD_LIBRARY_PATH=$ORACLE_HOME/lib
PATH=$PATH:$ORACLE_HOME/bin

export ORACLE_BASE ORACLE_HOME ORACLE_SID LD_LIBRARY_PATH PATH

Use this settings for 64bit (x86_64) architecture.

ORACLE_BASE=/opt/oracle
ORACLE_HOME=$ORACLE_BASE/102
ORACLE_SID=ORCL
LD_LIBRARY_PATH=$ORACLE_HOME/lib:$ORACLE_HOME/lib32
PATH=$PATH:$ORACLE_HOME/bin

export ORACLE_BASE ORACLE_HOME ORACLE_SID LD_LIBRARY_PATH PATH

Save the .bash_profile and execute following commands for load new enviroment:

cd /home/oracle
. .bash_profile

Download & Install

1. Download and install required .rpm packages

Some additional packages are required for succesful instalation of Oracle software. To check wheter required packages are installed on your operating system use following command: Note: Since RHEL 5 (OEL 5, Centos 5) pdksh package was renamed to ksh

For 32 bit (x86) Linux version:

rpm -q binutils gcc glibc glibc-headers glibc-kernheaders glibc-devel compat-libstdc++ cpp compat-gcc make compat-db compat-gcc-c++ compat-libstdc++ compat-libstdc++-devel setarch sysstat pdksh libaio libaio-devel --qf '%{name}.%{arch}\n'|sort

For 64 bit (x86_64) Linux version:

rpm -q binutils compat-db compat-libstdc++-33 glibc glibc-devel glibc-headers gcc gcc-c++ libstdc++ cpp make libaio ksh elfutils-libelf sysstat libaio libaio-devel setarch --qf '%{name}.%{arch}\n'|sort

Also install packages
yum install  gcc make binutils libaio1 gawk ksh libc6-dev rpm libmotif3 alien lsb-rpm libtool
-- The above made the error go away while linking during software install.
-- Not all will be available for Centos. Got this list from Ubuntu Oracle installation in my blog.


-- Looking at the errors below 
yum install libXp

Required packages for 32bit (x86) architecture:

If some package is not installed then install it from installation media or download it from following locations:
RedHat Enterprise Linux 3 - source packages only
RedHat Enterprise Linux 4 - source packages only
White Box Linux 3
White Box Linux 4
Centos Linux 3
Centos Linux 4
Centos Linux 5


This is example how to build RPM package from source package (libaio-0.3.96-3.src.rpm). Note gcc, make and rpm-build (and dependent) packages must be already installed on your system.

# rpm -ivh libaio-0.3.96-3.src.rpm
# cd /usr/src/redhat/SPECS/
# rpmbuild -bb --target i386 libaio.spec
# cd ../RPMS/i386/

Install the required packages using the rpm command:

# rpm -ivh <package_name>.rpm

2. Download the Oracle 10g release 2 (10.2.0.1.0) software from Oracle website.
Extract the files using following command: For 32bit installation archive

unzip 10201_database_linux32.zip

For 64bit installation archive

gunzip 10201_database_linux_x86_64.cpio.gz
cpio -idmv <10201_database_linux_x86_64.cpio

For RHEL 5, Centos 5: Modify database/install/oraparam.ini file and add "redhat-5" to "Certified Versions" section.
Example:

[Certified Versions]
Linux=redhat-3,SuSE-9,redhat-4,UnitedLinux-1.0,asianux-1,asianux-2,redhat-5

3. Start the Oracle software installation process.

Now the system is prepared for Oracle software installation. To start the installation process execute the following commands:

cd db/Disk1/
./runInstaller

Note: You may get "Warning" status during some pre-requisites checks. This will happen on RH EL 3 where Update 3 or 4 were not installed. You can continue in installation when you simply change the status as "User verified".

Post-Instalation Tasks

1. (Optional) Auto Startup and Shutdown of Database and Listener
Login as root and modify /etc/oratab file and change last character to Y for apropriate database.

ORCL:/opt/oracle/102:Y

As root user create new file "oracle" (init script for startup and shutdown the database) in /etc/init.d/ directory with following content:

#!/bin/bash
#
# oracle Init file for starting and stopping
# Oracle Database. Script is valid for 10g and 11g versions.
#
# chkconfig: 35 80 30
# description: Oracle Database startup script

# Source function library.

. /etc/rc.d/init.d/functions

ORACLE_OWNER="oracle"
ORACLE_HOME="/opt/oracle/102"

case "$1" in
start)
echo -n $"Starting Oracle DB:"
su - $ORACLE_OWNER -c "$ORACLE_HOME/bin/dbstart $ORACLE_HOME"
echo "OK"
;;
stop)
echo -n $"Stopping Oracle DB:"
su - $ORACLE_OWNER -c "$ORACLE_HOME/bin/dbshut $ORACLE_HOME"
echo "OK"
;;
*)
echo $"Usage: $0 {start|stop}"
esac

Execute (as root) following commands (First script change the permissions, second script is configuring execution for specific runlevels):

chmod 750 /etc/init.d/oracle
chkconfig --add oracle --level 0356

2. (Optional) Auto Startup and Shutdown of Enterprise Manager Database Control
As root user create new file "oraemctl" (init script for startup and shutdown EM DB Console) in /etc/init.d/ directory with following content:

#!/bin/bash
#
# oraemctl Starting and stopping Oracle Enterprise Manager Database Control.
# Script is valid for 10g and 11g versions.
#
# chkconfig: 35 80 30
# description: Enterprise Manager DB Control startup script

# Source function library.

. /etc/rc.d/init.d/functions

ORACLE_OWNER="oracle"
ORACLE_HOME="/opt/oracle/102"

case "$1" in
start)
echo -n $"Starting Oracle EM DB Console:"
su - $ORACLE_OWNER -c "$ORACLE_HOME/bin/emctl start dbconsole"
echo "OK"
;;
stop)
echo -n $"Stopping Oracle EM DB Console:"
su - $ORACLE_OWNER -c "$ORACLE_HOME/bin/emctl stop dbconsole"
echo "OK"
;;
*)
echo $"Usage: $0 {start|stop}"
esac

Execute (as root) following commands (First script change the permissions, second script is configuring execution for specific runlevels):

chmod 750 /etc/init.d/oraemctl
chkconfig --add oraemctl --level 0356

3. (Optional) You may consider to use rlwrap for comfortable work with sqlplus and rman utility.
RPM package for RedHat compatible (x86) distribution you can download here.
RPM package for RedHat compatible (x86_64) distribution you can download here.

su -
# rpm -ivh rlwrap*.rpm
# exit
echo "alias sqlplus='rlwrap sqlplus'" >> /home/oracle/.bash_profile
echo "alias adrci='rlwrap rman'" >> /home/oracle/.bash_profile
. /home/oracle/.bash_profile

Common Installation Errors

DISPLAY not set. Please set the DISPLAY and try again. 
Solution: Execute "export DISPLAY=:0.0" when you perform installtion on local machine or "export DISPLAY=:0.0 when you perform installation on remote machine connected over SSH". Don't forget to execute "xhost +" command on client machine.

Exception java.lang.UnsatisfiedLinkError: /tmp/OraInstall2005-07-07_09-40-45AM/jre/1.4.2/lib/i386/libawt.so: libXp.so.6: cannot open shared object file: No such file or directory occurred.. java.lang.UnsatisfiedLinkError: /tmp/OraInstall2005-07-07_09-40-45AM/jre/1.4.2/lib/i386/libawt.so: libXp.so.6: cannot open shared object file: No such file or directory 
Solution: RH 3, WB 3, Centos 3 - Install the XFree86-libs-4.3.0-81.EL.i386.rpm and dependent packages.
RH 4, WB 4, Centos 4 - Install the xorg-x11-deprecated-libs-6.8.2-1.EL.13.6.i386.rpm package.
RH 5, OEL 5, Centos 5 - Install the libXp-1.0.0-8.1.el5.i386.rpm package.

error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory 
Solution: Install libaio and libaio-devel packages. If packages already installed and error still occurs try execute "ldconfig" as root.

Check complete. The overall result of this check is: Failed <<<< 
Solution: Install missing package or set check system parameters (See reason of failure).
