Oracle Database 10g Release 2 (10.2.0.1) Installation On RedHat Advanced Server 4.0
In this article I'll describe the installation of Oracle Database 10g Release 2 (10.2.0.1) on RedHat Advanced Server 4.0. The article is based on a server installation with a minimum of 2G swap, secure Linux disabled and the following package groups installed:

• X Window System
• GNOME Desktop Environment
• Editors
• Graphical Internet
• Text-based Internet
• Server Configuration Tools
• Development Tools
• Administration Tools
• System Tools

Alternative installations may require additional packages to be loaded in addition to the ones listed below.

• Download Software
• Unpack Files
• Hosts File
• Set Kernel Parameters
• Setup
• Installation
• Post Installation

Download Software

Download the following software:

• Oracle Database 10g Release 2 (10.2.0.1) Software

Unpack Files

Unzip the files:

unzip 10201_database_linux32.zip

You should now have a single directory (db/Disk1) containing installation files.

Hosts File

The /etc/hosts file must contain a fully qualified name for the server:

Set Kernel Parameters

Add the following lines to the /etc/sysctl.conf file:

kernel.shmall = 2097152
kernel.shmmax = 2147483648
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

Run the following command to change the current kernel parameters:

/sbin/sysctl -p

Add the following lines to the /etc/security/limits.conf file:

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

Add the following line to the /etc/pam.d/login file, if it does not already exist:

session    required     /lib/security/pam_limits.so

Note by Kent Anderson: In the event that pam_limits.so cannot set privilidged limit settings see Bug 115442.

Disable secure linux by editing the /etc/selinux/config file,
making sure the SELINUX flag is set as follows:

SELINUX=disabled

Alternatively, this alteration can be done using the GUI tool (Applications > System Settings > Security Level). Click on the SELinux tab and disable the feature.

Setup

Install the following packages:

# From RedHat AS4 Disk 2
cd /media/cdrom/RedHat/RPMS
rpm -Uvh setarch-1.6-1.i386.rpm
rpm -Uvh compat-libstdc++-33-3.2.3-47.3.i386.rpm
rpm -Uvh make-3.80-5.i386.rpm
rpm -Uvh glibc-2.3.4-2.i386.rpm

# From RedHat AS4 Disk 3
cd /media/cdrom/RedHat/RPMS
rpm -Uvh openmotif-2.2.3-6.RHEL4.2.i386.rpm
rpm -Uvh compat-db-4.1.25-9.i386.rpm
rpm -Uvh libaio-0.3.102-1.i386.rpm
rpm -Uvh gcc-3.4.3-9.EL4.i386.rpm

# From RedHat AS4 Disk 4
cd /media/cdrom/RedHat/RPMS
rpm -Uvh compat-gcc-32-3.2.3-47.3.i386.rpm
rpm -Uvh compat-gcc-32-c++-3.2.3-47.3.i386.rpm

Create the new groups and users:

groupadd oinstall
groupadd dba
groupadd oper

useradd -g oinstall -G dba 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

Login as root and issue the following command:

xhost +

Login as the oracle user and add the following lines at the end of the .bash_profile file:

# Oracle Settings
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR

ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1; export ORACLE_HOME
ORACLE_SID=TSH1; export ORACLE_SID
ORACLE_TERM=xterm; export ORACLE_TERM
PATH=/usr/sbin:$PATH; export PATH
PATH=$ORACLE_HOME/bin:$PATH; export PATH

LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
export CLASSPATH
#LD_ASSUME_KERNEL=2.4.1; export LD_ASSUME_KERNEL

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

Installation

Log into the oracle user. If you are using X emulation then set the DISPLAY environmental variable:

DISPLAY=:0.0; export DISPLAY

Start the Oracle Universal Installer (OUI) by issuing the following command in the Disk1 directory:

./runInstaller

During the installation enter the appropriate ORACLE_HOME and name then continue installation.

Post Installation

Edit the /etc/oratab file setting the restart flag for each instance to 'Y':

TSH1:/u01/app/oracle/product/10.2.0/db_1:Y

Create a file called /etc/init.d/dbora containing the following:

#!/bin/sh
# description: Oracle auto start-stop script.
# chkconfig: - 20 80
#
# Set ORA_HOME to be equivalent to the $ORACLE_HOME
# from which you wish to execute dbstart and dbshut;
#
# Set ORA_OWNER to the user id of the owner of the 
# Oracle database in ORA_HOME.
ORA_HOME=/u01/app/oracle/product/10.2.0/db_1
ORA_OWNER=oracle
if [ ! -f $ORA_HOME/bin/dbstart ]
then
    echo "Oracle startup: cannot start"
    exit
fi
case "$1" in
    'start')
        # Start the Oracle databases:
        # The following command assumes that the oracle login 
        # will not prompt the user for any values
        su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl start"
        su - $ORA_OWNER -c $ORA_HOME/bin/dbstart
        ;;
    'stop')
        # Stop the Oracle databases:
        # The following command assumes that the oracle login 
        # will not prompt the user for any values
        su - $ORA_OWNER -c $ORA_HOME/bin/dbshut
        su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl stop"
        ;;
esac

Use chmod to set the privileges to 750:

chmod 750 /etc/init.d/dbora

Link the file into the appropriate run-level script directories:

ln -s /etc/init.d/dbora /etc/rc0.d/K10dbora
ln -s /etc/init.d/dbora /etc/rc3.d/S99dbora

Associate the dbora service with the appropriate run levels:

chkconfig --level 345 dbora on

The relevant instances should now startup/shutdown automatically at system startup/shutdown.
