Oracle Database: Installation Oracle 10g on rhel5 - Oracle Database 10g Release 2 (10.2.0.1) Installation On Red Hat Enterprise Linux 5 (RHEL5)

In this article I'll describe the installation of Oracle Database 10g Release 2 (10.2.0.1) on Red Hat Enterprise Linux 5 (RHEL5). The article is based on a server installation similar to this, with a minimum of 2G swap, secure Linux disabled and the following package groups installed:

GNOME Desktop Environment
Editors
Graphical Internet
Text-based Internet
Development Libraries
Development Tools
Legacy Software Development
Server Configuration Tools
Administration Tools
Base
Legacy Software Support
System Tools
X Window System

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

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 containing installation files. Depending on the age of the download this may either be named "db/Disk1" or "database".

Hosts File

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

<ip-address>  <fully-qualified-machine-name>  <machine-name>

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     pam_limits.so

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 (System > Administration > Security Level and Firewall). Click on the SELinux tab and disable the feature.

Setup

Install the following packages:

# From RedHat AS5 Disk 1
cd /media/cdrom/Server
rpm -Uvh setarch-2*
rpm -Uvh make-3*
rpm -Uvh glibc-2*
rpm -Uvh libaio-0*
cd /
eject

# From RedHat AS5 Disk 2
cd /media/cdrom/Server
rpm -Uvh compat-libstdc++-33-3*
rpm -Uvh compat-gcc-34-3*
rpm -Uvh compat-gcc-34-c++-3*
rpm -Uvh gcc-4*
rpm -Uvh libXp-1*
cd /
eject

# From RedHat AS5 Disk 3
cd /media/cdrom/Server
rpm -Uvh openmotif-2*
rpm -Uvh compat-db-4*
cd /
eject

Create the new groups and users:

groupadd oinstall
groupadd dba
groupadd oper

useradd -g oinstall -G dba,oper 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

xhost +

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

redhat-4

# 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

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 database directory:

./runInstaller

During the installation enter the appropriate ORACLE_HOME and name then continue installation. For a more detailed look at the installation process, click on the links below to see screen shots of each stage.

Post Installation

Edit the /etc/redhat-release file restoring the original release information:

Red Hat Enterprise Linux Server release 5 (Tikanga)

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
