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
* 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 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:
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 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 +
Edit the /etc/redhat-release file replacing the current release information (Red Hat Enterprise Linux Server release 5 (Tikanga)) with the following:
redhat-4
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
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=
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.
