Unpack Files

Unzip the files.
# 11.2.0.1

You should now have a single directory called "database" containing installation files.

Hosts File

The "/etc/hosts" file must contain a fully qualified name for the server.
<IP-address>  <fully-qualified-machine-name>  <machine-name>
For example.

127.0.0.1       localhost.localdomain  localhost
192.168.2.181   ol5-11gr2.localdomain  ol5-11gr2
Oracle Installation Prerequisites

Perform either the Automatic Setup or the Manual Setup to complete the basic prerequisites.
The Additional Setup is required for all installations.

Automatic Setup
If you plan to use the "oracle-validated" package to perform all your prerequisite setup, follow the instructions
at http://public-yum.oracle.com to setup the yum repository for OL, then perform the following command.
# yum install oracle-validated

All necessary prerequisites will be performed automatically.
It is probably worth doing a full update as well, but this is not strictly speaking necessary.
# yum update

Manual Setup
If you have not used the "oracle-validated" package to perform all prerequisites, you will need to manually perform the following setup tasks.

Oracle recommend the following minimum parameter settings.
fs.suid_dumpable = 1
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586
The current values can be tested using the following command.
/sbin/sysctl -a | grep <param-name>

Add or amend the following lines in the "/etc/sysctl.conf" file.
fs.suid_dumpable = 1
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
# semaphores: semmsl, semmns, semopm, semmni
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default=262144
net.core.rmem_max=4194304
net.core.wmem_default=262144
net.core.wmem_max=1048586

Run the following command to change the current kernel parameters.
/sbin/sysctl -p

Add the following lines to the "/etc/security/limits.conf" file.
oracle              soft    nproc   2047
oracle              hard    nproc   16384
oracle              soft    nofile  4096
oracle              hard    nofile  65536
oracle              soft    stack   10240

Install the following packages if they are not already present.
# From Oracle Linux 5 DVD
cd /media/cdrom/Server
rpm -Uvh binutils-2.*
rpm -Uvh compat-libstdc++-33*
rpm -Uvh compat-libstdc++-33*.i386.rpm
rpm -Uvh elfutils-libelf*
rpm -Uvh gcc-4.*
rpm -Uvh gcc-c++-4.*
rpm -Uvh glibc-2.*
rpm -Uvh glibc-common-2.*
rpm -Uvh glibc-devel-2.*
rpm -Uvh glibc-headers-2.*

rpm -Uvh make-3.*
rpm -Uvh sysstat-7.*
rpm -Uvh unixODBC-2.*
rpm -Uvh unixODBC-devel-2.*
rpm -Uvh numactl-devel-*
cd /
eject

Create the new groups and users.
groupadd oinstall
groupadd dba
groupadd oper
groupadd asmadmin
useradd -g oinstall -G dba,oper,asmadmin oracle
passwd oracle

 We are not going to use the "asmadmin" group, since this installation will not use ASM.
Additional Setup
The following setup tasks must be performed regardless of which setup method you used
previously.

Set secure Linux to permissive by editing the "/etc/selinux/config" file, making sure
the SELINUX flag is set as follows.

SELINUX=permissive

Alternatively, this alteration can be done using the GUI tool (Applications > System
Settings > Security Level). Click on the SELinux tab and disable the feature.
If SELinux is disabled after installation, the server will need a reboot for the
change to take effect.

If you have the Linux firewall enabled, you will need to disable or configure it, as
shown here or here.

Create the directories in which the Oracle software will be installed.
mkdir -p /u01/app/oracle/product/11.2.0/db_1
chown -R oracle:oinstall /u01
chmod -R 775 /u01

Login as root and issue the following command.
xhost +<machine-name>

Login as the oracle user and add the following lines at the end of the ".bash_profile"
file, remembering to adjust them for your specific installation.

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

ORACLE_HOSTNAME=ol5-112.localdomain; export ORACLE_HOSTNAME
ORACLE_UNQNAME=DB11G; export ORACLE_UNQNAME
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1; export ORACLE_HOME
ORACLE_SID=DB11G; export ORACLE_SID
PATH=/usr/sbin:$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/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH

Installation
Log into the oracle user. If you are using X emulation then set the DISPLAY environmental variable.
DISPLAY=<machine-name>:0.0; export DISPLAY

Start the Oracle Universal Installer (OUI) by issuing the following command in the database directory.

./runInstaller


Oracle database creation using shell script
