# Pre-Requirements for Install Oracle Database Software 11gR2 on RHEL5 #
########################################################################
This Document describes the tasks that you must complete before you start Oracle
Universal Installer (OUI).
This guide contains information required to install Oracle Database 11g Release 2
(11.2) on RHEL5 - for training purpose.
Ensure the compatibility between Oracle Database Software version and release
with OS version, release, and CPU architecture.
<-- Run all below steps by root account with password root123 -->
Network Setup:
--------------
Configure Hostname and IP Address for the machine:
echo "192.168.0.1 oradb-server" >> /etc/hosts
cat /etc/hosts
Check RAM & SWAP:
----------------
Minimum: At least 1.0GB of RAM for install Oracle Database as Standalone Server.
Recommended: 2 GB of RAM or more if you plan to install Oracle Database as
Standalone Server.
free -m
grep MemTotal /proc/meminfo
grep SwapTotal /proc/meminfo
Check TEMP:
-----------
Ensure that you have at least 1GB of space in /tmp.
df -h /tmp
Check Kernel installed:
-----------------------
To determine whether the required kernel is installed, enter the following command:
uname -rm
Kernel Limits /etc/sysctl.conf:
-------------------------------
cp /etc/sysctl.conf /etc/sysctl.conf.bk
cat >> /etc/sysctl.conf << EOF
# Configuring oracle user's environment start here #
kernel.shmmax = 836870912
kernel.shmall = 2097152
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 = 1048576
fs.aio-max-nr = 1048576
fs.file-max = 6815744
EOF
cat /etc/sysctl.conf
Security limits:
----------------
cp /etc/security/limits.conf /etc/security/limits.conf.bk
cat >> /etc/security/limits.conf << EOF
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240
oracle hard stack 32768
EOF
cat /etc/security/limits.conf
cp /etc/pam.d/login /etc/pam.d/login.bk
cat >> /etc/pam.d/login <<EOF
session required pam_limits.so
EOF
cat /etc/pam.d/login
As the root account, create a shell script labeled oracle.sh within /etc/profile.d/
to create the appropriate ulimits for the oracle user.
cd /etc/profile.d
cat >> oracle.sh << EOF
#Setting the appropriate ulimits for oracle user
if [ $USER = "oracle" ]; then
umask 022
if [ $SHELL = "/bin/ksh" ]; then
ulimit -u 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
EOF
cat oracle.sh
Disabled SELinux "Security Enhancement" and Firewall:
-----------------------------------------------------
cp /etc/selinux/config /etc/selinux/config.bk
cat >> /etc/selinux/config << EOF
SELINUX=disabled
EOF
cat /etc/selinux/config
chkconfig iptables off
Check the following Packages installed:
---------------------------------------

Check Disk free:
----------------
- Space requirement for Oracle 11g Release 2 Software:
Enterprise Edition 3.95G - 4.5GB
Standard Edition 3.88G - 4.3GB
- Space requirement for Oracle Database Files: 1.7GB - 2.0GB -- > Creating a
database is always optional with oracle installation. Can be done later.
df -h
df -h /u01
Create OS Account and Groups:
-----------------------------
The Oracle Database software owner is the user 'ORACLE'.
groupadd -g 501 dba
cat /etc/group | grep dba
useradd -u 601 -g dba -G dba -d /home/oracle -s /bin/bash -c "Oracle RDBMS Software
Owner" oracle
passwd oracle
oracle123
id oracle
cat /etc/passwd | grep oracle
Create Directories:
-------------------
mkdir -p /u01/app/oracle
ls -l /u01
ls -l /u01/app
mkdir -p /u01/app/oracle/product/11.2.0/dbhome_1
ls -l /u01/app/oracle
ls -l /u01/app/oracle/product
ls -l /u01/app/oracle/product/11.2.0
chown -R oracle:dba /u01/app/oracle
chmod -R 777 /u01
Make sure the Oracle Database 11g (database software are staged in the following
directories):
-----------------------------------------------------------------------------------
-----------
cd /stage/11.2.0/
ls -l
-rwxr-xr-x 1 root root 1285396902 Jan 27 2014 linux_11gR2_database_1of2.zip

-rwxr-xr-x 1 root root 995359177 Jan 27 2014 linux_11gR2_database_2of2.zip
Switch to oracle OS user's, setup & set the environment variables in the
initialization file (for this example we are using bash shell (.bash_profile)):
-----------------------------------------------------------------------------------
---------------------------------------------------------------------
su - oracle
id
cat >> .bash_profile << EOF
# Configuring oracle user's environment start here #
umask 022

EOF
cat .bash_profile
# Configuring oracle user's environment end here #
env | grep ORA
env | grep PATH
Reboot the machine:
-------------------
exit
reboot
Adjust Network Setting:
-----------------------
From System menu --> Administration --> Network
Select record with Nickname ="eth0.bak"
Click Delete Button, then click Yes.
Select record with Nickname ="eth0"
Click Edit, Select Statically IP Address, in Address Text Box = 192.168.0.1
Click Activate Button, then click Yes.
Close the window.
Reboot the machine:
-------------------
reboot
Ensure Machine Hostname and Network Setting is Working Fine:
