In this post, I’m going to demonstrate to you how to install ORACLE 12c Release 1 (12.1) on ORACLE LINUX-7 64 bit step by step. For ORACLE 12c installation minimum 2GB swap required.
Download ORACLE 12c R1 software form www.oracle.com accept OTN License Agreement, it’s download in two parts and it’s a zip file.
Table of Contents
Start Oracle Installation
After downloading software unzip file using the following command.
# mkdir /u01
# unzip linuxamd64_12102_database_1of2 -d/u01
# unzip linuxamd64_12102_database_2of2 -d/u01
After unzip these zip files now you have a single folder name is “database” which is containing installation file.
Now edit Hosts file, it’s contain IP Address & Hostname of machine using following command. Set host name using below command.
Update hostname
#vi /etc/hostname
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
192.168.1.105 ol7.localdomain oracle
We have two methods of Oracle 12c Installation
- Automatic
- Manual
1. Automatic Setup
For automatic installation run the below command but before running the below command you must have to configure YUM Server.
# yum install oracle-rdbms-server-12cR1-preinstall -y
This command is set automatically all requirement settings.
2. Manual Setup
In this article we are going to follow Manual method of oracle 12 installation. Add bellow lines in “/etc/sysctl.conf” file using below command.
# vi /etc/sysctl.conf
fs.file-max = 6815744
kernel.sem = 250 32000 100 128
kernel.shmmni = 4096
kernel.shmall = 1073741824
kernel.shmmax = 4398046511104
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
net.ipv4.ip_local_port_range = 9000 65500
Save changes using press Esc then Shift+: then wq then hit Enter. After saving these changes, run the below command for applying changes.
# /sbin/sysctl -p
Add bellow line in ‘/etc/security/limits.conf’ using bellow command.
#vi /etc/security/limits.conf
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft stack 10240
oracle hard stack 32768
Install Required RPMs
Now install Linux packages which are required for ORACLE installation, following bellow command, here we are installing .rpm file using YUM server, for YUM server configuration please visit on my website and to through it. Maybe some packages are already installed.
yum install binutils -y
yum install compat-libstdc++-33 -y
yum install compat-libstdc++-33.i686 -y
yum install gcc -y
yum install gcc-c++ -y
yum install glibc -y
yum install glibc.i686 -y
yum install glibc-devel -y
yum install glibc-devel.i686 -y
yum install ksh -y
yum install libgcc -y
yum install libgcc.i686 -y
yum install libstdc++ -y
yum install libstdc++.i686 -y
yum install libstdc++-devel -y
yum install libstdc++-devel.i686 -y
yum install libaio -y
yum install libaio.i686 -y
yum install libaio-devel -y
yum install libaio-devel.i686 -y
yum install libXext -y
yum install libXext.i686 -y
yum install libXtst -y
yum install libXtst.i686 -y
yum install libX11 -y

yum install libXi -y
yum install libXi.i686 -y
yum install make -y
yum install sysstat -y
yum install unixODBC -y
yum install unixODBC-devel -y
yum install zlib-devel -y
yum install zlib-devel.i686 -y
Create Oracle user and Groups
Now create some groups and user, using following commands.
groupadd -g 54321 oinstall
groupadd -g 54322 dba
groupadd -g 54323 oper
useradd -u 54321 -g oinstall -G dba,oper oracle
Set the password for ORACLE user using following command.
passwd oracle
Set SELINUX = permissive using below command, and firewall must be disabled, using bellow command.
# vi /etc/selinux/config
SELINUX=permissive
--Disable firewall
# systemctl disable firewalld
Create some appropriate Directories where is ORACLE software will be install, and giving privileges, using bellow command.
mkdir -p /u01/app/oracle/product/12.1.0/dbhome_1
chown -R oracle:oinstall /u01
chmod -R 775 /u01
Update .bash_profile
Login as Oracle user and update .bash_profile as below.
#vi .bash_profile
# Oracle installation Settings
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_HOSTNAME=ol7.localdomain
export ORACLE_UNQNAME=cdb1
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/12.1.0/dbhome_1
export ORACLE_SID=cdb1
export PATH=/usr/sbin:$PATH
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
After saving this file start runInstaller using bellow command.
$ cd /u01/database
$ ./runInstaller
