Oracle 12c Silent Installation on Oracle Linux 7

In this article we will be looking at Oracle 12cR2 silent installation on Oracle Linux 7.7. The steps are same for any version of Oracle Linux.

Note: read Oracle 12cR2 installation on Oracle Linux 7 in case you would like to install using GUI method

Software Requirements

We are going to setup OEL 7.7 virtual machine and install Oracle 12cR2 via silent method

  • Oracle Enterprise Linux 7.7

  • Oracle Database 12cR2

Install Oracle Linux 7

For this demonstration purpose, I have used virtualbox VM with 4 GB RAM and 120 GB hard disk. I have setup the virtual machine with exact same steps described in the following article

Install Oracle Linux on VirtualBox (OEL 7.7)

Oracle Prerequisites

Use the YUM repository to perform all the pre-install steps. Make sure your VM is able to ping google.com before executing below command

yum install -y oracle-database-server-12cR2-preinstall

Set password for the oracle user

passwd oracle

Create directories which will hold Oracle software installation

mkdir /u01
chown -R oracle:oinstall /u01
chmod -R 775 /u01

Copy the 12cR2 software files under /u01 and unzip it

su - oracle

cd /u01
unzip linuxx64_12201_database.zip

At this stage, you have two options to install Oracle software:

  • GUI Mode &

  • Silent Mode

I will be walking you through silent mode installation of Oracle software. As mentioned earlier, to install Oracle in GUI mode, refer to Oracle 12cR2 GUI mode install on Linux 7.

Oracle 12cR2 silent installation

Copy the 12cR2 software files to OEL 7.7 machine and create response file under /tmp location

vi /tmp/12cR2_response.rsp

Do not forget to replace ORACLE_HOSTNAME, ORACLE_HOME and ORACLE_BASE location in the below file


Go to 12cR2 installation software location and fire the runInstaller in silent mode

cd /u01/database

./runInstaller -ignoreSysPrereqs -showProgress -silent -responseFile /tmp/12cR2_response.rsp

Post installation, execute the root scripts as root user and installation will be completed.

Update bash_profile

At this stage, its a good idea to update Oracle user bash_profile to reflect ORACLE_HOME. Make sure you are at the Oracle user home location

as oracle user

cd             --> this command will take you to oracle user home location

Open .bash_profile

vi .bash_profile

Delete everything and put below contents. Make sure to change ORACLE_HOME location as per your installation

# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
	. ~/.bashrc

# User specific environment and startup programs
export ORACLE_HOME=/u01/app/oracle/product/
export ORACLE_SID=testdb


export PATH

Notice I have already put the ORACLE_SID variable. You must change it to the name of the database that you are going to create further.
