How to install Oracle 12.1 in silent mode

Credit: I have used some Tim Hall installation notes for this.

I have installed Oracle on Oracle Linux 6.3 64 bits with the Oracle validated RPM for 11.2 (this will install all packages needed by Oracle, configure Linux kernel, create ‘oracle’ account and change other setttings required for Oracle Database software installation):

# yum install oracle-rdbms-server-11gR2-preinstall -y

Start by disabling firewall and SELINUX and then reboot:

# service iptables stop
# chkconfig iptables off
# grep SELINUX /etc/selinux/config
#SELINUX= can take one of these three values:
# SELINUXTYPE= can take one of these two values:
# reboot

Create the Oracle Home directory:

# mkdir -p /u01/app/oracle/product/12.1.0/db_1
# chown -R oracle:oinstall /u01
# chmod -R 775 /u01

Create additional group and assign it to ‘oracle’ account:

# groupadd -g 54323 oper
# usermod -u 54231 -g oinstall -G dba,oper oracle

Switch to ‘oracle’ account and unzip Oracle media in /tmp:

$ unzip
$ unzip

Install Oracle software with following script:

cd /tmp/database
export DISTRIB=`pwd`
./runInstaller -silent \
-responseFile $DISTRIB/response/db_install.rsp \
oracle.install.option=INSTALL_DB_SWONLY \
UNIX_GROUP_NAME=oinstall \
INVENTORY_LOCATION=/u01/app/oraInventory \
ORACLE_HOME=/u01/app/oracle/product/12.1.0/db_1 \
ORACLE_BASE=/u01/app/oracle \
oracle.install.db.InstallEdition=EE \
oracle.install.db.isCustomInstall=false \
oracle.install.db.DBA_GROUP=dba \
oracle.install.db.OPER_GROUP=dba \
oracle.install.db.BACKUPDBA_GROUP=dba \
oracle.install.db.DGDBA_GROUP=dba \
oracle.install.db.KMDBA_GROUP=dba \

This has started installation in the background: you need to wait until something similar to the following is displayed:

The installation of Oracle Database 12c was successful.
Please check '/u01/app/oraInventory/logs/silentInstallXXX.log' for more details.

As a root user, execute the following script(s):
1. /u01/app/oraInventory/
2. /u01/app/oracle/product/12.1.0/db_1/

Successfully Setup Software.

As requested run following scripts with ‘root’ account:

# /u01/app/oraInventory/
# /u01/app/oracle/product/12.1.0/db_1/

Modify oracle user .bash_profile to add:

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

export ORACLE_HOSTNAME=hostname.localdomain
export ORACLE_UNQNAME=cdb12c
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/12.1.0/db_1
export ORACLE_SID=cdb12c

export PATH=/usr/sbin:$PATH

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

Logout and login again as ‘oracle’ and test:

$ sqlplus -v

SQL*Plus: Release Production
