Install Oracle in silent mode 11G Release 2 (11.2) on OEL6

This article presents how to install Oracle 11G Release 2 in silent mode.

Silent mode installation allows to configure necessary Oracle components without using graphical interface nor any interaction with end user. It’s very useful method especially when you want to prepare standard installation using shell scripts.

Read following article how to install Oracle Enterprise Linux 6: Install Oracle Enterprise Linux 6 (for comfort set 4G memory for your virtual machine before proceeding with Oracle software installation).

Installation software is available on OTN version or metalink In this installation I’m presenting installation for but for previous version 11.2.0.X it shouldn’t be different.

Following components will be installed in silent mode:

  • oracle binaries: Oracle Enterprise Edition 11G Release 2
  • network components: listener LISTENER
  • database components: database and database console

OS configuration and preparation

OS configuration is executed as root. To login as root just execute following command in terminal.

su - root

Add groups

--groups for database management
--groups id are the same as for 12C installations
--some groups are not required here but can be used
--later for grid binaries installation

groupadd -g 54321 oinstall
groupadd -g 54322 dba
groupadd -g 54323 oper
groupadd -g 54327 asmdba
groupadd -g 54328 asmoper
groupadd -g 54329 asmadmin
Add user Oracle
--user id is the same as for 12c installations
useradd -u 54321 -g oinstall -G dba,oper,asmadmin oracle

Change password for user

passwd oracle
Add kernel parameters to /etc/sysctl.conf
kernel.shmmni = 4096 
kernel.shmmax = 4398046511104
kernel.shmall = 1073741824
kernel.sem = 250 32000 100 128

fs.aio-max-nr = 1048576
fs.file-max = 6815744
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

Apply kernel parameters

/sbin/sysctl -p

Add following lines to set shell limits for user oracle in file /etc/security/limits.conf

oracle   soft   nproc    131072
oracle   hard   nproc    131072
oracle   soft   nofile   131072
oracle   hard   nofile   131072
oracle   soft   core     unlimited
oracle   hard   core     unlimited
oracle   soft   memlock  50000000
oracle   hard   memlock  50000000

The /etc/hosts file must contain a fully qualified name for the server.

<IP-address>  <fully-qualified-machine-name>  <machine-name>

For example. oel6 localhost localhost.localdomain

Modify .bash_profile for user oracle in his home directory

# Oracle Settings
export TMP=/tmp

export ORACLE_BASE=/ora01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1


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

alias cdob='cd $ORACLE_BASE'
alias cdoh='cd $ORACLE_HOME'
alias tns='cd $ORACLE_HOME/network/admin'
alias envo='env | grep ORACLE'

umask 022

Check which packages are installed and which are missing

rpm -q --qf '%{NAME}-%{VERSION}-%{RELEASE}(%{ARCH})\n' binutils \
compat-libstdc++-33 \
elfutils-libelf \
elfutils-libelf-devel \
gcc \
gcc-c++ \
glibc \
glibc-common \
glibc-devel \
glibc-headers \
ksh \
libaio \
libaio-devel \
libgcc \
libstdc++ \
libstdc++-devel \
make \
sysstat \
unixODBC \

Install missing packages. It’s just example (many in one step):

yum install unixODBC unixODBC-devel sysstat

Stop and disable firewall

systemctl stop firewalld
systemctl disable firewalld

Create directory structure

ORACLE_BASE – /ora01/app/oracle

ORACLE_HOME – /ora01/app/oracle/product/11.2.0/db_1

mkdir -p /ora01/app/oracle/product/11.2.0/db_1
chown oracle:oinstall -R /ora01

Secure Linux

Disable secure linux by editing the /etc/selinux/config file, making sure the SELINUX flag is set as follows.


and enforce it

setenforce Permissive

Disable firewall

service iptables stop
chkconfig iptables off

Install database software

As Oracle user unzip software

su - oracle

cd /home/oracle

--unzip software

It should unzip it to one directory “database”

[oracle@oel6 ~]$ ls

Check directories and aliases for user oracle

--I defined 4 aliases in .bash_profile of user oracle to make 
--administration easier :)

[oracle@oel6 ~]$ alias envo cdob cdoh tns
alias envo='env | grep ORACLE'
alias cdob='cd $ORACLE_BASE'
alias cdoh='cd $ORACLE_HOME'
alias tns='cd $ORACLE_HOME/network/admin'

--run alias command envo to display environment settings

--run alias command cdob and cdoh to check ORACLE_BASE, ORACLE_HOME 
[oracle@oel6 ~]$ cdob
[oracle@oel6 oracle]$ pwd

[oracle@oel6 db_1]$ cdoh
[oracle@oel6 db_1]$ pwd

Response files

Once Oracle 11GR2 binaries are unzipped you can find in directory /home/oracle/database/response dedicated files called “response files” used for silent mode installations.

The response files store parameters necessary to install Oracle components:

  • db_install.rsp – used to install oracle binaries, install/upgrade a  database in silent mode
  • dbca.rsp – used to install/configure/delete a database in silent mode
  • netca.rsp – used to configure simple network for oracle database in silent mode
cd /home/oracle/database/response

[oracle@oel6 response]$ ls
dbca.rsp  db_install.rsp  netca.rsp

Install Oracle binaries

It’s the best to preserve original response file db_install.rsp before editing it

[oracle@oel6 response]$ cp db_install.rsp db_install.rsp.bck

Edit file db_install.rsp to set parameters required to install binaries. This is just example and in next releases parameters can be different. Each of presented parameter is very well described in db_install.rsp. I just give here brief explanations.

--force to install only database software

--set your hostname

--set unix group for oracle inventory

--set directory for oracle inventory

--set oracle home for binaries

--set oracle home for binaries

--set version of binaries to install
-- EE - enterprise edition

--force to install advanced options

--specify which advanced option to install
--  oracle.oraolap: - Oracle OLAP
-- - Oracle Data Mining
--  oracle.rdbms.dv: - Oracle Database Vault
--  oracle.rdbms.lbac: - Oracle Label Security
--  oracle.rdbms.partitioning: - Oracle Partitioning
--  oracle.rdbms.rat: - Oracle Real Application Testing
-- WATCHOUT - should be one line I have changed format here :)
--It's wrong

--specify extra groups for database management

once edition is completed. Start binaries installation

cd /home/oracle/database
./runInstaller -silent \
-responseFile /home/oracle/database/response/db_install.rsp

output is following

[oracle@oel6 database]$ ./runInstaller -silent 
-responseFile /home/oracle/database/response/db_install.rsp

Configure Oracle Net

Again based on response file Oracle Net will be configured

cd /home/oracle/database/response
cp netca.rsp netca.rsp.bck

You can edit netca.rsp to set own parameters. I didn’t changed anything here. So just start standard configuration. It will configure LISTENER with standard settings.

netca -silent -responseFile /home/oracle/database/response/netca.rsp

example output

netca -silent -responseFile /home/oracle/database/response/netca.rsp

Parsing command line arguments:
  Parameter "silent" = true
  Parameter "responsefile" = /home/oracle/database/response/netca.rsp

Configure database

The last setup is to create new database

Prepare directories for database datafiles and flash recovery area

mkdir /ora01/app/oracle/oradata
mkdir /ora01/app/oracle/flash_recovery_area

backup original response file for dbca

cd /home/oracle/database/response

cp dbca.rsp dbca.rsp.bck
vi dbca.rsp

set own parameters

--global database name

--instance database name
SID = "ORA11G"

--template name used to create database
TEMPLATENAME = "General_Purpose.dbc"

--password for user sys
SYSPASSWORD = "oracle"

--password for user system

--creates database console

--password for sysman user

--password for dbsnmp user

--storage used to create database
--FS - it means OS data files

--default directory for oracle database datafiles

--default directory for flashback dataa


--database character set

--national database character set

--listener name to register database to

--force to install sample schemas on the database

--specify database type
--has influence on some instance parameters

--force to use autmatic mamory management

--defines size of memory used by the database

run database installation

dbca -silent -responseFile /home/oracle/database/response/dbca.rsp
