Install Oracle Database 18C in silent mode on OEL7

This article presents how to install Oracle 18C on Oracle Enterprise Linux 7 (OEL7) in silent mode.

Read following article how to install Oracle Enterprise Linux 7: Install Oracle Linux 7 (OEL7) (for comfort set 8G memory for your virtual machine before proceeding with Oracle software installation).


Software for 12CR2 is available on OTN or edelivery

Database software

OS configuration and preparation

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

su - root

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

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

For example. oel7 localhost.localdomain localhost

Set hostname

hostnamectl set-hostname --static

Add groups

#groups for database management
groupadd -g 54321 oinstall
groupadd -g 54322 dba
groupadd -g 54323 oper
groupadd -g 54324 backupdba
groupadd -g 54325 dgdba
groupadd -g 54326 kmdba
groupadd -g 54327 asmdba
groupadd -g 54328 asmoper
groupadd -g 54329 asmadmin
groupadd -g 54330 racdba

Add user Oracle for database software

useradd -u 54321 -g oinstall \
-G dba,oper,backupdba,dgdba,kmdba,racdba oracle

Change password for user Oracle

passwd oracle


Check which packages are installed and which are missing

rpm -q --qf '%{NAME}-%{VERSION}-%{RELEASE}(%{ARCH})\n' bc \
binutils \
compat-libcap1 \
compat-libstdc++-33 \
elfutils-libelf \
elfutils-libelf-devel \
fontconfig-devel \
glibc \
glibc-devel \
ksh \
libaio \
libaio-devel \
libX11 \
libXau \
libXi \
libXtst \
libgcc \
librdmacm-devel \
libstdc++ \
libstdc++-devel \
libxcb \
make \
smartmontools \

If you have information that librdmacm-devel is not installed probably you can ignore it

[root@oel7 ~]# yum install librdmacm-devel
Loaded plugins: langpacks, ulninfo
Package librdmacm-devel-1.1.0-2.el7.x86_64 is obsoleted 
by rdma-core-devel-15-7.el7_5.x86_64 which is already installed

and extra packages if you want. I don’t install them

(for Oracle ACFS Remote)


(for Oracle ACFS)


(for Oracle RAC and Oracle Clusterware)


You can install missing packages from dvd. Just mount it and install missing packages using rpm -Uvh command from directory <mount dvd>/Packages or by using yum install command.

NOTE – I’m using x86_64 version of packages

First option from dvd

rpm -Uvh libaio-devel*.x86_64.rpm
rpm -Uvh ksh*.x86_64.rpm

Second option using yum install command. It requires access to internet.

yum install libaio-devel*.x86_64
yum install ksh*.x86_64

Add kernel parameters to /etc/sysctl.conf

# kernel parameters for 18C installation

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

Apply kernel parameters

/sbin/sysctl -p

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

# shell limits for users oracle 18C

oracle   soft   nofile   1024
oracle   hard   nofile   65536
oracle   soft   nproc    2047
oracle   hard   nproc    16384
oracle   soft   stack    10240
oracle   hard   stack    32768
oracle   soft   memlock  3145728
oracle   hard   memlock  3145728

Disable firewall

service iptables stop
chkconfig iptables off

Additional steps

Add following lines in .bash_profile for user oracle

# Oracle Settings
export TMP=/tmp

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


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

if [ $USER = "oracle" ]; then
    if [ $SHELL = "/bin/ksh" ]; then
       ulimit -u 16384 
       ulimit -n 65536
       ulimit -u 16384 -n 65536


Directory structure

Create directory structure as user root

ORACLE_BASE – /ora01/app/oracle

ORACLE_HOME – /ora01/app/oracle/product/

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

SSH server

I use it for later connection as user oracle in GNOME using command ssh -X. Without it it won’t be possible to run X interfaces like Oracle Universal Installer.

Install ssh server. It should be already installed.

yum install openssh-server

start ssh server

systemctl start sshd

verify it works

systemctl status sshd

Install database software

Let’s start with database software installation as oracle user. Usually I’m connected as user root in GNOME so you need to use ssh.

Connect as user oracle

[root@oel7 ~]# ssh -X

Let’s start with database software installation as oracle user. Copy zip to ORACLE_HOME directory and then uznip it. It’s ready binaries !

[oracle@oel7 ~]$ 
cp /ora01/app/oracle/product/
cd /ora01/app/oracle/product/

after unzip you should see following

[oracle@oel7 db_1]$ pwd
[oracle@oel7 db_1]$ ls
addnode cv drdaas javavm mgw ord precomp schagent.conf suptools
apex data dv jdbc network ordim QOpatch sdk ucp
assistants dbjava env.ora jdk nls ords R slax usm
bin dbs has jlib odbc oss racg sqldeveloper utl
clone deinstall hs ldap olap oui rdbms sqlj crs demo install lib OPatch owm relnotes 
sqlpatch wwg css diagnostics instantclient log opmn perl 
sqlplus xdk ctx dmu inventory md oracore plsql runInstaller srvm

check environment settings

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

[oracle@oel7 ~]$ alias envo tns cdoh cdob
alias envo='env | grep ORACLE'
alias tns='cd $ORACLE_HOME/network/admin'
alias cdoh='cd $ORACLE_HOME'
alias cdob='cd $ORACLE_BASE'

--run alias command envo to display environment settings
[oracle@oel7 ~]$ envo

--run alias command cdob and cdoh 
[oracle@oel7 ~]$ cdob
[oracle@oel7 oracle]$ pwd

[oracle@oel7 ~]$ cdoh
[oracle@oel7 db_1]$ pwd

Response files

Once Oracle 18C binaries are unzipped. In followinf directories you can find response files that stores parameters necessary to install Oracle components:

directory reponse file
$ORACLE_HOME/install/response db_install.rsp
$ORACLE_HOME/assistants/dbca dbca.rsp
$ORACLE_HOME/assistants/netca netca.rsp
  • db_install.rsp – used to install oracle binaries, install/upgrade a database in silent mode
  • dbca.rsp – used to install/configure/delete a database in silent mode
  • netca.rsp – used to configure simple network for oracle database in silent mode
[oracle@oel7 response]$ cd $ORACLE_HOME/install/response

[oracle@oel7 response]$ pwd

[oracle@oel7 response]$ ls *.rsp
[oracle@oel7 dbca]$ cd $ORACLE_HOME/assistants/dbca

[oracle@oel7 dbca]$ pwd

[oracle@oel7 dbca]$ ls *.rsp
[oracle@oel7 dbca]$ cd $ORACLE_HOME/assistants/netca

[oracle@oel7 netca]$ pwd

[oracle@oel7 netca]$ ls *.rsp

Install Oracle binaries

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

[oracle@oel7 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 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

-- specify extra groups for database management

once edition is completed. Start binaries installation.

cd /ora01/app/oracle/product/
./runInstaller -silent \
-responseFile /ora01/app/oracle/product/

output is following

[oracle@oel7 db_1]$ ./runInstaller -silent -responseFile 
Launching Oracle Database Setup Wizard...

Moved the install session logs to:

I got warnings about memory Oracle requires 8GB ram but VirtualBox consumed 128MB for VideoMemory.

you are asked to run two scripts as user root. Once it’s done binaries are installed. I’m not sure if it’s necessary from previous logs it looks it’s already done

[root@oel7 /]# 

quick binary verification

Configure Oracle Net

Again based on response file Oracle Net will be configured

cd /ora01/app/oracle/product/
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 /ora01/app/oracle/product/
[oracle@oel7 netca]$ netca -silent -responseFile 

Parsing command line arguments:
    Parameter "silent" = true
    Parameter "responsefile" =

Configure database

The last setup is to create new container database with one pluggable database PORA18C1 and configure and enable oracle db express

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 /ora01/app/oracle/product/

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

set own parameters

-- global database name

-- instance database name

--create container database

-- number of pluggable databases

-- list of pluggable databases

-- pluggable administrator password

-- template name used to create database

-- password for user sys

-- password for user system

-- configure dbexpress with port 5500

-- password for dbsnmp user

-- default directory for oracle database datafiles

-- default directory for flashback data

-- storage used for database installation
-- FS - OS filesystem

-- 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

-- defines size of memory used by the database

run database installation

dbca -silent -createDatabase \
-responseFile /ora01/app/oracle/product/

4 thoughts on “Install Oracle Database 18C in silent mode on OEL7

  1. Hello ,
    Great turorial ! It helped me to install oracle18c/19c on oracle linux 8.0. I followed most of the steps, except the one with creating the response file and the ones regarding the ssh.
    I tried to install with a response file and i got this errors:
    1. Wrong path on dbca: line 135 . Fix : modify $ORACLE_HOME/bin/platform_common the path for $OH
    Then got this:
    2. [DBT-00006] The logging directory could not be created.
    Did a little digging and found that the installation was still using some of its one default path with /u01 instead of using the one that i’ve put with /ora01.
    After that i’ve modified the path for home to be the one which was expected to not have any issue and proceed with gui installer. It worked fine.
    If you install on Oracle linux 8.0 you need this: export CV_ASSUME_DISTID=RHEL7.6 , othewise the install will not work.
    Info from here :

  2. I forgot to ask why oracle18c/19c expects that $KIT_HOME_ORACLE=$ORACLE_HOME? In the past this was different and the installation was copying itself the binaries to the a different location , not it doesn’t. Also its giving you an error:
    {FATAL] [INS-35954] The installer has detected that the Oracle home location provided in the response file is not correct.

  3. I got below error while creating database as below. how to resolve this
