Install Oracle Database 19C in silent mode on OEL7

This article presents how to install Oracle 19C 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 19C 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

Set hostname

hostnamectl set-hostname --static

It’s recoomended to update OS with latest packages

yum update

Extra configuration steps:

  • add new OS groups
  • add new OS user
  • install required OS packages
  • set specific kernel parameters
  • disable transparent hugepages and defrag

Above steps can be done automatic or manually


Execute following command

yum install -y oracle-database-preinstall-19c

Details about steps executed by above statement can be found in file



Manual installation can give you more control on installation

Add groups

#basic groups for database management
groupadd -g 54321 oinstall
groupadd -g 54322 dba
groupadd -g 54323 oper

#extra dedicated groups can be ignored for simple installations 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

Install required packages

Add kernel parameters to /etc/sysctl.conf

# kernel parameters for 19C 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.conf.all.rp_filter = 2
net.ipv4.conf.default.rp_filter = 2
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 19C

oracle   soft   nofile   1024
oracle   hard   nofile   65536
oracle   soft   nproc    16384
oracle   hard   nproc    16384
oracle   soft   stack    10240
oracle   hard   stack    32768
oracle   soft   memlock  134217728
oracle   hard   memlock  134217728

Disabling Transparent Hugepages and defrag

This step is recommended by Oracle to avoid later performance problems – Doc ID 1557478.1. It can be done by adding transparent_hugepage=never to /etc/default/grub

[root@oel7 ~]# cat /etc/default/grub
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_CMDLINE_LINUX="crashkernel=auto rhgb quiet numa=off transparent_hugepage=never"

After applying and rebooting host can be checked with following command

[root@oel7 ~]# cat /sys/kernel/mm/transparent_hugepage/enabled
always madvise [never]

Next steps

Create directory structure for binaries 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

Disable firewall

systemctl stop firewalld
systemctl disable firewalld

Add following lines in /home/oracle/.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


Install database software

Connect as user oracle

[root@oel7 ~]# su - oracle

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/ unzip

after unzip you should see following

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

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 --to check ORACLE_BASE, ORACLE_HOME [oracle@oel7 ~]$ cdob [oracle@oel7 oracle]$ pwd /ora01/app/oracle [oracle@oel7 ~]$ cdoh [oracle@oel7 db_1]$ pwd /ora01/app/oracle/product/

Response files

Once Oracle 19C binaries are unzipped. In following directories you can find response files that stores parameters necessary to install Oracle components:

directory response 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 /ora01/app/oracle/product/
Launching Oracle Database Setup Wizard...

The response file for this session can be found at:

You can find the log of this install session at:

As a root user, execute the following script(s):
1. /ora01/app/oraInventory/
2. /ora01/app/oracle/product/

Execute /ora01/app/oraInventory/ on the following nodes:
Execute /ora01/app/oracle/product/ on the following nodes:

Successfully Setup Software.
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/
netca -silent -responseFile /ora01/app/oracle/product/

Parameter "silent" = true
Parameter "responsefile" = /ora01/app/oracle/product/

Configure database

The last setup is to create new container database with one pluggable database PORA1891 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

-- Flag to create local undo tablespace for all PDB's.
