the oracle expert

where you will learn oracle technologies

and products

such as rack asm exadata oem

golden gate data guard etc and also unix

with hands-on experiments using oracle

virtualbox and start

your journey towards becoming an expert

oracle dba

in today's tutorial of this series we

are going to learn

how to create an oracle virtualbox

virtual machine

and install oracle linux operating

system

if you have a desire to build your

carrier as an oracle dba with unique

skills

or you are already an oracle dba then

it's really important

to keep yourself up to date with the

oracle technologies

and build your confidence with hands-on

experiments with it

this confidence will not only help you

achieve a brighter career

and get better job opportunities but

also it will help you solve real-world

problems

i am preparing this series of videos to

help you achieve your goal

where we will cover the following topics

oracle virtualbox virtual machine

concepts

oracle database 18c and 19c installation

dns or domain name system server

configuration

oracle enterprise manager or oem 13c

installation

oem target discovery promote and

grouping

oem incident rule sets and alert

configuration

oracle real application cluster physical

standby

snapshot standby and active data guard

golden gate replication both uni or

bi-directional configuring a virtual

exa-data environment

please note that each of these topics

may take one or more episodes

for the covers also i will go into only

that much depth

from where you can then take it forward

for the computer that will be hosting

the virtual machines

you may have windows linux or mac

operating system installed

in this demonstration i am using a

custom build server with windows 10

professional install

before we start please make sure that

your host computer has

at least 50 gigs of free space at least

16 gigs of ram or physical memory a

multi-core processor

with at least four logical processors

from where you can take

one or two processors for the virtual

machines

the virtualization option is enabled in

the host

in this demonstration i am using my

personal server

that i made with very high capacity

configuration

this is a windows 10 professional server

with

two eight core geon processors resulting

in 16 total cores

and with hyper trading enabled it has a

total of 32 logical processors 64 gigs

of physical memory

and at least one terabyte of free space

available on a bunch of solid state

drives

or ssds for better performance

i will explain how i made this home

server for all my gaming

oracle unix practice and media related

needs spending less than 1200 dollars

in a future video you can find how to

enable virtualization option

in your host computer's bios based on

the make and model of your motherboard

of your computer the virtualization

option can be found under advanced tab

if the virtualization option in your

bios is not set

then there is a possibility that going

forward you will encounter issues with

your virtual machines

to verify if your host is ready to

install virtualbox

and create virtual machines right click

on the taskbar

and go to the task manager

then go to the performance tab

click on the cpu where you will be able

to see how many logical processors are

there

in my server you'll be able to see there

are 32 logical processors

and the virtualization option is also

enabled

then go to memory it has around 46 gigs

of

memory in use and around gigs of memory

available making it a total of around 64

gigs

so i have enough capacity in my host

machine

to accommodate multiple virtual machines

so let's start with the oracle

virtualbox virtual machine installation

you can download it free from

virtualbox.org

once you are in the virtualbox.org

website click on the download virtualbox

6.1

which is the latest version of

virtualbox software

then based on your host operating system

select the option here in this

demonstration

i am using the windows hosts click on

that windows host

and it will take a few seconds to

download the installation program

the installation is quite

straightforward once you download the

installation program

just click on the downloaded program and

it will start the

virtual box software installation wizard

let it take all the default settings and

click next

click next again it will temporarily

disable the network interfaces

click yes

and click install

it will ask for confirmation to

install the device software from oracle

corporation

click install

and then click finish so once your

installation is done you will get an

interface like this

this is the oracle virtual box software

console

where we will create our virtual

machines

right now there is no machine and you

have a blank pen

at the left your virtualbox interface

will look a little different than mine

because i already have a bunch of

virtual machines created

and grouped under different titles here

so first we'll create one oracle linux

virtual

machine to do that we'll go to machine

new let's put the name of the new

virtual machine as

vm linux one

and you have to specify the machine

folder where

the virtualbox related files will be

copied

and you can choose the location from

here so i have selected

my d drive which i have created for all

my virtual machines the type will be

linux and the version

will be

oracle 64-bit

click next we'll allocate a memory of

4gb 4096

megabytes

click next we'll create a virtual hard

disk now

click create select the first option

that is the vdi virtualbox disk image

click next there are two options here

how the storage will be allocated to the

virtual disk

dynamically allocated and fixed size if

it is dynamically allocated

so it will be initially created with a

minimal size

and it will be extended as and when

required going forward

but that will compromise the performance

a little so

we will select our option as the fixed

size

and the location of the virtual disk

file will be

as specified earlier d colon virtual

machines

and i'm specifying one folder created

for this particular virtual machine that

is the vm linux one

and uh all the files related to this vm

linux one virtual machine will be

created under the folder

vm linux one then

we'll specify the size of the file as 50

gb

create it will take a couple of minutes

to create

the first disk file

so our first virtual machine is created

with the name vm linux1

and it is created under the group

exadata and

i'll simply drag it to the template

group

and it's under the template group now

now we have to define certain properties

of this virtual machine

before we start installing the operating

system

right now it's a blank virtual machine

without any operating systems installed

so when the virtual machine is selected

click on settings

go to advanced and

we will enable the bi-directional

clipboard and drag and drop

from the host to the virtual machine and

virtual machine to the host

and the snapshot folder it's already

taking the default location

it means whenever we are going to create

any snapshots for this particular

virtual machine that snapshot will be

saved in this

folder if you want you can specify a

different folder

description if you want any description

of this virtual machine you can

write it here this encryption will not

enable this encryption at this time

click on the system options

and it is taking the base memory as we

specified during the

beginning steps as 4gb

the boot order is taking as floppy

optical drive and hard disk

let it take that that way

and all the other options let it take

the default ones

under motherboards go to processor

we'll look at two processors here for

this

virtual machine

let the execution kept 100

and enable

pae nx check this option here

under acceleration let it take the

default options

go to display video memory will be 16 mb

monitor count will be one

and the graphic controller will specify

vbox vga do not enable the 3d

acceleration

and in the storage options it has only

one sata interface with one hard disk

that we created with the 50gb size

audio let it take the default options

then the network this is

a very important part here and

it can take up to four different network

interfaces

and for this virtual machine we will

take only one

the first one will enable network

adapter

and the type of the network adapter will

be bridged

adapter and let it take the name

by default as microsoft network adapter

multiplexer driver

click on the advanced options

adapter type it will take automatically

from the system the promiscuous mode

will be

allow all mac address let it take the

default one

cable connected should be on

and this is what the basic configuration

of the

network adapter all other network

adapters will be

in disable state because we need only

one for this virtual machine

usb let it take the default options

shared folder will define a shared

folder later on

and will keep all the other things as it

is

now click ok just ignore this

warning message below in valid settings

detected because this is basically

saying about the

type of the display that we have

selected here but

we'll stick to our this selection vbox

vga

now before we start first of all go to

preferences

under input select a virtual machine tab

and in the host key combination make

sure that you

select some keys which will help you to

switch between the host machine

and the virtual machine in this

demonstration i am using the left window

button

in my keyboard that is the host key

for me to be able to switch between the

host computer

and the virtual machine so if you want

to change it

simply click on that first clear

whatever is there

if you want to change it then press the

button that you want to be your host key

for example when i cleaned it now it is

none it means no keys have been assigned

now i press the left window button

and the left window button has been

selected as my host key

click ok and now we are going to

download oracle linux

from oracle corporation we will go to

oracle's

software download page which is

edelivery.oracle.com

i have given the link to this url in the

description of this video below

and to be able to download oracle

software you must have an account

created with oracle

you sign in with your account and then

in the search box we will put

oracle linux click search

it will give you a list of downloadable

oracle linux iso images

and from here we'll select the oracle

linux 7.9

and it will be added to your queue

then click continue

and in the next page select

the x8664 bit version of this oracle

linux 7.9

and click continue

you have to accept the terms of uses

click continue and it will ask for a

survey

you can simply submit your survey or you

can do it later on

in this space we'll get a lot of options

to install the oracle linux

7.9 we are mainly interested on the

first one

here that says oracle linux release 7

update 9

for x8664 with 4.5 gigs

we'll uncheck all the other boxes here

and select only the first one

click download

and it will download a small program

called

download manager we'll click that

and it will simply ask for the download

location by default it will be your

system's download folder

click next it will take a couple of

minutes to download 4.5 gigs of data

and your download is complete now to

install oracle linux on our virtual

machine we'll select the virtual machine

then go to settings

then go to storage and if you see

that this controller is the first one is

the optical this controller is empty and

here

we will select the downloaded iso image

of

oracle 7.9

this is the file that we downloaded the

first one

click open

and then click ok

and you can simply start

the virtual machine

so this screen is simply asking you to

map your optical device with the virtual

machine

so this is actually the f drive in my

system

so else it is by default selected i'll

simply

click start

the reason behind the error message just

we have seen

is because we mapped the optical drive

after

selecting the iso image so the iso image

was actually cleaned up from here

so all you need to do is to select it

again

now this is populated again

and then we will start installation of

the

oracle linux 7.9 in our partial machine

in this screen it will ask for

confirmation about installation of

oracle linux 7.9

and we will select the first option you

can navigate between the options using

the

up and down arrow buttons in your

keyboard so i selected the first option

install oracle linux 7.9 and press

enter

let's maximize the window

please note that we maximize only the

parent window

but the actual virtual machine window is

still a very small one and we'll fix

this by installing

virtualbox guest additions after our

installation is complete

i will select english united states

it is selected by default and one more

thing i would like to mention here is

when you click

inside this window you are actually

clicking on the virtual machine

so you will not be able to click outside

of this window once you are inside

in my machine the key that will help me

to go out of this virtual machine or

take control to the host machine is the

windows key in my keyboard

and if i click again inside of the

virtual machine then this mouse is

kind of imprisoned between this window

now we'll

simply click continue it will gather

some information and take a couple of

seconds

where we see some kind of exclamation

marks it means it's still working on

that

so installation source has been selected

software selection we have to select the

software options here

and the installation destination

we'll go to the installation destination

and we'll select

our 50 gb virtual hard disk that we

created

click again so that this check mark

comes there

then click done

under software selection will select

everything except the dns name server

and email server

let's go to the minimal installation tab

select everything infrastructure

accept dns and email

we'll select everything file and print

server

let's select everything basic web server

we don't need to install mariadb

let's select everything else

now the postgresql database client is

not needed

let's select the python and web servlet

engine

virtualization host select everything

under this we have already selected

everything and accept dns name server

and email server

click done the next thing we need to do

is to set a name for the host

let's put the host name as

vm linux 1

all in small letters

and enable the ethernet connection

and it has taken an ip addresses 192 168

157

click done

let it complete the remaining tasks of

checking the software dependencies

and installation source

now begin installation

and when the installation is in progress

we can set the root password here

see the root password will be the same

as the host name

just for simplicity and you can change

it later on

so the root password will be vm

linux 1 vm

linux 1. as we set

a very weak password here it's

complaining about

its complexity and just asking us to

confirm that we accept this weak

password

click done and done again

and at this time we will not create any

additional users

because we can anyway take care of that

later on and let the installation

proceed

after the first reboot it will ask for

accepting the license agreement

click on license information

scroll down to the end check that i

accept

check box and click done

then click on finish configuration

so english united states is selected by

default

you can switch off the location services

if you want i'm keeping it on

then the time zone it is selected as new

york

united states you can select your time

zone accordingly

click next

connect your online accounts you don't

have to do that now and you can skip

it

and here you have to specify your

username

full name and the username say i'm

putting my name here

and username will be the same

and click next password

click next and click on the start using

oracle linux server

and it will take a couple of seconds to

give you the initial screen

we'll simply close this first window

and here is your new virtual box virtual

machine

with linux 7.9 installed in the next

video of this series we will learn how

to install virtualbox guest additions

to extend its capabilities resize a

virtual disk
