5. What is VirtualBox?
§ Cross platform desktop virtualization software
§ Supported Hosts:
§ Window, Mac, Linux and Solaris
§ Runs on x86 based processors
§ Intel and AMD
§ Operating Systems Supported
§ Windows (32-bit/64-bit)
§ Linux (32-bit/64-bit)
§ Solaris (32-bit and 64-bit)
§ Benefit
§ Free!!!!!!

6. Requirements for VirtualBox
• Modern
computer
•
Preferably
with
Virtualiza8on
support
• Enabled
at
BIOS
• More
memory
the
be?er
• 4GB
min/8G
or
more
recommended
• Plenty
of
disk
space
• SSD
recommended

7. Virtualization Stack

8. Use Cases
• Applica8on
development
–
PL/SQL,
Java,
PHP,
APEX
• Test
disaster
recovery
scenarios
• RMAN
Backup
&
Recovery
• Data
Guard/GoldenGate
• Create
custom
appliances
• Database
server
• Applica8on
server
• Custom
apps
• Patch
tes8ng
• Run
Windows
on
a
Mac
-­‐
No
dual-­‐boot
required
• Dual
VPNs

9. Getting Started
Download
Install
Build
VMs
Timing:
10-­‐15
min.
See
download
page
for
templates
or
custom
build.

10. Learning Resources
• Oracle Learning Library
• Tutorials
• Demos
• Videos
• OTN Developer Days
• In-Person and Virtual
• Pre-Built Developer VMs

11. Oracle Learning Library

12. Pre-Built Virtual Machines
Loca8on
to
find
pre-­‐built
VMs

13. Pre-Built Virtual Machines
Big Data Lite Appliance

14. Moving VMs
• Export/Import
Formats
• Open
Virtualiza8on
Format
(OVF)
• Open
Virtualiza8on
Archive
(OVA)
–
add
disks
in
one
file
• Useful
for
handing
out
(OTNVDD)
• Benefits
• Useful
for
demos
and
hand-­‐outs
• Portability
between
different
hosts/OS
• Backups

15. Cloning VMs
• Clones
• Full
Clone
• Linked
Clone
• Benefits
• Quickly
create
VMs
• Linked
clones
save
space

16. Cloning VMs

19. Did you take a Snapshot?

20. Snapshots
• Point-­‐in-­‐8me
view
of
VM
• Convenient
method
of
tes8ng
changes
• Roll
back
and
forward
using
snapshots
• Use
snapshots
sparingly
• Consume
lots
of
space
• Snapshots
become
read-­‐only.
• New
data
wri?en
to
snapshot
deltas
• Do
not
use
as
backups!

21. Tips and Tricks
General
• Add physical memory
• Store virtual disks on SSD
• Install Guest Additions (changes every version)
• Enable memory over commitment (Page Fusion & Memory
Ballooning)*
• Disable Host I/O cache
• Use dynamic disks
• Linked Clones (reduce disk usage for multiple VMs)
• Snapshots

22. Networking Virtual Machines

23. Accessing Virtual Machines
• VirtualBox
GUI
– Remote
RDP
to
view
VM
from
different
machine
• Networking
– Connect
remotely
using
SSH,
VNC
etc.
• Port
Forwarding
– Connect
to
VM
from
host
using
forwarded
ports
• Shared
Folders
– Share
files
between
VMs
and
host

24. Accessing Virtual Machines
• Complicated/Confusing
• Network
Address
Transla8on
(NAT)
(Default)
• Port
Forwarding
• Host-­‐only
networking
• Bridged
Networking
• Internal
Networking
Tip:
Disable
firewalls
on
OS
within
VMs
Unix/Linux:
service
iptables
stop

25. Accessing Virtual Machines
NAT with Port Forwarding

26. Tips and Tricks
N etworking
• KISS principle
KEEP IT SIMPLE S______!

27. Command Line Interface
• Ran
by
VBoxManage
• Uses
Verb
that
do
the
same
in
GUI
• VBoxManage –help!
• VBOXManage list –l vm!
• VBOXManage clonevm
<vmname>!

28. Virtual Media Manager
• Quickly
see
what
disks
are
where
• Can
remove
as
needed
• If deleting VMs make sure
disks are remove from here

29. Shared Folders
• Easy
to
setup
• Quick
access
to
files
on
host
machine

30. Roll your own VM
• Download
sofware
from
OTN
• Oracle
Linux
at
E-­‐Delivery
• Install
as
needed
• OS of choice with patches
• Database software
• Applications

31. RAC Attack 12c
• Started by the IOUG RACSIG
• Held mostly at major conferences
• Collaborate, RMOUG, ECO, and
many others including
international
• SWAG
• Build a 2+n node RAC on your laptop
• Instructions (racattack.org/12c)
• Become a RAC Attack Ninja
