Agenda •  What is Oracle VM VirtualBox •  What do I need to run VirtualBox •  VirtualBox Virtualization Architecture •  Installing and Running VirtualBox •  VirtualBox Use Cases •  Learning Resources •  OTN Developer Days VirtualBox Appliances •  Accessing your VM Guests •  Tips and Tricks •  Snapshots

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!!!!!!

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  

Virtualization Stack

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  

Getting Started

Download  

Install  

Build  VMs  

Timing:  10-­‐15  min.  

See  download  page  for  templates  or  custom  build.  

Learning Resources •  Oracle Learning Library

•  Tutorials •  Demos •  Videos

•  OTN Developer Days •  In-Person and Virtual •  Pre-Built Developer VMs

Oracle Learning Library

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

Pre-Built Virtual Machines Big Data Lite Appliance

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

Cloning VMs •  Clones  

•  Full  Clone  •  Linked  Clone  

•  Benefits  •  Quickly  create  VMs  •  Linked  clones  save  space

Did you take a Snapshot?

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!  

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  

Networking Virtual Machines

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  

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  

Accessing Virtual Machines NAT with Port Forwarding

Tips and Tricks Networking •  KISS principle

KEEP IT SIMPLE S______!  

Command Line Interface

•  Ran  by  VBoxManage  •  Uses  Verb  that  do  the  same  in  GUI  

•  VBoxManage –help!•  VBOXManage list –l vm!•  VBOXManage clonevm

<vmname>!  

Virtual Media Manager

•  Quickly  see  what  disks  are  where  

 

•  Can  remove  as  needed  •  If deleting VMs make sure

disks are remove from here  

Shared Folders

•  Easy  to  setup    

•  Quick  access  to  files  on  host  machine  

 

Roll your own VM

•  Download  sofware  from  OTN  •  Oracle  Linux  at  E-­‐Delivery  

 

•  Install  as  needed  •  OS of choice with patches •  Database software •  Applications

 

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
