  • 25. Disaster  Recovery  •  Focussed  Overview  of  Recent  Experience  •  Predominantly  with  JD  Edwards  in  mind   –  Purpose   •  Lessons  learned  from  the  field   •  What  works  best  /  What  doesn’t?     •  What  fits  your  business  expectaEons  for:   –  Return  to  OperaEon  (RTO)  ?   –  How  long  can  the  business  survive  without  this  core  system   •  Is  distance  a  factor?   The most comprehensive Oracle applications & technology content under one roof
  • 26. Business  ConsideraEons  •  Human  Resource  Issues   –  Staff  dealing  with  personal  &  family  issues   –  Key  staff  oeen  have  to  step  up  beyond  the  call!  •  Site  Access   –  Days  to  get  an  engineer  to  give  the  OK  to  site  access   –  Building  irreparably  damaged   –  Servers  &  server  room  destroyed   –  Physical  constraints  –  i.e  Roading   –  And  Many  More!!!   The most comprehensive Oracle applications & technology content under one roof

Provoking  Thought  •  What  is  in  place  today  if  a  disaster  occurred  •  Do  you  have  a  true  DR  strategy  or  HA  only?  •  Could  you  be  confident  that  your  business  would   conEnue  to  operate  in  the  event  of  a  disaster?  •  Can  you  put  a  cost  to  each  hour  of  outage  for   your  business?  •  Can  you  keep  doing  business  with  system  users  in   other  ciEes?  •  Does  your  business  need  up  to  the  Nano-­‐second   data  or  point  in  Eme?   The most comprehensive Oracle applications & technology content under one roof
  • 28. Typical  Infrastructure                Produc6on                Test  /  DR   The most comprehensive Oracle applications & technology content under one roof
  • 29. Scenario  One    •  Earthquake  –  city  wide  impact  –  huge   destrucEon  –  server  room  within  the  cordon  –   liquefacEon  in  the  server  room  –  building   structurally  unsound.    •  Decision  made  early  to  switch  to  DR  soluEon   in  another  city.    •  But!!!   The most comprehensive Oracle applications & technology content under one roof
  • 30. Scenario  One  -­‐  LiquefacEon     The most comprehensive Oracle applications & technology content under one roof
  • 31. Scenario  Two    •  Earthquake  –  city  wide  impact  –  huge  destrucEon   –  server  room  within  the  cordon  –  no  power  to   server  room  –  limited  access.    •  DR  site  was  in  the  midst  of  change  –  switching  to   DR  might  be  painful.  •  Generator  onsite  within  24  hours    •  Decision  made  to  stay  with  the  producEon   system  located  on  the  customer  site.    •  But!!!   The most comprehensive Oracle applications & technology content under one roof
  • 32. Scenario  Two  –  No  Electricity     Do  you  have  access  to  one  of  these?   The most comprehensive Oracle applications & technology content under one roof
  • 33. Scenario  Three    •  Earthquake  –  city  wide  impact  –  huge   destrucEon  –  server  room  within  purpose   built  data  centre  –  limited  outage.    •  Cross  city  DR  site  did  not  need  to  be  invoked  •  Within  an  hour  all  other  sites  were  working  as   normal.    •  Local  staff  could  focus  on  family  and  conEnue   to  access  systems  remotely  as  infrastructure   allowed   The most comprehensive Oracle applications & technology content under one roof
  • 34. Lessons  Learned    •  Do  you  have  split  ProducEon  &  Test  /  DR   infrastructures?   –  Test  /  DR  ensures  that  your  DR  is  ready  for  acEon!   •  Network  &  Infrastructure  are  constantly  used  (tested)  •  Do  you  have  a  DR  strategy?  –  GREAT!   –  Have  you  tested  it  recently?   –  Did  you  deploy  a  JDE  full  package?  •  A  ‘Purpose  Built’  data  centre  is  best  for   ProducEon  -­‐  Why?  •  Test  your  DR  strategy  regularly     The most comprehensive Oracle applications & technology content under one roof
  • 35. What  Worked  –  What  Didn’t?    •  Data  ReplicaEon  –  sorted  J  •  Server  images  or  backups  in  hand?   –  Where  is  the  last  full  backup  of  this  machine?   –  What  do  you  mean  you  backed  up  the  structures   ONLY!!!   –  Where  are  the  JDE  installaEon  CDs?  •  Don’t  neglect  your  deployment  server  •  Ensure  your  client  technologies  are  covered    •  Any  business  criEcal  3rd  party  systems?     The most comprehensive Oracle applications & technology content under one roof
  • 36. Is  Distance  a  Factor?    •  Absolutely  –  you  don’t  want  your  DR  too  close   –  RIGHT?  •  Too  far  apart  –  shipping  consideraEons     –  Comms  costs  consideraEons  for  ANZ    •  Too  close  and  both  instances  are  affected  •  20km+    =    Ideal  minimum  separaEon     The most comprehensive Oracle applications & technology content under one roof
  • 37. In  Summary    The  solu6on  that  I  have  seen  work  best  is  as  follows.    •  Split  ProducEon  and  Non  ProducEon  (Test/DR)  infrastructures  •  ProducEon  hosted  in  a  purpose  built  hosted  facility  where  security,   power  circuit  redundancy,  generators  and  diesel  fuel  stocks  are   available  to  ensure  24x7  security  and  electricity  supply.  •  Non  producEon  either  hosted  in  an  alternate  facility  or  on  site  at   the  customer’s  premises  20+  kms  from  the  producEon  data  centre.    •  100Mb  metropolitan  LAN  or  equivalent  available  to  service   communicaEons  requirements  between  the  two  sites  •  Test  the  soluEon  regularly  &  ensure  your  backups  are  appropriate     The most comprehensive Oracle applications & technology content under one roof
  • 38. Build  Your  DR  SoluEon     to  match  your     Business  ExpectaEons     No  CEO/CIO/CFO  affected  by  the  Christchurch  earthquakes  has  wanted  to  reduce  their  disaster   recovery  protecEon  aeer  recent  events.       Most  have  requested  a  full  DR  review   Many  have  implemented  stronger  soluEons.       The most comprehensive Oracle applications & technology content under one roof
