1. Oracle VM: Every cloud has a virtual liningChristina Varga & Willem PoppParks Victoria17/08/2010 The most comprehensive Oracle applications & technology content under one roof

2. Who are we?

3. What’s this Presentation about? Free tickets! Practice & Experience … maybe Day out of the Office … not really. Real reason is that Oracle VM actually works! What was our experience with implementing Oracle VM

4. PV “Business Systems” – before 42

5. PV “Business Systems” – after 73

7. 13 marine national parks

8. 11 marine sanctuaries

9. 3 wilderness parks

10. 27 state parks

11. 31 metropolitan parks

12. 63 other parks (including regional and reservoir parks)

13. 2,785 natural features reserves and conservation reserves

14. 8,400 Aboriginal Affairs Victoria registered Indigenous cultural heritage sites/places

15. 2,500 (non-Indigenous) historic places

16. 3.96 million hectares = 17% of Victoria

18. 21 Oracle Modules

19. 60+ other systems

20. GIS Team

21. Knowledge Management Team

23. Proposed Hardware 16 physical servers What were the original specs? Problems Problem 1: Space in Server room Problem 2: Air Conditioning in 30+ year old building Problem 3: Cost All the classic problems faced by growing IT dept with limited spaces

24. The BRIGHT Idea aka the “Cloud” that darkened our day “Virtualisation” One of the CIO’s bright ideas (blame IBRS analyst Kevin McIsaacs!) Problems, problems, problems… CRP on project already started No SAN storage available Six weeks to implement Due Dilligence “Feasibility Study” w. Cost/Benefit Analysis … ASAP!!!

25. VM Hardware Server pool comprising 4 physical servers 2 DELL PowerEdge servers 8CPU with 64GB RAM  one upgraded to 256GB 2 DELL PowerEdge servers 16CPU with 64GB RAM Storage DELL/EMC 10 x RAID 10 LUNs 3 x RAID 5 LUNs up to 8TB in total Databases 11g ASM DB VMs on one physical host 8CPU with 256 GB RAM

26. Hardware Schematic

27. Schematic details

28. VM Software OEL v4 – for Informatica OEL v5 – All other Oracle software is certified for this version

29. VM Benefits: The silver lining “Sales Pitch” Smaller Footprint Fewer physical servers Lower H/W licence cost Now properly licensed Lower Energy Use

30. VM Benefits: The silver lining ... beyond the Sales Pitch Time savings Built 33 servers in less than 1 month Scalability Applied the technology to different applications e.g. EBS, Oracle Data Warehouse (OBIEE), Informatica, Essbase, Oracle Spatial with few issues Ease of Management Same hardware to run VM with different O/S Efficient use of system resources by quickly migrating guests in busy times Networking changes during working hours by migrating guests to other hosts and schedule downtime on one host at a time. (e.g. undertook NIC reconfiguration during work hours with considerable cost saving on consultancy)

31. VM Implementation Timeline Prototype within 2 days from consultant walking in the door! Dev & Test environments on legacy box Full set up = 2 weeks on new H/W Dev, Test, Pre-Prod, Prod Includes training for key staff (of 1!) Longest delay was ordering hardware = 6 weeks

32. VM Implementation Issues SAN Connectivity Default DELL/EMC connectivity is PowerPath, but not certified with OEL Took 4 weeks to resolve because of Needed to multi-path Server RAM

33. KPIs What made it work… so well? Really, really good advice Expert advice from Oracle ACS Expert Technical DBA Real People (not just resources!) “Team Fit” Three key resources worked well as a “Black Box” unit Management who listened If you don’t know better, trust your staff. I didn’t (know better) so I did (trust my staff)!

34. VM Implementation Effort Over 1 month (ball park) Internal 1 x DBA = 1 month Management Support = 1 week Infrastructure 2 x Hardware Resources = 2 weeks Install storage, LUN, etc External Technical DBA = 2 weeks Consultant with Oracle ACS = 2 weeks Linux Consultants = 1 weeks

35. VM Ongoing Support Structure Internal 1 x DBA - 50% 1 x Technical Analyst - 10% 0.5 x Team Leader - 5% External Tech DBA 1 day/month Consultant with Oracle ACS if required

36. Future Plans Move our VM Ware across Client Server applications Legacy systems running SQL Server & Windows Application Express Migrate legacy data from 11i environments
