2 Years of Exadata in Production

  1. 1. Targetbase and Exadata:Looking Back at the Last 2 Years Presented by: Brad Peek & Andy Colvin August 14, 2012
  2. 2. About Enkitec Oracle-Centric Consulting Firm  US  UK Extensive Exadata Practice  Education  Migration  Performance Review  On Call Support
  3. 3. About Targetbase Direct Marketing Agency  Pharmaceutical  Automotive  Utilities  Consumer Goods Broad Range of Applications  Informatica  Unica  SAS  Business Objects
  4. 4. Targetbase 2+ Years Ago Previous Environment  10gR2 RAC  Single database Customer Base Growing  5% month-over-month growth  Needed to split customers  Direct access  Backup/Recovery
  5. 5. Enter Exadata! 2 quarter rack systems Production, DR Don’t change the code!
  6. 6. Migration To Exadata Clients moved to Exadata one at a time Up and running in 2 months
  7. 7. First Impressions Speed! Most applications ran faster  No code changes Stability was a concern early
  8. 8. Keeping the Ball Rolling Things work differently  Full scans are your friend  DW queries don’t need indexes  Can’t drop them for OLTP
  9. 9. OLTP vs Data Warehouse Mixed workloads can be tricky Alter session  set optimizer_index_cost_adj = 10000  Used in certain cases to avoid hinting SQL  Informatica source connections (not target) 3rd party applications where you can’t get to the SQL
  10. 10. Ongoing Support Heavy use of compression  OLTP compression  HCC compression Client databases shrink  Saves customers money  Allows more customers on the rack  1,027GB  635GB (29% reduction)  1,839GB  1,310GB (38% reduction)
  11. 11. Targetbase Today Twice the customers from 2010  Performance still holding steady Upgrading to half rack  Existing quarter racks become disaster recovery Implementing Resource Manager and IORM to avoid performance issues during extra busy times
