  • 1. Managing Exadata with OracleEnterprise Manager 12c Presented by: Andy Colvin February 12, 2013
  • 2. About Enkitec—  Oracle-Centric Consulting Firm —  US —  UK—  Extensive Exadata Practice —  Education —  Migration —  Performance Review —  On Call Support
  • 3. About Me —  Working around Oracle since 1999 —  Background in systems, network, database —  6 years at Enkitec —  Working on Exadata for 3 years —  Oracle ACE
  • 4. “Old School” - Exadata and OEM 11g —  Enhanced database management —  OEM 11g introduced Exadata plugins —  Separate plugins for each target type —  Storage Server —  ILOM —  KVM —  Infiniband Switch —  Cisco Switch —  Power Distribution Unit
  • 5. Installing Exadata Plugins – OEM 11g—  Death by 1,000 clicks—  Manual Deployment —  Deploy each plugin individually —  Create each target individually —  Manually configure SSH keys —  Manually configure SNMP alerts —  Create non-privileged user on ILOMs *not a true diagram for 11g
  • 6. OEM 11g Exadata Plugins—  Static Graphs —  24 Hours —  7 Days —  31 Days—  Few Metrics
  • 7. OEM 11g Exadata Plugins—  Lots of Text—  Realm Performance?—  Cell Performance?
  • 8. Enter OEM 12c!—  What can we do?—  OEM 12cR2 released October 2012—  Major upgrade from 11g
  • 9. OEM 12c Release 2 (12.1.0.2)—  Released recently—  Handles “Split Racks” much better—  Faster than Release 1
  • 10. Installing OEM 12c—  2 ways to get the software —  Download from OTN —  Requires separate database download —  Includes weblogic, OMS, and agent software —  OEM Setup Automation Kit for Exadata (MOS Note #1440951.1) —  Includes everything you need to install OEM (database, weblogic, OMS, agents)—  Install on single host, or separate database and management servers
  • 11. OEM 12c Architecture Changes—  OMS is central source of truth—  Agents are minimal installation —  Deploying from OEM console actually works!—  Everything is a plugin – only deploy what you need —  Database —  Exadata —  Oracle VM —  Exalogic —  Big Data Appliance
  • 12. OEM 12c Self-Update Console—  Download agents and plugins from OEM console—  Apply to OMS/agents
  • 13. Benefits of OEM 12c—  Pictures!—  Easy to configure—  Exadata as a target
  • 14. Exadata Plugin for OEM 12c—  Simple installation —  10 step discovery—  Single plugin —  Updated via self-update console
  • 15. Installing Exadata Plugin—  Add targets via guided process
  • 16. Installing Exadata Plugin—  Discover a new Exadata Database Machine
  • 17. Installing Exadata Plugin—  Choose one of the hosts —  Generally db01
  • 18. Installing Exadata Plugin—  Select an ORACLE_HOME—  Enter hostname for an Infiniband switch —  nm2user password is changeme
  • 19. Installing Exadata Plugin
  • 20. Installing Exadata Plugin
  • 21. Installing Exadata Plugin—  Enter agent username/password
  • 22. Installing Exadata Plugin
  • 23. Installing Exadata Plugin
  • 24. Installing Exadata Plugin
  • 25. Installing Exadata Plugin
  • 26. Benefits of OEM 12c —  Better graphs —  Customizable home pages per user —  Drag & drop interface for page customization
  • 27. Performance Graphs—  Text reports become graphs!
  • 28. Database Utilization—  Easily see resource consumption—  Dynamic graphs
  • 29. Compute Node Memory Allocation —  See memory allocation across compute nodes in the cluster
  • 30. Storage I/O Allocation —  See I/O utilization across storage servers in the cluster
  • 31. Infiniband Switch Metrics—  View switch health—  Healthy and degraded ports are color-coded
  • 32. Exadata Healthchecks Plugin—  Reads exachk results and creates OEM incidents—  Schedule exachk via cron or run manually
  • 33. Exadata Healthchecks Plugin—  Click to get incident details
  • 34. Active Session History Analytics—  Allows DBAs to drill down into performance pages—  Dynamically changing views based on user- defined filters—  Requires installation in each database—  Hard to find at first – look at the instance target, not the “cluster database” target
  • 35. Active Session History Analytics —  Displaying all wait events
  • 36. Active Session History Analytics —  Filtered by User I/O
  • 37. Active Session History Analytics —  Filtered by “Cell Single Block Physical Read”
  • 38. Chargeback—  Many Exadata environments are consolidation—  Allows for better reporting based on actual resources consumed—  *Requires Cloud Management Pack for Oracle Database or Fusion Middleware
  • 39. Configuring Chargeback—  Deploy the chargeback plugin to OMS—  Define a charge plan—  Add targets to charge plans—  Assign cost centers to targets—  Profit!!!
  • 40. Configuring Charge Plans—  Define a universal charge plan —  CPU —  Memory —  Storage
  • 41. Configuring Charge Plans—  Configure extended charges —  Database Options —  Number of RAC nodes —  Database version —  Network I/O
  • 42. Configuring Chargeback Targets—  Select a target, assign your charge plan —  Multiple types of targets can share cost plans
  • 43. Configuring Cost Centers—  Cost centers decide where charges are assigned to —  Different customers in DBaaS environments —  Different departments in enterprise consolidation environments
  • 44. Chargeback Reporting—  Reports can be delivered monthly —  Uses BI Publisher to send reports in PDF or HTML format —  View by resource, cost center, target type
  • 45. OEM Dashboards
  • 46. High Availability Console
