- 2. Kellyn Pot’Vin • Westminster, Colorado • Oracle ACE, Sr. Technical Specialist at Enkitec • Multi-Platform DBA • Specialize in performance and management of large enterprise environments. • Board of directors for RMOUG, Director of Training Days 2013 and Database Track Committee for KSCOPE 2013 • Blog: DBAKevlar.com • Twitter: @DBAKevlar
- 3. Why We Monitor our Databases • Pro-active notification of issues before resulting in outages/impact to users. • Awareness of performance, resource usage and demands. • Data collection to investigate performance issues- current, recent and historical. • Capacity planning. • Automation of maintenance work.
- 4.

- 5. Presentation Agenda • EM Architecture • EM Incident Rules and the Incident Manager • Metric Extensions- The Why and the How. • Performance Pages • Top Activity • Diagnosing Issues • SQL Monitor • ASH Analytics
- 6. Simple EM Architecture • Oracle Repository stores data in an Oracle database. • OMS (Oracle Management Service) • Targets with OMA(Oracle Management Agent)/Plug- ins upload data to OMS. • Cloud Control Console, (aka EM Console) Used to view data through interaction with OMS.
- 7. Effective Monitoring with Incident Manager
- 8. Creating Incidents From Alerts
- 9. Incident Rules From EM12c Console •Setup •Incidents •Incident Rules/ Job Events
- 10. Incident Rule Sets • Two Non-Editable, Main Rule Sets Come with EM12c Installation, • Incident Management • Event Management
- 11. Incident Management Rules- Broken Down • Incident Creation for metric alerts • Auto- Clear rule for metric alert older then 7 days. • Auto-Clear rule for job status change for terminal status events. • SLA Incident Creation • Incident Creation for Target Unreachable, Down and Error. • Clear ADP, (Application Dependency and Performance) alerts without incident after 7 days. • Incident creation rule for high-availability events.
- 12. Utilizing Existing Rule Sets 1. Disable existing, Non-editable, system generated, incident management rule set. 2. Pre-existing are Quality Rule Sets, but need to be editable. 3. Need to Copy the Incident Rule Sets. 4. Enhance or Add Additional Rules to the New Copy of a Rule Set.
- 13. Disabling and Copying Rule Sets
- 14. Copying a Rule Set • Fill in new name of Incident Rule Set. • Defaults to all targets, exclude, change to target types or specific types. • Enable if copying a disabled rule set.
- 15. Copying Rule Set, Rules Tab • Click on the Rules Tab • You can Edit Existing rules, enhancing, updating or changing default settings. • Remove any unwanted rules. • Add specific rules for your environment.
- 16. Copying Rule Set, Co-authors
- 17. Rules vs. Metric Thresholds • Rule are Set Globally. • Rules are Independent of Database Metric Settings.
- 18. Metric Settings • Set at database level unless using a template. • In 12.0.1.0 BP1, only set with warning thresholds. • Good reason to use a template.
- 19. What Are Metric Extensions? • A dynamically configured extensions feature allowing to monitor environment specific conditions. • Simplifies monitoring of operational processes that once only existed outside of the EM12c console. • Eliminates requirements for secondary monitoring and management tools. • Eliminate need for external scripting that may require more monitoring logic than EM Jobs can provide.
- 20. Metric Extensions Details • Metric Extensions replace the formerly known “User Defined Metrics” • User Defined Metrics were limited to database and host types, no longer with Metric Extensions. • Ability to build a metric extensions library to utilize for your own environment. • Full development cycle support • Using specific protocols , the Oracle Integration Adapter gathers data about targets for use with metrics extensions.
- 21. The “More” of Metric Extensions • A simple wizard allows for easy development and refinement of metric extensions. • Ability to test metrics using the “Test Page” allows an ability to run real-time metric evaluations to ensure definitions and scripts are free of errors before deploying. • Loved, stand-alone scripts, with small changes can become metric extensions, too!
- 23. Enterprise > Monitoring > Metric Extensions
- 24. The Creation
- 26. Creation, Part III • Defaults meet the needs for example.
- 27. Creation, IV
- 28. Add Columns • Columns • AGENT_PID with Description of “AGENT PID” • MEM_USG with Description of “MEMORY USAGE” • VAL_MEM with Description of “VALUE of MEMORY” • Number of occurrences before alerting=5, then click OK
- 29. Credentials • Choose a pre-existing setup or new?
- 30. The Finale! • Test, rinse, and repeat, (deploy/publish!)
- 32. Metric Extensions Summary • Create development metric extension, wizard will simplify process. • Test with test page and verify that all steps, all features of the metric extension test correctly. • Deploy to target separately or to groups. • Utilize to fulfill any missing areas in monitoring environment.
- 33. EM12c Performance Pages • Summary Page • Top Activity • SQL Monitor • ASH Analytics • ASH/AWR Reports • SQL Tuning Advisor • Misc. Features
- 34. The Summary Page
- 35. Database Level Summary Page
- 36. Top Activity, “The Grid” • Graphical display of performance usage. • 15 second refresh, manual refresh or historical. • Review up to time retained in AWR.
- 37. The low down of the Top Activity • Top SQL on left. • Top sessions, clients, etc. on right in drop down.
- 38. Here’s our spike, which waits? • Commonly, focus on pink, orange, red and brown for issues. • Network and queuing do have opportunities for tuning, as well. • Green and blue are expected, but also part of problems when over utilized.
- 39. We’re in the Red, (Orange, too!) • Inspect High % use. • Red, orange, brown and pink.
- 40. Session Details
- 41. Next? • Two sessions are executing • Option to run an ASH report, (right hand side)
- 42. What ASH Tells Us
- 43. The Icing on the Cake • Duh, add some memory to the EM12c box!
- 44. SQL Monitor • Elapsed Time • SQL_ID, Beginning SQL Text. • Parallel, Waits and Execution Time
- 45. Top Activity, ASH style Ability to choose timelines by: Hour Day Week Month Calendar Custom
- 46. Familiar Interface Changes to interface were minimal for user comfort
- 47. Sql Details View
- 48. Load Map New Visual Way of Showing Data, Multiple Ways!
- 49. ASH Analytics Summary • Future of “Top Activity” • Easy Agent Deployment through EM12c Console • Comfortable Interface for those familiar with Previous Versions. • Cool new features, new learning curve for some. • Oracle user DOES NOT need sudo, disregard the instructions.
