  11. 11. Alfredo Krieg • Oracle ACE • Senior Cloud Performance Architect at Viscosity North America • Database Performance Tuning, Exadata, OEM and EBS • Oracle Technologies since 2004 • Blog • @alfredokrieg
  12. 12. Disclaimer • The opinions expressed in this presentation are solely mine, and not that of my employer.
  13. 13. Agenda • Oracle Enterprise Manager – Architecture – Plug-ins – Discover and Setup – Performance Metrics – Systems Infrastructure Plug-in • Exadata – SMART IO – Flash Cache Resource Monitoring – Cellcli • Oracle Database – AWR Exadata Related Metrics – SQL Monitoring
  14. 14. OEM 13c Architecture • Oracle Management Repository • Oracle Management Service • Oracle Management Agent • Plug-ins • Java Virtual Machine Diagnostics • Cloud Control Console
  15. 15. OEM 13c Plug-ins • Default Plug-ins installed with OEM 13.3 – Oracle Database – Oracle Fusion Middleware – Oracle Exadata – Oracle Cloud Framework – Oracle System Infrastructure • The plug-in must be deployed on the OMS first then the OMA • OMS plug-in can be a higher version – Compatibility issues – Errors – Metric Collection Errors
  16. 16. Exadata Plug-in • OEM 13.3 – Exadata Plug-in – Exadata Virtualization Provisioning • Create/delete RAC cluster (VMs, DB, GI, ASM) • Scale up/down a RAC cluster – Monitor Exadata Flash Cache Features – Enhanced Exadata Hardware Management – Patching Automation Support • Compute Nodes (Firmware and OS) • Exadata Storage Cell Servers (Firmware and OS) • Infiniband Network (Firmware) • Quarterly Full Stack Patches – Database – Infrastructure (Storage Cell Server, Infiniband, PDU) – ORAchk/EXAchk Integration – Auto Service Request (ASR) Integration: Faulty Telemetry
  17. 17. Exadata Plug-in • Deployment Pre-reqs 332AEFBEF976.htm#EMXIG215
  18. 18. Exdata Discovery • Deploy OMA on compute nodes • Run Discovery Precheck Script – From the OEM agent directory – Doc ID 1473912.1 – Credentials needed cellmonitor SSH, oemuser ILOM , nm2user Infiniband • From OEM Console -> Setup -> Add Target -> Add Targets Manually
  19. 19. Exadata Discovery • Add Using Guided Process -> Oracle Exadata Database Machine
  20. 20. Exadata Discovery • 13c or 12c?
  21. 21. Exadata Discovery • 13c target type – Enhanced Monitoring – Allows Plug-in to monitor Exadata Storage Server and KVM – Enterprise Manager Systems Infrastructure Plug-in the rest of hardware targets in the rack • 12c target type – Exadata Plug-in only monitors all the components • If you already have an Exadata discovered with 12c target type? – You can upgrade the target types from the Exadata Home Page
  22. 22. Exadata Discovery • Select the OMA deployed in the first compute node • Rest of discovery steps 368960BA2482.htm#EMXIG139
  23. 23. Exadata Topology • DB Machine Schematic and Photo-Realistic
  24. 24. Exadata Resource Utilization • Navigate to Database Machine -> Resource Utilization -> Compute Resources
  25. 25. Performance Metrics Storage Cell Server • Storage Cell Server
  26. 26. Performance Metrics Storage Cell Server • Storage Cell Server
  27. 27. Performance Metrics Storage Cell Server • Storage Cell Server Metrics – 100+ Metrics available in 15 categories • Celldisk Statistics • Cell Offload Efficiency • Cell Statistics • Cell Summary • Consumer Group • Critical Event • Database Resource Manager • Database Statistics • Filesystem Utilization • Flashcache Statistics • Griddisk Statistics • Interconnect • LUN Statistics • Physicaldisk Statistics • Response Category – Option to create Metric Extensions
  28. 28. Enterprise Manager Systems Infrastructure • Enterprise Manager System Infrastructure Plug-in (13c only) – Compute Node Schematic – Photo-Realistic Topology C771BB76728D.htm#EMSIM131
  29. 29. Enterprise Manager Systems Infrastructure • Targets monitored – Servers – Storage servers – Networks – Racks and power distribution units (PDUs) – Oracle Solaris and Linux operating systems – Oracle Solaris Zones – Oracle VM Server for SPARC and logical domains – Oracle SuperCluster engineered systems 81
  30. 30. SMART IO – Cell Server • Ability to OFFLOAD processing to the storage servers
  31. 31. SMART IO – Cell Server • SQL operations that benefit from SMART IO – Smart Scans Predicate Filtering • Only the rows requested are returned – Smart Scan Column Filtering • Only the columns requested are returned – Smart Scan Join Processing • Joins are processed in the storage layer. Implemented using Bloom Filters – Smart Scan Processing of Encrypted Tablespaces and Columns – Storage Indexing • Exadata examines Storage Index before any I/O is done – Offload of Data Mining Model Scoring • All data mining functions are offloaded – Other • Database backups and Tablespace creation
  32. 32. SMART IO – Flash Cache • Flash for Database Objects – Automated caching mechanism for frequently-accessed data – DB and Storage Servers communicate and have the visibility of objects need to be cached – Understand the nature of all I/O operations – Objects larger than the size of the flash cache – only a portion is cached – Exadata Smart Flash Cache Compression • Flash for Database Logging – Redo logs are multiplexed between disk and flash cache – Exadata will do parallel write to both and when either of these competes database will be notified – Not a permanent store for redo data – just temp to provide fast redo write response time
  33. 33. Flash Cache Resource Monitoring • I/O Utilization (as percentage) • Hard Drive I/O Time Breakdown (in milliseconds per request) • Flash I/O Time Breakdown (in milliseconds per request)
