This document discusses how Oracle Enterprise Manager 12c provides improved management of Exadata compared to the 11g version. It summarizes the key enhancements in 12c including easier installation of plugins, dynamic performance graphs, health check monitoring, chargeback reporting, and dashboard customization. The installation process is simplified to deploying a single Exadata plugin which discovers the entire cluster. Administrators can now easily view metrics on database utilization, storage I/O allocation, and Infiniband switch health.

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

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
