Mark Beyer, GartnerDecember 2006
Oracle customers are highly satisfied with its
Real Application Clusters and Automatic Storage
Management when pursuing scale-out strategies.

Business and Technology Status 2007
  • Global economy is more dependent on IT than ever
    before
  • Information management is THE major mission of
    the enterprise
  • Organizations are being pushed to ADAPT quickly
    to change
  • Economic, Technologic, Regulatory
  • At least two-thirds of all IT spending is just
    to sustain the business, not to change or
    transform the business.
  • - Gartner Group

10
Oracle Database11g Big Message
  • Increases business and IT agility and lowers
    overall costs!
  • Enables change to happen while maintaining
    stability!
  • Takes management and diagnostic automation to the
    next level!
  • Freeing key personal for higher value tasks!
  • Simplifies your information infrastructure!
  • Provides the least expensive, most scalable,
    secure and highly available information
    management and rapid application development
    environment!

11
Make Change Safe
  • Enabling Change While Maintaining Stability

12
Barriers to Change
  • Proactive testing of upgrades is time consuming,
    costly, and often not as effective as needed
  • Upgrades still risk disruption of production
    systems
  • Many upgrades still require significant downtime
  • Still have to endure potentially long period of
    instability as bugs are found and fixed
  • DBAs are asked to do too much to help, e.g.,
    diagnostic patches that require more downtime
  • Software vendors take too long to fix bugs

13
Database Replay
14
The Need for Database Replay
  • Businesses want to adopt new technology that adds
    value
  • Extensive testing and validation is expensive in
    time and cost
  • Despite expensive testing success rate low
  • Many issues go undetected
  • System availability and performance negatively
    impacted
  • Cause of low success rate
  • Current tools provide inadequate testing
  • Simulate synthetic workload instead of replaying
    actual production workload
  • Provide partial workflow coverage

Database Replay makes real-world testing possible
15
Database Replay
  • Replay actual production database workload in
    test environment
  • Identify, analyze and fix potential instabilities
    before making changes to production
  • Capture Workload in Production
  • Capture full production workload with real load,
    timing concurrency characteristics
  • Move the captured workload to test system
  • Replay Workload in Test
  • Make the desired changes in test system
  • Replay workload with full production
    characteristics
  • Honor commit ordering
  • Analyze Report
  • Errors
  • Data divergence
  • Performance divergence

21
Automate Still More Administrative Functions
  • Freeing key personal for higher value tasks!

22
Why Automate?
  • Free key personal for higher value tasks!
  • Increased DBA productivity
  • Reduce risk of DBA errors
  • Dramatically increase the QOS DBAs deliver
  • More proactive management and planning
  • Continual optimized performance
  • Higher availability

23
Long Term Project
  • Goal Automate all administrative functions
  • Over three releases
  • Begun in Oracle9i
  • Major focus in Oracle Database 10g
  • Continued major focus in Oracle Database 11g
  • Three step process

    identifies sub-optimal behaviors, alerts DBA to
    problems, and advises on corrective actions
  • Automation gives DBAs the option to turn on
    full automation

Simplify Systems
  • Simplify Your Information Infrastructure For
    Maximum Agility and Lowest Cost!

31
Old Pre-Grid Infrastructure
32
The Cost of Same Old Approach
  • Poor Resource Utilization
  • Built for peak periods
  • Gartner estimates average server utilization rate
    at 5-10!
  • Standby hardware and software costs virtually
    double the investment and further reduce useful
    utilization
  • Management happens in silos
  • Uneven process maturity across managed silos
  • Availability, security, performance
  • Increased staff
  • Proliferation of tools that have overlapping
    capabilities
  • Software patching/testing, upgrade tasks are
    multiplied
  • Increases information complexity and lowers
    agility
  • More data movement required (i.e. increased
    latency, increased storage, increased integrity
    issues)
