Faced with insane expectations and a colossal amount of performance data, the Oracle DBA has an ominous challenge - especially when engaged in a performance firefight. OraPub's Oracle ACE Director, Craig Shallahamer, has the depth of experience (20+ years) and engaging teaching style to keep you entertained while you learn how to extinguish your company’s Oracle database fires expediently.

You will be able to:

  • Quickly create a diagnostic framework and discover performance improving opportunities
  • Aggressively use ASH or any ASH-simulator
  • Perform an Oracle Time-Based (DB Time) Analysis using your favorite tool's data, including AWR and Statspack reports
  • Perform a systematic, quantitative and extremely accurate performance diagnosis of even the most complex Oracle database systems
  • Understand deep performance-centric Oracle internals and how Oracle interacts with applications and the host operating system
  • Develop sensible and responsible solutions for the same problem
  • Create an honest and understandable story explaining the problem
  • Use the latest Oracle release-specific diagnostic capabilities available in your environment
  • Know exactly how to move forward, even with stacks of performance data

All queries, scripts, tools, spreadsheets, and templates referenced are free and downloadable at OraPub's website.

Unique

Craig’s courses make Oracle internals come alive while being day-to-day practical. Craig emphasizes using a quantitative time-based approach to maximizing performance from an Oracle, an operating system and an applications perspective. Multiple hands-on case studies are infused into each class from production system AWR reports. The ASH workshops are performed on your laptop while connected to a loaded system. All analysis tools are free and downloadable from OraPub's website. You will also learn how to professionally present and articulate your findings in a clear, concise and effective manner.
