Tuning Oracle systems using data from an AWR or Statspack report is powerful. However, there are some challenges that make this typicallly straightforward analysis very problematic. In this webinar I will discuss some of these challenges including how to properly deal with them. The specific challenges are when to use on demand or non-standard snapshot durations, when DB CPU is suspect, when the top event is db file sequential reads but there is NOT an IO bottleneck, why multi-block and async read wait times are typically much longer than single block reads, when backups are run during key batch processes and finally how using ASH data we can help get around some of these problems. You will see all of these challenges come into play while I do an Oracle Time-Based Analysis (OTBA) from a single real-life production Statspack report.

Using Skewed Performance Data To Your Advantage is an important seminar for all DBAs because EVERY Oracle DBA has experienced the effects of skewed performance data, but most don't know how to use that knowledge to their advantage. Have you ever had different groups of users experience different response times from the same exact SQL? Has your IO Admin said the IO response time is fine, but you know single block IOs are taking around 25ms? If you have experienced something like this, then you have likely experienced skewed performance data. I designed this seminar so you will know exactly how to avoid this situation of skewed Oracle wait times and SQL elapsed times. I will teach you how to gather the appropriate data, understand the data and visually demonstrate the situation. This seminar is going to have a deep impact on your Oracle performance work. The skills I teach you will help you devise a sensible solution. Join me for a practical and entertaining journey as we explore the truth about elapsed times and wait events times, turning a potential disaster into your advantage. For details go to http://www.orapub.com/video-seminar-skewed-performance-data This contains eight modules: 1. Introduction: Revealing deception (this video) 2. Understanding your data 3. Common histograms in Oracle performance analysis 4. The problem: Skewed wait times 5. My advantage: Using the skewed wait times 6. The problem: Skewed elapsed times 7. My advantage: Using the skewed elapsed times 8. Resources and seminar close What you will learn: * Know what skewed data is * Be able to communicate why skewed data is a serious problem * Be able to recognize skewed data * Know how to gather individual wait event occurrence times, not average * Know six ways to gather individual SQL execution times, not average * Understand, demonstrate and communicate if skewed data is a problem * Recognize the five common statistical distributions * Be able to describe data using one picture and two statistics * Know histogram construction details * Know how to use the difference between the mean and median * Be able to install and use the free stats package, R * Be able to use the difference between the mean and median * Know how a histogram can cause faulty thinking * Understand why v$event_histogram deceives * Be able to use an AWR and Statspack report to recognize skewed data problems * Know how to create a proper SQL execution time histogram * Know how to create a proper wait event occurrence histogram For more information: http://www.orapub.com

Two Queue Or Not To Queue, That Is The Question will help you tune Oracle systems faster and with a greater depth of understanding. The insights you gain provide both a tactical and strategic performance tuning advantage. From driving in traffic to being served at a restaurant, every person feels the impact of queuing theory. Queuing theory beautifully relates time and work into experiences we can feel; like utilization, workload intensity, response time, elapsed time, user experience and systems architecture design. Queuing theory can be well...theoretical! But Oracle ACE Director Craig Shallahamer turns this topic upside down making it a fantastic learning experience. For details go to http://www.orapub.com/video-seminar-to-queue-or-not For details on OraPub go to www.orapub.com Modules 1. Setting The Stage 2. You Can't Escape A Queuing Theory World 3. The Work And Time Relationship 4. Craig's Hamburger Stand - Definitions 5. Utilization Explored 6. Response Time Explored 7. Going Deeper Part 1 - CPU and IO Subsystems 8. Going Deeper Part 2 - Changing Parameter Values 9. How Queuing Theory Is Used By DBAs 10. Seminar Close What You Will Learn - How to tune Oracle systems faster by understanding queuing theory - How to merge queuing theory into Oracle database performance tuning - What truly is response time - How response time relates to workload intensity, utilization... user experience - How to explain a performance incident from a practical queuing theory perspective - How every person is immersed in a queuing theory world - How an Oracle time-based analysis intimately relates to queuing theory - Why increasing an Oracle workload can hurt performance - How to understand the classic response time curve - How the response time curve relates directly to SQL elapsed time - What are the key queuing theory parameters - Why performance slows when CPUs and IO devices get busy - How to get the busyness for your CPU and IO subsystem - How to calculate the CPU subsystem utilization from v$osstat - Why CPU and IO subsystems are different queuing systems - What happens when we tweak queueing theory input parameters - How is utilization and response time are affected by more or faster CPUs - How does adding more IO devices affect SQL statement elapsed time - How does queuing theory relate to a SQL statement's elapsed time - Why pushing more work through your Oracle system consumes more CPU and potentially more wait time - How can I determine the response time for a SQL statement - How queuing queuing theory relates to performance tuning - How queuing theory parameters relate to my Oracle database activity - How applying queuing theory focuses my performance tuning solutions - How queuing theory can be used in forecasting and predictive analysis - How can I tell if a performance solution is bogus using queuing theory - How can I pick better tuning solutions using queuing theory - How I can use my AWR or Statspack report from a queuing theory perspective
