Performance Tuning with ASH and AWR Data
 
01:03:05
Presented by Kellyn Pot'Vin 30 August 2012 Summary: Since their introduction with Oracle 10g, AWR and ASH data has offered the Database professional enhanced performance reporting capabilities that previously were only gleamed via statspack and reporting queries. In this webinar, Kellyn Pot'Vin, Senior Technical Consultant at Enkitec, will take you through the requirements, reporting basics and differences of AWR and ASH. You will learn: - Reasons to use both reports. - A firm understanding of each report and its format. - Knowledge of the differing versions of the AWR report and when best utilized. - The power of ASH Reporting in real-time trouble-shooting. - Ability to utilize the reports at the command line and from Enterprise Manager. A live Q&A session with Kellyn Pot'Vin follows the presentation. For our complete archive, and to sign up for upcoming webinars please go to http://www.red-gate.com/oracle-webinars

How to Gather SQL Resource Consumption Metrics in Oracle
 
01:20:51
Presented by Karen Morton Tues 8th May 2012 Summary SQL is utilized to return data via our applications to service user requests. Whether it's a single customer lookup or a huge month end summary report, the SQL we write must gather the correct data and return it to the user. Ensuring that the SQL you write can do this in a timely and efficient manner, both now and in the future, requires that you measure and evaluate what resources your query must use. In this webinar, we'll cover several methods for how to collect data that show you precisely how your SQL consumes resources: Using AUTOTRACE Using DBMS_XPLAN.DISPLAY_CURSOR Using Report SQL Monitor Using ASH (Active Session History) and AWR (Automatic Workload Repository) data You'll learn how to utilize the data to understand the work your SQL is doing and the resources it consumes; identify currently evident performance issues as well as areas that could be problematic in the future; and modify your SQL to use less resources more efficiently while still returning the desired results.

Taking Oracle ASH Analysis To The Next Level - Introduction
 
02:00
Sometimes snapshot time-based (AWR) performance data does not provide the level of detail we need to diagnose performance issues. Usually Oracle Active Session History (ASH) data solves this limitation by providing session level sample data. However, we can go further by creatively using ASH data to do things that are not possible using standard ASH and time-based analysis. In this webinar I will show you how to use ASH data to pinpoint SQL plan changes. Also, I will show you how to detect parsing issues before they show up in the wait interface. I'll also include demonstrations and where to get the free SQL, so you can take your ASH analysis to the next level!

Oracle SQL Monitoring - Performance Analysis
 
01:30:41
SQL Monitoring is the best new feature of Oracle 11g for performance analysts, developers and support teams. Finally there is a tool that provides the most accurate, useful and interesting information when a SQL statement is running for longer than expected in a clear format with no minimal advance configuration requirements: What execution plan is really being used? What row source cardinality calculations are incorrect? What steps in the plan are taking the most time and consuming most resources? In this presentation, Doug Burns will demonstrate the various ways of accessing SQL Monitoring functionality and use example reports to show how the information can be used to analyse both currently running and completed statements. It will also describe and offer solutions to some of the minor quirks you might encounter.

Solving Performance Problems on Oracle DB
 
28:11
Solving Performance Problems on Oracle DB Matthew Vegh - Embarcadero Thursday, June 26, 2014 - 11am DBAs and database developers regularly spend a lot of time tracking down and resolving performance issues on the database servers they are responsible for; it can be very difficult, frustrating, and expensive. Given the complex interactions of applications, users and databases, new performance issues can arise almost as fast as old ones can be addressed. This session will simulate common performance problems on an Oracle server and then both identify those problems and provide effective solutions. Matthew Vegh is a Software Architect at Embarcadero Technologies for the Embarcadero DB Power Studio family of products and has been with the company for the better part of a decade. He has over 15 years of development experience with a wide range of technologies and a definite preference for database tooling.

Oracle: How To Optimize Performance When The Top Event Is DB CPU  - Webinar
 
01:18:42
In this webinar Oracle Ace, Craig Shallahamer, will demonstrate how to do an Oracle time based analysis including integrating the OS situation into our analysis and finding the true “top” SQL. This journey includes a trip into Oracle’s library cache, memory access control and some interesting ways to improve SQL statement performance. Overall performance sucks as far as the users are concerned. After months of meetings management finally wants you to get involved. You run an AWR report for one of the most intense hours and notice the top “event” is "DB CPU" followed by "cursor: pin S wait on X”. This is where the webinar begins!

Download the presentation slides, code samples, and a free download of DB Optimizer at http://embt.co/1M7vSe6 Most of us have been in the situation where, for no apparent reason, performance for key SQL takes a nose-dive after having previously performed well. So, how do you handle this situation and stabilize performance back to acceptable levels? One approach is to go back in time using execution data stored in AWR. In many cases, AWR may contain what you need to revert your problem SQL to a better performing alternative.
