Oracle SQL Tuning - How to Read Execution Plans (Explain Plan)
 
13:39
In this free tutorial you will learn how to generate and read (interpret) an execution plan in Oracle Databases. See more FREE Oracle Tuning tutorials at http://skillbuilders.com/free-oracle-tutorials. Understanding what the Oracle Database does with your SQL is essential to tuning - and the execution plan is the key. Oracle Certified Master DBA John Watson will provide a brief introduction (4 minutes) - which includes John's tuning methodology, then demonstrate EXPLAIN PLAN, SQL*Plus AUTOTRACE and DBMS_XPLAN.DISPLAY_CURSOR. In the tutorial, John will teach you: - How to read an execution plan - Find the 1st step in the plan - Decipher the order of the steps in the plan - That EXPLAIN PLAN can be very misleading Prerequisites: To get the most from this tutorial, you should: 1 Know how to code SQL 2 Be familiar with SQL*Plus 3 Know - in very general terms - what an execution plan is. 4 Have a basic understanding of the Library Cache (this is where Oracle Database stores parsed SQL statements) 5 Have a basic understanding of the Cost Based Optimizer (this is the part of the database that parses your SQL, creates an execution plan. Hopefully the correct - most efficient - plan).

Сергей Михалев — Оптимизация SQL-запросов, часть 1
 
01:08:02
Сергей Михалев, VIAcode — Оптимизация SQL-запросов, часть 1 Встреча CodeFreeze в Петербурге, 28.08.2013 В среду, 28 августа в бизнес-инкубаторе «Ингрия» состоялась встреча с разработчиком компании VIACode Сергеем Михалевым. Из доклада слушатели узнали о том, какие проблемы с производительностью могут возникнуть при работе с самыми, казалось бы, обыкновенными SQL-запросами и об оптимизации этих запросов. По ходу доклада мы последовательно рассмотрим несколько весьма непростых ситуаций, все глубже и глубже вникая в область оптимизации запросов. Для этого нам потребуется определённый уровень понимания устройства и работы SQL Server-а, а также глубокие знания в области оптимизации запросов. Несмотря на то, что основой для примеров служит MS SQL, многие аспекты могут быть применены и к другим СУБД. Мы разберемся с такими вопросами как: — жизненный цикл запросов — механизм подготовки, кеширования и исполнения запросов в MS SQL; — основы чтения планов выполнения запросов; — влияние внешних ключей, кластерных представлений и вычислимых столбцов на производительность запроса; — проблема неявного преобразования типов; — статистика сервера и как она может влиять на скорость исполнения запроса. Материал для доклада собран из реальных проектов и задач. Многие примеры выстраданы долгими часами, днями (а то и месяцами) напряженной работы. Доклад будет полезен всем, кто работает с базами данных.

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.

Oracle SQL Tuning - Explain Plan Lies?
 
08:20
Do you use EXPLAIN PLAN to tune Oracle SQL? Does it always "tell the truth", or does it "lie". (Maybe it's not the whole truth!) In this free tutorial from SkillBuilders' Oracle Certified Master John Watson, you will learn why the execution plan generated by EXPLAIN PLAN can be misleading and what to do about it. After a brief lecture, John demonstrates exactly why. You'll hear about dynamic sampling, adaptive cursor sharing (11g), adaptive execution plans (12c) and of course, bind variables. John demonstrates how bind variables cause misleading execution plans using dbms_xplan.display and dbms_xplan.display_cursor. To get the most from this tutorial, you should have some understanding of hard parse, soft parse, cardinality, histograms.

Explaining the Explain Plan: Interpreting Execution Plans for SQL Statements
 
01:04:02
Presenter: Maria Colgan, Oracle Corporation The execution plan for a SQL statement can often seem complicated and hard to understand. Determining if the execution plan you are looking at is the best plan you could get or attempting to improve a poorly performing execution plan can be a daunting task, even for the most experienced DBA or developer. This session examines the different aspects of an execution plan, from selectivity to parallel execution, and explains what information you should be gleaming from the plan and how it affects the execution. It offers insight into what caused the Optimizer to make the decision it did as well as a set of corrective measures that can be used to improve each aspect of the plan.

Query Tuning 101: How to Compare Execution Plans
 
04:12
When you're tuning SQL query there's two important questions to keep in mind: * Have my changes made any difference? * If they have, is performance better or worse? In this video we'll look at how you can use SQL Developer to compare execution plans. This will enable you to differences between them and determine which plan performs better. ============================ The Magic of SQL with Chris Saxon Copyright © 2015 Oracle and/or its affiliates.
