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).

Query Tuning 101 Why Use Autotrace
 
01:38
When you're optimizing SQL queries you need to understand what they're actually doing. Explain plan is a commonly used tool with a major flaw - the reported plan and actual plan can be different! This video demonstrates this with a simple query, showing how autotrace reports the correct execution plan for the SQL statement. ============================ The Magic of SQL with Chris Saxon Copyright © 2015 Oracle and/or its affiliates.

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.

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.

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. A live Q+A session with Karen Morton follows the presentation. For our complete archive, and to sign up for upcoming webinars please go to http://www.red-gate.com/oracle-webinars
