Event Details

Who should attend?

Experienced DBAs and Developers.

This is a fast-paced class and attendees should have a good understanding of Oracle.


Designing Optimal SQL- This tutorial has two targets. First: how do you improve the performance of a production system by attacking inefficient SQL; secondly: how do you design a system so that you can get data into and out of it efficiently. For most people, the design has already happened, nevertheless you need to be aware that the two targets overlap significantly - as you struggle to address a particularly inefficient piece of SQL, you need to be aware that there are structural features of the database that may help you find a cost effective solution despite the problems imposed by the SQL itself.

The course will focus on the SQL - falling back to structural issues only as an aid to improving the mechanical efficiency of the SQL solution - but we will spend some time explaining the pros and cons of various structural options as they become relevant to the SQL.

The course will cover methods of reviewing data distribution patterns, use of indexes, use of views (stored and inline), analytic functions, subquery factoring, as well as statistics, hints, and a brief review of execution plans.


Indexing Strategies - One of the most important, yet overlooked, aspects of efficiency is the need for a good indexing strategy.

Indexes improve the speed of queries, but increase the cost of DML. Given a thorough understanding of indexes you have the option for deciding the optimal set of indexes to suit the needs of your application. Everything you might want to know about indexes will be in this tutorial.


Cost-Based Optimization - Is there a go_faster parameter? Which parameters affect the Cost Based Optimizer (CBO) most? Just how does Oracle decide whether or not to use an index? Why does Oracle do a Hash Join instead of a Nested Loop? Why is Oracle ignoring my hints?

All these, and many other questions about the working of the Cost Based Optimizer will be answered by this tutorial.
