Microsoft SQL Server 2012 Performance Tuning Cookbook

Chapter 2. Tuning with Database Engine Tuning Advisor

In this chapter we will cover:

  • Analyzing queries using Database Engine Tuning Advisor

  • Running Database Engine Tuning Advisor for Workload

  • Executing Database Tuning Advisor from command prompt

Introduction


Database Engine Tuning Advisor (DTA) suggests ways to tune the database by analyzing the Workload provided. DTA helps in creating an efficient index, an indexed view (if it's supported by the SQL Server Edition you are using), statistics, and partitions. DTA can give efficient suggestions only if you have created proper workload with sufficient data. For further details of creating workload, refer Creating a trace or workload recipe of Chapter 1, Mastering SQL Trace Using Profiler.

Studying an Estimated execution plan (covered in Chapter 5, Monitoring with Execution Plans) of query from Query Editor to find out the bottleneck and resolve it needs knowledge of the database structure as well as good command over performance tuning, whereas DTA offers a very simple solution to this. Just collect the proper workload, give it to DTA and it will analyze that Workload for you and suggests you the ways for tuning.

Sometimes it happens that we tune one query by creating/removing an index...

Analyzing queries using Database Engine Tuning Advisor


There are few different ways that can help you in providing workload to DTA. One of the popular ways is to ask DTA about the query you are designing at the moment for performance point of view, so that DTA can analyze the query and provide suggestions, if any.

Getting ready

We will need two tables to demonstrate this recipe. Here is the script to create the same:

USE AdventureWorks2012
GO
IF OBJECT_ID('ProductDemo') IS NOT NULL
DROP TABLE ProductDemo
GO
IF OBJECT_ID('ProductModelDemo') IS NOT NULL
DROP TABLE ProductModelDemo
GO
select * into ProductModelDemo from Production.ProductModel
select * into ProductDemo from Production.Product
GO

We have just created two tables, named ProductDemo and ProductModelDemo, which don't have any index or statistics right now.

How to do it...

Now here is the query we want to execute and tune if possible:

SELECT
P.ProductID
,P.ProductModelID
FROM
ProductDemo AS P
JOIN
ProductModelDemo AS PM
ON
P.ProductModelID...

Running Database Engine Tuning Advisor for workload


Trace is a session during which the events are captured and event data is collected. SQL Server supports a few formats for saving this collected trace data, which is known as a workload. We can save trace data (a workload) in one of the following formats:

  • A trace file with .trc extension name

  • A trace file in XML format with .xml extension name

  • A trace table in an SQL Server database

We are going to use trace file .trc for this recipe. For detailed information regarding trace, workload, and different events of trace in profiler, refer Creating a trace or workload recipe in Chapter 1.

In this recipe, we will create a trace with SQL Server Profiler; execute some queries that will be captured in running profiler trace file and load that trace file in Database Engine Tuning tool to analyze the workload.

Tip

It is recommended to use server-side trace over profiler use on a production server as profiler can consume lot of network bandwidth resources...

Executing Database Tuning Advisor from command prompt


There is a command prompt version of Database Engine Tuning Advisor, which is known as DTA. Like a Database Engine Tuning Advisor, DTA also analyses the workload given to it in the form of trace file, table, or query. There is no difference in tuning activity or the suggestions it provides. The visible difference is that Database Engine Tuning Advisor provides GUI and DTA provides a traditional approach. Apart from that, DTA gives you the liberty to provide XML file, if you don't like to type down all parameter on command line.

If you have the same database structure in your development environment as you have in production server with very less data in development environment, you can copy the production instance's index statistics and metadata. This effectively recreates a target environment without the need to migrate a volume of data onto a development server. DTA creates a shell database that you can tune by using the TestServer...

Hi,I have written a detailed chapter-by-chapter review of this book on www DOT i-programmer DOT info, the first and last parts of this review are given here. For my review of all chapters, search i-programmer DOT info for STIRK together with the book's title.Each recipe in this collection is largely self-contained, making it easy to provide a targeted approach. This is good if you know what you're looking for, but often when you're starting out, you don't. Experience helps, so does reading the whole book.Each chapter starts with a short introduction to the topic, and contains between three and eight recipes. Each recipe contains sections for:- getting ready- how to do it- how it works- there's moreMost recipes are run against the freely downloadable Adventure Works 2012 database, this makes it easy to follow along with the recipes yourself. Below is a chapter-by-chapter exploration of the topics covered.Chapter 1 Mastering SQL Trace Using ProfilerAlthough SQL Server Profiler is deprecated, meaning it will be removed from future versions of SQL Server, it is a well known and much used tool for troubleshooting problems. The recipes here walk you through setting up a trace, filtering events, and detecting slow queries - all via the GUI. Additionally, the T-SQL equivalent is also provided. Overall the chapter is easy to read, explains things very well, with more than enough detail to get you started troubleshooting database problems....ConclusionThis is a wide-ranging book, with sufficient instruction to get most SQL developers/DBAs started on investigating performance problems. It's a very practical book, typically providing detailed step-by-step walkthroughs for each recipe/topic, and makes good use of screenshots.There's some nice incidental information provided along with the recipes, and plenty of pointers on where to find further information. Because the topics are largely distinct, there is limited interlinking of recipes/topics.Although the book purports to relate to SQL Server 2012, much of it is equally applicable to SQL Server 2005 and 2008.Unfortunately, the book contains several areas of substandard English grammar. If you can tolerate this, the book can be a good read. Personally I think the book's editors should have been fired!

I have skimmed through the book using Amazon's "Search inside" feature. There are many useful tips, but reading is made difficult by the fact that the English grammar used throughout the book is often improper. It is clear that not enough editing went into the book or perhaps the author's use of English was so horrid that the editor(s) gave up at some point and "let it ride."
