Performance Tuning and Optimizing SQL Databases

28 horas

ABOUT THE COURSE

This four-day instructor-led course provides students who manage and maintain SQL Server databases with the knowledge and skills to performance tune and optimize their databases.

IDEAL FOR

The primary audience for this course is individuals who administer and maintain SQL Server databases and are responsible for optimal performance of SQL Server instances that they manage. These individuals also write queries against data and need to ensure optimal execution performance of the workloads.

The secondary audiences for this course are individuals who develop applications that deliver content from SQL Server databases.

Please note: Although this course is within the Microsoft SQL Server 2016 curriculum it is applicable to version 2012 and 2014 as well. Some features are from the later version but the tools and techniques for performance tuning and optimising a SQL Server database and queries are the same for all the versions.

OBJECTIVES

Describe the high-level architectural overview of SQL Server and its various components
Describe the SQL Server execution model, waits and queues
Describe core I/O concepts, Storage Area Networks and performance testing
Describe architectural concepts and best practices related to data files for user databases and TempDB
Describe architectural concepts and best practices related to Concurrency, Transactions, Isolation Levels and Locking
Describe architectural concepts of the Optimizer and how to identify and fix query plan issues
Describe architectural concepts, troubleshooting scenarios and best practices related to Plan Cache
Describe architectural concepts, troubleshooting strategy and usage scenarios for Extended Events
Explain data collection strategy and techniques to analyze collected data
Understand techniques to identify and diagnose bottlenecks to improve overall performance

PREREQUISITE KNOWLEDGE

In addition to their professional experience, students who attend this training should already have the following technical knowledge:
Basic knowledge of the Microsoft Windows operating system and its core functionality
Working knowledge of database administration and maintenance
Working knowledge of Transact-SQL
