Duration: 3 days

SQL SERVER TRAINING OVERVIEW

SQL Server Performance Tuning training class teaches attendees how to tune their indexes, database engine, queries, and other features to achieve optimal performance. Note: This course is designed for administrators who are new to tuning SQL Server , rather than developers.

SQL SERVER TRAINING PREREQUISITES

This course is designed for SQL Server administrators who have prior SQL query writing experience but are relatively new to tuning SQL Server. This course assumes an existing understanding of relational database concepts and general SQL Server administration topics. If your audience has substantial prior SQL Server tuning experience, this course is not recommended.

HANDS-ON/LECTURE RATIO

Due to the theory required to implement many of the performance tuning practices, the first 2.5 days of this SQL Server training is 50 lecture, 50% hands-on, with the longest lecture segments lasting for 60 minutes. If desired, the last half-day is spent tuning and troubleshooting your databases and queries.

SOFTWARE NEEDED ON EACH STUDENT PC

  • 64-bit Windows 7 or later, or Windows Server 2008 R2 or later, with the latest service pack updates and at least 4 GB RAM
  • A full installation of the SQL Server database engine with the latest service packs installed, as well as all client tools
  • Adventureworks database

 

SQL Server Training Objectives

  • Use Windows Performance Monitor
  • Create a performance baseline
  • Collect and analyze SQL Server Extended Events
  • Analyze the performance of SQL queries
  • Analyze and optimize indexes
  • Use the Database Tuning Advisor
  • Examine and correct fragmentation
  • Review execution plans and the execution plan cache for optimizations
  • Analyze the performance of SQL queries
  • Design more efficient queries
  • Detect and reduce or eliminate blocking
  • Catch and solve deadlocks
  • Optimize database workloads
