Tutorial: Database Engine Tuning Advisor

  • Artikel

Applies to: SQL Server

Welcome to the Database Engine Tuning Advisor tutorial. Database Engine Tuning Advisor examines how queries are processed in the databases you specify, and then recommends how you can improve query processing performance by modifying database structures such as indexes, indexed views, and partitioning.

Database Engine Tuning Advisor provides two user interfaces: a graphical user interface (GUI) and the dta command prompt utility. The GUI makes it easy to quickly view the results of tuning sessions, and the dta utility makes it easy to incorporate Database Engine Tuning Advisor functionality into scripts for automated tuning. In addition, Database Engine Tuning Advisor can take XML input, which offers more control over the tuning process.

Note

The Database Engine Tuning Advisor is not supported for Azure SQL Database or Azure SQL Managed Instance. Instead, consider the strategies recommended in Monitoring and performance tuning in Azure SQL Database and Azure SQL Managed Instance. For Azure SQL Database, see also the Database Advisor performance recommendations for Azure SQL Database.
