Some time back I wrote an article on the new feature that’s added to SQL Server 2012 DTA (database tuning advisor). I have installed SQL Server 2012 on Windows 8 operating system. When I started testing plan cache analysis using DTA , it crashes abruptly with the error message below
DTA stands for Database Tuning Advisor which has introduced from SQL Server 2005. This utility helps the end user to tune their query and give them suggestions for better performance. It takes T-SQL query or profiler trace as workload, based on this it will analyze and give you the recommendation. Now in SQL Server 2012 it has been extended to include plan cache as workload, which means now you can directly point your db plan cache for analysis.
The Database Engine Tuning Advisor is a new tool in Microsoft SQL Server 2005 that enables you to tune databases for improved query processing. Database Engine Tuning Advisor examines how queries are processed in the databases you specify and then it recommends how you can improve query processing performance by modifying physical design structures such as indexes, indexed views, and partitioning. It replaces the Index Tuning Wizard from Microsoft SQL Server 2000, and offers many new features.
