Unsupported Tuning Options

New: 5 December 2005

Database Engine Tuning Advisor graphical user interface (GUI) and the dta utility can be used to tune databases only on the Standard, Enterprise, Developer, and Enterprise Evaluation editions of SQL Server 2005 and SQL Server 2000. However, tuning options involving indexed views, partitioning, and generating recommendations online are not supported on the SQL Server 2005 Standard Edition. In addition, tuning options involving partitioning and generating online recommendations are not supported by any edition of SQL Server 2000, and options involving indexed views are not supported by SQL Server 2000 Standard Edition. These limitations are discussed in greater detail below.
