Database Engine Tuning Advisor (Recommendations Tab)

The Recommendations tab appears after Database Engine Tuning Advisor completes analysis of a workload. This grid contains the recommendations for each object considered. Partition recommendations, if any, are presented in the upper grid, and the index recommendations are presented in the lower grid. The grids do not appear if there are no recommendations.

The Definition column contains the definition of the recommended partition or index as a hyperlink. This column is usually too narrow to see the entire definition. Click the hyperlink to display a dialog box containing the full definition and the Copy to Clipboard button.
