The Spatial Index Advisor application helps database administrators to analyze and tune Oracle Spatial indexes, to achieve good performance for spatial queries. The application lets you analyze layers of spatial data (type SDO_GEOMETRY). The data represents objects such as rectangles, circles, polygons, and arcs, all of which are displayed graphically.
Spatial data can have a spatial index associated with it. A spatial index contains a set of tiles, and the DBA controls the size and number of tiles. The coverage of the geometries by the tiles has a direct impact on query performance. This application lets you see the interaction of the tiles with the geometries.
Important: To use this application, you must understand the major concepts and techniques documented in the Oracle Spatial User's Guide and Reference. The Help information for this application does not describe Oracle Spatial concepts, data types, and functions.
For important information about the current release of this interface, see the "readme" file (text or HTML) that was installed with the software. The location is platform dependent.
A separate topic provides information about using the application interface (window, toolbar, Tips area, and so on).
