When publishing a map service, the result of the analysis is that some data sources have no spatial index. Advanced warning.

Spatial indexes can speed up drawing. Index, you don't have to say much. So how do you build a spatial index?

Search on Google, see the help of ArcGIS, such as Fall Yun in. The extent of its correct nonsense, is on the MSDN. Fortunately at the end did not ask you a sentence: Do you think the above content is helpful to you.

A blog post describes an example of manually creating a spatial index of SQL statements in Oracle, but to specify the table name, field name, Ah, what a huge amount of work. Moreover, for me this is not a beginner of GIS beginners, basically ignorant, how do I know which fields to build spatial index. I don't even know what a spatial index is.

Later found that, double-click the analysis results, will pop up the corresponding dialog box, such as the figure, press the "OK" button, the system can create a spatial index for you.
