Allow pre-caching of data layers in Esri Business Analyst Server

Summary

Instructions provided describe how to allow pre-caching of data layers in Esri Business Analyst Server.

Pre-caching data layers helps to improve performance of reports and analysis in Esri Business Analyst Server. When pre-caching is enabled, data is pre-loaded into memory when the service is started, making the data readily available for queries. With pre-caching enabled, the Business Analyst Map Service may take longer to start than it does when pre-caching is disabled, but performance during use is significantly better.

Procedure

1. Open BAServerConfig.xml in a text editor.
2. To enable pre-caching for all data layers in Business Analyst Server, add the following line of code:
   

   Code:
   <PreloadData enabled="true" preloadAll="true" ttl="-1" />

   
   
   
3. (Optional) To pre-cache a specific layer in a Business Analyst Server dataset, indicate the layer and dataset. For example:
   

   Code:
   <PreloadData enabled="true" preloadAll="false" ttl="-1" >
        <dataset id=”USA_ESRI”/>
             <layer id=”US.BlockGroups”/>
        </dataset>
   </PreloadData>
