SpConfigUtility.exe
To add components to particular web applications or site collections, use the -url parameter (e.g. "spconfigutility -install -url http://localhost:1234"). Multiple urls may be specified in one command (e.g. "spconfigutility -install -url http://localhost:1234 -url http://localhost:5678"). If the url is that of a web application (or site collection at a web application's root), then the ESRI Parts will be activated on each site collection within the web application. If the url only specifies a site collection, then the ESRI Parts will be activated only within that site collection
Since ArcGIS Mapping for SharePoint is built on the Microsoft Silverlight platform, IIS must also be configured so that it includes the following MIME types:

.xbap application/x-ms-xbap
