We are considering adding geoprocessing services on our ArcGIS Server infrastructure, and wondering what others' experiences were.  Effect on performance is the biggest concern.  I realize there are lots of variables there, but a specific use case would be a service which buffers point data.  We currently have a single server site but expecting to bring a second server online soon.  Alternatively considering using ArcGIS Online geoprocessing services, although that consumes credits.  Wondering what others have done.  Is there a reliable way to estimate performance impact, given an anticipated use case? ...

Our master geodatabase, on SQL Server, contains data layers that  are maintained on a separate file geodatabase, and are replicated on the master database.  We would like to create attribute indexes on those layers in our master geodatabase.  The question is, will synchronization and replication break or cause problems with those attribute indexes when the data updates are pushed from the file geodatabase? ...

We have downloaded the ESRI Image Discovery app and will be deploying it with our image services.  We would like to tweak a few features of this app.  I have already reviewed these documents but couldn't find what I was looking for: http://solutions.arcgis.com/defense/help/image-discovery/get-started/personalize-app/ https://github.com/Esri/image-discovery-app-js/blob/master/documentation/discoveryViewerConfigurations.md Here are some example of the modifications I want to make: Setting a default layer opacity value on the imagery Change the Find Address search units from meters to miles Identify tool- can it be configured to select by point or line as well as poly?

Can this be done, if so, how would I write the URL for that download? ... View more
