Sites is designed to work with the content and services within your ArcGIS Enterprise deployment and will allow you to make this content accessible through sites and pages created with ArcGIS Enterprise Sites. Types of content and services you can use with Sites include: hosted layers within the Enterprise portal, services from the servers you have federated with ArcGIS Enterprise, and services that have been registered as items with the portal.
Below are some best practices for configuring service properties:
Max record count should be less than 5,000
When publishing a service, a default max record count of 1,000 or 2,000 is set and intended to provide optimal performance from your server to the client. The max record count determines the maximum number of features that can be returned in a single request. When a service has this set too high, a client can try to request all the data in a single request that is slow to generate and too large to send across the Internet.
It may make sense to increase the value over the default range if you have just over 2,000 or around 4,000 features total in your layer or table.
It’s important to note that no matter the max record count, ArcGIS Enterprise Sites will query out all the data 1,000 records at a time and aggregate it to support file downloads into CSV, KML, SHP, or GeoJSON.
WMS, WFS, and WCS links are added to the API section of the item view on each site when a service publisher has enabled them on the specific service. If the publisher did not enable these capabilities at the time of publishing, they can edit the service and turn them on. Please note that OGC links will only appear on services from ArcGIS Server 10.2 or higher.
Feature Access is not necessary
ArcGIS Enterprise Sites queries features out of the Map Service the same way it queries features from a Feature Service. Unless you have another need to have Feature Access enabled, it is best to leave it off.
Scale dependencies do not matter
SitArcGIS Enterprise Sites works by sending requests to your Map or Feature Services and querying out the data regardless of the extent. While cartographically thinking you may not want to show address points at a global scale, ArcGIS Enterprise Sites will query out all the data and provide high-level visualizations of the data by showing a summary of locations or a gridded visualization that can be filtered and shows the density of features. These visualizations are not customizable.
Download support on Sites
Download functionality is enabled on any uploaded file (image, PDF, and more) and on any hosted layer that supports the extract capability. If you share an item from a service that does not support extract then download is disabled with a tool tip.
Below are some best practices for organizing services:
Large services will time out
Organizing your data in multiple services will be faster than having all data in one service. For the best performance from ArcGIS Enterprise Sites it is recommended to have no more than 20 layers per service.
Managing the data
The following best practices will help your data display in a consistent and user-friendly format.
It is recommended that you enable editor tracking so that you can ensure that users are always receiving the most up-to-date data
Coded value domains are supported
Contrary to the previous section, there is one behavior of the geodatabase that is supported when generating the open-machine-readable formats. Coded Value Domains will be honored when viewing data in ArcGIS Enterprise Sites, and when the data is downloaded, the raw values will be replaced by the coded value.
