Updates made to a feature class aren't shown on its associated map service

Description

Sometimes when updates are made to a feature class, those edits don't appear on its associated map service, even after restarting the service.

Cause

This is usually due to the data being copied to the server.

Note:
A warning is also displayed during the publishing process that the data will be copied to the server.

http://<server name>.domain.com:6080/ArcGIS/manager

Solution or Workaround

1. In ArcGIS Server Manager, navigate to Site > GIS Server > Data Store.
2. Depending on the location of the data, either click 'Register Database' or 'Register Folder'. Enter the required parameters and click 'Create'. See About registering your data with ArcGIS Server for further information regarding data registration.
3. Republish the map service and ensure that the 'Overwrite an existing service' option is selected.
   
   

   Note:
   Prior to publishing, notice that the warning is no longer returned that the data will be copied to the server.

   
   If the database was registered with ArcGIS Server, notice that edits made in the database are reflected at the service level almost immediately, without the need to restart or overwrite the service.
   
   If a folder was registered with ArcGIS Server, notice that after restarting the map service, changes made to the data are reflected at the service level.
