Currently we have 2 Oracle Databases which holds Water and Electric SDE environments in them. We also have an Arcgis Server environment which host our Tiled Cached Map Services. I want to know is it normal to have a copy of the databases in order to have view only users use. While editors have there own environment. Granted we would only be having 50 at any given time. We roughly have about 200 users who use our HTML Website?
