Hey Amy, It's difficult to give specific best practices related to performance due to the large differences between data, service usage, and environment. With that in mind, a single map service should be adequate in most cases to share one feature class for multiple uses. The number of instances will correlate with the number of cores the service runs on. This can be visualized by opening Task Manager on the server and looking at the ArcSOC.exe processes under the Processes tab. Turning on the Command Line column will help associate each process tied to a specific map service. If your map service is set to a max/min of 2 instances, then there should be 2 ArcSOC.exe processes. The next thing to keep in mind is how many simultaneous users you'll have. I could have a simple web application with one map service and 20 users, but I won't see any performance issues because those users would have a hard time forcing simultaneous requests. From the server's perspective, a request will come in, it will handle that using one of the available instances, and it will return a response. That request/response typically occurs in fractions of a second. As long as the response time is low, your server should not be burdened as the user base grows. The statistics in Server Manager under the Logs tab should give a clearer picture of what is happening in this arena over time. If any of this information is unclear let me know and we can expand on it. Thanks, Scott ... View more

Hey Nick, While I would strongly recommend the Web AppBuilder to develop new applications, it is possible to extend your existing web application in Flex by creating new config.xml files. The link below explains how to specify a separate configuration file (ex. config_1.xml, config_state.xml) within the same application as a URL parameter: ArcGIS Viewer for Flex - Viewer URL parameters Hope this helps in the meantime, but for a long term solution Web AppBuilder is the way to go. Thanks, Scott ... View more

Hey Mike, The sign in model for Collector will rely on the named users for your internal Portal environment. Field workers you will want to access web maps will need to sign in prior to browsing the available maps to collect emergency response data. While Jayanta's solution is a possible scenario, users will still need to have a login to the portal (on-site Portal or ArcGIS Online) where the web map is stored and shared with everyone. This workflow will give everyone the ability to access your web map (even those that you do not want to), but you can use the separate ArcGIS for Server security model to restrict access to the emergency response services that will be edited.

Hey Joe, Is your map service secured? If so, what type of security is configured on your server? Could you install a web debugger such as Fiddler to see what kind of network activity is happening when the popup fails to return information? Fiddler can be found here: Download Fiddler Web Debugging Tool for Free by Telerik Thanks, Scott ... View more

There is an existing idea on our Ideas Site: http://ideas.arcgis.com/ideaView?id=087E0000000CwxB "Change selection color and size (halo) in Collector and ArcGIS Online." If you would like to promote this idea click the link above to join other users in supporting it. As more users express a need for this change, we can begin to get an idea of its popularity and necessity within Collector for ArcGIS. Thanks, Scott ... View more

Thanks for this clarification Vincent. What version of ArcGIS for Server are you using? What version of ArcSDE is being used to store the data as well? Also, what version of Collector are you using? Would it be possible to enable DEBUG logging in Server Manager while you are downloading this data to see if any messages come up there related to the attachment table? Thanks, Scott ... View more

Hey Sanne, Is the web map coming from Portal or ArcGIS Online? Where are the feature services hosted, Online or Server? Also, does this occur on a cellular network as well as wifi? Thanks, Scott ... View more

Can you enable DEBUG level logging on the ArcGIS for Server to see if we can get more information related to this error? This will be in Server Manger under Logs>Settings. Also, what DBMS are you using, and what version of ArcGIS for Server/ArcSDE? Is this server federated with a Portal? Thanks, Scott ... View more

Hey Vincent, Is your feature service hosted on ArcGIS Online or on an ArcGIS Server? This may help us determine how to approach the issue. Thanks, Scott ... View more

Hey Jacqueline, It may be helpful to see what is happening over the network when this issue comes up on Android while on wifi or when trying to download your data for disconnected editing. Could you set up Fiddler as a proxy as outlined in this blog: http://blogs.esri.com/esri/supportcenter/2011/12/06/configuring-fiddler-to-capture-web-traffic-from-an-iphone-ipad-device/​ The settings will be accessed differently on an Android device, but the concept should work in the same way. Once we can view the traffic through Fiddler, we might get a better idea of what is going on. Additionally, can you bump the logging on the ArcGIS for Server up to DEBUG level? While downloading data in Collector for disconnected editing, this can sometimes shed a little more light on what is happening from the server's perspective. Thanks, Scott ... View more

Hey Emily, It can definitely be helpful to separate layers and try to isolate any problematic ones in their own feature service/web map. This can help determine if the performance issue you are encountering is data specific, or if it is elsewhere. When this data is successfully downloaded to your device, what is its size on disk? This can be found by connecting the device to your computer and going through iTunes for iOS or a file explorer for Android. In the directory for ArcGIS Collector, there should be an "offline_data" folder. In here, there will be folders for each user that has logged in and downloaded data for disconnected editing. Within the user's folder, there will be other folders corresponding with each web map that has been downloaded for disconnected editing. Could you tell me the size of the folder associated with your problematic dataset? Thanks, Scott ... View more

Hey Pete, How large is the area of interest being downloaded, and how many features/attachments are being downloaded? Do you have any related tables in your feature service? Best practice is to only download an area relevant to the field worker's task. Downloading too much data can be unnecessary, and depending on surrounding field workers this can cause feature conflicts in the sync process. That isn't to say that the behavior you are seeing is expected. I would recommend you continue working with support to uncover what exactly is causing the slowdown in your environment. -Scott ...

Hey Francis, This sounds like it could be a good suggestion for the future of Collector for ArcGIS. Have you taken a look at http://ideas.arcgis.com to see if it already exists? If it is not already there, you can write it out and tag it appropriately to get further input from the community. Let me know if you have any questions. Thanks, Scott ... View more
