I wasn't clear in my description. We want both, the ability to place a point on the map and to track where the user was located when the survey was completed. ... View more

We already have a geopoint in the survey. The user adds a geo-point over the asset they are inspecting. How do we know if the user was in their truck, office, or actually at the asset? We don't know. That's why we want tracking. Collector has it why can't Survey123? ... View more

When I say virtual memory, I'm talking about virtual memory in windows server, configured through the control panel. I have no access to the vmware configuration. We went had many discussions on why a windows server should have little to no virtual memory. While in theory, I agree. In practice it doesn't work in my case with arcgis server. I was wrong about my current virtual memory allocation, it is actually 10GB. 5GB was barely enough and it was only semi-stable. More virtual memory and we are more stable. I'm not saying it is perfect but we have fewer crashes these days. Currently my servers are running with 64% physical memory and a commit of 29/44. Does anyone know enough about java to explain why arcgis server uses OS virtual memory? Is it the java virtual machine that is requiring the virtual memory? Can we configure Java to not use virtual memory? ... View more

Patrick, I have seen the resource exhaustion many times before. I ran into it when upgrading a site with 50+ map services on server 10.1, windows 2008 r2, 26GB ram, vmware, 2 servers on 1 cluster. Systems analysts swore that we didn't need more than 1GB of virtual memory. ESRI support couldn't provide an answer as to how much virtual memory was needed, just more. The best part was ESRI support said to let windows manage your virtual memory. Our Systems Analysts said no way in vmware, Ha! I would publish some maps and then the services would crash. Add another Gig of virtual memory and I could publish more services. Progress. We are now up to 5GB of virtual memory. The metric to watch is the commit in task manager on the performance tab. Once this ratio maxes out services will crash. For example, 29/44 ok. 44/44 crash. We now monitor the windows commit. Once this resource exhaustion error occurs, arcgis server is in a bad state and needs to be restarted. When this event occurs, it seems to happen on both servers in the cluster at the same time. The best of my understanding is that Server is running java virtual machines and each jvm/map service requires virtual memory. Each map service that is published uses a little bit more. You can't run out of virtual memory. Frank ... View more
