ArcGIS GeoEvent Server 10.5  was working fine since I installed it two weeks ago, but it stopped working after I restarted the computer last night.  When I tried to access the GeoEvent Manager, I get "The webpage cannot be found" message.  And, I checked the karaf logs and here is what the errors are: 2017-04-14 19:21:54,678 | ERROR | pool-11-thread-1 | Http | 95 - com.esri.ges.framework.httpclient - 10.5.0 | An SSL Handshake error has occurred when attempting to communicate with URL: "https://[ServerName]:6443/arcgis/admin/system/configstore".

The GeoEvent Server is installed and configured exactly described in Installing GeoEvent Server—Installation Guides (10.5) | ArcGIS Enterprise, and with self signed certificate.  Any ideas how can fix this?

I am using GeoEvent to process AVL data and store the data in an Geodatabase.  Often, I found the data are not stored in the same order as they are received. I am curious to know how GeoEvent is maintain ordering of events when multiple events are read at a same time? I setup a simple GeoEvent service where an input connector reads from a JSON file (about 500 JSON objects) and connected to an output connector which writes to another JSON file. My assumption is the output JSON file would match the input JSON file exactly. But, the test proves otherwise; the order of events in the output file is not the same as input. Could someone help me understand why the ordering of the events would change? Thanks, Roman ... View more

Is it possible to add/update feature class from a JSON feed below: {    "cars": [{       "manufacturer": "Honda",       "attribute": [{             "Label": "Name",             "value": "Accord"          }, {             "Label": "Year",             "value": 2007          }, {             "Label": "Weight",             "value": 3000          }]       }, {          "manufacturer": "Toyota",          "attribute": [{             "Label": "Name",             "value": "Camery"           }, {             "Label": "Year",             "value": 2010          }, {             "Label": "Passengers",             "value": 5          }]     }] } A GeoEvent definition was created after I created an Input connector consuming the JSON. How do I map this GeoEvent so that I can update to a Feature Class through a feature service with fields: Manufacturers, Name, Year, Weight, Passengers? Thanks ... View more

I would like use ArcGIS Data Store for my services, and I am wondering if there is any way to create a Database connection from ArcCatalog or ArcMap to the PostgreSQL database? ... View more

On one server I have ArcSDE running in SQL Server 2012 (SP2), and another server I have ArcGIS 10.3.1 Server hosting a feature service that access the ArcSDE database.   The feature service runs fine until I see the following error message in the ArcGIS Server log: Error: Failure to access the DBMS server [08S01:[Microsoft][SQL Server Native Client 11.0]TCP Provider: An existing connection was forcibly closed by the remote host. And then the following error message on every feature service request: Error: Failure to access the DBMS server [[Microsoft][SQL Server Native Client 11.0]Communication link failure] It seems database connection was temporary disconnected, and  the only solution is to restart the service manually.  My question is:  Why wouldn't the Feature Service reconnect with ArcSDE?  Is there anyway around this beside restart the service manually?
