Setting up spatiotemporal data store in Amazon EC2

JesseAdams

I'm running into an issue with trying to setup the spatiotemporal arcgis data store on an Amazon EC2 instance. Currently I have two servers setup; one with a base deployment of ArcGIS Enterprise (with ArcGIS Server federated with Portal), and a second with ArcGIS Server licensed as a Geoanalytics Server. Federating the Geoanalytics server with the Portal instance worked just fine. I'm trying to setup a third instance for storing the spatiotemporal data store. I have the data store successfully registered with the hosting server, however, the hosting server is not able to communicate with the data store server. It looks like when data store is registered with server it uses the machine name of the data store:

This won't work since the hosting server can't find the data store by machine name. I've tried changing the machine name to the public amazon DNS and the private DNS. Neither of those work. Validating the connection after updating to either of the DNS names throws a token error:

Is there a setting on the data store machine that I need to update so server can use the DNS name instead of the machine name? Any suggestions would be great.

Thank you,

Hi Sagar,

I tried restarting the hosting ArcGIS Server service after making the ip address update through the admin API on the hosting ArcGIS Server machine. Unfortunately that doesn't seem to make much difference. The validate function still returns "invalid token." I tried re registering the data store with the hosting server using the internal IP but unfortunately the result is the same with the checking the validation. Is there a recommended setting in the windows host file for the ArcGIS Data Store machine? I've tried machine name, IP, and machine name with fake domain name.

Thanks for the help.

Hi Jesse,

Looking at your second screenshot, it appears that the system still looks for hostname from the data store machine.

However, from the hosting server (first screenshot) it appears that you've updated to IP address instead of the hostname.

Is it possible, for you to restart the hosting ArcGIS Server service after this change. (if you haven't already restarted)

Also, instead of the public IP of the BDS machine, can you try the internal IP in the JSON and then restart the hosting ArcGIS server service.

Thanks,

Hi Sagar,

Thank you for the additional suggestion. Unfortunately that didn't seem to resolve my issue. I updated the hostidentifier.properties file to use preferredidentifier of "ip". After the update I restarted ArcGIS Data Store on the BDS machine. I still receive the following message:

I also tested the ports using telnet and the BDS server has access to 6443 on the hosting server and the hosting server has access to 2443, 9220, 9320 coming from the BDS server.

Another thing I tried was to verify the datastore from the BDS machine using the "describedatastore" command:

Are there other ports that need to be accessible to BDS other then 6443?

Let me know if you have other suggestions.

Thank youk,

Hi Jesse,

By default, after installation, ArcGIS Server will point to a spatiotemporal big data store using the internal hostname (e.g. WIN- KI1388PECAS4) on the Big Data Server.

For ArcGIS Enterprise deployments on Amazon and Azure instances, the hostname must be changed to the internal IP address of the Big Data Server via the ArcGIS Server Administrative Directory on the GIS Server at https://<GIS Server.domain>.com:6443/server/admin.

If there is an issue with the internal IP, then you can try the public IP of the BDS machine.

Updating hostname to internal IP of data store machine in the BDS JSON

If the above steps do not fix your issue, then you should check the hostidentifier.properties file under the installation directory of data store which is \Program Files\ArcGIS\DataStore\framework\etc\

If the last line in this file (preferredidentifier=ip) is commented, please uncomment it (by deleting the # and saving it).

uncommenting preferredidentifier=ip line in hostidentifier.properties for BDS on cloud

This will ensure that the hosting server will look for BDS machine's IP address instead of the hostname.

Hope this helps !
