Compatibility issues with Server 10.5+ & Python Windows Services (pywin32)

pfoppe — Sat, 11 Dec 2021 07:11:39 GMT

Our organization has built a few python based windows services to complete some automated tasks; these windows services are installed on the same server running ArcGIS Server so they can use the underlying python deployment and tie into arcpy. These windows services have functioned along side ArcGIS Server quite well until the v10.5 release. At the 10.5 release, we are starting to experience issues. Primarily that...

if the python based windows service is started before the ArcGIS Server service, then all the ArcSOC.exe's fail on launch. We can see the ArcSOC.exe briefly show up taskmgr but they disappear and throw the following exception in the ArcGIS Server manager logs -

To install that service, save it as a file (ex: win_svc_sample.py), install the 64-bit version of pywin32 for python 2.7 and run this command from the windows command line as administrator:

python.exe win_svc_sample.py install‍‍‍

We've tried a variety of things to resolve including:

Installing a virtual environment with the pywin32 modules and creating the service from the virtualenv
Installing ArcGIS Desktop along side server
Tested on both 10.4.1, 10.5.1, and 10.6.1 on windows 2008 and 2012.

We can run a windows service just fine as long as we do not import arcpy. If we import arcpy then the ArcSOC.exe fail to launch. We were able to achieve success by installing ArcGIS Desktop along side the server, and can confirm that if arcpy is loaded from <module 'arcpy' from 'C:\Program Files (x86)\ArcGIS\Desktop10.6\ArcPy\arcpy\__init__.pyc'>

then it will function when co-located on the same server as ArcGIS Server. However, if desktop is not there, then arcpy is loaded from <module 'arcpy' from '<C:\Program Files\ArcGIS\Server\ArcPy\arcpy\__init__.pyc>'then the ArcSOC.exe's fail.

Thoughts from the community?

Is anyone else running python based windows services on the same server as ArcGIS for Server?

Any idea why importing arcpy from a windows service would prevent arcgis server from functioning?

We can move these windows services to a new host running ArcGIS Desktop with background geoprocessing in the short term, however we have larger plans to co-locate with server at multiple locations in the future and would really like to ensure compatibility with server. The error

java.rmi.activation.ActivationException: object activation failed after 2 tries; nested exception is: java.rmi.ConnectException: Connection refused to host: <XX.XXX.XX.XX>; nested exception is: java.net.ConnectException: Connection refused: connect

Suggests a firewall block (all are disabled and this works without the python based windows service) or a different component is failing which is listening for an active connection.

Interesting enough.. if the server is started first, then the python windows service, everything appears to work as expected. Including stopping/re-starting arcgis server services (the ArcSOC.exe do not fail to launch as long as the server is running correctly).

Thanks for any help/advise.

Re: Compatibility issues with Server 10.5+ & Python Windows Services (pywin32)

I tried to add a service dependancy to the ArcGIS Server windows service - Sc config | Microsoft Docs

C:\>sc config "A-arcpy-pysvc-test" depend= "ArcGIS Server"

[SC] ChangeServiceConfig SUCCESS‍‍‍

But the python service starts up much faster than ArcGIS Server and I cannot find a way to set a delay to the dependency. I might be able to put a delay (5 min sleep timer) before importing arcpy and completing the core logic. Still mulling over options...
