Create service with network capabilities

TobiasLitherland1

Hi,

I need to create a Python script that automatically publishes services with network capabilities. To do this, I use the function arcpy.mapping.CreateMapSDDraft to create a draft from an MXD. The mxd contains network layers, and the service needs to be capable of network analysis, so I need to activate the Network Analysis capability before publishing the service.

What I can't fathom is how to add network capabilities to the service. I see all the examples of how to add KmlServer and WMSServer and Feature Access and what not, but I can't understand which variables need to be set to what for the network capabilitiy, and I can't find any documentation for it.

I also tried checking the differences between the XML code in sddraft files for two different ArcMap-created drafts (one with network, one without), but I was none the wiser. There was just too much code.

Please help, if you can!

Hey Tobias,

Even though the samples don't use the Network Analysis Service capability, the exact same concept applies. You basically just change the soe value to 'NAServer'. The code essentially parses the XML in the draft and sets the "enabled" value for the Network Analysis SOE from "false" to "true".

The following code allowed me to publish a completely functional NA service from an MXD that I have. I used the sample from the Sample 3 in the Help documentation from the CreateMapSDDraft help to build this.

import arcpy, os import xml.dom.minidom as DOM  print "Establishing environment" workspace = r"C:\temp\enableNA" mxd = arcpy.mapping.MapDocument(os.path.join(workspace,"enablenatest.mxd")) svrconnection = os.path.join(workspace, "svrconnection.ags") outsddraft = os.path.join(workspace,"service.sddraft") draftfinal = os.path.join(workspace,"draftfinal.sddraft") outsd = os.path.join(workspace,"naservice.sd")  print "Creating initial draft" arcpy.mapping.CreateMapSDDraft(mxd, outsddraft, "PythonNaTest","ARCGIS_SERVER",svrconnection) soe = 'NAServer'  print "Enabling Network Analysis in the draft" # Read the sddraft xml. doc = DOM.parse(outsddraft) # Find all elements named TypeName. This is where the server object extension (SOE) names are defined. typeNames = doc.getElementsByTagName('TypeName') for typeName in typeNames:     # Get the TypeName whose properties we want to modify.     if typeName.firstChild.data == soe:         extension = typeName.parentNode         for extElement in extension.childNodes:             # Enabled SOE.             if extElement.tagName == 'Enabled':                 extElement.firstChild.data = 'true'                                          # Output to a new sddraft. f = open(draftfinal, 'w')      doc.writexml( f )      f.close()  print "Staging Service" arcpy.StageService_server(draftfinal, outsd)  print "Publishing to Server" arcpy.UploadServiceDefinition_server(outsd,svrconnection,"PythonNATest")
