Errors in standalone script when copying Route Event Layer to fgb

JeffTrudnak — Thu, 23 Jul 2020 21:02:03 GMT

I am working on a standalone python script that dissolves speed data across a network to perform a daily refresh a table in our enterprise geodatabase. I've made the script work several ways when running in the ArcCatalog python window. I am running into errors when trying to run as a standalone script. Pretty much generic error codes as noted in the abbreviated script below. I've tried specifying the event route layer be written to the current workspace and scratch workspace. Any suggestions? Working in 10.7.1. 32 bit execution in catalog and stand alone. Relatively new to python. Thanks.

arcpy.env.overwriteOutput = True

db_connect = r"Database Connections//GIS on GISD.sde"
arcpy.env.workspace = r'\\GIS_SEVER\Workspace\Speeds_Dissolve\Speeds_Working.gdb'

outFGB = r'\\GIS_SERVER\Workspace\Speeds_Dissolve\Speeds_Working.gdb'
scratchFGB = r'\\GIS_SERVER\Workspace\Speeds_Dissolve\Scratch.gdb'
ToTable = db_connect + "\GDP_OWN.O_SPEED_SEGMENT_DIS"

#define tables
#multiple tables
speed_dis = outFGB + "\speed_dis"
speed_lrs_dis_lines = outFGB + "\speed_lrs_dis_lines"
speed_mrel = scratchFGB + "\speed_mrel"

result4 = arcpy.GetCount_management(speed_mrel)

Hi Jeff,

A few suggestions:

Try to change your path to the full path. Instead of:

db_connect = r"Database Connections//GIS on GISD.sde"

which will work from within Catalog, try something like:

db_connect = r" C:\Users\USERNAME\AppData\Roaming\Esri\ArcGISPro.......sde" (you can get the full path from the sde properties window)

Note that in line 4

GIS_SEVER

I assume it should be

GIS_SERVER

Add two backslashes or r in path. Instead of:

speed_mrel = scratchFGB + "\speed_mrel"

Write:

speed_mrel = scratchFGB + "\\speed_mrel"

speed_mrel = scratchFGB + r"\speed_mrel"

Hope this helps,

Uri

Thanks for the suggestions. I tried multiple ways of specifying the path, but still no luck with exporting the Route Event Layer to the fgb. The script successfully reads from the enterprise db, creates and copies query layers to the fgb, creates and copies a table view from/to the fgb. I just don't know what is different between the route event layer and the other in memory tables that are working without issue. I've tried handling the route event layer the same way as the query layers/table view where I don't specify a full path. I find it interesting that the copy features command is creating the table in the fgb before failing.

speeds_lrs_errors = outFGB + "\speeds_lrs_errors"
speed_mrel = scratchFGB + r"\speed_mrel"
arcpy.MakeRouteEventLayer_lr(mp_detail_lrs,"ROUTE_I", speed_dis, props,"speed_mrel","#","ERROR_FIELD")
arcpy.CopyFeatures_management(speed_mrel,speed_lrs_dis_lines)

works in catalog, as standalone creates speed_lrs_dis_lines in FGB then fails
--
speeds_lrs_errors = outFGB + "\speeds_lrs_errors"
speed_mrel = scratchFGB + r"\speed_mrel"
arcpy.MakeRouteEventLayer_lr(mp_detail_lrs,"ROUTE_I", speed_dis, props,"speed_mrel","#","ERROR_FIELD")
arcpy.Append_management(speed_mrel,speed_lrs_dis_lines,"NO_TEST")

works in catalog, fails as stand alone
--
speed_lrs_dis_lines = outFGB + "\\speed_lrs_dis_lines"
speed_mrel = scratchFGB + "\\speed_mrel"
arcpy.MakeRouteEventLayer_lr(mp_detail_lrs,"ROUTE_I", speed_dis, props,"speed_mrel","#","ERROR_FIELD")
arcpy.CopyFeatures_management(speed_mrel,speed_lrs_dis_lines)

So there was nothing wrong with the script itself. The python script resides on one of our servers used for scheduled jobs. I had access to a shared directory on the server, but could not login to the server. I had been trying to execute the script from my workstation by accessing the shared directory. When I asked our server admin to run the script while logged into the server, the script ran without issue. Again, not sure why this is an issue for the event layer when working with the query layers in the script before the event layer were successful.
