Hello - I just heard in a workshop that the Utility Network does "not work well" with data in a geographic coordinate system. I thought this was supposed to be one of the advantages of the Utility Network compared to a geometric network. Could anyone elaborate? Thx, Ed

Hello - Am creating annotation expressions for a new Geodatabase that will be maintained both by desktop applications and by services published via ArcGIS server. My understanding had been that VBScript was *not* recommended for this as it may not be supported by ArcGIS Server and thus have pursued building expressions in Python. However, in testing the Python expressions I've found inconsistent results. For example, anno is not always updated when a driving attribute value is changed for an anno class that has a complex Python expression. Then I found a NIMBUS bug related to use of Python for anno expressions (below). So.. now I'm looking for an authoritative direction on a preferred scripting language for annotation expressions. Any feedback on this would be much appreciated. Thx, Ed NIM101020: When an advanced Python label expression for an anno..

Am setting up an environment with a versioned production editing instance and an un-versioned replica instance that will be used for view-only users. The production instance will have a geometric network the replica instance will not. We want to establish archiving on the replica instance for a number of business reasons. My question is: would or how would archiving on the replica instance be affected if we find a need to un-version and then re-version the production instance? Any comments would be much appreciated. Thx, Ed

George - Thanks for this link. Says Oracle 12.1.x.x is supported but what I'm really looking for is whether Oracle 12.2.x.x is supported. At 12.2 Oracle adds support for table and column names longer than 30 characters. Ed

Is Oracle v12.2 supported for ArcGIS 10.2.1? (Sorry to ask but can't find a set of certified versions anywhere else.) Am particularly interested to know if we can take advantage of the larger table/column naming available with Oracle 12.2. Thx, Ed

Robert - That was it! I bounced Pro between staging the utility network and applying the asset package and it completed successfully. Much appreciated! Would be good if Esri added this step to their process. Ed

Did not bounce Pro after closing. Per your suggestion will try re-creating the database from scratch and try again. Thanks much for the info! Ed

BTW... at first I thought the problem was that I had a map open while running the GP tool, which the instructions clearly indicate not to do! However I deleted the utility network, re-ran the "Stage Utility Network" tool (which worked) and re-ran "Apply Asset Package" with the Pipeline_AssetPackage.gdb with no map open and got the same results.

Tried applying the Asset Packge gdb downloaded from UPDM site after staging a new Utility Network. After running quite a while this failed with a message that a table is already locked. This is a new database and new utility network. Any suggestions would be much appreciated. Thx, Ed

Whaddya know... Removed the \ from the list and that seems to have resolved my problem. Thank you so much! Ed

Hi - Am trying to add a field to multiple classes in a File Geodatabase in ArcCatalog with a python script (below.) The script periodically errors on AddField_management returning a "General Function Failure". After the error I can't open the class and receive a "Can't edit object(s)" message box. I've made sure that all classes are OK (can be opened and inspected) prior to running the script. So, I'm pretty sure there is something about the script that is causing a problem. At first I though it might be the number of items in the class name list -- it seemed to fail on processing the 20th item. But now I'm not so sure. Any insights on this would be greatly appreciated. Thanks, Ed import arcpy #Set the connection information arcpy.env.workspace = "C:\Projects\Pilot_Test.gdb" def FieldExist(featureclass, fieldname😞 fieldList = arcpy.ListFields(featureclass, fieldname) fieldCount = len(fieldList) if (fieldCount == 1😞 return True else: return False try: ######################################################################## # Field properties for all new fields ######################################################################## fieldName = "FACILITYID" aliasName = "Facility ID" fieldType = "TEXT" fieldLength = 20 ######################################################################## # Iterate over classes ######################################################################## print("Add FACILITYID to classes") classNames = ["cwFieldRestraint", "cwFitting", "cwPipe","AbandonedCurbBox","AbandonedWaterFitting",\ "AbandonedWaterMain","AbandonedWaterService",\ "AbandonedUGSecondary","AnchorGuy","BusBar","FaultCurrentZoneLimit",\ "FixedConsService","XY","PriOHElectricLineSegment","SecOHElectricLineSegment",\ "SecUGElectricLineSegment","ServicePoint","SpanGuy","Streetlight","Substation",\ "Transformer","TransmissionLine",\ "wCasing","wFitting","wCurbBox","wFieldRestraint","wMainTap","wMaintenanceTap",\ "wOffset","wPumpOut","wRawCasing","wRawFitting","wRawMain","wServicePoint",\ "wSludgeCasing","wSludgeFitting","wSludgeMain","wMain","wMeter","wService"] for c in classNames: if (not FieldExist(c, fieldName)): arcpy.AddField_management(c, fieldName, fieldType, "", "", fieldLength, aliasName, "NULLABLE") else: print "Field " + fieldName + " already exists in class " + c print("Fields added successfully") print("Process completed") except: #If an error occurs when running Addfield, print out the error message. print(arcpy.GetMessages())

Ted - Have to add an additional point to this thread. What I had hoped to do was add a line geometry field to what was otherwise a point feature class. I find when I do this the class shape type also gets changed from point to line... which is not what I hoped. Anyway, am reverting to your method of the text WKT field, which seems to be working OK so far. Thanks much! Ed

‎12-28-2017

Ted - Thanks much for the suggestion. As I looked back further into the code I was using to add the geometry field I realized I wasn't setting a geometry definition for the new geometry field I was trying to add. Once I created a new geometry def and assigned it to the new geometry field I was able to add the field without error. (code below) Thanks again for your suggestion. I'm sure that would work as well. Ed

Am trying to add a second Geometry column to a feature class. I know Arc applications won't know about this field -- and I would not want them to -- but the field would be added to support custom functionality. The basic process of creating a field of Field Type Geometry and adding it to the feature class just fails. Have tried adding a blob field and storing a Geometry into it errors as well, though I haven't gone very far down this path. I realize I could create another feature class with a relationship to the first, but want to avoid this if possible. Any pointers on a preferred method that's been found to work would be much appreciated. Thanks, Ed

At this point I am 99% certain that my problem is that the query is operating on a runtime feature table that contains polylines with parametric curves. When I use the same query on point features I do not see the problem. Any given the fact that when using the query on polylines the issue was sporadic and unpredictable makes me think curves were the issue. Unfortunate that runtime doesn't support these things... or at least provides a clearer error when they're present. Ed
