Geoprocessing Service using Model Builder Iterators?

HeatherLizama

Hi,

Currently I have a model that works on desktop but does not run as a service. I have narrowed down the issue to a failure of the tool, "Iterate Field Values" that is available in model builder.

Is it even possible to use the iterator tools (available in Model Builder - ArcGIS 10) and have it run as a service? Or should I have only python scripts that complete the iterations?

Thank you for your help! H

Would the above error have anything to do with the size of the Input Parcel Parameter FC? The FC has approx 300,000 records.

Thank you!

HeatherLizama

Thanks for all of the helpful info. I have updated, I think, everything that you have mentioned.

Getting the following error after running the service:

updateParameters Execution Error: Runtime error <type 'exceptions.ImportError'>: No module named collections
Failed.

Thoughts?

I made some changes to your model and it worked from ArcGIS Server 10 .NET.

1. Removed the delete in_memory at end of model
2. Remove in_memory from layer names
3. Changed the 2nd parameter in your zip script from required to derived
4. Dropped the custom save location, the server's scratch workspace should be used. The model will now return a zip file and that file can be used in the second step of your tool.

Some other things to consider when publishing:
1. Do the SOM and SOC accounts have the proper permissions to run this task?
2. Is all the required data accessible by the SOC?
3. Enable local jobs directory
4. Turn on show messages when debugging online gp tools

Model1a_new.zip

The model has been updated with all necessary tools.

Input Parameters:

1) Boundary Feature Set with one or more polygons
2) Parcel Feature Set with numerous polys within Boundary Feature Set
3) Folder string to pass to "Zip Folder" script

Output Parameters:

1) Zip file of parsed out Parcel polygon Feature Classes

This service will pass a zipped folder to another service to complete statistical analysis.

This service gives no errors after publishing and no descriptive errors at run time...just states "Failed".

Thank you for your help!

Ok, how about just posting the model and script source code and describe what type of data you are using as inputs. Points, lines, polygons, etc...

Thank you

HeatherLizama

Cannot post the data online due to non disclosure agreement. But if you could message me privately or I can set up a GoTo Meeting? How do we connect for some help? Thanks, H

AndrewChapkowski

Can you post your model with sample data?

Thanks

Hi Andrew,

I initiated and tested the zip tool. See attached model. It works well on desktop and it did publish to a service without errors. Can you or anyone else see why this service is failing?

Info about model:

Enter a Graphical Boundary or a Boundary Feature Class: Data Type - Feature Set

Sel_Bound: Managed - in_memory\Sel_Bound

Bound_Lyr: in_memory\Bound_Lyr_%Model_Value%

Parcel: %scratchworkspace%\Scratch.gdb\Output\Parcel_%Model_Value%

InputFolderString: \\\GEOSERVER1\ServerData\Model1a\Scratch (it crashes on desktop without the extra \ ) Data Type - String

Calculate Value: Expression - "%InputFolderString%", Data type - Folder

Zip Folder script - Input Data Type: Any Value, Output Data Type: file

Enter the location to place the Output Zip File (must be named *.zip): %scratchworkspace%\scratch.zip

Thanks!

Since I have other iterators (ie/ iterate feature class), I cannot put the models into one process. Yes, python is an option, but the models are already built. It would take a lot more work to get this running in python.

Thanks for all of your help! I will give the zipping option a try.

AndrewChapkowski

Like I said, multiple output feature classes are not supported right now.
Can you combine your whole process into a single model without using sub-models? Maybe you should consider using a python script instead of doing a pure model builder process.

HeatherLizama

Hi Andrew,
That is great to know that model iterators will work in a service.

The model that I posted is only a portion of the total process. I learned through testing that submodels would not work properly in a service, so I have split the whole process into three GP services that will be called by Flex to run consecutively. The final output is tabular statistics.

Adding the zip option to the end of each model, then unzipping for the next model, would add run time. Is there no other way to have multiple feature set/feature class output?

AndrewChapkowski

Iterate value worked for my published model, I think your problem stems from the return type. It looks like you are trying to return each feature class, which isn't supported at this time. In short, Multi-feature outputs aren't supported yet. I would suggest returning a zip file to the end user of your extracted data.

HeatherLizama

Thank you Andrew for your reply.

Yes, I have gone through the services checklist quite a few times in the testing process.

Yes, I am also using %scratchworkspace% for output parameters.

Are model iterators possible in a service? Thanks!

AndrewChapkowski

Did you follow all the guidelines found here: http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/Checklist_for_authoring_and_publishing_geoprocessing_services/002v0000000w000000/

Are all results being written to %ScratchWorkspace% or %ScratchWorkspace%\scratch.gdb ?

HeatherLizama

Please see the attached image of a portion of my model that does work on desktop but does not work as a service. Any suggestions would be appreciated!
