Validate Network Topology Error

LindseyStone

When validating my network topology on dirty areas it fails with a very generic error message. I tried it through the GP tool and get

and if I just try it the data tab across the top of Pro I get either one of these.

I just created this Utility network and getting this from the begining. I am getting this message in default and in child version. I'm running Pro 2.6.3 and Server 10.8.1

I had some issues in 10.8.1(and before as well) with "Validate Network Topology" tool. The errors were generic errors like "ERROR: General function failure","ERROR", "ERROR:FDO" etc. However, recent patch UN Patch 4 for v10.8.1 seem to have fixed these issues and has improved the speed of the validation as well. I also see CPU or RAM is stable during the validation and not hitting the roof. Thanks to the team who worked on this patch 👏.

I have had topology issues since I have started the utility networks, however it wasn't until we moved to 10.8 that I found our topology was unable to work at all. Now that I have disabled and reenabled topology (which clears the current topo) I have still had issues with it, but not so much it can't be deleted entirely.

Just for an update. I exported my asset package and set up completely new SDE geodatabase, service and all and it working. ESRI still can't tell me what went wrong in the process of the creation the first. But it is now working.

Since others is also having issue I'm curious to know if their validating issues started happening immediately after creating the geodatabase and service or if was working and then eventually broke.

I have discovered how to solve this bug VishApte! First I had to change ownership of the portal owner of the dataset using the Update Portal Dataset Owner tool. You may not have to do this but we went from one generic account login to named user accounts on the new update and my user was not the Portal owner of the data set.

Next, I Disabled Network Topology. You will need an exclusive schema lock for this process. Then you Enable Network Topology. What we just did here cleared out the entirety of the dirty areas and gives you a fresh topology to begin.

From here I was able to validate new topology (as I mentioned in my last post) as expected.

I hope this helps!

I may start a new thread for this since it has been marked solved, but is not actually solved. I will update my response after the patch is installed later today.

We are installing the UN Patch 1 this afternoon so I won't know if it helped until then. What I do know is that I was able to create and validate NEW topology. Dirty features that were present before the upgrade cannot be validated. However, this only appears to be in one of our services. Another of other utility networks is able to validate, making me think it's a specific type of dirty feature or, in our case, a line error causing the dirty feature to get stuck.

The oddest thing about this is that in 2 out of the 3 Utility Networks I maintain, we cannot clear topology. One of the networks is a backup network I created just to create network diagrams as topology validation has caused us many slowdowns in the past. This one currently has zero total features. Not a single one, and yet I still cannot validate topology.

Update: Installed ArcGIS Pro 2.6.3 patch and Enable Topology worked. But Validate Topology still fails consistently with ArcGIS Enterprise 10.8.1 UN Patch 1.

And I get this error sometimes

Has anyone found a right combination of patches?

I recently upgraded my ArcGIS Pro to 2.6.2 and ArcGIS Enterprise to 10.8.1 and I am now having exact same issue as @LindseyStone . Any edits or creates and I cannot run validation after using tool or Pro command. I tried to install 10.8.1 Patch 1 for UN. But after this patch, I consistently get error Enabling Topology as below. I have tried machine reboot, ArcGIS Enterprise restart etc.

Anyone found working ArcGIS Pro 2.6.x, ArcGIS Enterprise 10.8.1 and UN 4?

LindseyStone

So installing Pro 2.7 did not fix this issue, it is actually every time instead of getting a few validates before erroring out. I haven't installed Patch 2 yet, didn't know there was one, but the description is about reconcile and nothing about validation.

Hi,

You can get all the patches available to ArcGis Server going to the machine running it, click the windows icon and go to the ArcGis folder. There you will find an application (Check for ArcGis Enterprise Updates) that lists all the patches available for your version of ArcGis Server/Enterprise.

On 12/29/2020, Esri released a second patch for ArcGis Server 10.8.1 Utility Network. Check the pictures below.

JasonVignochi

Nevermind, figured out the release for patch 2 was pulled back. We are about to install the first patch and see if this rectifies the situation.

JasonVignochi

Where can I find this patch at? I have been searching all over for it and can't seem to find it. I am having this same issue right now and it's extremely problematic for my org as we need the network diagrams and we cannot clear topology at the moment. We just switched to 10.8.1 a few days ago.

Billy

Hi,

Could you post the URL for the bug again. It's broken.

VishApte

I get little confused when the Esri says patch to ArcGIS Pro is required for UN related issue. All ArcGIS Pro is doing is calling a GP service that is a wrapper to UN REST API e.g. Validate Subnetwork REST API.

Using Fiddler, you can trace the REST API call and parameters that Pro uses. Then call this REST API directly using browser with the same parameters. If it still fails, the problem is likely to be in ArcGIS Server or the UN dataset and not ArcGIS Pro.

LindseyStone

I have that patch applied. ESRI support says it is because of this bug https://support.esri.com/en/bugs/nimbus/QlVHLTAwMDEzMzE4NQ== and says it will be fixed with Pro 2.7. So now I'm in a waiting game to see if 2.7 actually fixes.

Billy

Hi,

I was having similar problems when validating the topology. In my case, the problems came from a missing patch for Arcgis Server 10.8.1 that it's necessary for the UN to work properly. Make you that you have this patch installed.

It would be helpful if you could capture the ArcGIS Server logs at the time of the validate failure to see what specific error is returned. It may even be good to get your data inhouse so our development team can test against your data. I am not sure if that is a possibility, but please let the analyst you are working with know if this is possible.

It does sound similiar, but without getting a closer look at the logs we won't know for sure what the cause in the validate failing.

At first it was validating some times, but once it started to error it would error every time. The only way to get the error to stop is to disable topology and then enable topology. But it is very short lived before it starts again. I have ran the GP tool, the validate in the ribbon, and opened up a completely blank project.

I did finally find this bug that is pretty much spot on. Bug BUG-000133185

MelissaJarman

I read through some of your notes where you said,

"It seems if I give it a minute or two and try it again it will validate successfully. However, I haven't done tons of edits to this data yet, due to the fact that I was getting so many validation errors yesterday."

So the validate will succeed sometimes? Sounds like you may be experiencing timeouts. Have you tried using smaller extents? The geoprocessing tool uses asynchronous processing which uses a separate service with a different timeout setting than the feature service itself. You can modify the timeout for this service to be higher if needed.

I have had similar problems with Validate Network Topology command previously.

Here is what I normally do.

1. Use GP tool instead and use small extent where dirty area is instead of full service area.

2. Create a new map. Add UN topology layer to it and accept to add all layers that participate in UN. Then run validate topology command or tool.

3. Check ArcGIS Server logs when error happens. It may indicate the problem. You may decrease log level to Debug or Verbose for diagnosis.

Hope it helps.

I did put a support ticket in on November 18th, but they have been so busy switching people on me who can't help and taking over 24 hours to respond to any message. I'm making it no where because they evidentially didn't pass the information on from the previous person. So they had to ask all the same questions again. I have yet to get to any actually troubleshooting.

MelissaJarman

@LindseyStone - You should not be getting a generic validate failed error message like this.

I would recommend contacting support services to see if they can help isolate the issue further and either log a new data specific bug or link you to an existing issue.
