Could go crazy and have X copies of the MGDB and then run traces in separate ones in sub processes. Just throwing out ideas.

I would not suggest doing this on the prod UN servers. Copy and Paste or recreate the UN in a MGDB via the asset package. If you are going to use Enterprise, you should parallelize the traces, and run maybe 8 concurrently.

The UN_# represents the Dataset ID of the Utility Network. This is defined when the database is created, as this represents the ObjectID of that item in the GDB Items table. This cannot change during enable/disable. Only if you delete/recreate the database. Are you sure you are connected to the correct service? Did you reload your data? Are you referring to the Layer ID of the Feature Service? If so, you should always assign a unique ID to them in your map prior to publishing.

You can model the pipe connections as devices. You do not have to use stormwater junctions. Can you provide a schema only UN and I can look into why the snapping is not working. Snapping is not enabled for Structure Junctions to Stormwater Pipes, as you cannot create a rule for this. You can always right click and select snap to though.

Can you fill in 0 for min and 1000 for max?

Two isolation traces are the only way that I know how to achieve this.

Do you have all the rules in a built UN? If so, I would just export the UN to an asset package, then copy the b_rules table from the exported asset package to the source asset package(deleting the b_rules table first). If not, you can use the rules matrix from the UDMS toolbox: https://github.com/Esri/Utility-Data-Management-Support-Tools https://esri.github.io/Utility-Data-Management-Support-Tools/docs/3.5/ExportUtilityNetworkMatrix.html

In hierarchical, it must be valid in the parent to be allowed to add to the child. Add it to System, then it will show as an option in the isolation.

Then you need to disable the Set Attributes from Z attribute rule. That is overriding your values with the Z of the line.

If you want to copy the Manhole elevation attribute to the Pipe, then I would look at the Spatial Join Templated Attribute rule. You should be able to configure it for your needs. https://www.esri.com/arcgis-blog/products/arcgis-pro/data-management/attribute-rules-generate-spatial-join

Edit, We do not have an Attribute Rule to set the Z's or attribute of the From/To elevation from the snapped feature. The rule you posted just calculates the slope of the line via the From/To Elevation. There is a rule to Set the From / To elevations from the Z. We rely on ArcGIS Pro and snapping to copy the Z to the geometry. How did you draw the sewer main? Was it snapped to the manhole on create? Did the manhole have a Z?

Are you using the pressure zone tier? If so, running your isolation trace on that tier could speed things up. How many controllers do you have on the system tier?

Would be interested in seeing the same batch trace run from a script, outside pro. 30 secs a trace is not good. Nothing batch trace can do about that. I think it is the gp tool overhead of running inside pro. You have 9 maps and one active. The trace is communicating with those maps. Try it in pro with no maps, you will see a huge improvement

I reviewed the code for Batch Trace and I take back this statement"Batch trace can use the resulting lines and remove them from the trace starting points to reduce the number traces required. " Batch trace does not have this skip logic, but Build Starting Points does. So you could run Build Starting Points and an Isolation trace to build out the starting points to trace the system. Then run Batch Trace with that reduced set. I will add an issue to expose that logic in Batch Trace too.

Also very interested in why Batch Trace is taking 15 seconds a feature. If you turn on debug mode, we can get a better idea of what is going on. Open ArcGIS Pro Open the UtilityDataManagementSupport toolbox Open any tool in the tool box. This loads the udms module from inside that toolbox into python/memory Open a python command prompt enter the follow: import udms udms.logger.setLevel('DEBUG') Run Batch Trace
