ArcGIS License manager has 2 daemon, Sever and vendor. I have always set the Server port to something in the range of 27000 - 27009 and opened up the servers firewall. I never remember having to set the vendor daemon port before. We recently moved to ArcGIS Pro and named users. We want to move our license server into a DMZ and open up port 27000 so users can use ArcGIS Pro while working remotely. Will we have to set the vendor daemon port and open up this port as well?

I'm trying to track down schema locks coming from map services. I have noticed that shared instances no longer have the check box to "lock database schema". The attached images shows this difference. However I have determined that the locks are coming from shared instances using the code below. Is there a way to tell shared instances to not lock schemas in the same way as you can with dedicated instances? The shared instance process ID doesn't tell me which map service is causing the lock. SELECT A.SERVER_ID, B.OWNER || '.'|| B.TABLE_NAME "TABLE", A.NODENAME, L.LOCK_TYPE FROM SDE.SDE_PROCESS_INFORMATION A, SDE.SDE_TABLE_REGISTRY B, SDE.SDE_TABLE_LOCKS L
WHERE A.SDE_ID = L.SDE_ID AND L.REGISTRATION_ID = B.REGISTRATION_ID
ORDER BY NODENAME, SERVER_ID;

We are prototyping our data model using the latest version of the fabric, Pro 2.9 equivalent. The existing control monuments are classed as first, second, third etc order points. (Sorry I'm more a developer than a surveyor so my terminology is off I know) A subtype sounds very reasonable. Will this allow us to do adjustments? We currently don't do true adjustment work and are very interested in this functionality.

My understanding is that control monuments should be loaded into the fabric_points feature class. Is this correct? If so then how are monuments distinguished from corner points? Looking at the fabric_points attributes I don't see how we would correlate monument confidence to the existing attributes for use in adjustments.

It would be great to see this implemented but only as an option and not automatic. I have cases where I don't want attribute rules copied as they would break the destination FC. If both "feature class to feature class" and "copy" bring in attribute rules then I will have to do post processing to remove them.

I want to add my support for this. As others have said, this is a bug not a feature and it needs to be addressed asap if ESRI is serious about getting people to move to Pro from ArcCatalog.

I'm trying to apply an attribute rule to an enterprise geodatabase feature class. I have a tree feature class that has both species (scientific) and common name attribute. I'm trying to automatically fill in the common name based on what species an editor enters. I have a lookup table, ENV_TREESPECIES_LUT, that lists the species name and common name. The general workflow I'm trying to achive is: If a new tree feature has a species value then search the ENV_TREESPECIES_LUT for that species and return the common name But no no matter what logic I've tried the attribute rule editor in Pro gives me an evaluation error on line 5 of this script below. It seems to the filter function. What is the correct way to filter on an feature attribute? I should mention that the code validates in the expression builder, the error is only thrown when I try to save the attribute rule. var cn = ""
var fspecies = $feature.Species
if(! isEmpty($feature.Species))
var LUT = FeatureSetByName( $datastore, "ENV_TREESPECIES_LUT", ["Species", "CommonName"], false)
var common_names = Filter(LUT, "Species = @fspecies")
var common_name = first(common_names)
if (! IsEmpty(common_name.CommonName))
cn = common_name.CommonName
return cn

I finally got this working by using the command prompt to install it. This first time used the command prompt it failed with the same "installer is no longer responding" error. The second time the command prompt install worked. The only difference was I added the parameter to set the install location. Instead of taking the default location I set the install location to c:\myportal and installing from the command prompt worked. 😕
