What Message Level do you have the GP service set to? If it is set to Info, the client should get all of the messages and errors back from the job.

Although I am not a fan of the Python Requests library, I will second @EricEagle 's comment that support for PKCS#12 in general is very important. It doesn't matter how good software is today in the enterprise if it doesn't have robust support for a range of authentication and access mechanisms.

The CIMVectorLayers are undocumented, at least from the ArcPy perspective. One can consult the ArcGIS Pro SDK documentation to read about that part of the CIM model, so I don't consider CIMVectorLayers completed undocumented. And, I have definitely used completely undocumented portions of ArcPy and other Esri APIs, so I support people sharing such solutions as long as they note the undocumented aspect of the solution. I initially marked this response as a solution; however, I found using CIMVectorLayers quite buggy when testing the approach. The behaviors were inconsistent enough that I unmark it.

Regarding the first question of this post, i.e., are spatial definition queries SQL based, I think comments in this post and Spatial Definition Query — Copy parameters as text to clipboard correctly infer the answer is "no, spatial definition queries are not implemented using SQL." Often times when diving into the weeds with questions like this, it is helpful to research the ArcGIS Pro SDK | Documentation. Looking at the DefinitionQuery Class - ArcGIS Pro, there is a GeometryUri Property (DefinitionQuery) - ArcGIS Pro: Gets the geometry uri to filter rows in the dataset. What one doesn't see when looking at the DefinitionQuery Class documentation is any property or method that would indicate the type of spatial operation to apply to the geometry obtained from the GeometryUri. Those missing properties or methods strongly indicate there is only one way the geometry is handled, and that is intersection at this point. What one also doesn't see in the documentation is what format is used for storing the information at the GeometryUri. Usually the property or methods for interacting with stored geometry will be include part of the format name, like "FromWKT." It turns out the geometry at the GeometryUri is binary, which was unexpected for me. Looking at the binary format, I am fairly certain it is Esri shape formatted binary byte buffer, essentially the same format used for shape files.

I would argue the final comment is misleading. Although the new layer is based on the data source of the original layer, and the new layer inherits symbology from the existing layer, there is no relationship between the two layers after that point. For example, if the symbology of the original layer is changed, the previously inherited symbology of the new layer does not. Also, if different records are selected from the original layer, it does not change the records that make up the new layer.

ArcObjects? I understand what is meant, but I do think it is important to point out for readers that ArcObjects has nothing to do with ArcGIS Pro. From ArcObjects Help for .NET developers (ArcObjects .NET 10.8 SDK): ArcObjects is a library of Component Object Model (COM) components that make up the foundation of ArcGIS.... ... ArcGIS Desktop is a suite of integrated applications including ArcMap, ArcGlobe, ArcScene, and ArcCatalog. The original ArcGIS Desktop applications, i.e. ArcMap, ArcCatalog, etc..., were built on top of Microsoft Component Object Model (COM) while ArcGIS Pro is built on top of Microsoft .NET platform. Although there is an ArcObjects .NET SDK, that SDK is a effectively just a wrapper to help .NET developers interact with COM objects. What term should be used instead of "ArcObjects?" Should we say ".NET", or go with something more generic like "native code" or "compiled code?" I don't know if there is a clear winner, but I think it best to avoid using "ArcObjects."

The spatial component of a definition query cannot be easily copied, or maybe copied at all, to the clipboard because it is stored as binary data. Also, depending on what kinds of geometries are used, the size of that binary data could be quite large.

Although having insufficient paging space can cause memory issues, so too can having too little physical RAM. The page file and physical RAM work together, and neither one can be a complete substitute for the other. (I am dismissing the old "I have so much RAM I disabled my page file" argument because that is a terrible idea for many reasons, especially in production server environments.) There is a limit to how much of a process address space can be paged, i.e., some portion of the process address space always has to remain in physical memory. Therefore, someone can have a 10 TB page file and still crash an application or system due to too little physical memory.

Thanks for sharing what you found. It used to just be antivirus software that could cause issues, but the breadth and depth of security software has exploded over the past decade, especially in corporate environments. Often times the big-brother software impacts performance, but occasionally it can break functionality as well.

Although those URLs can be called externally by end-users, they are used extensively by various ArcGIS Enterprise components in any deployment. ArcGIS Enterprise isn't a piece of software, it is a system made up of many pieces of software, and those pieces are constantly communicating with each other. I doubt what you are seeing is abnormal, but if you have concerns then open an Esri Support case.

I have never come across any documentation related to this subject, but I can't say I would expect to either. Part of the trouble with sharing information related to this topic is the number of variables/factors involved. It isn't as simple as "ArcSOC processes use 40% more virtual address space." We saw some services use nearly the same, although probably 90% used noticeably more, but even then some were 10% more and others were 60% more. The average probably came out to be around 25%-30%. Even without changes in software versions, changes in service configurations or service usage can significantly change memory utilization on the server. The expectation should never be, set-it-and-forget-it. Just like any other enterprise IT application, the OS and application should be constantly monitored to determine if resource or configuration changes are needed.

Without knowing more specifics about how ArcGIS Enterprise is deployed, it is hard for community members to provide feedback. For example, are you running ArcGIS Enterprise on-premises or in the cloud? If in the cloud, did you deploy it using one of Esri's tools or deploy it yourself? Are all the components on the same machine or do you have separate machines for each component? Are you running High Availability portal? Are you running multiple-machine ArcGIS Server sites? Etc..... ArcGIS Enterprise isn't a piece of software but a system made up of many pieces of software, and how those individual pieces are deployed can very much influence troubleshooting.

This issue has been discussed on Esri Community: Why is there now multiple files per install of ArcGIS Enterprise Components at 11.3? Also, the ArcGIS Enterprise installation documentation covers it (https://enterprise.arcgis.com/en/server/latest/install/windows/install-arcgis-server-on-one-machine.htm) As of ArcGIS Enterprise 11.3, the ArcGIS Server self-extracting package consists of two files with .exe and .exe.001 extensions. To extract the package, ensure that both files are in the same folder.

When discussing defects, it is helpful to provide the bug number. Most defects, although not all, are searchable through Esri Support website and can be linked to in forums/communities like this one.

Memory configurations are very specific to machines and applications, so it is hard to give recommendations without knowing quite a bit more information. While allowing the OS to wholly manage the virtual memory settings is convenient, and maybe sufficient for some groups/organizations given their situations, I doubt you see it being used in many enterprise IT operations. What I can say at this point is that ArcGIS Server 11.x uses more memory than ArcGIS Server 10.x given the exact same services and settings. Whether that increase requires more RAM or different virtual memory settings on a specific server depends on the amount of existing RAM and existing virtual memory settings. I would encourage your IT folks to monitor various memory counters over time, simply pulling up Task Manager and taking a look a few times during the day is not sufficient. A spike in traffic can cause a spin-up of more ArcSOC.exe processes which can lead to a momentary spike in memory usage. If the spike is high enough, it can cause lasting instability in the ArcGIS Server framework processes. Memory spikes can also be brief enough that casually looking at Task Manager throughout the day won't necessarily catch them.
