@BrandonMcAlister, I see you posted Regular Expressions in Definition Queries .  Seeing that most data sources, including file geodatabases, already include support for regular expressions; did you figure out how to get this working? ... View more

This error message means exactly what is says, i.e., there is/was another administrative process running, and you cannot have more than one administrative process executing at the same time.  That said, orphaned lock files can cause ArcGIS Server to think an administrative process is still happening when it isn't.  Check the locks folder (if you have access to the arcgissystem folder), or you could also try restarting the machine. ...

I can't say it is the cause of your issue, but don't mix the field name wild card while also explicitly naming fields because it results in duplicate columns in the cursor. ... View more

Regarding page file size, where did you get or see that statement?  If a server needs a page file 3x the size of its RAM, I can guarantee any applications running on it are performing quite poorly. If you are not familiar already with the concepts and information in Introduction to the page file - Windows Client | Microsoft Learn and How to determine the appropriate page file size for 64-bit versions of Windows - Windows Client | Microsoft Learn, I encourage you to read both. A page file serves multiple purposes, and even with a given purpose, the use of a page file can vary greatly.  Most of the rules of thumb were created in the early days of the Windows NT operating system when machines had much smaller amount of physical RAM, and they are far from optimal for modern servers with large quantities of RAM. In the articles I linked to, Microsoft explains how the "system managed" page file settings generally work.  Unless you want to dive into process performance data to get a better understanding of how your applications are using memory, virtual and physical, it might be best to just let Microsoft manage it. As an example, the Windows 11 Professional workstation I primary use has 64 GB of RAM and currently the system-managed page file is 3 GB, that is 1/20th the size of physical RAM.  The page file will occasionally grow by tens of GBs when I start pushing RAM consumption, but it seldom goes above 30 GB, which is still 1/2 the physical RAM.  Could I provision a 128 GB or 192 GB page file manually?  Sure, but why waste 128 GB of SSD storage on a page file that isn't used. ...

The SQL LIKE predicate is a form of pattern matching, but it is not regular expression pattern matching.  Although support for SQL LIKE is much more consistent across database platforms than regular expressions, there may be cases where it is implementation specific, so it is best to state what data source you are working with. UPDATE:  An update to the question indicates you are working with file geodatabase data. As I mentioned already, SQL LIKE is not regular expression, and regular expression patterns will not work with LIKE, especially since Esri does not support character-class wildcards with the file geodatabase implementation of LIKE. Although undocumented, Esri does support a fairly robust regular expression implementation in the file geodatabase with the SIMILAR TO predicate.  Oddly, they even kept the wildcard the same as LIKE even though actual regular expression uses different wildcards. ...

Can you explain where the server and desktop machines are located relative to the data sources behind the map?  Is the map connecting to file geodatabases, enterprise geodatabases, something else, all the above? ... View more

Does your field name have a period in it?  For example, it looks like the field name is "inspection.date", which will definitely cause issues since that would make for 010085: <value> is an invalid field name.—ArcGIS Pro | Documentation Field names should only contain characters a–z, 0–9, and underscores. Do not use spaces, hyphens, parentheses, brackets, and other special characters, such as $, %, and #. Avoid using field names that contain words that are typically considered reserved keywords. These are typically data, day, month, table, text, user, when, where, year, and zone. Note that each underlying DBMS can have its own set of reserved keywords.   ... View more

With Calculate Field, there is no way to ensure row order, truly ensure it.  So, doing order-dependent row operations is kludgy at best and generally error prone.  With cursors, you can specify an ORDER BY statement to ensure row order, or you can loop through a cursor twice using a dictionary to store and update values.  If someone else doesn't offer up some code, I will take a look in a day or so. ...

Why does it have to be Calculate Field?  This is much more straight-forward with cursors. ... View more

Instead of manually checking it and cleaning it up, just create a scheduled task on each ArcGIS Server machine that will delete all the temp files on some regular basis.  If a temp file is actively in use and has a lock, the file won't be deleted, but everything else will be. ... View more

There are no structural changes in the URLs of GIS services between ArcGIS 10.8.x and ArcGIS 11.3, that is an existing image service that is upgraded will have the same URL as before, and a republished image service with the same name will also have the same URL as before.  Is that what you are asking? ...

If it is the datetime field causing the issue, then share an example or two of the datetimes from the web service and save community members the effort of having to go retrieve it themselves to help you. Retrieving the JSON, it looks like the web service is returning datetime as a string in the following format:  "2024-08-21T13:08:33.583Z".  That looks to be an ISO8601 compliant time format string, but currently the Data Access cursors cannot parse it (I have logged a defect already).  So, you are going to have to manipulate the time string into a simpler format that can be parsed. ...

As Chris is trying to help you tease out, there are a variety of issues that may be occurring.  Instead of trying to troubleshoot what has happened over the past 18 months, why not clear out the temp folder and then start watching it more regularly.  That way, you will have a much better idea of what is happening on ArcGIS Server around the time a bunch of temp files are created and not cleaned up. ...

Are they using an Esri tool or software program to query?  I am guessing not since you mention having "to provide multiple solutions for them," so how exactly are these users interacting with the REST API? ... View more
