Architecture

Hello there FME community! I am working as an external consult with the GIS-team at a company where I have a shared responsibility of the FME environment. We are managing about 200 workspaces, each running more or less every day on Flow moving data around and generating reports.Every second year we upgrade the FME instances, setting up new virtual machines for FME Form, installing new FME Flow instances and upgrading all the workspaces. This takes a long time, as we have to open all workspaces, save them in the new version and then test that they behave like before. While this works for us and the customer is pleased, I really believe that the process could be more efficient. Are you in a similar situation? How are you approaching the upgrade? Are you upgrading the FME environment in a similar way, or do you have a more efficient approach?  Best regards,Jacques de Flon

We are running 4 FME Flow 2025.1.2 environments (DTAP) and 1 FME Flow 2025.1.3 lab environment, all in a fault-tolerant setup with 2 cores and 2 engine hosts.In our DTAP environments, we initially had an incorrect configuration:processmonitorcoreconfig contained localhost instead of FQDNs for both cores Each engine host was registered to a different core (processmonitorengineconfig)This resulted in jobs mostly being picked up by a single engine host, depending on which core was leading.In our lab environment, the setup is correct:FQDNs are used Both engine hosts are registered to a single core Fault tolerance works as expected (both engines process jobs, and failover between cores works correctly)We applied the same configuration changes to DTAP to match the lab setup. However, after registering both engine hosts to a single core, we observe the following

Hello FME community!I am using FME Flow 2025.2.4 Build 25835 - win64 and I am having issues with connections in apps and galleries. I have created Roles, shared my connections with full access, created new connections per this article http://fme.ly/zn8 nothing seems to work. The funny thing is that it has nt failed for me is I run the workspace directly in FME Server.Are there any tricks that I have not tired or is this a bug?Thank you in advanced for any help/ideas that you can provide. 

Hello,FME Flow requires ArcGIS Server to allow for direct access to geodatabases and ArcGIS Server is licensed per 4 physical cores.As such, if you have an FME Flow deployment machine with 8 physical cores, will this mean 2 ArcGIS Server licenses?From and Esri perspective, I would say yes (I work for Esri Australia) but wondering if Safe Software know of any arrangement, given that ArcGIS Server does none of the processing, just providing the libraries.Mark

I’ve noticed a few issues since upgrading FME Form & Flow (FME Flow 2026.1 Build 26103 - win64) that seem to show up when I’m also developing in FME Form while remoted into our FME test VM.This is how I usually work, mainly because some jobs take a while to run and if I do them locally my PC can go to sleep after 5 minutes and the jobs fail. This setup has never had an issue in the past. Since the upgrade though, running Form this way can cause problems with FME Flow on the same VM. When I’m running heavier workbenches and CPU hits 100%, Flow can become unresponsive or look like it’s soft‑locked. This never happened before the upgrade.One thing I’ve noticed is that this seems to mostly affect SSO sessions. My theory is that when CPU is maxed out, Flow struggles to grab required info for SSO before it expires. Just a guess.

After upgrading from FME Flow 2024.2.3 to 2025.2.4, the labels (titles) under Gallery Apps are now rendered as blue, underlined hyperlinks.Previously, the labels were displayed as plain black text without underline, even though the entire app tile was clickable.2025.2.4:2024.2.3:Are there any built-in configuration options or recommended approaches to control the styling of Gallery App labels? We are aware that other organizations have experienced the same issue after upgrading from the same versions.

Most REST API’s I have worked with work in a similar way with regards to authorization: Based on some credentials, you generate a token, and use that token for subsequent requests. You can usually create as many tokens as you want using the same request. What I noticed in FME (but please correct me if I’m wrong), is that a token must have a unique name, and when using the same request, you get a response that says Specified user token already exists. Of course I can update an existing token, or delete it and create a new one, but that means that in most cases, I need two requests instead of one.Another thing I noticed is that expired tokens are not deleted automatically: A request to /fmeapiv4/tokens showed me a token that apparently I generated 7 years ago! I am curious about the reasoning behind this way of using tokens. I mean, why does a token have to have a name, and why would you keep generated tokens forever?

Hello,I am trying to run a workspace using FMEFlowJobSubmitter to our FME Flow server, but the job submission fails.The log shows the following error:This workflow was working with our previous installation using FME Flow 2023, but since our new installation the job submission fails.Does anyone know what could cause this error?Thank you.

Hi have a flow which takes in data from a secure file transfer protocol, processes the data and produces two CSV files.  Currently these files are written to a local drive.  How can they be saved to the FME server so that they can be used in other workflows during a particular session and then deleted afterward?  Im guessing a flow parameter needs to be created and then pointed to by the writer but I really cant figure this out exactly

As I understand things, currently one can only use the Esri enterprise geodatabase formats on a Windows host. When moving to kubernetes it is then needed to use queue control to direct those jobs to Windows VMs, which is not ideal.When can we expect those drivers to also work on Linux? And is the problem on the Esri side or the Safe Software side?

So not specifically about FME, but very useful nonetheless:https://thecodingkitty.com/videosShort videos explaining IT concepts, with cats 😺. A lot of them are quite relevant to FME Flow.

If someone chooses to use FME Flow for Connection Storage in FME Form, how does it work when the FME Flow connection is changed from one environment to another?Do the connections automatically switch to those defined in the second environment, or does the Connection Storage need to be updated each time?Will the Deployment Parameters follow the change?

Hi everybody, Our BackupConfiguration.fmw has been failing lately. Based on the following post, I created new schedule on Flow but still having issues.  With the new schedule, I am having the attached error. However, gisadmin does have a fmesuperuser role. Any insights is highly appreciated.  Thanks in advance!

I got an error from FME 2019.2 and FME 2022.1. The error is " Python Exception <OSError>: Could not find a suitable TLS CA certificate bundle, invalid path: C:\\Program Files\\PostgreSQL\\15\\ssl\\certs\\ca-bundle.crt".Anyone has idea how to fix?

 I am trying to make a custom top level resource folder work, but i can't write the output of my apps and workspaces to the folder.  If i try to write output to the custom folder, it fails almost immediately, and when i inspect the logfile it just says Log Error The log file for job ID "816" does not exist.Did i forget some steps in the configuration of the custom folder? Or what did i do wrong? Thanks in advance for the help!  For reference what i did:Adding Top-level resource folder in FME Flow | Community

 I want to ensure that the Job logs are retained for 521 weeks and do not get deleted during the system cleanup. As a result, I have configured as per the screenshot in the above image. Is the configuration accurate? 

Recently been working on a process that uses the sharepoint online connector (package 1.7.1) to download, list, upload and delete files.This is working as expected in FME Form (tested on both 2024.1 and 2025.1)However, when this is deployed to FME Flow 2025.1 the sharepoint online connector that should download a file returns an error (but doesn’t cause the workspace to fail)Error: SharepointOnlineConnector: Could not connect to server. Check that you are connected to the internet and that no firewall is blocking outbound connections.(Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self-signed certificate in certificate chain (_ssl.c:1028)')))'The workspace continues and the sharepoint online connectors that are listing and uploading items work as expected.It’s been tested on another similar FME Flow environment that has not yet been upgraded to FME 2025 and the erro

I would like to add the following folder, named "moi”, to my top level resource folders, and add it to the list in the picture below. I couldnt find that much information about it online, and i tried something, but it didnt work. I located the folder in the FME Flow program files, and added the folder, but that didnt work. It doesnt show up in the top level resources list, Does anyone know if it is possible to do this? And how?  Thanks in advance!  

Hi,Our department currently uses 2025.1.1 version of Flow.Is there a way in FME Flow to identify the database/web connections used by workspaces/workflows without the need to go into automations or schedules to identify them manually? Ideally, it would be great if can create a dashboard that lists all workflows (across all workspaces) along with the database connections they use. The reason for this request is that multiple offices within our department use FME Flow and have uploaded their own workflows. As a result, we’ve discovered that duplicate database connections have been created by these different teams.Currently, I have to manually inspect each automation or schedule to identify the workflows and their associated connections. A centralized dashboard would greatly simplify this process and help us enforce standards by identifying and eliminating duplicate database connections.Any help or ideas is much appreciated!Thank you,LS.

Hi, I have installed FME Desktop onLinux (Technical Preview), unforunatelly when I try to start Workbench I get the following message: Segmentation fault Did anyone of you have similar problem, is it something wrong with Linux configuration? fmedatainspector seems to work fine.

Hi everyone, I was wondering if there’s a smart way to check whether any of the transformers in my uploaded workspaces (on FME Flow) are out of date or could be upgraded. Right now, the only method I know is to download each workspace one by one, open it in FME Form, run the upgrade process, and then re-publish it back to Flow. That feels quite time-consuming when you have many workspaces. Is there a built-in feature, script, or workaround that can help identify which workspaces contain upgradable transformers without having to go through them individually? Thanks in advance for any tips!

Hi.I just did an engine upgrade of my 2024.0.1 Flow instance to the very latest version 2024.2.1I then created a workspace in Form version 2024.2.0, and tried to upload it to Flow to test deployment parameters.But I get a warning stating, that Flow is older than Form, and the workspace is unrunnable on Flow.This is not good, as an engine upgrade is a nice way to keep Flow running with the latest version without the hazzle of major downtime and reinstallation.Why can’t the Flow 2024 UI handle engine upgrades, and why is my workspace blocked on Flow ? 

Hi, I have observed when the workspace is executed through the FME Form, the log file is generated into the folder path mentioned under the Logging>Log File parameter.  However when the same workspace is published on FME flow and executed through the workspace app, it does not generate the log file in the folder path. The user can only download it through the FME flow under jobs
