SIMATIC WinCC Open Architecture Forum

I'm working on a 3.18 project with NGA and a PostgreSQL database. We have a redu system and are setting up PostgreSQL as a cluster.
I followed all the steps in the help file ( https://www.winccoa.com/documentation/W ... uster.html ). The main.py script runs perfectly fine. ( I even copied those 2 DLL's as mentioned as a solution in the Help file)

Unfortunately, the PgClusterMonitor service wont start. A popup message is shown:

"Windows could not start the PgClusterMonitor on Local Computer.
Error 1053: The service did not respond to the start or control request in a timely fashion"

I installed postgresSQL 3.11 and downloaded all the packages.

I tried this on our server but the same thing happens on my Windows 10 laptop.

Does anyone have any tips or ideas ? Any help would be greatly appreciated

I just downloaded Python 3.10.8 and again followed the steps in the help.
Now, the service works perfectly fine AND the database replication seems to work

So.... skip Python version 3.11 for now

Bit late, but for what its worth: had the same issue on python 3.13.

Had to run my Python package install offline and found out I had to add the setuptools package in order for it to work.
When running from the command line, windows_service.py debug should start the service, but for me it didnt. Executing pip uninstall servicemanager solved that (following a suggestion from some random google search result).
Still no luck on the service end until I made sure my service user had rights to some directories ('cluster monitor tool', pgdata folder).
After that, it runs from windows. Apparently it wants to write to the log.log file and my service user did not have ownership.
