I followed the support article in order to connect to a AS400 using the JT400 driver. And after some firewall issues, it went quite smoothly. (https://support.inductiveautomation.com/index.php?/Knowledgebase/Article/View/120/0/connecting-to-ibm-as400-iseries-database)
The local IT prepared some tables for me to read, but apparently, whenever they want to change the schema of those tables, f.e. add a new column (which requires a full lock), they cannot execute it as apparently I have locked the file.
To release the lock, it’s not enought to just disable the database connection, I also need to restart the complete Ignition service.
I found some articles online about hard-closed and soft-closed cursors, about differences between row locks and table locks. But as I’m not managing the created cursors, I wonder if it’s possible to release the locks from my side.
Does anyone know how the locks can be released? Either from my side, or by a command on their side.
