Hi all,   I have an application 10.6.2 with the satabase source set to internal database. Now I switched it to External database, which is a Postgress 15. When deploying I, the checks ar ok, but at the moment Mendix tries to synchronize the Postgress database with my domain model configuration, the following error occurrs:     anyone an idea what is happening?    Thanks in advance, Jan

Hi Jan,

 

When your application has been upgraded with several versions, your database structure changes as well. When you upgrade several tines with the Built-in database being update and the external database not, you will face synchronization issues when you decide to change your database 3 Mendix updates later.

The best way is to delete your current external database that causes the error and create a new empty external database. Use this as your new database and Mendix will synchronize all the domain model configurations to your new external database.

Hi Jan,

 

When I get a M2EE error it is usually a different service or program already using the 8080 port. Disable the service or program using it, or you can change the port in App > Settings and edit the configuration.

 

In App explorer go to the app > settings then edit or create new configuration and on the server tab edit the runtime and admin port to 8081 and 8091.
