@Jörg Burdorf I ran into what looks like the same issue. I was able to provide the development team with a sample system that was showing the behavior your described. It turns out that the Db2 Data Management Console gets confused if the Repository Database isn't available when the Console is starting up. I suspect that may be the issue your have encountered. If you restart the console all your connections should reappear.
In my particular system, I run the Db2 Repository database and the Data Management Console on the same Linux machine. Both are automatically started using SYSTEMCTL. When Db2 is installed, the db2fmcd.service is installed. This watchdog service makes sure that Db2 starts up and restarts in the case of a crash. However this means that Db2 starts up slower than the Console.
To solve this, I put a 2 minute time delay in the auto start service for the Console and everything seems to work fine now.
The development team is adding better messages to help identify this issue in the next update and looking for the best way to make the console more resilient to disruptions in access to the Repository database in the following release.
When I get a minute, I will post an example of how to automatically startup the Data Management Console as a Linux service. Let us know if this helps!
