Hi,
I have some server side code which connects to the repository using a jvm connection/session. I have one thread opening
2 separate sessions with 2 separate transactions. When I commit one transaction the other transaction becomes inactive.
I do not want this (ofcourse..). Is there a specific setting I forgot to set or maybe something else?

That's not the expected behaviour of a transaction. Can you please add a LifecycleEventAdapter and dump the stack trace in onAboutToDeactivate()?

My fault, the threads shared a CDOSession and I called session.close in one of them. I guess that a CDOSession should
not be shared by threads?

To get different CDOSessions I need to create different SessionConfiguration instances?

:P

Sure, it can be shared. But the threads should be aware of that and not close it eagerly.

Yes, although that may change in the future.
