why didn't answer anybody? Is my question to stupid or to difficult? Has nobody out there the same problem?
I've tested now with 'autoCommit' = false on the Oracle JCA configuration. Now the db updates were not executed. Unless I'm shutdown the server. Then the connections to the db were closed and all the stuff is written to it.
Next try was 'commitOnClose' = false. But this changed nothing.
What can I do? Can please someone helps me?
