I need to backup my DB so I use Tools --> Database Export. However, when I want to choose my connection I got no connection in drop down list.
Just to mention that I can see my connection list in "Connections" tab and also all connections in "C:\Users{MyUser}\AppData\Roaming\SQL Developer\system3.0.04.34\o.jdeveloper.db.connection.11.1.1.4.37.59.31\connections.xml" file
Same behavior happens also in "Database Copy", "database Diff" and in "Monitor SQL"
Any idea ?
Thanks in advance
