I'm migrating Oracle 10g to 11g and at some occasions NetCA fails with the following error:
"The information provided for this listener is currently in use by other software on this computer.
Listener start failed."
I'm executing NetCA in silent mode right after installing the Oracle 11 environment (oui) and before
running the upgrade tool (DBUA).
When I tried to run the NetCA tool through the UI, I got a message saying the port is not available,
even when I tried to change the port to many options other that the default.
