Connection using sqlplus / as sysdba works as expected, however connect sys/<passwd>_at_tns as sysdba just hangs. No error reported. I didn't have time to investigate today because the client's office was closing at 5PM. Does anybody have a pointer about the possible cause? I have never seen that, it looks like a bug. If anyone has a pointer, I'd be much obliged.
