SQL Developer connection problem
773314May 17 2010 — edited Oct 6 2011Each time I try to make a new connection I get the following message: 'Io exception. The Network Adapter could not establish a connection.' No matter how I try to connect, it's always the same. As a noob, I suspect I may be missing something. I would appreciate very much if someone could help me to resolve this problem so that I can move on.
In anticipation, many thanks.
