Sql Developer - Network Adapter could not establish the connection

709169Mar 12 2011 — edited Mar 12 2011
Hello All,

I have a nagging issue. I am using SQL Developer Version 2.1.1.64 Build MAIN-64.45. When I try to log into certain databases with connection type TNS. I get the following error:

"Status : Failure : Io esception: The Network Adapter could not establish the connection."

Even though TNS sees the Connection alias.

When I change to a Basic connection type and enter in the Host name, port, and SID I can connect. Also the issue does not affect all databases. Some I can connect to using TNS Connection type and others I have to use a basic connection type. Can anyone explain this?

Thanks
Rdizzy
