While this isn't an eloquent solution, we switched from using the Connection Type 'TNSNames' to BASIC (and then manually supplied the hostname/port/&SID ==> all available via a tnsPing or just looking at the tnsnames.ora file) and it worked. While I would have liked to fix it, getting his developer worker was more the pressing concern and we left it at that. hth –Harrison Aug 11 '11 at 11:34 add a comment| 10 Answers 10 active oldest votes up vote 6 down vote http

Oracle Network Adapter could not establish the connection tips http://www.orafaq.com/forum/t/179711/ Oracle Database Tips by Burleson Consulting October 29, 2015 Question: I am trying to install SQL Developer and when I try to open the forst screen and connect sql developer I get this network adapter error: java.sql.SQLException: Io exception: The Network Adapter could not establish the connection. How do I resolve this Network Adapter could not establish the connection error? Answer: Whenever you see a Network Adapter could not establish the connection, you have either the wrong SQL Developer URL or you have a basic SQL*Net connectivity network adapter could issue! This error is most likely caused by one of these factors: - You are using the wrong URL- The wrong port number or IP address (or DNS host name) was used- The listener is not configured properly- The listener process (service) is not running. You can re-start it with the "lsnrctl start" command or on Windows by starting the listener service. For a step by step checklist, see my notes on troubleshooting an Oracle connection problem.
