I'm a student and need to practice Oracle SQL queries since we have Advance SQL in our syllabus. I have Intel-based MacBook Pro running Mac OS X Snow Leopard 10.6.8. I just downloaded the SQLDeveloper for Mac and unzipped it. The application executed and started well. But I'm not able to create any connections. I get the following error:
Status: Failure -Test Failed:IO Error: The network adapter could not establish the connection.
When I key in the following parameters:
Password: hr
Connection type: Basic
Role: default
Hostname: localhost
Am I doing anything wrong? Do I need to install anything else? I'm newbie so please co-operate with me if I have ignored anything. I also Googled this error, found lot of search results but couldn't solve my problem. Any help would be highly appreciated.
Have you installed dataBase first. i think you need to install db and then try to establish connection using sqlDeveloper.i too have same problem
