Hi guys, 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:
Connection name: hr
Connection type: Basic
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. Thanks!
