Welcome to the forum!
Hello, I'm a beginner at Oracle SQL developer. I just downloaded the sql developer 3.2.20.09.87 one which includes zip file JDK. However it is not letting me connect. This is the error I'm getting.
failure- test failed: IO error: The network adapter could not establish the connection.
How do I fix it.
How would we know? That's about the same as saying 'help, my car won't start. why won't my car start?'. Maybe you didn't put it in park, maybe you didn't put the key in the ignition, maybe you dont' have any gas. How would we know?
You have to provide detailed information about
1. what you are doing
2. how you are doing it
3. any errors or messages you are getting.
All you did is provide #3.
What are you doing? What database and version are you trying to connect to? What connection parameters did you use?
1. what you are doing : I've downloaded : Oracle SQL Developer 3.2.2 (3.2.20.09.87)
Windows 32-bit - zip file includes the JDK1.6.0_35 Download 209 M
