make a new connection with Oracle sql developer

Question

I know this question has been asked frequently. However, none of the answers from them worked for me. So, I am posting the question. I tried to make a new connection in sql developer using my Oracle account's username and password that I used while trying to download the oracle software. However, it gives me an IO Error whenever I use those details. I tried options like "system" in username and the password of Oracle account. However, it still is not working.

help would be appreciated.

Answer 1

Are you really trying to connect to a local database with your oracle ´s website account?

You need to get a valid username/password from the guy who has installed the database on your local computer

If it is you, then you provided a password for the « system » user during install

Edit :

How did I miss it! Your current issue is not about an invalid login/password if it was you would get an « invalid username » message.

The message you get is « could not establish connection ». This message means the database « orcl » is not accessible on localhost:1521.

You must:

• create the database orcl, if not already done

• configure a listener to make the database accessible
