You need to install Oracle Express Edition (XE) and set it up to run on your computer, on port 1521 - for your connection to work.
SQL Developer is just a client - there's no database there, unless you've put it there.
You need to have a running database to use with SQL Developer. If you haven't installed it yet follow the official documentation . If you do have the database but can't connect to it, make sure that
localhost
) Apart the suggestions of @Nikita and @thatjeffsmith, I highly suspect the matter is that you are using the pre-existing user hr
that you didn't create by yourself but that was created during installing your Oracle Express instance.
This user is by default locked . It must be unlocked by an administrator (for example SYSTEM
user).
After unlocking hr user, don't forget to grant to it CONNECT
and RESOURCE
roles. Find more details on this page.
