2 Unlocking the Sample User Account
To create your application, you need to log in as a database user. Oracle Database XE comes with a sample database user called HR. This user owns a number of database tables in a sample schema that can be used to create applications for a fictional Human Resources department. However, for security reasons, this user's account is locked. You need to unlock this account before you can build a sample application.
To unlock the sample user account:
1.
Make sure you are still logged on as the database administrator, as described in the previous section.
2.
Click the Administration icon, and then click Database Users.
3.
Click the HR schema icon to display the user information for HR.
