Your 10g XE server comes with a sample database user account called HR. But this account is locked. You must unlock it before you can use it:

* Log into the server home page as SYSTEM.

* Click the Administration icon, and then click Database Users.

* Click the HR schema icon to display the user information for HR.

* Enter a new password (hr) for HR, and change the status to Unlocked.

* Click Alter User to save the changes.

Now user account HR is ready to use.
