The Role Manager can be reached via the Enterprise Manager. Double clicking the Roles node will open up a window similar to this one:
The Oracle Role Manager
A list of all roles will be displayed, if the role requires a password, this should be displayed.
When editing or creating a new role, use the OK button to save your changes and the Cancel button to, well, cancel your changes.

For further information regarding authentication methods, see the Oracle documentation.
Create New Role dialog, page 2
On the second page, Roles, you can assign the new role to existing roles by checking the check box in the Granted column. By checking the Admin-column check box, you can give the role the rights to grant the given role to other roles.

The buttons in the toolbar are shortcuts to grant everything to the role or revoke all given privileges.

Editing a role will show the same dialog as creating a new role and all properties can be modified except the role name. Modify the role to your liking and use the OK button to save your changes to the database.
By using the Drop Role button you can delete a role from the database. Any privileges inherited from this role by other roles or users will be removed.
