<&|/l&>We need to know the name of the database RT will use and where to find it.  We also need to know the username and password of the user RT should use. RT can create the database and user for you, which is why we ask for the username and password of a user with DBA privileges.  During step 6 of the installation process we will use this information to create and initialize RT's database.</&>
