how to activate DB50 & DB59 in was620

I have miniWAS620 installed, but when I go to DB50 to check configuration I get an error message of 'NoDBCONUSREntry at DB Instance CreateObject'

And DB59 does not show the local SAPdb instance listed.

Any way to activate this?

thanks

Gary

ps I searched back page by page to early 2005 and found nothing that seemed to match the problem.
