Analytics Software

hi, i'm a green hand.

i've installed on Windows XP:
Oracle DB 10.2
ODI

now i try to log in ODI Designer with default username and password, as told in document 'Getting Started':
User: SUPERVISOR
Password: SUNOPSIS
, but always an error:

I want to know:

1. if there's really a default username 'SUPERVISOR' and password 'SUNOPSIS'?
2. if not, what should i do to log on ODI Designer?
for example i have to create a user in DB? then i have to use that Repository Management?
please be detailed, and step by step.

thanks.
