Regarding Profile of SAP WAS

Hi Everybody,

I am a beginner,i am doing my intership in SAP BW.

i want to send mails from the Business workplace of SAPBW. i read the help notes and came to know that i have to "ADJUST THE PROFILE OF THE SAP WAS ,IF I WANT TO USE THE SMTP FUNCTION".

using trans. 'RZ10',i found three profiles in my SAP BW system,those are:

1.DEFAULT PROFILE

2.START PROFILE

3.INSTANCE PROFILE.

which one of the above is the SAP WAS profile.

How to know which version of SAP WAS was installed in my system?

Thank you
