We are developing a system using ATG and BEA with ORACLE as the backend on Solaris v2.8

There are two Sun boxes one of which hosts ATG and ORACLE
and the other BEA

Can someome point/tell me as to what is the best way of installing these s/w's.

I am non-tech manager and want to ensure that proper setup and CM policies are in place.

Thanks for your help in advance.
