Dind't understand the doubt's
I've posted various places over the last few month's. Sun and Oracle in their entireties makes sense. OracleDB + Solaris + Sparq is and institution in government and big enterprise.
This is an excellent play by Oracle against IBM's market dominance and vertical integration. DB2 is a threat to Oracle as IBM could pull a Microsoft and offer it a huge discounts during server/mainframe sales and upgrades.
It's a ballsy gamble, but a good one.
I think it will give some direction for Sun as well. Something they seem to desperately need.
