Database Software

Hello

I am wondering how 10g really works as a grid clustering system distributed over the internet or as a simple clustering over an enterprise network.

Over all, to work as a grid system, the application server/database needs to have its computing power distributed over a wide network of machines distributed over the internet AND enterprise's LAN.

If I decide to upgrade my enterprise application server and database to a system such as 10g, I will therefore of course allocate computing cycles from available resources existing within my LAN, dedicating machines, network resources and disk spaces to it, as I would do for any other product.

But, overall, the interesting feature of 10 g is to fetch resources from "abroad". So my question is about the following topics:

1) Where will these grid resources be found ? does Oracle rents its own computing power to licencees ?

2) On an other hand, if my company's computing power is "gridded" (forgive this neologism, I did not find any equivalence) will it be also distributed to Oracle or some of its "gridded" custommers.

3) Business planning of resources: what is a gridded computing power unit (a computing cycle dedicated to grid, a grid time unit, a grid workload per unit of time) ? and how much does it cost ?

4) if, for instance my company's workload decreases at a certain schedule, can I, in that case allocate power to the grid and be paid for. If possible, I guess this process can be monitored.

5) And what if I have absolutely NO personnal nor company need for grid power but a huge amount of spare cycles, disk space and computation power ? Could I, in that case, become a "grid power supplier" such one could do with seti at home" clients, and therefore earn money with that ?

Thanks for enlightenment
