I would like to know following points with reference to Oracle Database.

1. Can we create a database of size 300GB & what is max. size one can go for?
2. Technically, is there any limitaiton on its size.?
3. Does it have any peformance issue / response problem? H/w is no issue in this case.
4. Does this maximum size varies OS - to - OS & different version of oracle?

Can anyone address these issue & let me know. Thanks.
