Oracle 9i CD Packs

Hi,

I wonder if anyone can confirm the following information.

Even if it is used only for practice purposes at home, the “Oracle9i Database Release 2 (9.2.0.1.0) CD Pack for Microsoft Windows” has to be purchased together with trial licenses, and can run for only 30 days?

The cost of trial licenses seem to be $0.00 according to Oracle website.

Is that correct?
