[CentOS] Centos and Oracle

[Szemerédy Gábor]

Hello llist!
I have Centos 5.2 installed!
Would like to use Oracle on it.So I downloaded Oracle Apllication server 
10g rel. 3.
We need to develop and use Oracle Forms applications. Do we need to 
install 10g Developer Suite also or are the forms contained in the 
application server?
If we need the Developer Suite also , please tell us where from to 
download it.
Thanks
