Urgent help on Oracle 9 databse

Dear Gurus,

I am installing the R/3 4.7 Enterprise Ext 2 SR1 On Windows 2003 64 bit version & processor is Xeon 3.4 Ghz (AMD).

I am planning to install oracle 9 on this system but there is no supported kernel for Oracle 9 on windows x66_64 64 bit operating system as per the Note 814834.

I wanted to know if I install Sapinst for 32 bit on the 64 bit OS it will work or not ? If it will then is there any performance issue ?

Waiting for the reply.

Thanks & Regards,

Sachin Sable
