Hi,
The DB server is Intel CPU based then why oracle says its on AMD?

PL/SQL Release 11.1.0.6.0 - Production
CORE 11.1.0.6.0 Production
TNS for Linux: Version 11.1.0.6.0 - Production

select platform_name from v$database
PLATFORM_NAME
-----------------------------------------------------------------
Linux 64-bit for AMD
Thanks
Amit

Because AMD invented it. 
Do you remember the "Itanium" processor? That was the 64 bit technology developed by Intel. It didn't catch on, since it wasn't backward compatible to x86 code.
That's why Intel licensed the x86_64 technology from AMD, and a lot of "Processor information" outputs of various OSes report all x86_64 based processors from both AMD and Intel as "AMD64" because of those historical reasons. (When there was the distinction between AMD64 and IA64)
