Hi,

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

The installation finished without any issue.

select * from v$version

----------------------------------------------------------------
Oracle Database 11g Enterprise Edition Release 11.1.0.6.0 - 64bit Production    
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

Because AMD invented it. Very Happy

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)
