confused X86_64 and AIX

hello everybody i want to install some package on AIX 5.3
the name of rpm is something like libaio-0.3.106-4.2.x86_64.rpm is it a good rpm for AIX 5.3

my question is is AIX and x86_64 mean the same thing !

thanks

Those are two different things, AIX is running on power cpu's.
x86_64 is an intel based package. The package will not be installed (if proper built) or will not work. you need to find a power version of the package.
google for bull freeware or the linuxtoolbox (IBM provides some packages)

thanks :b:
