How to know if the installation is 32 bit or 64 bit

[Ali Imran Abbas]

I am new to HP UNix. I wanna know the servers have 32 bit of installation or 64 bit. HP UX is already installed on the server.

Hi:

All Itanium servers are 64-bit only, as are the more recent PA-RISC series. You don't offer your server model nor your operating system version. That said:

# getconf KERNEL_BITS

...will tell you the "bitness" of your current kernel, e.g. "64"

# getconf HW_CPU_SUPP_BITS

...will tell you the "bitness" your hardware will support, e.g. "32/64"

Ali,

The previous postings mention getconf, that covers the OS.
For application code binaries & third party software use the 'chatr' command to determine which libraries were used in the compilation. Even for Itanium running 11.23 & 11.31 there is a lot of 32bit source out there.
