32 bits or 64 bits....

Hi guys!!

How can I determine that a system is set to operate in 32 bits or 64 bits???

Thanks
Jonathan

OK thanks Pete, getconf KERNEL_BITS work fine....

Now, I have a compiled application (PeopleSoft 7.5) on an old box running HP-UX 10.20, so I supposed this app is running in 32 bits... Now I want to transfert that application on a new system running HP-UX 11... will it be possible???

I borrowed this from Procura's FAQ:

You can find out if your kernel supports 64bit binaries by issuing:

a5:/usr/local 110 > file /stand/vmunix
/stand/vmunix: ELF-64 executable object file - PA-RISC 2.0 (LP64)
a5:/usr/local 111 > getconf KERNEL_BITS
64
a5:/usr/local 112 > getconf HW_32_64_CAPABLE
1
a5:/usr/local 113 >

HP-UX 10.20 does not support 64bit objects

This command will tell you:

# getconf KERNEL_BITS

Hi,

One other way to check is to run Glance and go to the system tables screen [press 't' if you are running the character version]. The bitness of the installed OS is shown on the second screen. The advantage of this method, if you have Glance installed, is that you don't have to be root to get the answer.

If you are looking for Server's and Workstation support matrix for 32/64 bit OS, then check here:

Jonathan,

Sure, your 32 bit app will run fine.

Actually, I should say that your application will *probably* run fine. I've copied many apps over to 11.0 and 11i systems without problem.

Your best bet is to double-check with PeopleSoft.

Another good reason to have my 'ux' script handy (get it from https://www.beepz.com/personal/merijn/ or http://www.cmve.net/~merijn/)

a5:/ 101 # ux
a5 HP-UX 11.00/64 U 9000/800/A500-7X/64 PA8700/750(2) pa-2.0 2048 Mb

Enjoy, have FUN! H.Merijn

Jonathan,

Another way to find out whether your OS mode is 64-bit is to run:

# /opt/ignite/bin/print_manifest

to determine if system is running 32 or 64-bit kernel via SAM, do ;

- Performance Monitors
- System Properties
- go to TAB ; Operating System
- check OS Kernel Width

although in my opinion
command line is faster

Robert Gamble — Fri, 07 Mar 2003 13:02:44 GMT

More commands that will work:

getconf KERNEL_BITS

or

getconf MACHINE_MODEL

I would agree with Pete that it is most likely that your program, especially a program widely known as PeopleSoft will *likely* work on 64-bits machine. But if you are running 11.0, I would also check to see if HP-UX 11.0 has been loaded in 32 or 64 bits. But again, and like Pete said, check with your PeopleSoft people, to make sure of any "gotchas".

Merci!

FWIW, the liklihood of KERNEL_BITS returning 32 is diminishing every day. The only place where one can find a system running 11.X and a 32-bit kernel is on systems with PA-8000 and PA-8200 CPUs (ie D's, K's, R's and "three digit letter workstations"). Any system with a PA-8500 or later CPU, including IPF, and running 11.X will be running a 64-bit kernel. At least anything running in an HP supported configuration.
