64 bit or 32 bit system?

[Michael McGrath]

We have an HP-UX system installed by people that disappeared in the crash, and for which the documentation is lost, stolen or strayed. Nobody here seems to know how to query the OS to find out if this is a 64-bit or 32-bit system. uname -a returns: HP-UX B.11.00 A 9000/871

Any guidence would be much appreciated...

Hi,

Running 'getconf' program will tell you

# getconf KERNEL_BITS
will inform you of what the current kernel is configured as.
using

# getconf HW_CPU_SUPP_BITS
will inform you of what your hardware is capable of. The 'getconf' program only works on systems that are HPUX 11

Also have a look at this link which gives information on what hardware can run what bit operating systems.

Hi,

Might help if I give you the best link for the
compatibility chart. Try this one.

Hi,

Some other methods:

1) Using swlist:

# /usr/sbin/swlist |grep "HP-UX 64-bit"
HPUXEng64RT B.11.00.01 English HP-UX 64-bit Runtime Environment

2) Using kmtune:

# /usr/sbin/kmtune | grep maxdsiz_64bit
maxdsiz_64bit XXXXXXXXXXXXX

3) Using sam:

Go to system properties. Select the appropriate CPU tab.

Hope this helps. Regards.
