Answer / lalit rana

To check if your R/3 system is 32bit or 64bit you can get
it by executing "disp+work" file which is part of your
kernel in /sapmnt/<SID>/exe. Just follow the following step:

su - <sid>adm
cd /sapmnt/<SID>/exe
disp+work

When you execute this file it will give the output which
will contain the following line.

disp+work information
--------------------

kernel release 640

kernel make variant 640_EX2

compiled on AIX 2 5 00029F1AD300

compiled for 64 BIT

compilation mode Non-Unicode

compile time May 31 2009 22:26:33

update level 0

patch number 286

source id 0.286


You can see in the above lines stating "Complier for
64bit". Incase of 32bit it will show 32bit.

Hi,
To know whether the system is 32 or 64 bit one should know
that a R/3 system is installed only on NT based platform
i.e : one can install r/3 system on NTFD file system and
not on FAT file system.
