Hi Guyz,
How do we know the SAP we are using is 32 bit or 64 bit?
I am not able to find out this information from the Status.I am planning for a Kernal upgrade for ECC6 and confused which(32 bit or 64 bit) Kernal to use.
Warm Regards,
Syam
how to find out SAP I am running is 32-bit or 64 bit is still unanswered!

Hi Syam,
Could you please check with the below linkw would throw some light ....
http://www.sap.com/solutions/benchmark/defaultconfig.epx under
32-bit/64-bit software version
also check : https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/2007a6a6-7608-2b10-2bbc-e583497c...

Dear Syam,
Please do refer to the note given by Manu . It is actually very old and not updated, but has generic command like once you navigate to exe\run (or a similar path to mine) of your server using command line/ command prompt, you can use disp+work.exe -version etc. In fact I will quote the whole section from it - Point - 12 - please note some of them might be outdated.
12. How can you find out whether an object is installed in its 32-bit or 64-bit version?
a) R/3 executables (R3trans, Kernel, tp, R3load):
cd /usr/sap/<SID>/SYS/exe/run
disp+work -version
R3trans -version
etc.
If no bit-version is mentioned within the text, this means it is a 32-bit version. 64-bit version would return something like .... COMPILED WITH 64-BIT LIBRARIES....
b) Oracle
as ora<SID> user start svrmgrl
In the header it shows oracle-version and bit-number.
you can also do a SELECT * FROM V$VERSION;
Oracle client-lib
library oracle is using CD $ORACLE_HOME/LIB
FILE LIBCLNTSH.<EXT>libary the R3-tools are using
Please check note 180430 for your R3 release specific oracle client note. The location of the clientshared library has changed with different R3 releases. Get the location of the library from that note and then execute:
cd <directory where the clientlib is in>
FILE libclntsh<version>.<extension>
Most kernels also have the function calls to the oracle libraries extracted to a new library dboraslib.<extension> Please also check this library:
cd /usr/sap/<SID>/SYS/exe/run
FILE dboraslib.<extension>
c) OS
HP:
getconf KERNEL_BITS executed as root user returns either 32 or 64
DEC-UNIX:
automatically 64-bit - also shows with the command /usr/sbin/sizer -v
AIX:
beginning with release 4.3.1 64-bit; please make sure that all hardware components are 64-bit. When installing 4.3.1 AIX automatically detects whether your hardware is 64-bit and will install the necessary 64-bit software components. The easiest way to find out whether AIX is 64-bit is by the following commands:
lslpp -l bos.64bit - this should return a line that bos.64bit is installed
genkex | grep 64 - this checks whether the 64-bit kernel extension is installed. it should return something like
149bf58 a3ec /usr/lib/drivers/syscalls64.ext.
For further details refer to the following webpage http://www-1.ibm.com/support/ docview.wss?rs=0uid=aix12465b658044fc574852569e70056e923
SOLARIS:
isainfo -v
Hi Syam,
To confirm your os you can get the info by platform id.Check the below link for the information

Dear Syam,
Some of the IDs in the above link may not be correct. For example, the Platform ID for Windows 2003 Server x64 is 562 whereas the link mentions Windows 64 bit as 561 (not mentioning whether it is x64 or IA64).
By the way you can check the platform ID by going to System->Status in SAP GUI after logon.

Hi Veeraraagavan R / Manu,
Now I know how to find out from SAP weather the OS is 32-bit or 64-bit. But my query is still unanswered. I do not know how to find out if the SAP I am running is 32 or 64 bit.
Note: I confirmed that 32 bit SAP can run on 64-bit OS. Interestingly one of my friend has installed 64bit SAP on 32 bit OS following the note Note 1244548 - IDES ERP 6.0 ECC 6.0 SR3.
Warm Regards
Syam
Dear Syam,
If you are using a 32bit OS, then your kernel would be 32bit. If you are using a 64bit OS then your kernel would be 64bit.
Please mark the question as answered if my post solved your question.
Regards,
Veera

Dear Syam,
I dont know if it is possible to install a 32bit version of SAP Server on 64 bit OS, because I think the Prerequisite Checker would have warned the same, but in x64 implementations there is an x86 (32 bit) compatibility layer, which may allow you to run a 32 bit app seamlessly.
In general, you can check your DB also, if it is running 32 bit, ur server is also going to be 32 bit.
Loosely, you can use the link given by manu above for making sure.
Regards,
Veera
