Differentiate 32 bit and 64 bit

[Syamkriz]

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...

Hi Manu,

I checked the above mentioned link. The link just say that there is 32-bit and 64-bit SAP avaialable and benchmarking for both differs. Other than that the link doesnt help much.

Dear Syam,

See the default path for 32 bit kernel is this:

drive:\usr\sap\<SID>\SYS\exe\run\

I am having a unicode NW 7.0 server on Win 2k3 x64 and my kernel path is

drive:\usr\sap\<SID>\SYS\exe\uc\NTAMD64\

I think this should solve your problem.

Hei Syam,

Got it look into sap note Note 192822 - FAQ: 32-bit/64-bit R/3-oracle

12. How can you find out whether an object is installed in its 32-bit or 64-bit version?

you have solution under this please ref the note.

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 In fact I will quote the whole section from it - Point - 12 - please note some of them might be outdated.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.

Hello Manu,

Thank you very much for your reply. With this platform id , How do we realize which( 32/64/128 bit ) OS is this ?

Warm Regards

Hi Manu,

Ignore my last message to you- Now I know how to use that link to differentiate 32 bit and 64 bit. Thank you very much.

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.

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.

Hi Veeraraagavan R,

Thank you very much for the reply.Now I got another querry.Please help

That means ,if I Install 32-bit version of SAP in a 64-bit OS, I must use a 32-bit SAP Kernal?

Warm Regards

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.

Veera

Hi Veeraraagavan R ,

I am running an Oracle 1Og and ECC 6.0. Could you please tell me how do you I check if my db is 32 bit or 64 bit.Once again thanks for your kind replies.

Warm Regards,

Syam
