32 bit or 64 bit kernel for z/OS

Hi All ,

We have our SAP R/3 4.7 installed in z/OS with DB2 as the database. We have recently upgraded our kernel to the latest version . The path from which we downloaded our Kernel is

My Company's Application Components" SAP KERNEL 32-BIT" SAP KERNEL 6.40_EX2 32-BIT > z/OS 32bit

Now the system is up and running but in our EARLY WATCH REPORT we are getting this particular warning

"You are running a 32-bit SAP kernel on a server with a 64-bit operating system.

Recommendation:

32-bit SAP kernels are subject to many restrictions regarding memory management. A 64-bit SAP kernel version is available for your 64-bit operating system and SAP kernel version. Consider switching to this version."

But we are unable to find the 64 bit kernel for z/OS in the download location

My Company's Application Components" SAP KERNEL 64-BIT" SAP KERNEL 6.40_EX2 64-BIT

I wanted to know if there is any 64 bit SAP kernel for z/OS ?

Are we getting a False warning in EWA , if so how to correct the error ?

Thanks and Regards

Basis Team

Hi ,

The kernel for z/OS can't be found in the path you have mentioned . Our system is a non Unicode.

  If you've always run with a 32 bit system you can ignore the message as it is possible to run a 32 bit kernel with 64 bit OS. The 64 bit kernel should be available for download from the marketplace and is better to use on a 64 bit os.

There is no z/OS 64bit kernel on 6.xx based systems. Just ignore this wrong warning in EWA.

  Better yet, why not open an OSS message and ask SAP to correct the earlywatch report so it does not show a warning for 32bit kernel on 64bit OS when the SAP version is 6.xx and the OS is z/OS? That would only make sense if they have not provided a 64bit kernel, and it sounds like they have not.
