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.




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
