How to update Kernel in SAP?

Jun 17, 2013 by

Dear Readers,

This guide is going to explain the steps required to update the Kernel version of an ABAP instance of a standalone server.

First of all, you need to download the latest version of your kernel (independent & database parts) from SAP Marketplace. You can find it here, Support Packages and Patches –> A-Z Index –> “K”, and download the appropriate version depending on whether your system is 64 or 32bit, or unicode or non unicode.

1.- Copy the .SAR files and unzip them with sapcar in the same folder called “Kernel version”, and copy it to the SAP Kernel’s directory (/usr/sap/<SID>/DVEBMGSXX/exe/run/uc/NT*). It might vary whether it is UC or NUC.

2.- Stop SAP.

3.- Copy your current kernel to a new folder named “New Kernel”

4.- Copy the contents of the folder “Kernel version” to “New Kernel” and overwrite.

5.- Rename the name of your current Kernel to “Old Kernel”

6.- Rename the folder “New Kernel” to the name of your current Kernel.

7.- Start SAP.

You can open a CMD and write “disp+work” to see whether or not you have the correct version.

Kind regards,

PIU
