Download Kernel from Service Marketplace

Go to “SAP Service Marketplace. ” (https:\service.sap.com) You will need your OSS ID and password. Then go to Downloads à SAP Support Packages -> Entry By Application Group -> SAP Kernel 6.00 64 Bit -> Select your OS (LINUX/WINDOWS/SOLARIS/AIX) -> Database Dependent and Database independent Kernel Patch.

Database Independent

Database Dependent: ORACLE

Kernel Upgrade Steps:

Step 1: Create a new Directory at OS level with enough space. Name of Dir can be “exe_new”. Step 2: Transfer these SAPEXEDB.SAR & SAPEXE.SAR files which you have downloaded to the new directory at OS level. Step 3: Change your current directory to path .SAR files are created (cd /sapmnt/PR2/exe_new20122006). Check the directory path with command ‘pwd’ to ensure you are in the same dir (exe_new). Step 4: Now uncompress these. SAR files by sapcar exe. The command used for the same would be

Step 5: Now create one more directory in that path with the name “exe_old”. Take the backup of existing kernel.Copy (only copy not move) the existing kernel from exe directory to “exe_old” Step 6: Now stop the SAP application. (For kernel upgrade the shutdown of database is not essential but we need to stop the SAP application) Step 7: Then copy the files from the new kernel directory exe_new to the existing kernel directory exe Step 8: This will copy / replace all the files in the existing kernel directory with a new kernel files. Then check the kernel version from OS level by the command disp+work. It should show that the patch number has been increased. Step 9: Then logon to OS level as root (specific to UNIX). In the kernel directory, there is a script called saproot.sh. Execute this script Step 10: This script assigns the correct permissions to all the executable programs in the kernel such br* file etc… Step 11: Then start the SAP system Step 12: Now you can also check the kernel version level from SM51 or by selecting system à status
