SAP KERNEL UPGRADE - LINUX OS

Kernel: Kernel can be defined as a set of executable to run the SAP system. The procedure to upgrade the kernel is as follows: 1. First of all we need to make sure that the desired SAP kernel version is compatible with the existing OS Kernel version and SAP product versions with the help of product availability matrix (PAM). 2. After deciding the target kernel version, download the DB independent, DB dependent files (SAPEXE_***.***.SAR and SAPEXEDB_***.***.SAR) and place them in the server. 3. Create a directory in the server with the below command. mkdir newkernel 4. Copy the DB dependent and DB independent files into the newly created directory. cp –pr SAPEXE_***.***.SAR SAPEXEDB_***.***.SAR /newkernel 5. Extract the files using SAPCAR executable. (It can be downloaded explicitly or the existing one on the server can be used). ./SAPCAR.EXE –xvf SAPEXE_***.***.SAR ./SAPCAR.EXE –xvf SAPEXEDB_***.***.SAR 6. Once the files are extracted assign the suitable authorization and permissions for the executable. chown –R sidadm:sapsys * chmod –R 755 * 7. Now stop the application services and make sure that there are no processes running with sidadm user. 8. Take a consistent backup from the global directory. (Make sure to take the backup from the global directory as the backups taken in the local directories would be overwritten by the kernel in the global directory during application startup and in such cases reverting the kernel will not be possible). 9. Copy the newly extracted kernel to the global directory from the extracted path. cp –pr * /sapmnt/SID/exe/uc/linuxx86_64 10. Once the kernel is copied, check the kernel version using the executable “disp+work”. 11. Run the command ./saproot.sh SID with root user from the global directory. (This command assigns the desired ownership and permissions to the executable such as br**, sapuxusrechk, icmbnd etc.). 12. Once the checks are done we can start the SAP instance. 13. The SAP instance copies the kernel from the global mount-points to the local mount-points and application directories using the back end program sapcpe to all the application servers. 14. Once the instance is up and running, validate the kernel version from the application layer as well. ‪@sapbasishana‬ For MORE details - contact: [email protected] #SAP #BASIS #SAPHANA #SAPECC #TRAINING #PRACTICAL #JOBORIENTED #HANDSON #MIGRATION #S/4HANA #s4hana #IT #freshersjob #FRESHERTRAINING #freshersworld #STUDENT # ​#REALTIMETRAINING #BEGINERS #saphanatraining #saptraining #sapbtp #sapbasis #saptraining #sapbasishana
