Kernel upgrade :
For Dual stack:
1)from service market place,you have to download the .sar
files.there will be a total of 3 files having following
format :
SAPEXE_<Patch level>-<release date>.SAR - database
independent file
SAPEXEDB_<Patch level>-<release date>.SAR - database
dependent file.
there will be a database library also aong with this file.
Once you have downloaded all the files, you have to uncar
them using below command:
sapcar -xvf <file name>.
Uncar all the files in a temporary folder.
Now stop sap,DB,all services.
then take a backup of the run folder where kernel resides.
Now copy all the recent files from the temp folder that you
have extracted.
Again start DB,SAP, and all services.
Now check if your kernel is patched.
In case the system doesn't comes up we can again use the
backup kernel folder.
In case of java stack there is no kernel upgrade done
seperately.it is done along with SP upgrade via jspm.
