Native Kernel
The kernel version of SAP in Windows can be checked by using the GetVersionInfo function of the sapcontrol command. This command displays information about native executables like jcontrol, jstart, jlaunch, and sapstartsrv which are written in C-code. To update these executables, files like SAPEXEDB.SAR and SAPEXE.SAR can be used.
Java Kernel
The Java binaries of the J2EE Engine, including files like boot.jar, jstartup, and jaretc, are responsible for its functioning. These binaries can be modified or upgraded during system releases or Support Package Stack (SP/SPS) upgrades. The kernel version can be easily viewed through various tools such as the System Information page and Visual Administrator.
