Check Kernel version of J2EE Engine

How to check kernel version of J2EE Engine?

Two types of the kernel are in SAP NetWeaver Java system:

  • Native Kernel
  • Java Kernel

Native Kernel:

  • Native Kernel is executables of java startup framework which are written in C-code, like jcontrol, jstart, jlaunch, sapstartsrv etc.
  • We can update using file like SAPEXEDB*.SAR and SAPEXE*.SAR.
  • GetVersionInfo function of sapcontrol command can display the kernel version.

Java Kernel:

  • Java Kernel is a java binaries of J2EE Engine itself, like boot.jar, jstartup,jar…etc
  • We can update it during system release or Support Package Stack(SP/SPS) upgrade.
  • The System Information page and other tools like Visual Administrator can display the kernel version

Note:

  • When SAP Consultant request for kernel version, which implies that Native Kernel unless clearly mention to get Java Kernel
  • If the user only performs the update for Native Kernel then they only need to follow [For Native Kernel version] section to confirm whether kernel indeed gets updated to expect one. The user doesn’t need to follow the [For Java Kernel] section.
  • Updating Native Kernel do not affect the version of Java Kernel.
