what is the difference between normal Kernel 7.20 and the Kernel 7.20 EXT

what is the difference between the normal Kernel 7.20 and the Kernel 7.20 EXT

and please, do not post only a link to sap-note 1553300 or 1553301 ,

unfortunately, there's a lot of vaguely and unclear text in these sap notes, but

nothing that describes the difference between the "normal" and the "extended" kernel,

is EXT only another word for downward-compatible Kernel or is it more than this?

any helpful and understandable explanation of the difference? "normal" Kernel 7.20 and the Kernel 7.20 EXT

    Hi,

    please check SAP note 1591607.

    Kernel 7.20_EXT is a MUST for SAP Netweaver 7.03 / 7.31.

    However it is also downward compatible to NW releases listed in SAP note 1553300.

    Best regards,

    Nils Buerckel

      Christoph,

      Recheck the note mentioned earlier (1553300):

      "SAP Kernels are built on a specific version of the Operating System and compiler.

      When the OS or the compiler which are used during the builds run out of vendor support customers could run into a support problem. SAP therfore needs to provide a newer kernel which is built with the newer / supported version of the OS and compiler.

      Against this background, an update of the SAP kernel make environment is required from time to time resulting in newer kernels being made available for the customer. Using these newer kernels ensures that customers can operate a fully supported environment at all times.

      From a compliance perspective it is important that a customer environment is a fully supported one. Some of the compliance regulations (SOX, FDA) also require that customers use supported software environments."

      Then, the difference is that the EXT kernels are compiled in a fully supported environment (OS and DB).

      Cheers,

      Diego.
