    where have you updated your SAP kernel?

    do you have this directory? X:\USR\SAP\[sid]\sys\EXE\<b>nuc</b>

    if so, update your kernel in this directory and restart your SAP instance.

    the startup profile caqlls a program called SAPCPE which copies the kernel from this directory to X:\USR\SAP\[sid]\sys\EXE\run

    Hi,

    Before coping the kernel, you should bring down SAP, then stop SAPOSCOL, then stop the sapstartsrv. and then clean all the semaphores owned sidadm. here is the steps

    stopsap all

    stopsap sapstartsrv DVEBMGS<abap instance no>

    stopsap sapstartsrv SCS<java instance no> ( If java stack available)

    saposcol -k

    cleanipc <abap instance no> remove

    cleanipc <java instance no> remove

    slibclean ---> execute this command as root.

    Then after executing all the commands then copy the kernel to run directory.

    Hi All,

    Thank you Eric for your prompt reply.

    I have already tried your option updating the kernel files in the directory X:\USR\SAP\[sid]\sys\EXE\nuc and restarted the SAP instance.But my doubt here is, the subdirecory of nuc is NTi386 which was updated.Did i go wrong?

    We have windows 32 bit environment.

    Thanks,

    Naresh

      Hi,

      Have checked the log files and also the dev* files in work directory.

      Please also check any errors found in the work directory. some times due the saposcol problem , sysem will not release the complete memory.

      As you are on windows, please stop saposcol service and then, replace your new kerenals .

      Try to restart the sap.

      Hope this will help you.

      Regards

    Hi,

    I stopped SAPOSCOL before updating the kernel files and I checked all log files in work directory and found everything fine.

    Thanks,

      Hi Naresh,

      Can you open the sapcpe.log file at your \usr\sap\<i>SID</i>\<i>DVEBMGSxx</i>\work\ dir?

      Please, post the first & the last 20 lines (aprox), and/or look for any error there...

      Best Regards,

      JC Llanes.
