Can you provide some more detail? How are you applying the new files contained in kernel 640? Have you extracted these in a separate directory?

Thanks,

Hi,

1. You should extract kernel files to temporary directory

2. Stop SAP system (and kill all sapstartsrv.exe windows processes running in context of SAPService<SID>

3. copy new kernel files to

<DRIVE>\usr\sap\<SID>\SYS\exe\<kernel type: like UC/NUC>\<processor :like NTINTEL/NTAMD64>

4. Start SAP system : During start SAP system updates executabled from directory (3)

After starting SAP system right click in MMC on dystem and select option Display version to check if all files were updates.

Hi Subhash,

Whenever you are doing Kernel upgrade .....(take the backup of old kernel)

1)U need to stopsap and stop all the services like saposcol and all related to sap.

2)Keep the .SAR files in a temporary dir like /tmp

3)Extract the SAR files into a new directory like /tmp/newkernel

3)Then goto ur kernel directory /usr/sap/SID/SYS/exe/run

4)Give the command as cp -Rf /tmp/newkernel/* .

5)When u execute this command all the kernel files will be updated in the run directory .u can see the date of modified also.

6)After that check the disp+work version by giving the command

disp+work -version

This will give u the kernel version (Latest).

7)startsap

8)Change the permission of SAPOSCOL to root and the permissions shd be like -rwsr-xr-x .

9)Then check the version in SAP level.
