Hi

First thing Kernel update can be done at OS level only because kernel means the files that are present in the "run" directory.

1. download the database dependent and independent files from service marketplace (version of both must be same)

2. uncar both the files to a single location.

3. Imp: backup ur current kernel directory.

4. stop SAP and services related to SAP.

5. replace the old kernel with new one.

6. Restart SAP system and services.

These are the steps. Then check the version in SAP system.

Hello Rakesh Venkataramanan,

To update the Kernel Patch Level, follow the steps mentioned in the SAP Note 19466.

Hope this helps!

Hi ,

Go through the below links:

Yes you can do this in OS level.

In simple steps:

Down load the Kernel SAR from the service market place (Solution manager for new versions)

DB dependent ,independent will be there.

Take a backup of existing kernel.

Uncar the new kernel and place it in the exe directory.

Check the owner and permissions of the files.

Check the change of the kerenl patch after log into the system or from disp+work.

During this the application(SAP) should be down.

Thanks.
