One app server still shows old kernel version after kernel upgrade

0 Kudos

Hello All,

WE have upgraded kernel version from 753_REL - 215 to 753_REL 400 in 7 app servers of our ECC production system.

However after kernel upgrade, the disp+work in app 4 shows the latest while release notes in SAP - SM51 shows old (215)version.

The other servers are fine. This problem is only with app 4. Please help!

Thanks,

Uday

Hello Uday,

Confirm that all the servers are accessing the same "SYS/global/exe/..." folder structure and look for any issues at the "sapcpe*.log" files under the "work" folder of the affected instance.

You could also provide the "sapcpe*.log" files in this thread, as well as the profiles for the affected instance, so we can take a look and see whether we spot anything.

Regards,

Isaías

Hi Udaya,

You need to update the kernel in central directory which should be
\\<SAPGLOBALHOST>\sapmnt\QPC\SYS\exe\uc\<OS> - on Windows and with forward slash (/) on Unix

and restart entire SAP system. sapcpe program then should automatically copy updated kernel from central directory to instance specific directory: \usr\sap\<SID>\<INSTANCE>\exe

If above don't work, that points an issue with sapcpe copying updated kernel. Technically you can manually copy/update kernel in each instance specific directory but ideally you shouldn't need to.

Hi Uday.

1. Have you copied the kernel files in CI share folder \usr\sap\SID\SYS\exe\uc\NTAMD64\ ?

2. After updated the folder, start the SAP application instance . Could you share the CI & app instance OS / DB deteails?
