Need help in kernel upgrade

[Former Member]

Hi,

The kernel patch level reverts back to the old kernel when I started SAP after the kernel udate. This is my first time to upgarde the kernel for win IA64, SAP netweaver04 & Oracle9i. I am used to unix installations.

Here are the steps I had made for the upgrade. After downloading sapexe and sapexedb, I extracted it into a temporary directory and did the following:

1. shutdown SAP including the services.

2. back-up the old kernel.

3. copied the new kernel to the \usr\sap\SID\SYS\exe\run directory.

4. check some of the exe files in the target directory and verified that it was copied correctly. (tp = patch level 193, date stamp 2007)

5. restarted the server

6. started sap.

7. checked system->status->Kernel Info

It still shows the old patch level.

8. checked some of the exe files again in the target directory it now shows tp = patch level 39, date stamp 2004)

why did it reverted back to the old level? Please help.

thanks

I guess this is because you didnot copy the files to \usr\sap\SID\SYS\exe\NTIA64\uc or nuc directory..

Please do this and your problem will be solved

Please note that whenever you do a kernel upgrade you will have to copy the files of the new kernel to the \usr\sap\SID\SYS\exe\run as well as to the directory \usr\sap\SID\SYS\exe\NTIA64\uc or nc (as applicable)

Hi Kbas,

I agree with Bidwan on this one..

You need to update the kernel at \usr\sap\SID\SYS\exe\NTIA64\uc or nc.

Hi,

The steps seems to be absolutely right.

Pl check the document NW_SP_STACK04_105.

U can download it from http://service.sap.com/instguides under SAP------>NetWeaver → Release 04 → Maintenance.

Pl check the 2.1 Patchable Components portion at pg 14 of the said docu.

Hi,

All the steps you have menioned are properl sequenced steps.

Kernel should get updated.

One possibility for not getting uodated might be unicode/non-unicode kernel.

Just check whether you have updated relevent kernel in terms of unicode and non-unicode.
