Former Member

Hi Guys,

I am trying to apply kernel in prod box where I have DB+CI and one more CI got installed. current system is aix and oracle 11g I am trying to upgrade the kernel before Oracle11g upgrade it throws diff error. Mostly I am getting errir with dboraslib.o files and all the .o files. some time I got the error from libic files

My oracle database is up and running if I replaced kernel where as the SAP R3 is not starting thro script. The same kernel I succefully uploaded for other dev and QA Boxes here.

Last step also I did after the upgrade ./saproot.sh <sid> and did sapcpe pf=...... command also. trans.log says some ora error some time and R3trans -d says library files mismatch with 700.08 and 720.. I am confused here..

Still my kernel is not succeed and not working. Could you please suggest on this?

Thanks,

Sankar G

Hi Sankar,

    It seems that you haven't upgraded the kernel properly. Please follow the below steps.

1. Stop all the SAP  & DB related services.

2. Check using ps -ef  | grep orasid and sidadm and see no DB or SAP services are running.

3. Extract the kernel  as well as please download the lib_dbsl from the service.sap.com/swdc

4.Uncar all these files in a folder.

5.Take a backup of your working kernel from the following location

/usr/sap/SID/DV*/exe

/sapmnt/SID/exe

6. Manually overwrite the uncared kernels in the above two locations.

7. Start the DB and SAP .

8. It should come up..

PLEASE MAKE SURE THAT YOU ALSO DOWNLOADED LIB_DBSL Files and updated it in the kernel.

If you are still facing the issue, please attach the error screenshot.

Thanks and Regards,

Vimal

Good Day

What you need to do is to read this SAP note:

Note 1636252 - Installing a 7.20 kernel in SAP Web AS 7.00/7.01/7.10/7.11

It clearly says that you need to delete all local executable and put the new kernel in the /sapmnt/SID/exe directory and shoot sapcpe against the instance profile.

Hi Sankar,

   Your application server patch should also be same like in  your CI box.

Please update your kernel patch in Apps that equals to CI kernel and check..

Apps should start up after kernel patching.

If still not getting updated, please attach the dev_w0 log for more anlaysis.

Thanks and Regards,

Can you explain the procedure you used to upgrade your kernel?...

library files mismatch with 700.08 and 720.

It seems to me that SAPCPE has not distributed the kernel correctly.

The systems are in cluster and DB+CI on one box and other CI is diff box. Cluster files are running and mounted with local name and when ever cluster start or stop it will move. The oracle db is running at DB+CI box.

I took the backup of kernel and copied kernel to exe/run folder whichever needs to modify it got modified. before that i stopped saposcol also.

then I ran ./saproot.sh in root prompt. the I did sapce command for Centeral Instance and Start profile for SCS00 and ASCS00 and DI also.

Kernel thrown error dboralib.so and R3trans -x also not worked. thrown error like dwc_xt some file is nor reading lile that.

Plesae suggest and provide procedure .. The same kernel is working with DEV and QA well

that is strange !! also tell me how to use sapcpe and what are the profiles to be done and syntax please.

Thanks,

Hi

Please confirm whether you have upgraded the kernel in

/usr/sap/SID/ASCS***/exe

If not, upgrade there also...

You can use sapcpe  using the following command

sapcpe pf=/usr/sap/SID/SYS/profile/ instance profile

Hi Sankar,

   I dont have any idea.. But I think if you update with the following files, your issue might be fixed.

1.dw_421-10007272.sar

2.dw_utils_417-10007272.sar

You can see it under kernel Database independent.

Download it and extract it to the exes folders and check please.

Sometimes, it could also be a bug in your present kernel you have downloaded and used.

I feel it is worth to give a try in this way

Thanks and Regards,

Vimal

Hi Sankar,

You need to rename .o files using command mv <old filename> <back upfile name>

Post this kernel upgrade will work fine.
