Hi Pierre,

Steps for upgrade:

1)

Stop these services:

- saposcol

- sapservice (instance name)

2)

- download 640 kernel with latest patch

- backup "\exe\run" catalog

- unpack new SAR archive

- copy new kernel to "\exe\run" catalog

3)

Register new service in program sapstartsrv.exe

4)

Start instance

If You have any problem, You can back to original kernel by copying old "exe\run" catalog to proper place, register old services with sapstartsrv.exe and run the instance.

Hi Marcin,

There is some problem after upgrading, my dispather stop after few seconds.

When I start the instance, system runs about 30-40 second and become 'yellow'.

Any ideas?

Thanks,

Hi Pierre,

In program sapstartsrv.exe try to register COM library. Your new kernel have newer DLL's.

HI,

I found something like that:

"Version mismatch between kernel (640.00) and DBSL shared library"

am I do something wrong?

You missed a Database library in upgrade.

Go to service.sap.com -> ... -> search for kernel 6.40 -> SAP KERNEL 6.40 32-Bit -> Windows server -> MS SQL Server -> download Database Library (eg. lib_dbsl_152-20000184.SAR)

Unpack it and copy to exe\run directory

Hi Marcin,

I am on right track to install the kernel, I should download the database dependent and db independent .SAR file and then update the kernel?

I have downloaded SAPEXE_196-20000182.SAR and SAPEXEDB_196-20000185.SAR files.

Is it right or do I need to download something else for it?
