Requirements for SAP Kernel patch

Post by mwiese » Tue Dec 17, 2013 9:43 am

Hi all,

since years we're patching the sap kernel without any big problems.
But what do you do, if the applications guys encounter errors during their tests? It the kernel patch really the root cause of this problem? Or might it be another issue independent of the kernel?

So my question is: Are there any requirements that you have to fullfill, in order to patch the SAP kernel, e.g. empty delta queue (SMQ1)?
Are there any sap notes regarding this case?

Thanks and best regards

We patch kernel only during support packs, upgrades, EHP installs or if an installed kernel has a known issue that is affecting.

Other than that, why try to fix something that ain't broken?

HI Marco,

Like Snowy, we upgrade the kernel during Support Package application, EHP installs, etc...

I remember being surprised by some application issues right after a kernel patch years ago.

Thus, there may be application issues, though I think that it is rare now. I don't remember coming
across recommendations to empty the delta queue, etc... If you come across something like
that, please post it.
