scrbook page numbers margin problem

I was looking for the setting to adjust the vertical margin of the page numbers in the scrbook class but haven't found anything. I want to have them "nearer" to the page margin.

\documentclass[oneside,ngerman]{scrbook}
\begin{document}
Some text
\end{document}

KOMA doesn't provide such a feature. For special settings you should use the package geometry which is recommend in the documentation. You should use the option reset of the package geometry to set the original margins of KOMA. –  Marco Daniel Mar 15 '12 at 17:09
Thank you very much, the following code achieves what I want (I've changed the original post as I cannot seem to post code in comments). However, what is the default margin? –  Jan Mar 15 '12 at 17:58
Use the option reset. –  Marco Daniel Mar 15 '12 at 18:11
Your set screw to influence the type area is the DIV option for the document class. DIV=12 seems to work fine here. Other settings for the »typearea« package are described in the KOMA-Script user guide. –  Thorsten Donig Apr 24 '12 at 18:54

\usepackage[bottom=10em]{geometry}
