[Zope] read-only-database

[Ulla Theiss]

Hello list,

I want to run the database in read-only mode from CD and configured it 
accordingly in the zope.conf:

read-only-database on
enable-product-installation off
zserver-read-only-mode on

Starting Zope, I get the following error:

Traceback (most recent call last):
  File "\Programme\Zope\lib\python\Zope2\Startup\run.py", line 56, in ?

r+ means opening the file for updating. This has not to do anything with 
read-only.

Does anybody know what I have to configure additionaly, that read-only 
works?

I run Zope 2.8.4 on windows.

Many thanks in advance,
Ulla.
