Hi all,
A solution has been found. woohoo. A not found error was produced with
direct URL traversal.
Steve Spicklemire sent this solution off list.
The process is split into two steps:

After comsidering the fedback I got from the previous
'Massive scalability thread, I decided to split my queries
into two areas: Rack scalability and ZCatalog scalability.
This email deals with the former.
It seems clear that indexing and searching are more of a
botleneck than storage/retreival.

Do not allow direct queries to search the catalog. Instead, make

That would stop globbing searches for everyone.

Sorry, to be more explicit :
I built python 1.5.2 and Zope 2.2.2 from source, although the most recent

I did not use the ports distribution of python or zope, so I don't know if

Hi,
This problem started with failure to access Control_Panel, which I
thought was due to a SiteAccess problem... but I now tracked it to a

No reason except that I have an install script for python, zope, and modules

our production servers, whether linux, or freeBSD. I should try the ports

I'm creating variables in python but I am having trouble creating them
when they're *named* using other variables. Here's an example;

Hi Lee,
You could use a dictionary for this:
vars = {}
while (p!=0):
vars['p'+`p`] = string.replace(component[control], ",", "")
p=p-1
control=control+1
then 'vars' will contain keys (e.g., 'p1', 'p2' etc.. ) and corresponding values.
