These are all very different and not really comparable in a simple (ie brief) way. I suggest you go to http://www.w3.org to read up on what XML and DHTML are, and go to http://www.zope.org to find out about DTML. There is also a good (better in my opinion) alternative to DTML for Zope now, called ZPT. This is XML-based and generally more structured and clean. If you're just starting out with Zope I strongly recommend you use as it will (hopefully) prevent you from falling into any of the many possible problems you can get into design-wise with DTML. It's much harder to write bad code (IMO) with ZPT. Harry
I am really keen to learn ZPT. I am having trouble unlearning DTML. Can someone point me to some good doco for some who is DTML damaged?

I've just discovered daemontools (http://cr.yp.to/daemontools.html) thanks to a very helpful chap on CLP. I used to have so much trouble with Zope crashing that I ended up running cronjobs to check if Zope was running and restart it if not. How I wish I'd known about daemontools back then! Anyway, much as I believe that Zope is much more stable nowadays, I'd still like to run it under daemontools "just in case". The only other references to using daemontools with zope are 2 years old. http://www.zope.org/SiteIndex/search?text_content=daemontools Has anybody here been using zope with daemontools for quite a long time ? or at least with Zope 2.4.x or 2.5.x ? Does it require a special 'run' script for the service, or could I simply use "exec /var/zope/start" ? Stephen. -- GMX - Die Kommunikationsplattform im Internet. http://www.gmx.net

Hi, I am running Zope under daemontools under versions up 2.5.1, my run-script looks like this: #! /bin/sh exec 2>&1 PATH=$PATH:/usr/local/bin ZOPE_HOME=/usr/local/ZopePark/lzope.aixtraware.de export ZOPE_HOME INSTANCE_HOME=$ZOPE_HOME/ZInstanceHome export INSTANCE_HOME PYTHONHOME=$ZOPE_HOME/ZSoftwareHome export PYTHONHOME exec setuidgid lzope $PYTHONHOME/bin/python $PYTHONHOME/z2.py \ -D -p - -P "10.2.1.4:8900" -t 2 -Z ''\ "$@" >> $INSTANCE_HOME/var/z2.log 2>&1 I hope that helps. --On Mittwoch, März 06, 2002 22:05:11 +0100 Shriek@gmx.co.uk wrote:

Thank you very much. Find it strange that anybody running Zope under daemontools seems to create a large 'run' script instead of just letting daemontools run the 'start' script that comes with Zope. Guess it's just a question of taste and no real reason for it though. Thanks again, Stephen.
I am running Zope under daemontools under versions up 2.5.1, my run-script
looks like this:
#! /bin/sh exec 2>&1 PATH=$PATH:/usr/local/bin ZOPE_HOME=/usr/local/ZopePark/lzope.aixtraware.de export ZOPE_HOME INSTANCE_HOME=$ZOPE_HOME/ZInstanceHome export INSTANCE_HOME PYTHONHOME=$ZOPE_HOME/ZSoftwareHome export PYTHONHOME exec setuidgid lzope $PYTHONHOME/bin/python $PYTHONHOME/z2.py \ -D -p - -P "10.2.1.4:8900" -t 2 -Z ''\ "$@" >> $INSTANCE_HOME/var/z2.log 2>&1
I hope that helps.

Maybe because the start script is made for the simplest case only? Also I find it better to see all in one place that affects the start of a service. If you use two scripts you have to watch two scripts.

Wow, 2 years now. But still valid - we use this setup all time.
Has anybody here been using zope with daemontools for quite a long time ? or at least with Zope 2.4.x or 2.5.x ? Does it require a special 'run' script for the service, or could I simply use "exec /var/zope/start" ?

DTML defines new tags to be replaced by text inside page templates.
