Use Cron to fire up a simply python script that uses ZClient to call the manage_pack or whatever method to pack the database. See lib/python/ZPublisher/Client.py for info on how to use ZClient. It's pretty simple: import Client x=Client.call('http://server.com/manage_whatever', username='superuser', password='bob') etc.... -Michel

You will, but only within each installation. Each time you start a new Python interpreter you'll get a new lock :-) This of course that you also have them all in separate object databases as well. > What I'm saying is if I *don't* use /usr/local/bin/python for my Zope > installations, but instead rely on ZOPE_HOME/bin/python, will I be > able to spread my Zope sites out over the four processors, or is > there a nasty sting in the tail in doing this? It has nothing to do with which Python you use, but instead that there are multiple Python's in multiple process spaces.

Your search form does not have have a bobobase_modification_time_usage hidden field. This tells ZCatalog you want to do a range search. Strange, because your first search form did have a usage field, perhaps you removed it? -Michel

You *allways* run into the interpreter lock.

Depends on the OS. some OSes will tend to prefer one process to one processor, and associate a cost with moving processes between processors, but threading may throw a wrench in that whole plan. Perhaps there is a a Solaris command to bind a process to one specific processor? -Michel

Creating a ZClass that subclasses document like behavior would be the 'Zopeish' way to do it. If what you have now works, it might not be worth changing, Zope can work with all kinds of data models. One of the benefits of using objects in the object database is that you can use the full text searching from Catalog, your relational database might not do that (or it might, who knows?). I would check out the ZClass tuturial, it can be found in the documentation section of the zope site. -Michel

Automated packing of ZopeDB
by Michael Schmeing 23 Nov '99

23 Nov '99

I am currently running one Zope server for a customer of ours and I am preparing to start several more. To save disk-space (as our customers pay for the space they use) the Zope database has to be packed on a daily basis. With the one Server we are hosting currently that has been no problem doing it manually but when the next sites are moved this can not be done manually any more. So my question is does anybody know how Zope databases (both version 1.x and 2.x) can be packed automatically? Any method running on Linux is OK by me, either inside Zope or cron-based or whatever.

Global Interpreter Lock and four processors...
by Tony McDonald 23 Nov '99

23 Nov '99

Hi all, We have a four processor Sun box (each processor scores about 2400 pystones, whereas a 500 MHz P3 gets about 5400 pystones). I have three zope installations running, one of which is hosting three subsites. If I create four *binary* installations of Zope (complete with the thread-safe MySQL adaptor and all the other python libraries necessary to run a Zope site), will I run into the global interpreter lock? What I'm saying is if I *don't* use /usr/local/bin/python for my Zope installations, but instead rely on ZOPE_HOME/bin/python, will I be able to spread my Zope sites out over the four processors, or is there a nasty sting in the tail in doing this? thanks in advance, tone. ------ Dr Tony McDonald, FMCC, Networked Learning Environments Project http://nle.ncl.ac.uk/ The Medical School, Newcastle University Tel: +44 191 222 5888 Fingerprint: 3450 876D FA41 B926 D3DD F8C3 F2D0 C3B9 8B38 18A2

Storing Content
by Markus Strickler 23 Nov '99

23 Nov '99

Hi! I'm planning to use Zope on a site that includes news article like content. Using PHP or whatever I would set up some relational table structures for the content and create display and edit scripts that query the database. I've tried this with Zope but was wondering if there is a more Zopeish way to do it. (Like creating a subclass of dtmldocument and adding my own display and edit methods). If so can you point me to some docs about this? I'm also wondering which wll be the best databse to use with Zope. I'm developing mostly on Windows but will deploy on Unix. I'd love to use Oracle, but as this is a 0-budget project, I can't afford the license fee. MySQL might be fine, but afak the Windows version is not freely available. Does anyone know about other crossplatform DBs that work well with Zope? Thanks, Markus
