- Zope - Zope lists

Another strategy question
by Robert Leftwich 29 Apr '99

29 Apr '99

On the subject of strategies, thanks for the replies to delivering version upgrades, but here is another one - What is the best strategy to use in maintaining the referential integrity of the object database ? For example, if I have a contact list and an appointment list which needs to reference one or more contacts for each appointment and I delete a contact, I then need to delete all the appointments that referred to the contact. Is there any low level support for this kind of problem or does it need to be built into the app ? Also, are there any notification functions called when a Folder is modified (i.e. items added or deleted) ? Thanks Robert Leftwich PS The answers to this type of question could live in a "Zope Idiom" section in the documentation and web site. (I almost said pattern, but idiom is more accurate), what do you think ?

PCGI/Zope instabilities.
by John Eikenberry 29 Apr '99

29 Apr '99

Hello, We are using Zope for some of the functionality on a high traffic (150K hits a day) site we maintain. It's turning out to be very unstable (on our platform at least). I'd like some advice on how to get it more stable (besides switching hardware/platforms, which is on the agenda down the road). What happens is that somehow a bunch of additional pcgi_publisher.py processes get started until eventually the zope app is unreachable ("Temporarily Unavailable" errors). I've seen up to around 10 of these additional python processes running at the same time. To get things going again, I have to login and kill them all and restart Zope (by reloading it - I have to do this about once every day or two). In the pcgi.log file, I find a ton of these messages: Thu Apr 29 11:02:57 1999 pcgi-wrapper: pcgiVerifyProc failed (103) unable to verify if process is running I'm guessing that mabey the zope process isn't returing fast enough for the pcgi process, which then thinks it needs to start up zope. Or something like this. My initial idea is to modify pcgi's timeout, to see if making it a little longer would help. Please feel free with any advice/tips/etc. Thanks, PS. some specs: Zope-1.10.2 Apache-1.3.3 BSDI 3.1 (strange setup with multiple virtual machines on one physical machine - they claim it's no different than a full system) python-1.5.1 (all modules are statically compiled in - including zope modules) --- John Eikenberry [jae(a)kavi.com - http://taos.kavi.com/~jae/] ______________________________________________________________ "A society that will trade a little liberty for a little order will deserve neither and lose both." --B.

Presumably we should stop Zope before adjusting the system clock? (moving it back, if not forwards).

Hi, We've the following schema (see article : 'What is Zope?') : Web browser ! Zope Publisher ! Zope ORB Then... Module and inside the module we've the Object and Template Can I say that ZFramework is the same as the Object module or where do I've to situate this? Or there more then 1 Object modules? Are the object and modules not retrieved from the Object database? Tom.
