Folks - Federico sent me a patch for the popy-1.3.3 source. I needed it to tell it where the postgresql libraries are..if you need it please let me know and I will send it along. You may also find it in the archives from earlier this month. - Steve On Fri, 11 August 2000, "Hung Jung Lu" wrote: > > --- In zope(a)egroups.com, ed colmar <element@i...> wrote: > >Hi, I downloaded the current versions of ZPoPyDA, and PoPy from > >www.mixadlive.com, and I cannot figure out how to execute the installation. > > Run the autogen.sh script first, instead of the ./configure. > > Could you send an e-mail to Eric (one of the authors) eric(a)mixadlive.com?

Broken Links and Orphan Checking
by Darin Lee 11 Aug '00

11 Aug '00

Greetings, Is there any way within Zope to parse HTML to look for broken links and orphaned files? The site I am building will have many Zope dynamic componants, but also a good share of wrapped static HTML pages maintained by content contributors in Frontpage/Dreamweaver. I know that orphaned files and broken links *will* become a problem over time. Does anyone know of a good way to handle this? Thanks, -Darin M. Lee Darin M.

need some basic help
by Dan Huston 11 Aug '00

11 Aug '00

Hello Folks, So I downloaded Zope and installed it on my sun box and on my nt box. I can go to the manage page as the admin and it all looks like it installed fine. So I tried to create a folder but the superuser cannot own a folder it says. So I figure I can create a folder in the zope dir as one of the users I have defined, but then how do I add objects to that folder? The only login that works at the manage page is the admin password. Is there a different page for users to go to that is similar to the manage page? I can believe that the admin would have to add all of the objects as that would seem un-Zope-ish. I have looked at a lot of docs but they were either so basic as not to address hands on stuff (devshed) or advanced enough that it was assumed that you could do this simple task. Can someone straighten me out? Thanks, Dan

Yes, it's the pool_size parameter. You can increment this value *carefully* if you see that you have more threads hanging around than DB connections, like you're seeing now. I have no idea what this will do to your relational stuff. The "right thing to do" is to test this outside of production. I don't want to tell you to go ahead and muck around on a production server. But if it were *me*, I might be tempted to: - First, lower the number of threads via -t8 and see what effect that has on speed. - If that doesn't solve anything, bump up both the NUMBER_OF_THREADS and the pool_size up to 10 or 12, then do some checking, and see if you still have threads waiting for a DB. Continue doing this in increments of 2 or 4, making notes as you go. Note that if it breaks your site, I'll deny I ever gave you this advice. :-) Proceed at your own risk. > i love zope, and open source in general, and i can't bear > having to switch to > using something i don't really like. Geez, I hope not. This is an eminently solveable problem.

RE: [Zope] Defining High Load in Heavily DB Driven site (was: [Z ope] zope2.2.0 and what is high load)
by Jens Vagelpohl 11 Aug '00

hi dario, to clear up some possible misunderstandings and naming issues: we have two different beasts here. one is the number of threads that zope uses while it runs. this can be tweaked by invoking the start script with an argument like "t <number_of_threads>" or by editing z2.py and changing the default number of 4 threads. again, these are application threads. the database connections that were talked about are a different issue. these refer to the number of connections zope creates to its underlying ZODB object store. you can see them if you go to <myzope>/Control_Panel/manage_debug in Zope < 2.2.0 or by using the link in the control panel in Zope > 2.2.0. the number of these connections is set in <zope>/lib/python/ZODB/DB.py and the default is 7. in general, when a thread attempts to do anything with zope it needs to get hold of a ZODB connection so it can read or otherwise manipulate objects in the ZODB. this is why the number of application threads should be smaller than the number of ZODB connections. tweaking these numbers is possible, but mileage may vary depending on your specific site and usage. jens ---- Jens Vagelpohl jens(a)digicool.com Software Engineer www.digicool.com Digital Creations (888) 344-4332 Got Zope? ---- > -----Original Message----- > From: zope-admin(a)zope.org [mailto:zope-admin@zope.org]On > Behalf Of Dario > Lopez-Kästen > Sent: Friday, August 11, 2000 07:10 > To: zope(a)zope.org > Subject: [Zope] Defining High Load in Heavily DB Driven site (was: > [Zope] zope2.2.0 and what is high load) > > > Hello! > > I need to find more info on how Zope handles threading with > relation to > database connections. > > I am currently considering and evaluating Zope as one of the > options we have > to build a really large, completely databasedriven "enterprise scale" > web-platform.

Speeding up Zope by disabling logging of hits
by David Trudgett 11 Aug '00

11 Aug '00

I'm using zope behind a front-end server and don't require any logging of hits. Is there a way to disable Zserver hit logging to increase speed and decrease disk utilisation? (I suppose I can send output to /dev/null, but that doesn't stop the logging code from being executed, and I would also lose error logging.) Even better would be the ability to disable logging based on IP address of the requester. Thanks. David Trudgett
