Installing new objects
by Alexander S Coventry 14 May '00

14 May '00

Hi. What does it mean when a newly installed object fails to show up in the "Available Objects" list of the Zope Contents page? I have been trying to install Ken Manheimer's Tracker. I put the TrackerBase object in the lib/python/Products, copied Tracker.zexp to the import directory, made a symlink from Extensions/TrackerMethods.py to lib/python/Products/TrackerBase/TrackerMethods.py, and restarted zope. The TrackerBase object does not show up in the "Available Objects" list, and attempting to import Tracker.zexp gives the error "The object Tracker does not support this operation" along with an uninformative-looking backtrace. On the other hand, the TrackerBase did turn up when I did a "Find." Any advisce on where I should go from here? Alex.

Re: [Zope] strategies for starting zope on redhat
by Felipe E. Barousse 14 May '00

14 May '00

I am experiencing exactly the same behavior on several Red Hat machines (6.1). I have noticed in one machine that when Zope is started from boot, it uses a pcgi.so socket file located at /usr/local/Zope/var Later on, when started from shell, it seems NOT to use that file and operate ona different mode. The messages I get when I try to update a PostgreSQL db when Zope was started at boot are "Document contained no data"....This doe not happen with a shell started Zope. Are you or your friend experiencing something similar ? Well, if I get to fond something to solve this, I'll let you know. Regards.

Nope, didn't try against 7.0. Based on other things I've read, I think you can make it work, so long as you're not using any 7.0 features.

Zope's scalability across multiple web servers
by Bostick, Aaron 14 May '00

14 May '00

I am in the process of designing a web site that will handle the load of a nationally advertised web site. I am considering using Zope over Pervavsive's Tango2000 or Vignette's StoryServer as an application server. What I would like to know is if there are any easy ways to replicate the ZODB information across web servers if I am running a web farm? In other words, I plan to have multiple identical web servers sitting behind a load balancing appliance so that incoming requests can be sent to any of the web servers. Obviously, the web servers must contain the same data for this to be of any use. If I plan to run a web server and the zope engine on each "web server", how can i replicate changes to all my servers to keep them synced. Would something as simple as a recursive copy work for this? This is not something that will have to be done in real time. Something simple like a batch job would suffice. Other than the database content, the HTML stuff will remain relatively static. Please excuse my ignorance on Zope. I haven't had the chance to set it up yet and am still in a preliminary design phase. Thanks for any helpful hints regarding this matter!

Crashing due to pcgi after system boot
by Felipe E. Barousse 14 May '00

14 May '00

Whenever Zope is started automatically from the rc3.d scripts, it appears to me that is starts in a "mode" that uses pcgi.so (pcgi socket mode...?). By some reason, my application fails in this mode, specially when UPDATING records on the PostgreSQL database (not when creating or deleting records). After some attempts, Zope crashes and the process dissapear from the "ps aux" table. If I delete the pcgi.so and pcgi.pid (from the /usr/local/Zope/var directory), and re-start Zope (logged as nobody) and using the usual "start" command. Everything works fine. In other words, Zope behaves strange when started automatically at boot time. Question is: Does any of you knows how to get rid of this pcgi.so using mode at system startup. ? Where did I miss some configuration ? Any extra comments are very welcome. Thanks in advance and regards. Felipe Barousse

Hi Phil! Please don't send HTML formatted mail to the list. Some people on the list use mailers that don't take too well to it. Sorry for that. I was simply inattentive. :-| >You need to put the files you talk about into a directory under your zope >directory: > ><zopedir>/lib/python/Products/Boring. > >Create this and then put the files in there > >Then you'll have to restart Zope to get it to recognize them. > I have done it and Zope recognized the product. However there are 3 DTML files in the source and I'm not sure what to do with them. Could you give me a hint? About ZEXPs: I was trying to find a technic that would allow me to transfer my product between different Zope installations. What i did was copying "VAR" folder and exporting product with the help of Zope's Import/Export menu. But when I tried to the reverse procedure to import the product into a different Zope installation performing the same steps (copied "VAR" and tried to import .ZEXP file), I failed. I can't figure out what was wrong. Do you have any suggestions? > HTH Thanx, it really did :) Lena

Manila anyone?
by Jason Cunliffe 13 May '00

13 May '00

Hello Zopisti I have been looking with a lot of respect at Manila lately... http://manila.userland.com/ I really like the web sites people are making with it. - good *clean* design - interesting content - obviously a tool which encourages people to use it on daily basis I refer to the weblogs / editthispage idea http://www.weblogs.com/about The most famous around here is of course http://weblogs.userland.com/zopeNewbies/ Q1. What are the lessons and inspirations for Zope community ? Q2. How do you see the two platforms working together ? Q3. Why does DC not hire a decent graphic designer ? <flame-retardant-socks+glasses:ON> Zope is potent intelligent cutting-edge software, but it 'looks and feels' [literally/visually] like it came from from the Alfred.E.Newman-School-of 'What-me-worry-about-Design?-that's-just-for-pretty-boys! - we'll fix later'. Wake up folks - please = Later is now.. </flame-retardant-socks+glasses:OFF> - Jason ________________________________________________________________ Jason CUNLIFFE = NOMADICS.(Interactive Art and Technology).Design Director
