Microsoft IIS 4.0 and Zope
by Petter Enholm 08 Dec '00

08 Dec '00

Hi, This may be more of a Microsoft IIS questions than Zope question, but I give it a shot! I have installed Zope (on port 8080) on a Windows NT 4.0 server with IIS 4.0, followed to Howto that explains how to set up PCGI with IIS, and all works very well. I can access Zope through http://localhost/scripts/zope.pcgi Next step: I want to access the Zope site through a given DNS name, f eks www.mydomain.com. How can I do this with IIS 4.0? I find no way to redirect a virtual host and at the same time rewrite the URL so that the user gets http://www.mydomain.com in the browser, not .../scripts/zope.pcgi. Anybody out there with knowledge on this issue? Best regards Petter Enholm Snapper as

Could it be that you don't derive your product class (directly or indirectly) from Acquisition.Implicit? Otherwise, I'm stumped. I use just the code you describe inside the PTK, for instance.

well, i installed navigator_demo.zexp and the ZNavigator folder from 2-00 and 2-01 respectively that i downloaded yesturday didn't help, but solution solution: delete navigator_demo/simple_demo/infobar/nonsens and simple_demo works your selection of objekt names, bar entries and the respective differences does unfortunately not really support bugtracking :-( since the complex_demo does not give any positive sign i give up here i would love to understand the complex_demo too, in case you have the correct version feel free to email it to me. thanks for your help and your product anyway olaf Jonas Juselius schrieb: > > Did you _install_ the code for ZNavigator 2.02 _and_ the examples in that > dist?

Hi! > i knew that! :) btw, there's currently sparse document on mod_pcgi2. i'd > like to change that, but i need info from you (the author ..straight from the > horses mouth - so to speak) or snippets from your httpd.conf. do i need to > have Zope.cgi available? i think i do since otherwise, there'll be no > connection. or am i missing something? You missed pcgi-wrapper :) If you look into Zope.cgi (it is just plain text file) you'd found it is a script interpreted by pcgi-wrapper. That very pcgi-wrapper is a binary file compiled from pcgi-wrapper.c during the Zope installation process. The pcgi-wrapper binary is the program that implements PCGI protocol. When I wrote mod_pcgi2, I borrowed a lot of code from pcgi-wrapper.c. That way you do not need Zope.cgi or pcgi-wrapper - the PCGI code is already in mod_pcgi2. > how can i finetune the performance? it seems that under heavy load, eg 100 > simultaneous apache connection, it'd get loger to contact the server. in the > browser, we'd see contacting the server, waiting for reply .. for about 3-4 > secs before we get any activity/reply from server. You'd need to finetune Zope, not the mod_pcgi2 module. When you connect to Zope-behind-Apache the process is going the following path: 1) browser sends a rquest to Apache 2) Apache invokes the mod_pcgi2 handler 3) the handler passes the request to Zope 4) !!! here is the problem to finetune !!! If Zope's own pull requests handlers is empty - Zope does not handle the request, but queues the request and waits 5) after Zope processes the request it passes the results back 6) mod_pcgi2 passes the results to Apache 7) Apache passess it back to browser. Ususally there are 4 threads in Zope, and 7 ZODB connections. The first number - 4 threads - could be configured by passing parameter to z2.py. If you raise the number much, you'd need to raise he seconf number somwhere in the ZODB source code. These are points for finetuning. Actually you may need to tune more things, but these things are just totally unrelated to mod_pcgi2. Tune ZODB cache, install and learn to use cacheing Products (the are a number of caches for Zope), use squid, etc. > when i do a packet dump, it seems that the machine needs a couple of SYN > before getting and ACK from the server. do you think it has anything to do > with mod_pcgi2? sorry if it's not. I'm pretty sure it has nothing with mod_pcgi2. SYN/ACK are properties of TCP/IP protocols, and PCGI protocol is much higher level.

I think you should do "Find Items to ZCatalog" and do a clean index of the whole website. Apparently "Update Catalog" doesn't touch the old invalid pointers in the index. Also, for Yihaw you must find object of all types otherwise it won't catalog the subclassed objects! The correct behaviour in 2.2 is with a preceeding '/'. || -----Original Message----- || From: Didier Georgieff [mailto:Didier.GEORGIEFF@agriculture.gouv.fr] || Sent: Friday, December 08, 2000 10:45 || To: soren.Roug(a)EEA.eu.int || Cc: zope(a)zope.org || Subject: Strange Catalog problem. || || || Hello, || || I'm using a modified (french, adding programatically and new || classes but || the ground features are untouched) Yihaw on 2.2.4 (linux). || || I've got a strange behaviours (YihawNews boxes don't show || the new items) || until i found that "old" (before upgrading to 2.2.2 + 2.2.4 || update) items on || the catalog don't start with "/" and the new ones does start || with "/". || || Reindexing gives me the same 2 categories and change nothing. || || I'm puzzled with : || * what is the "correct behaviour / or no / ? || * why reindexing doesn't homogenize the / ? || || The "new" items are now added programatically and the "old" || ones where || done thru Zope interface. || || And sometimes i still get a "problem uncataloging before || catalogging" || message on the Zope console. || || Am i missing some important change ? || Thanks in advance. || || || -- || Didier Georgieff || DDAF du Bas-Rhin - Cellule SIG || 2, rue des Mineurs 67070 Strasbourg Cedex || tél : 03.88.25.20.33 - fax : 03.88.25.20.01 || email : didier.georgieff(a)agriculture.gouv.fr || SIT du Bas-Rhin : http://www.bas-rhin.sit.gouv.fr || GéoWeb http://sertit10.u-strasbg.fr ||
