Hi, it is true but only under Win32, or not? Under Linux I was make very heavy load tests, without no problem after changing network card (eepro100 was replaced by 3c900B) - old netcard (intel) totally crashes my Linux server. Under winNT2k I was able to shutoff or froze Zope within 1-3 minutes. Regards JL.

Disable inheriting from a class
by Jan Maška 04 Apr '03

04 Apr '03

Hello, How do I set a custom class (product) so that it is locked against inheriting? I mean, if I'm creating another custom product (ZClass), ZOPE allows me to import so-called Base Classes. I need to get my class off of the list, for some compatibilty and conflict issues. I did search for answer to this in documentation an on the web, but I didn't find any useful hints. Thanks in advance for your tips, -Mac =============================== Jan 'Mac' Maska, web developer Systinet, Prague(CZ) jan.maska(a)systinet.com tel.:(+420)608453492 visit http://www.systinet.com ===============================

manage_edit or manage_upload help
by Ravneet Sachar 04 Apr '03

04 Apr '03

Hi, I have created a file object from the OFSP product using manage_addFile. This works great. Now I am creating a form to edit the contents of the file. On submitting this form, I want the file data to be updated with what was there in the textarea of the form. Seems simple, and I tried to use manage_edit or manage_upload from my python script. I am unsuccessful in doing this and get Attribute Errors. I would appreciate it if someone could send some example code to help me update the contents of a file object. Thanks Ravneet

Re> another newbie rewrite problem
by Dan Donaldson 04 Apr '03

04 Apr '03

I got it working! Thanks for the prompt replies. I have to say that while the documentation for Zope can be -er - challenging, the quick response from the community is great to see. The problem was not having the proxy modules loaded. It would appear that Apache 2 has a more elaborate scheme for proxy modules, and the tutorial at www.zope.org/Members/ike/Apache2_freeBSD also helped, by alerting me to the proxy module loading order. This is what I added to the bottom of the LoadModule sequence: LoadModule proxy_module modules/mod_proxy.so LoadModule proxy_connect_module modules/mod_proxy_connect.so LoadModule proxy_ftp_module modules/mod_proxy_ftp.so LoadModule proxy_http_module modules/mod_proxy_http.so Eventually, my virtual host set up looked like this: NameVirtualHost 10.1.3.225 <VirtualHost 10.1.3.225> ServerName www.dantest.com ServerAlias dantest.com DocumentRoot /var/www/html RewriteEngine On RewriteLog /dan/rwLog2.txt #RewriteLogLevel 9 #RewriteCond %{HTTP:Authorization} ^/(.*) RewriteRule /Zope/(.*) http://10.1.3.225:8080/VirtualHostBase/http/%{HTTP_HOST}:80/dantest/$1 [L,P] </VirtualHost> The road ahead is clear....

Slight OT: My Zope is now powered by Linux
by Jaroslav Lukesh 04 Apr '03

04 Apr '03

Hi all, I was get last week from my chief separate machine to run Zope. Before Zope runs at Win2k Terminal server, dual Xeon 1Ghz, 1GB RAM, SCSI disks, intel server board. Now Zope runs from Linux Mandrake 9.1, Celeron 950MHz, 128MB RAM, one IDE disk with journaling XFS filesystem, intel non-server board with 3com netcard. Performance boost what I was get is 2-100 times better than from Windows machine. 2 times is for cataloging (text index), about 10x boost is for page rendering (DTML, STX) and about 100x better is for giving small images (buttons, 90-400 bytes size). Zope at Windows I was able to crash with 50 concurrent requests in time 2-3 minutes. Zope at Linux I was not able to make crash (with 3com netcard of course, with onboard intel it crash whole system!) - I was crash my local machine (win32, 300 concurrent requests) from where I was cyclically mirror my zope webs. So I was wery happy, my Zope runs as never before. Regards JL.

restrcting zope to a single processor on Solaris8 machine
by Tena Sakai 04 Apr '03

04 Apr '03

Hi folks, I am running zope on Solaris 8 (sparc, SF4800, 4 processor) machine. Recently, a major app was taken off this machine and I started to experience problems. The problem is that response time is exceedingly and unbearably slow. Having read a thing or two, I suspect this is to do with Global Interpreter Lock of python not being able to use multiple cpu's. I am trying to use psrset command to fix the problem, but so far unsuccessful. What I have done is to write a one-line shell script that says psrset -e 1 Path-to-Zope-Directory/start where 1 is a processor_set_id (created via "psrset -c" command) and this set uses strictly one processor. But the start script cannot finish execution. It complains as to permission denied for var/Z2.pid file.

Re: [Zope] Fwd: [Zope-DB] HEEELP! my zope has become virtually unusable
by Tena Sakai 03 Apr '03

Hello Toby, Thanks for your reply. I looked at those number after a restart and they now look like: Total number of objects in the database: 10585 Total number of objects in all caches: 355 Target Size: 400 Target max time between accesses: 60 I didn't know that top two numbers were dynamic. Since the balance has changed, I'd like to leave them alone for now.

If you have the default 4 threads (and assuming you are not using versions) then it is interesting to note that 2294 is much bigger than 4*400 That indicates you have memory pressure. This might be the cause of your problem. If so, you could try: * doubling the target size, and perhaps halving the number of threads. * upgrading to 2.6. the cache manager was rewritten and is much better behaved. -- Toby Dickenson http://www.geminidataloggers.com/people/tdickenson
