hello, i remember reading on the zope site that there was a #zope channel set up on efnet... i have been periodically checking there, but no one seems to be logged on there.. i am in no way stepping on any ones toes here, but for simplicity sake, i did put a bot in the channel, to keep it alive (topic set, etc.) i will gladly remove the bot to the proper owner, i just thought it would a cool place to meet fellow zope'rs... -Samir

RE: [Zope] Performance of webserver?
by Thaxter, Jason M. 01 Sep '99

01 Sep '99

YMMV: I've been working on benchmarking myself (freebsd/apache/pcgi/zope) and noticed this: ./start script uses the -D option. I was noting rather high CPU usage. I shut down Zope and restarted it with python z2.py -p/path/to/Zope.cgi and got better results. This allows the python process to detach from the terminal, since -D is debugging mode. While many benchmarking stats are meaningless, I can support Amos' basic contention that zerver is about 4x faster that apache/pcgi/zerver. > -----Original Message----- > From: Andreas Kostyrka [mailto:andreas@mtg.co.at] > Sent: Tuesday, August 31, 1999 3:10 PM > To: zope(a)zope.org > Cc: Zope-l > Subject: Re: [Zope] Performance of webserver? > > > On Tue, 31 Aug 1999, Itamar Shtull-Trauring wrote: > > > Christopher Petrilli wrote: > > > > > Performance on a "mid size" Linux box would > > > be 35-50 hits/second (which translates to 3.8M hits/day). > > > > Is this using ZServer or PCGI via Apache? > Well, I just benchmarked a simple Zope page (http://www.mtg.co.at/) > locally.

I've been playing with the same = <dtml-if column1> <dtml-var column1 null=""><BR> </dtml-if> This also displays NULL ! Which means both the dtml-if and the default null value are failing to recognise the null value in my variable 'column1'.

sql.error with ODBC on IIS 4.0
by Jim Sanford 01 Sep '99

01 Sep '99

Have been setting up and testing a project on a Win 95 machine using Zope's built in server. (Zope version 1.10.3). Have built several queries which have been working fine. Since the bosses liked our prototype it is now on fron burner. Have installed Zope on NT 4.0 machine with IIS 4.0 as the server. Can get to the management screen but when I try to test my SQL methods all I get is a generic sql.error (traceback is below) The ODBC connectors connect and disconnect fine. Even a simple "select * from names where id = 27000" gets the sql.error. Can anyone help? Traceback <html> <head> <title>sql.error</title> </head> <body> Sorry, an error occurred.<p>  </body> </html>

How to create a trigger?
by Fredrick Rybarczyk - LUB NetLab 01 Sep '99

01 Sep '99

Hi, Sorry for this newbie question. Hope anyone has the time to help me out. I would like to do something like this within a dtml document that has a property: int my_property = 0 <dtml-if "my_property==0"> <a href= .. ???>press this to show some content</a> <dtml-else> <a href= .. ???>press this to hide some content</a> <dtml-/if> ... a bit down in the document <dtml-if "my_property>0"> show some content <dtml-/if> ...or in plain words. I want to set the value of a property ( or variable if that would serve me better ) whenever I click on a link. Can someone please show how to do it? Thanks -- ========================================== Fredrick Rybarczyk Research Engineer NetLab, Lund University
