system down - how to prevent?
by Roel Van den Bergh 05 Mar '03

Hi all. We have been working with Zope for over a year now and we like it. It has been a long time since I had to call upon you people to help me out. Yesterday, our production server went down the hard way. While someone was editing some objects in the ZMI everything crashed. Not only Zope, but the entire machine. We are running redhat 7.3, apache and Zope 2.5.1 + CMF 1.3 on a Dell PowerApp 120 dual PIII 1Ghz, 1 GB ram, Raid 5 so we thought we would be rather save having also backed up Data.fs by our hosting provider. After the crash the server would not start up again, indicating 'memory failure'. After several retries nothing works anymore. The machine is still under warranty so there is no real problem either. Now comes the funny part. There doesn't seem to exist any backup of the Data.fs. Checking our systemlogs prior tho the incident revealed this: Feb 14 02:54:08 piwebserver Retrospect[27997]: FSGetNodeInfo: lstat failed on "/home/zope/2-5-1/var/Data.fs", error 75 Feb 14 02:54:08 piwebserver Retrospect[27997]: FSGetNodeInfo: lstat failed on "/home/zope/2-5-1/var/Data.fs.old", error 75 Feb 14 02:54:12 piwebserver Retrospect[27995]: connTcpConnection: invalid code found: 111 Now they tell us their backup program can connect to our server, but the Data.fs file cannot be backed up because it is locked / in use. Our firewall is open to the backup program $IPT -A tcp_inbound -p TCP -s 111.111.111.111 --destination-port 497 -j ACCEPT How come? We can manually create a copy of the file. Has anyone had these problems and how did you solve them. Secondly we are investigating how to prevent downtime of the production server in the future. I had a quick peek at ZEO but I'm a bit lost there. What is the minimum setup for a production site to be kept alive (not necesaraly with the same specs) As far as I can tell you need at least three machines to keep your site alive: a 'load- balancer', a 'client' and a 'server'. Could this be narrowed down to two machines? And what if the actual 'ZEO server' goes down? TIA, WKR, Roel

Newbie question about installing modules
by Chris de Boer 05 Mar '03

05 Mar '03

Hi there, I've just installed Zope and Plone and I'm trying to install additional modules (like the VisualEditor module). It has to be copied to the lib/Python/Products directory. When restarting the zope server, it generates an error. I couldn't find any documentation about how to install the module (other than: "install in the normal way"). I suppose I have to run some kind of script to install the module properly. Any help will be appreciated !!!!!!! Chris.

Result set error
by Zope＠Stylus 05 Mar '03

05 Mar '03

Hi all I am using Zope-2.5.1 on a Mandrake Linux machine .My RDBMS is PostgreSQL. I have written a simple python script which calls a zsql method whicg returns a ResultSet which has 5000 Records. Now I am readig from the ResultSet and writing the values to an array (tuple) . But of the 5000 records I am being able to get only 1000 Records in the Pytho script .The 4000 other records dont seem to be coming . Here is my code. userlist = [] list_users = context.oms_old.john.db.zsqll_omslogs() print len(list_users.tuples()) #----> the answer I get is 1000. for x in list_users: userlist = userlist + [[str(x[0]) , x[1], str(x[2]) ,str(x[3])]] #return userlist return printed So now I am getting a tuple with just 1000 * 4 array Where I should be getting a 5000 * 4 array .. The zsql method -->context.oms_old.john.db.zsqll_omslogs() --- is as follows select * from omslogs And select count(*) from omslogs returns 5000.But the answer for len(list_users.tuples()) is 1000. Also I am geeting only the 1000 Records in the table where I am displaying the records. Could you please guide me here and point out where I may have gone wrong.Thanks for all help in advance Thanks and Best Regards John Kunchandy --- Outgoing mail is certified Virus Free.

Users and passwords
by Yannis Lionis 05 Mar '03

05 Mar '03

Hi everyone. I have a problem with creating and accessing a new user. If I create a new user in the acl_users folder (login name: guest, password: guest) and then logout and try to login as guest, the password is not recognised. I took a look around the mailing list archives and discovered that others have been having the same problem, but I found no solution that works for me. But what _really_ worries me, is that when I add the new user and then try to edit its details, the password is (or looks) 8 characters long no matter what password I had entered! Is this normal behaviour? Can anybody help me on this? Thanks! Yannis --------------------------------- Do you Yahoo!? Yahoo! Tax Center - forms, calculators, tips, and more

Re: [Zope] STX - how to add new function

I doubt there's a : how-to for modifying these files in exactly the way you want to, but if you : put up what you're trying and what's going wrong, you can probably get some : help. Thanks for a promise and sorry for long mail. In attachment I send my changes, here are errors, filenames and added/modified lines only in STX_changes.stx. I know that would be better to write new .py scripts, like Document/HTMLWithImages.py, but I dont know exactly how, I am not a big programmer. Many thanks, J. Lukesh

zope access to external files
by Ricardo Anguiano 05 Mar '03

05 Mar '03

Greetings All, Some stats on my (stale, and soon to be updated) setup: Zope Version (Zope 2.4.1 (binary release, python 2.1, linux2-x86), python 2.1.0, linux2) Python Version 2.1 (#2, Jun 22 2001, 10:20:42) [GCC 2.7.2.3] System Platform linux2 I have a couple of objectives: 1. I want to restrict file access by user. 2. I want to serve objects from zope to accomplish objective #1 above, but I want the objects to be in the filesystem. I want to be able to say, "The contents of directory X are available only to user Y." I looked through the list of products in the "External Access" category and there were a couple of good candidates. The localfs listing was hard to find but it did turn up in a faq somewhere. http://www.zope.org/Members/arielpartners/ExternalFile http://www.zope.org/Members/MacGregor/ExtFile http://sourceforge.net/projects/localfs Questions: Can anyone recommend one of these products over the other? Will they let me do what I describe? Are there products which are a better fit? Is there an easier/better way? My apologies if this has been answered in the mailing list recently. An archives search did not turn up anything. Thanks in advance, -- Ricardo Anguiano http://www.codesourcery.com

>It doesn't need to be named. Call your python script via the dtml-in, return >foo, and all will be well. I do it all the time. But what I want to do is the opposite: to call the dtml-method from the python script with the list as an argument.

That's terribly unlikely to be blocked. I'm assuming you can see that the Python processes are running: if so, perhaps you can try the scripting-Zope-by-ZEO method to see if anything actually is happening. And do you get anything by way of log activity or console output ? (assuming this Windows Server thingy has a console...) --jcc

I'm locked, I can't change anything I modified in a "experimental" version and of course I was not very cautious in my experimentations..
