Urgent: ZODB transaction error '_p_oid' attribute
by felix slager 06 May '03

06 May '03

Hi everybody, i have a serious problem using Zope to run an administrative form for lots (and lots) of students. I get lots of ZODB conflict errors and crashes of the zope instance (2.6.1. linux) with the following beauty: 2003-05-06T10:12:05 ERROR(200) ZODB A storage error occured during transaction abort. This shouldn't happen. Traceback (innermost last): File /usr/local/zope/Zope-2.6.1-src/lib/python/ZODB/Transaction.py, line 261, in commit File /usr/local/zope/Zope-2.6.1-src/lib/python/ZODB/Transaction.py, line 392, in _commit_error AttributeError: Surrogate instance has no attribute '_p_oid' A restart of the instance is needed, but it's thin ice. I've found, and was send (:-) some leads in lists about this problem. It appears the problem is caused by the transaction mechanism (there's no _p_oid in the classes of the DA). Does anybody know a (quick) fix to this problem. Help would be very (VERY) welcome indeed.

40,000 users - 800,000 documents
by Robert Jean 06 May '03

06 May '03

Hello, We are seeking information on running Zope under an extreme load. Here are the metrics of the system that we would like to migrate: # of users with an account: 40,000 # of R/O concurrent users at peak time: 5,000 # of R/W concurrent users at peak time: 5,000 # of (static) documents: 800,000 Read-only users mostly search and view documents. Searching is currently done with metadata, but we would like to add full-text search on text renditions of the documents. Read-write users mostly view and index documents. --> Has someone already run Zope under such extreme conditions? --> Could someone share ideas on hardware and software issues? We plan to do some kind of feasibility testing. At this time, here are a few of our ideas: 1. Run ZEO 2. Possibly add an additional layer of load-balancing with specialized Linux software 3. Serve static pages with Apache or IIS 4. Do not rely on ZODB only � consider MySQL, Postgres, Oracle 5. Consider alternatives to ZCatalog � for example Lucene 6. Develop customization with Products instead of ZClasses 7. Use Zope RAM caching as much as possible Your opinion on this topic will be very much appreciated.

Using Pound
by Dennis Allison 05 May '03

05 May '03

Pound (current version) looks like the right choice for our particular application. I planning out the system I have stumbled on a couple of problems where I need some help.B I have Pound working. I encountered one minor problem--the code claims the configuration director is found in /usr/local/etc/pound.cfg whereas some of the documentation suggests it is to be found in /usr/local/etc/pound/pound.cfg Pound maps an incoming request to a (IP address, Port) based upon the host name. In my particular case, I want to run multiple instances of Zope (say, 127.0.0.1:8080 and 127.0.0.1:9080) remapped from, say, alpha.mydomain.com and beta.mydomain.com. What magic does one use to convince Zope to use the appropriate domain name when it generates an absolute URL?

Combining hits from searching 2 ZCatalogs at once
by Gordon Lai 05 May '03

05 May '03

Hi, I'm writing a Python script that searches 2 ZCatalogs at once with a form-provided query. The first ZCat contains scanned images of text documents plus their metadata. The second ZCat contains the OCR text of the same documents. The searches are written like this: textresults = context.Text_Catalog( {'PrincipiaSearchSource': query} ) ocrresults = context.OCR_Catalog( {'PrincipiaSearchSource': query} ) Text_Catalog is the primary catalog; it contains more metadata than in OCR_Catalog and hits on this catalog are preferred. OCR_Catalog is the secondary catalog; if I get a hit here (and assuming there's no hit on its matching document in Text_Catalog), then I want to find its matching document and add its metadata to textresults as a new hit. I'll then return the modified textresults to the calling form. My question is: How do I add the new hit to textresults? I tried textresults.append( newhit ), but I found out that textresults isn't a sequence, it's a LazyCat class instance. How do I append new items to this instance?

RE: [Zope] using zope behind IIS?
by Kelley, Sean 05 May '03

05 May '03

Thanks Sergio This works just great except for one little thing I have not figured out: When setting security in zope on an object in a folder, I then access the page through the IIS server and it prompts me to log in to that windows server instead of Zope. If I access the zope server page directly via zope I get a zope login box and all works. The zope through IIS works fine on pages with anonymous allowed. I am using zope 2.5.1, IIS on Windows 2000, and my client is IE 6 on windows XP. The zope server and IIS server are 2 different boxes. Any ideas on how to use Zope security through the IIS? thanks Sean -----Original Message----- From: Sergio [mailto:sergiomailbr@yahoo.com.br] Sent: Monday, May 05, 2003 11:56 AM To: Kelley, Sean Subject: Re: [Zope] using zope behind IIS?--help with IS dept.

oops, commit error ZODB (what's this)?
by felix slager 05 May '03

05 May '03

Hi dear Zopelist :-), i've been making a nice form for some administrative job. I've used Zope261 on linux, using products like exUserFolder, replaced it later with mysqlUserFolder, ZMySQLDA, CookieCrumbler and it's nothing fancy. I've written some processing python in a script and gave students access so they could practise using the interface. Repeatedly over the past days my Zope instance has vanished (or stopped, crashed) with some peculiar stupid.log entries: 2003-05-03T14:37:58 ERROR(200) ZODB A storage error occured during transaction abort. This shouldn't happen. Traceback (innermost last): File /usr/local/zope/Zope-2.6.1-src/lib/python/ZODB/Transaction.py, line 261, in commit File /usr/local/zope/Zope-2.6.1-src/lib/python/ZODB/Transaction.py, line 392, in _commit_error AttributeError: Surrogate instance has no attribute '_p_oid' I do not know what this might mean, but i'm curious - or should i say worried :). At first i thought this might be a problem using exUserFolder (with Radius remote authentication of users) so i replaced it (i read somewhere a discussion about commit errors and ZMySQLDA interfering with exUserFolder - or so it seemed). But still these problems kept appearing. So, i'm wondering, might this be caused because my script isn't threadsafe (whatever that might mean)? Is this a common error? Can anyone please enlighten me?

Hi, You will need to set up "User defined roles" under the security tab. Once the hyperlink is activated, the user will be prompted for user name and password. http://intranet:8080/file.htm -----Original Message----- From: Kelley, Sean [mailto:SKelley@ci.santa-rosa.ca.us] Sent: Monday, May 05, 2003 2:44 PM To: 'zope(a)zope.org' Subject: [Zope] using zope behind IIS?--help with IS dept. Hi, I am running zope 2.5 with the Zope server for my intranet. The company web (public) server is windows/IIS5. I want to use my zope server to provide some pages for the public on my zope server. Problem: IIS needs a physical folder to create a virtual directory in IIS. Zope does not have Windows directories that coincide with the folders that IIS/Windows needs. My IS department does not want to make my Zope server totally open on port 80 (because there are other internal items there as well). How can I securely serve a portion of my zope site within a windows/IIS network that does not require my entire internal/zope server to be totally accessible to everyone? _______________________________________________ Zope maillist - Zope(a)zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
