shot my acl foot...

I made a big mistake. I added a ZWikki product, then when I created the Zwikki web application, I went into the folder it created an uncheck all the acl permissions.. Okay -- I should rtfm... but I was in a hurry. Now, I can't do anything with it -- not even delete the folder. Is there anyway to overide everything and erase the folder and start again? I had not done anything it after initial creation so I suppose and could just leave it there -- but I really want it gone. -- David Bear College of Public Programs/ASU 480-965-8257 ...the way is like water, going where nobody wants it to go

Hi, I have a strange problem that I thought someone out there knows the answer. In my pilot, using Zope technology, I have been able to create a simple search engine for our company. Since I have no money (yet) for this project. I used MS Access as my DB. Mainly so the users can use the reporting tools. Each search was place in it's own table, to make thing easier for me. Everyone like what they saw but it also got them thinking and the decision was made to combine the tables into one. Now I was dealing with test data and I would take the excel spreadsheets and import them into Access. This worked, the users could see the data from one interface. Again, I was asked to add our New Part Numbering data into this one table. Again the spreadsheet was imported and I have a total of 3000 records (stop laughing). My problem is Zope can not see the part number information. Using Z SQL Method, I can view all the old data but no part number information. I can see everything in Access but not through Zope. To make things worst for me, before this last decision was made, I had written an Zope interface to the Part Numbering system. At the time I had 1500 part numbers that was imported (excel) into Access and I was able to view the information as well as add new records. I wrote this because I found duplicate part numbers under their filtered spreadsheet method. I have tried several different ways to import the information but I still hit the same brick wall, Any thoughts?? Larry McDonnell Proton Energy Systems 50 Inwood Rd.

Unexplained restart on add
by Terry Hancock 12 Jul '02

12 Jul '02

Hi All, By design, I have my development server and production server running the same version of Python and Zope. However, when I tried to install my newly developed product on the production server, I ran into problems, despite the fact that I have practiced this several times now on the development server which you would think would be pretty much the same. The problem is that, although the product shows up in the product control panel okay, attempting to add the main object from the product into a folder causes the server to restart (some of the lesser objects defined by my product will add without problems). To make matters worse, it does this without any kind of explanation: no traceback, no log messages (other than the normal shutdown and restart messages -- which proves it *is* logging events). The browser just reports a "refused" error message and visiting the control panel shows a short time since the last restart, indicating that it restarted. The events log shows the regular shutdown and restart events -- exactly as if I had clicked on the restart button in the control panel. It's really pretty infuriating! Also, frankly I don't know how they get it to restart on failures, anyway. My development server doesn't do that -- I occasionally get hangs or crashes, but never restarts. Obviously that would be a nice thing to be able to do in a production setting, but I don't understand how the magic works. There are, of course, lots of little differences: * I'm running Debian Linux and they are running FreeBSD (I think), though both are Intel architecture and the packages are installed from source. (I'm not using the Debian Zope package, but one downloaded from www.zope.org) * I run Zope as a special user, while they have it starting as "root" (which means it should run as "nobody" IIRC). * I use the default file-storage, whereas they run ZEO to separate the storage process (I think it still uses file-storage, but from ZEO). They claim this is faster even though the site isn't replicated. * There are some products in their Zope install that aren't in mine -- a hot fix, and some other, apparently unrelated things. So -- any ideas about what could cause this other Zope instance to restart silently without generating any error messages? Bear in mind that it added without incident on another machine running the same version of Python and Zope -- it has to be something specific to this other Zope setup. A general problem with my product would be expected to fail on both machines. The only time I saw something at all similar to this was a crash (on my development server) which occured because a file referenced in a DTMLFile() method didn't exist. But that at least reported an IOError in the log file, which this isn't doing. I'm aware of course, that with such a new product, this is most likely something wrong in my product -- just something that only shows up on certain configurations of Zope. What I'm looking for is some way to get more error reporting out of Zope so I can figure out what's causing the problem.

ZODB instead of relational DBMS?
by bernd kulawik 12 Jul '02

12 Jul '02

Hello Zopistas, looking through the literature about Zope I can only find information about using Zope (as a sort of web front-end) together with a relational databases as storage "behind". Does anybody use Zope's own ZODB for storing data? I know a little bit about the limitations ZODB has, but its object-oriented features and a relativ small amount of objects to store (10.000 to 20.000) make ZODB look very attractive to me. Or has anybody used another OO-DBMS or even an XML-DB like Xindice as data storage system? Thanks for hints and answers Bernd -- ________________________________________________________________________________ Access your POP email anytime, anywhere with WebMail.com (www.webmail.com) a product of Mail.com.

If you try to use the LocalFS Product in SuSE 8.0, you will see that when you try to access some "local" object, zope complains about the doc string... this is easy to correct... 332a333 + ob.__doc__ = """Empty""" And all works ok... -- Microsoft merges technologoies: Windows CE + Windows ME + Windows NT = Windows CEMENT ---- Antonio Beamud Montero Agora Systems S.A. http://www.agoratechnologies.com

DCOracle2 on NT4
by Sean Abrahams 12 Jul '02

12 Jul '02

I'm running into an Oracle error when running my python script using DCOracle2 on NT4, yet when I test it by hand in the interpreter it works fine. Using DCOracle2-1.1 on NT4/Apache, and here's the error reported: """dco2.DatabaseError: (12538, 'Error while trying to retrieve text for error ORA-12538')""" I've looked up the reason as being related to TNSNAMES.ora but why would the interpreter work and not the script? I have Perl scripts accessing it fine, so I don't think it's a User problem with Apache. Thanks, Sean

Alternate storage for ZODB
by Thierry Florac 12 Jul '02

12 Jul '02

Hi... I've seen here and there several articles about a replacement of the ZODB storage via an SQL backend, to store every Zope objects. Actually, I would like to test with a PostgreSQL storage, but I can't find any link anywhere to these kind of informations. Any link, advise or experimentation reports would be greatly appreciated...
