That's about it for your problem. Maybe the profiling stuff can give more info, I'm not sure. > most of the z2 threads are used, although only 3-4 are used > heavily. what > does this show? It shows that four threads have database connections. I'm curious as to why you're only seeing four threads being served by database connections too. You may want to ramp your number of threads down to 5 (-t5). 25 doesn't do much for you because only 7 threads can be using database connections at any given time. The high number of threads you're servicing might actually be slowing things down as they contend for available database connections. Why are you frontending this with apache? how are you servicing two ZEO clients via a single apache? Does it do some sort of round-robining? Or does each box have its own apache? Is there any reason you're not just using straight ZServer? I'm wondering if apache processes contending to talk to available Zope python threads might be slowing stuff down? It doesn't seem as if bumping your number of database connections will do us any good here, because it doesn't seem you're using all 7. I'm not sure *why* you're not using all 7, because you've got at least 15 processes waiting around just on your top screen for DB connections. Maybe manage_debug isn't telling you the whole story, or maybe you caught it at a low-load period. I wonder if the profiling stuff would help here. Maybe someone else can jump in here, this is all I can think of at the moment.

Login and password
by Tom Deprez 11 Aug '00

11 Aug '00

Hi, I'm wondering is it possible to implement a way that Zope asks for a password, but not for a login? eg. like you would give several people the same login & password, but that the users don't have to enter the login, only the password? Thanks, Tom.

Batch Processing, final

Pfew, I managed to implement the thing I wanted. However I'm not satisfied. There must be an easier solution. If somebody knows which, then please let me know! Thanks. Here is the code I use to display something like in a search result : Previous 1 2 3 4 5 6 Next <dtml-in address_lookup size=5 start=query_start> <dtml-if sequence-start> <p>Search Result : <dtml-var count-CENTRE_NO> matches<p> <table width="100%"> <tr> <td align="left" width="60">  <dtml-if previous-sequence> <a href="<dtml-var URL><dtml-var sequence-query>query_start=<dtml-var previous-sequence-start-number>"> <dtml-var "gif_previous.tag(border='0')"></a> </dtml-if> </td> <td align="center">  <dtml-in address_lookup previous size=5 start=query_start> <dtml-in previous-batches mapping> <a href="<dtml-var document_id><dtml-var sequence-query>query_start=<dtml-var batch-start-number>"> <dtml-var "(_.getitem('batch-start-index',0)/_.getitem('batch-size',0))+1"></a> </dtml-in> </dtml-in>  <dtml-var "(_.getitem('sequence-index',0)/_.getitem('sequence-step-size',0))+1"></a>  <dtml-in address_lookup next size=5 start=query_start> <dtml-in next-batches mapping> <a href="<dtml-var document_id><dtml-var sequence-query>query_start=<dtml-var batch-start-number>"> <dtml-var "(_.getitem('batch-start-index',0)/_.getitem('batch-size',0))+1"></a> </dtml-in> </dtml-in> </td> <td align="right" width="60">  <dtml-if "((_.getitem('sequence-index',0)+_.getitem('sequence-step-size',0))+1) < (_.getitem('count-CENTRE_NO',0))"> <a href="<dtml-var URL><dtml-var sequence-query>query_start=<dtml-var "(_.getitem('sequence-index',0)+_.getitem('sequence-step-size',0))+1">"> <dtml-var "gif_next.tag(border='0')"></a> </dtml-if> </td> </tr> </table> </dtml-if sequence-start> .... show present page results ... </dtml-in> Regards, Tom.

Batch processing
by Tom Deprez 11 Aug '00

11 Aug '00

Hi, few q'ns concerning batch processing: 1. I want the user to be able to choose a batch-page. So, when a query is done, I want to show something like : previous page 1 - 2 - 3 - 4 - 5 next page. The following code works partly: ie. the one thing missing is that it doesn't shows the current page. How can I implement this? <dtml-in address_lookup previous size=5 start=query_start> <dtml-in previous-batches mapping> <dtml-unless sequence-start>  </dtml-unless> <a href="<dtml-var document_id><dtml-var sequence-query>query_start=<dtml-var batch-start-number>"> <dtml-var "(_.getitem('batch-start-index',0)/_.getitem('batch-size',0))+1"></a> </dtml-in> </dtml-in> <dtml-in address_lookup next size=5 start=query_start> <dtml-in next-batches mapping> <dtml-unless sequence-start>  </dtml-unless> <a href="<dtml-var document_id><dtml-var sequence-query>query_start=<dtml-var batch-start-number>"> <dtml-var "(_.getitem('batch-start-index',0)/_.getitem('batch-size',0))+1"></a> </dtml-in> </dtml-in> <dtml-in address_lookup size=5 start=query_start> ... </dtml-in> 2. Is there an easier way to get what I want? 3. Does the above code means that it has to iterate 3 times over the list? Isn't there a way so that it needs only one pass over the list? Thanks in advance, Tom Deprez.

access via http://<some domain>/Zope/
by Michael Demers 11 Aug '00

11 Aug '00

I have Zope running on two seperate machines. I configured the machines EXACTLY the same. The development machine which is MASQed behind the production machine can access Zope via http;//localhost:8080 and http://localhost/Zope/ The production machine can be accessed via http://www.nitemaster.yi.org:8080 but not by http://www.nitemaster.yi.org/Zope/ When I try to access via the second method, I keep getting a FORBIDDEN error message. I have searched file permissions comparing the two implementations to no avail. System specs to follow in case it is something with those but I don't believe so. Development Machine RedHat 6.2 Apache 1.3.12 (Standard Install from RedHat) Zope 2.2.0 Production Machine RedHat 6.1 Apache 1.3.12 - (Custom Install from Sources) - /usr/local/apache/ source tree Zope 2.2.0 I am sure it has something to do with permissions somewhere but I am at a loss. ls -l /usr/local/apache/cgi-bin/Zope.cgi -rwxr-xr-x 1 nobody nobody 582 Aug 10 22:16 Zope.cgi ls -l /usr/local/Zope-2.2.0-linux2-x86/pcgi/pcgi-wrapper -rwxr-xr-x 1 nobody nobody 36231 Aug 10 22:25 /usr/local/Zope-2.2.0-linux2-x86/pcgi/pcgi-wrapper If there are any other files that you want the permissions for, just let me know :) Michael Demers Nitemaster Consulting Services mdemers(a)nitemaster.yi.org

Reloading file objects?
by Peter Arvidsson 11 Aug '00

11 Aug '00

I have file-objects containing pdf-files. When I change the object to contain another pdf-file (with "manage_upload") I get a problem. When I want to view the file it still shows the old file. However when I choose save to disk I get the new object and if I take a look at its properties (size etc...) they are for the new object. Does anyone know a way to get the file to show the new pdf-file when I want to view it? I have tried to put <META HTTP-EQUIV="Pragma" CONTENT="no-cache"> in the page where I have the link to the file but that doesnt affect the file when I open it. The link I use are the path for the file as it is on the view-tab of the object. Is there some way to get it to show the new file when I view it and not only when I save it to disk or open it in a new window?
