RE: [Zope] Cheap LINUX Zope host?

Using IDE on a dual-proc Linux server is a "bad idea". Use SCSI for any machine you propose to host multiple users on. If you must use IDE, throw some DIMMS in the poor box and rely on cache to speed things up. Also, if you're running a UDMA-66 system, and have a controller (and drive, etc) that can handle it, you can speed things up quite a bit with hdparm: hdparm -u1 -c1 -k1 -m16 -d1 -X66 /dev/hda PLEASE DO NOT TRY THE ABOVE COMMAND BEFORE YOU RTFM. If you loose data, there is nothing I can do to help you. TEST THIS CAREFULLY. TEST THIS FULLY. Don't do this to a production server, PLEASE. This works GREAT on a FIC SD-11 Athlon system (VIA "VP3" 82C59x based Southbridge) after enabling the driver support in the kernel along with a WD 27g UDMA66/7200rpm drive. On an overclocked dual-celery system running two IDE IBM 16Gb drives at home, attempting to tweak my IDE settings with the onboard Intel chipset causes the machine to reliably lock solid EVERY TIME. I have been running Zope on the above dual-celery system for quite some time. Aside from the 2gb file limit, everything has run very smoothly. The biggest noticable changes are when DMA is enabled, and when IRQ unmasking is turned on. YMMV. - Ian C.

Oops, I'm going to use LINUX as the host OS. I've done a bit of research on using SCSI. IWill & Tekram put out SCSI3 cards under $70 (according to http://www.pricewatch.com) Anyone use these guys? However, I'm not sure a cheap/close-out SCSI drive will match the performance-to-value ratio to a new ATA-66. http://www.storagereview.com has lots of drive tests that leads me to this thought. If I was spending more than $1000 for a new system, I'd go SCSI for sure. I need to keep below $700, but SCSI is one of my first planned upgrades. Is SCSI worth me getting a old used system with 64MB of RAM & slapping a SCSI card into it, or should I go for a new (dual) Celeron with 128MB? Has anyone actually done performce tests with Zope & SQL to compare what component has the most impact for a _cheap_ system: CPU, memory, or HD throughput (ATA vs SCSI)?

However this may take you into the next price point segment ~1000$. I have found there are good bargains on SCSI drives to be had on eBay and ONSALE auctions - go for new and 7200RPM or more. --== Sent via Deja.com http://www.deja.com/ ==-- Share what you know.

ZClasse default in the product
by Jean Rodrigo Ferri 15 Nov '99

15 Nov '99

Greetings again, I created a Product with 16 ZClasses, however these 16 classrooms are listed in the box of selection "Available Objects" : -), where it would need that only the main classroom was listed. I only qualify the main classroom through permissions or exists some "trick", as I make? []'s -- Jean Rodrigo Ferri mailto:ferri@detec.unijui.tche.br

Visualization of inherited attributes
by Jean Rodrigo Ferri 15 Nov '99

15 Nov '99

Greetings, I created an abstract ZClasse call "person" and a "service_prestator" ZClasse that it inherits the classroom "person". It would like to only visualize in a border (view) the attributes of the two classrooms, for this, I created a method calling the attributes these classrooms and it I associated one " view ". The problem is that I do not obtain to codify this call of the attributes (propertysheets/atribute1/manage and propertysheets/atribute2/manage). Some suggestion?

Trying to Install ZMySQLDA
by Robert Canary 15 Nov '99

15 Nov '99

Hi agin, I am agin trying to install the ZMySQLDA. I upragded my Zope to the 2.0.1 from the rpm on the RedHat 6.1 distro and I am runing python-1.5.2. Now according to the instructions from the ZmySQLDA I am suppose to un tar this from the top directory of the Zope. If I go to /usr/lib/python1.5/site-packages/ and unpack everything it ends up with a /usr/lib/python1.5/site-packages/lib/python/Products/ZMySQLDA/{all the tared files} + {a src directory to build the mysqlmodule}. However, this is obviously not right. The only "Products" I found was under the "ZopeWorld" directory. However, manually place the contents of the tarball's "Product" directory in this directory did not help iether. No matter which way I go I get this error when I do make in the ZMySQLDA/src directory. This is the output. [root@mchn3 src]# make sharedmods gcc -fPIC -I/usr/include/mysql -g -O2 -I/usr/include/python1.5 -I/usr/include/python1.5 -DHAVE_CONFIG_H -c ./MySQLmodule.c ./MySQLmodule.c: In function `pythonify_row': ./MySQLmodule.c:238: warning: assignment from incompatible pointer type ./MySQLmodule.c: In function `pythonify_res_fields': ./MySQLmodule.c:384: invalid lvalue in unary `&' ./MySQLmodule.c: In function `STH_fetchdict': ./MySQLmodule.c:1125: invalid lvalue in unary `&' ./MySQLmodule.c:1147: invalid lvalue in unary `&' make: *** [MySQLmodule.o] Error 1 I really need some help with this one, any volunteers? thanks in advance ;-) -- robert canary

need zcatalog help !
by Geir B Hansen 15 Nov '99

15 Nov '99

Help ! i have a problem with zcatalog-reports : i use a GET-form to define which items form the zcatalog to display in my intranet-phonelist. Problem is, the form appends all variables in the form,even the ones without any value. used on fieldindexes, this seems to be a grave problem, as Zcatalog obviously intreprets a variable without any value as 'show all instances that have a value of nothing for this variabe' instead of 'show all intances' the url : http://my.machinecom/phonelist/index_html?meta_type=employee gives me what i want, while : http://my.machinecom/phonelist/index_html?meta_type=employee&team= returns nothing. is there anyway i can make Zcatalog know i want all instances if team="" ?? i was thinking of adding something in the line of this in the start of the phonelist (report) -document : <dtml-unless team> <dtml-call "REQUEST.set('team',' something like "Catalog.uniqueValuesFor('team')" although this wont work ')"> </dtml-unless> any ideas what i'm doing wrong ? ------------------------------------------------ Geir B Hansen geirh(a)funcom.com Web-designer / Graphic artist Funcom Oslo http://www.funcom.com ------------------------------------------------

version deleted but there is still a version lock
by Andy Pahne 15 Nov '99

15 Nov '99

I have a Zope folder which contained a version a long time ago. The version was deleted, but in the management-screens I always get a version lock. I cannot add documents, and I cant change a few of the existing docs. How can I make my existing objects notify that theres no version anymore and therefore no locking necessary? Unluckily this happened with a projectsite we have on the net. There are a lot of people waiting to see new content which I cannot add.... yours, andy ap(a)net22.net

It exists... and yet it doesn't!
by taliesin＠nvg.org 15 Nov '99

15 Nov '99

I have a bizarre error/bug/feature here... I have a folder whose contents behave very strangely. Any file named index_html reverted back to the standard for newly made DTML Documents after a few minutes, but luckily I was able to delete it. However, while I wasn't watching the external methods that also were (and still are) in that folder mutated into folders themselves - and now they are impossible to delete, I get a keyerror. If I try to enter them, or do anything else I get 'resource not found'. I can't delete the parent-folder either. So: how do I get rid of them? t.
