Re: [Zope] Zeo question
Ola, thx maciej and Jonathan...your answers have helped a lot Each zope instance can access multiple ZODB's (as Maciej mentions later), which means that the zope instance can access both a shared zodb and a local zodb which is specific to the zope instance. auaua...i didn't know that ;)...this is really cool. Now the inevitable question - 'Is there any documentation about how to set this up ?' Maybe I just define another zodb_db in my zope.conf and mount it into a folder like maciej said and just customize this folder. What i need to do is just create a custom skin on each zope instance to show that it is Manaus,Belem or wherever serving the information but have the same global content shown in each instance. From what you have said it seems this should be possible with a bit of tweaking Zope is very flexible! You just need to build a configuration which meets your use case! welcome to OSS, eh !

Maybe I just define another zodb_db in my zope.conf and mount it into a folder like maciej said and just customize this folder. To set up multiple mount points you need to edit your zope.conf (to configure the various mount points), then you need to Add 'ZODB Mount Point' via the ZMI at the appropriate location (note: this is for zope 2.7+). You can google for 'zodb mount points' if you need more info. What i need to do is just create a custom skin on each zope instance to show that it is Manaus,Belem or wherever serving the information but have the same global content shown in each instance. From what you have said it seems this should be possible with a bit of tweaking You can easily do this by changing the 'display' routines on each zope instance. Another method I have used is to set up URL subdomains for each 'different' entry point and then use Apache rewriting to automagically redirect the user to the correct location within the zope instance (ie. a different folder for each subdomain) - this allows you to have each zope instance be a real 'copy' (and not have to maintain different versions), but it depends on your use case as to which method is most appropriate for you!

Ola, You can easily do this by changing the 'display' routines on each zope instance I feel so stupid asking but what do you mean by this...i have googled but cannot find anything about 'zope display routines' ... Do you mean this: In the zope instances I can create a folder custom and place my customizations in there.. -- so I create logo_manaus.jpg for Manaus and this goes in the folder custom on the zope instance in Manaus and then i create logo_belem.jpg for Belem in the folder custom on the zope instance in Belem...and we live happily ever after ;) -- I think my problem is that i do not really understand what is stored in the ZODB...is it just content or is it content and configuration []'s -- Ian Lawrence http://ianlawrence.info Centre for Bioinformatics INSTITUTO NACIONAL DE PESQUISAS DA AMAZÔNIA-INPA RUA ANDRÉ ARAÚJO N º .2936 , BAIRRO DO ALEIXO MANAUS-AMAZONAS-BRAZIL Research Program in Biodiversity http://ppbio.inpa.gov.br PHONE: 055-92-3643-3358 CEP. 69011 -970 | Please do not send me documents in a closed | format.(*.doc,*.xls,*.ppt) | Use the open alternatives.

Re: [Zope] Zeo question
2. I can create a custom skin on each zope (in reality plone) instance right or is each zope instance is just a mirror of the other? Nope. It is something different. In general ZEO is about sharing ZODB (Zope Object Database) between few Zope instances. There is no mirroring but just one ZODB. ZODB is a place where all objects you have created through ZMI (Zope Management Interface) are hold. When you have standard setup (one Zope instance) it has it's own ZODB (you may see this in instance/var/data.fs. With ZEO you have ZEOServer that holds ZODB (data.fs file) and multiple ZEO Clients that are connecting to it. ZEOClient is a normal ZopeInstance that is not using it's own data.fs (ZODB) but shared one. Because of this, every object created/changed/removed on one ZEOClient is removed from shared ZODB therefore all ZEOClient see this. There is more things that can be done. You may for example define (in zope.conf) mount points for folders that are individual for each zope etc. -- Maciej Wisniowski ___ Zope maillist - Zope@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 )
