salut Thierry,

have you looked at ZSyncer? http://www.zope.org/Members/andym/ZSyncer

hope this helps

Hi, I took a look at ZSyncer, and I think that this might be the good solution for me, at least to be able to synchronize simple objects like DTML Methods or Python scripts. But two more questions : - what are the requirements to be able to synchronize custom Zope products instances ? - are the permissions also synchronized ?? Many thanks, Thierry

Thierry,

You can set up ZSyncer to synchronise products installed on both systems, so although you'll still have to install those on both systems, when you have done so, you will be able to set up the ZSyncers to synchronise the instances of those products no problem. I use this for some non-standard install products, like Xron DTML methods, so It should do your custom products too.

It syncs my custom products just fine. Be aware that zsyncer basically: - "exports" the stuff you're syncing to an in-memory pickle - transmits the pickle across the network - uses xml-rpc to have the remote server import this pickle So it's pretty much just a more convenient way to do import/export. I mention this because import / export of large items can take a looooong time. I don't recommend using zsyncer to transer 200 MB of stuff at once, or you'll be waiting forever for a success message. I've done this and gotten success eventually, but I feel a lot safer syncing in smaller batches. There are also some thorny issues, like unless the system time on the two systems is in sync, zsyncer will give you misleading information about what is and isn't in sync. -- Paul Winkler http://www.slinkp.com Look!

ah yes, that explains some strangeness I've seen. what are the other thorny issues you've come across?

That's about it, but it's very annoying and i'm not sure it's even behaving correctly within those constraints. the only other one is the limitation on pushing huge amounts of stuff at once. -- Paul Winkler http://www.slinkp.com Look!
