Hi, I would like to know more about the offline mode.
In the documentation page (http://www.eclipse.org/cdo/documentation/) I just found the definition of the two possibilities available:
- the complete clone
- the checkout of a single model with no history
there are examples available?
do you suggest to use this functionality for production code?

This is considered production quality, and already used in production.

Here's an example:
http://git.eclipse.org/c/cdo/cdo.git/tree/plugins/org.eclipse.emf.cdo.examples/src/org/eclipse/emf/cdo/examples/server/offline
(also available via p2)

> - the checkout of a single model with no history
This is comparingly new functionality. For usage examples please look for callers of
org.eclipse.emf.cdo.workspace.CDOWorkspaceUtil.createWorkspaceConfiguration().

Cheers

The example is clear and interesting. I am playing with it. At the moment I am this strange behaviour:
if I launch the cloned server before the master server it keeps running without errors (I just start it without executing operations on it). As soon as I start the master server the cloned server start opening sessions (one per second more or less). Is it the expected behaviour?

No, that sounds odd. Please submit a bugzilla so that I can analyze it.

Now this behaviour seems to happen when I first start the master and I commit something there. The clone when started try to sync again and again. If I start a clean master, then the clone and I operate only on the clone changes are reported to the master and everything seems to be working. Maybe I am supposed to work always on the clone and never operate directly on the master? Is just the clone that pushes its changes to the master but not the viceversa?
