Hi Tim,

I missed that one.. To make xwiki cluster aware the following things 
need to be worked on / checked

- Structures that are used for cache and which could contain data that 
can be changed should be moved to an XWikiCache object.. I think only 
the stats module currently has some data like that (it's possible to 
deactivate stats also). XWikiCacheStore and XWikiGroupServiceImpl 
currently use such XWikiCache structures.
- Then XWikiCache, which users OSCache, needs to be configured for 
broadcasting changes on the cluster. This means looking at how OSCache 
should be configured for this. I think the JGroups broadcast would be fine..

Otherwise from that, good testing should be done and check if anything 
else comes up..
We can definitively provide some support if you put some developer 
resources on this..

 Ok,
 Ask on the developper list. Ludovic will help you. I have no
 experience with clusters.
 The main problem for the cluster is the document cache I think.

   Hello, 

  I saw your response.  I would like to know what needs to be changed.  I do
 not have much developer experience, but where I work, there is a staff of
 developers on hand.

  Thanks,
