Alfresco 4.0 Community Edition Clustering

[bharatbang]

We are upgrading to Alfresco 4.0 but i dont have idea which is the most stable out of 4.0a,4.0b,etc
The requirements are that we need to do clustering(HA), without content replication.

I have gone through the docs,it has a very good documentation. But i cannot decide which method to opt for clustering out of EHCache,JGroups or JLAN. :roll:

The environment i have is
RHEL 6.1,
Alfresco 4.0(to be decided,the target)
PostgreSQL
2 Physical boxes to be clustered in HA mode(without content replication).
Tomcat(default)

4.0.d is the version to go for.

But technique to go for out of JGroups,JLAN or EHCache…
Sorry but i new to Alfresco Clustering.
I am trying to get more info about Clustering, but in vain.

I think your only choice for Community is EHCache.    

AFAIK JGroups is Enterprise Only and JLAN's Hazelcast cluster is for its own use.

It says that it cannot be clustered. :roll:

That forums link says *4.2* cannot be clustered.  4.0 still has clustering support and as mrogers says, you'll need to use EHCache.  The other options are not available for CE.
