It seems that if I evict FQN.ROOT, only evicts nodes at primary level, and not 
its descendants.

I was already working on it, although I didn't thought on passivation, rather 
in a cache.put for every node. I'll try cache.evict, as it seems rather easier.

an idea would be to have a small program that 
a) starts a new cluster instance which would fetch all in memory state
b) this instance uses passivation
c) call cache.evict after state retrieval finished
d) exit

Is there an easy way to save all in-memory state to Database. I need to update 
database state, since it may be corrupt, prior to updating my running instances 
with a patched version of JDBCCacheLoader with the fix you suggested?

Any help will be appreciated.

Hang on, I'm confused - so you don't use Hibernate and you don't make direct 
JDBC calls, am I correct?  You just want to use the JDBCCacheLoader?

[manoj.java]

sorry to putting wrong word in last post. jboss caching is not used with 
Hibernate. simple JDBC is used for jboss caching.

Please let me know why i am getting this error.

Regard,
-Manoj

Why would you use a JDBC cache loader when using JBC as a 2nd level cache in 
Hibernate?  Storing stuff in a DB twice over is pretty wasteful, IMO.

thanks for spotting this.
This is a bug, indeed.
I've created http://jira.jboss.com/jira/browse/JBCACHE-1384
It is good that override is false at that point (that means that we do not want 
to *replace* the existing value). The problem is that overriding logic is 
broken, the old values override the new ones.
Here is my fix:
anonymous wrote : if(!override && oldNode != NULL_NODE_IN_ROW && 
attrs != null)
  | {
  |Map newOne = new HashMap(oldNode);
  |if(attrs != null) newOne.putAll(attrs);
  |attrs = newOne;
  | }
