Hi Niels,
what you want is the CacheLoader interface, that I'm currently working on. Wait until
J1 for an announcement. .. :-)
But here's in a nutshell what it does:
- get() fetches the data from cache. If not found, ask the cache loader to load it.
- put() puts the data into the cache. if repli
Currently we are using a home grown caching solution to avoid multiple lookups of the
same object from the database. However our own caching logic is not transaction
aware, so we are looking to replace it with a third party caching solution that is,
potentially TreeCache.

What you essentially want is a state-merge function after e.g. a network partition.
This is actually on the roadmap, but it involves asking you (the application) how to
merge 2 (potentially) different substates back into one. We *cannot* just take the
union of the 2 substates, because an applica

earlier.

hi Ben,
thanks for replying.
here's a graph of LRU-enabled test benchmark. The only thing it does is makes put()s
in JBossCache. Test is a standalone app, no interference with anything, no Hibernate
or whatever. This snapshot is with wakeUpTime=5sec

Hi,
thanks for your answer. It would be nice to have such an option. Because otherwise
we're getting problems with data inconsistency.
To do a workaround with stopping and starting the cache in such cases automatically,
we first should know when a machine has no connection to the cluster anymore
Since the cache has started on Machine B already, it won't initiate another state
transfer from other members when re-joining the group since it can be expensive
operation. If you stop and start the cache on Machine B (say, from JMX console via
MBean service), then it should sync up.
But I will
It is hard to say whether it is a bug in deployer. But it definitely is weird. I will
look into it soon.
Thanks,
-Ben

Rich,
Can you send me a sample log file with "org.jboss.cache" category and "DEBUG" level
tracing from log4j.xml? In there is a detailed log for lock information.
Thanks,

Regarding to performance, SYNC mode has to be slower than ASYNC since it is blocking.
But if you have read-mostly data, then it can be acceptable. Otherwise, use ASYNC if
you can.
For LRU, basically there is a TimerTask thread that wake up every x seconds to check
for the node event queue. Do y
We're testing with TreeCache regarding cluster-abilities.
The cache is not synchronized to a node that had no network connection and reconnects
to the cluster.
- We have a cluster of 2 linux machines, jboss 3.2.4 (final) with Treecache that was
delivered with jboss 3.2.4.
- Cache is configured
Under jboss-head/testsuite/src/main/org/jboss/test/cache/bean, there is
TreeCacheAopMBenaTesterBean.java that is using TreeCacheAop as a MBean service. Check
it out.
Thanks,

What version of JBoss are you trying to shutdown? Please provide as much environment
information as possible. Thanks.

most likely there are problems w/ this module - it hasn't been "officially" released
and no one is actively maintaining it.
if one of you would like to look into it and submit patches, that would be great.

Hi There,
I hope this is the right place to post this, I think I've found a bug with the naming
component of JBoss 3.2.4. I've tested with JDK 1.4.2_02 and 1.4.2_04. This problem was
not in the previous version we were using (3.2.3) and was discovered initially upon
upgrade. The problem seems

Hello altogether!
I'm on my way to establish a TreeCache (-AOP) instance for a clustered JBoss
environment. Last weeks I came closely in touch with (standalone) TreeCache technology.
Now, I'm trying to get this thing into JBoss.
1.) I deployed a XML file cache-service.xml with following content
I have the same problem, also! ! Nobody decides it?
Thanks in advanced.
