Infinispan cluster as hibernate second level cache

[alexlooi]

Hi,

I am trying to setup Hibernate's second level cache to use Infinispan. I have succeeded in doing this on a single instance (node?) of the application.

I believe this is working because when I execute the same query against hibernate, the first time it executes the select but any subsequent queries look like it is going to the cache (the select query doesn't get executed or is not shown in the log).

I want to now cluster the cache so that when another instance of the application starts it joins the cluster and replicates the entities in memory across. I tried to start another instance of the application up but it doesn't seem to join the cluster even though the cluster name is the same. If this is possible can someone please show me the configuration or point me in the right direction.

Thanks in advance.

Have you tried testing that the nodes can see each other in the first place? The JGroups Draw test is a good starting point, see the JGroups docs on how to do this.

I've tested Infinispan on it's own (without Hibernate/JPA) and it was working. Only when used with Hibernate/JPA I am having problems.

Apart from @Cache and the usual entity annotations, do we have to annotate the entity with anything else?

I have also followed the instructions documented here
http://www.jboss.org/community/wiki/UsingInfinispanasJPAHibernateSecondLevelCacheProvider

I am running out of ideas.

Thanks.

alexlooi, What information are you using exactly to determine that the cluster does not seem to join? Remember that as explained in the wiki, by default, entities are not replicated but instead are invalidated. So, changes you make to an entity are not replicated to other nodes but instead stale entities are invalidated in other cluster nodes.
