Wildfly 10.1.0 Final and infinispan Cache problem sync

rbelfils Aug 2, 2017 3:25 AM

Hello,

i have some problems with cache and cluster mode (UDP) Wildfly 10.1.0Final :

standalone-ha.xml:

<cache-container name="replicated_cache" default-cache="default" module="org.wildfly.clustering.server"  jndi-name="infinispan/replicated_cache">
     <transport lock-timeout="60000"/>
     <replicated-cache name="default" mode="SYNC" jndi-name="infinispan/replicated_cache/hemisCache">
          <transaction locking="OPTIMISTIC" mode="FULL_XA"/>
          <eviction strategy="NONE"/>
     </replicated-cache>
     <replicated-cache name="listKernels" mode="SYNC" jndi-name="infinispan/replicated_cache/listKernels">
          <transaction locking="OPTIMISTIC" mode="FULL_XA"/>
          <eviction strategy="NONE"/>
     </replicated-cache>
     <replicated-cache name="containersAvailableKernels" mode="SYNC" jndi-name="infinispan/replicated_cache/containersAvailableKernels">
          <transaction locking="OPTIMISTIC" mode="FULL_XA"/>
          <eviction strategy="NONE"/>
     </replicated-cache>
     <replicated-cache name="containersKernels" mode="SYNC" jndi-name="infinispan/replicated_cache/containersKernels">
          <transaction locking="OPTIMISTIC" mode="FULL_XA"/>
          <eviction strategy="NONE"/>
     </replicated-cache>
     <replicated-cache name="containersByProfile" mode="SYNC" jndi-name="infinispan/replicated_cache/containersByProfile">
          <transaction locking="OPTIMISTIC" mode="FULL_XA"/>
          <eviction strategy="NONE"/>
     </replicated-cache>
     <replicated-cache name="containers" mode="SYNC" jndi-name="infinispan/replicated_cache/containers">
          <transaction locking="OPTIMISTIC" mode="FULL_XA"/>
          <eviction strategy="NONE"/>
     </replicated-cache>

</cache-container>

i declare in my singleton :

Head Class singleton :

@Singleton
@ConcurrencyManagement(ConcurrencyManagementType.CONTAINER)
@Lock(LockType.READ)
@AccessTimeout(Constant.ACCESS_TOKEN_TIMEAOUT)
@Startup
public class KernelsManagerSingleton extends AbstractObjectManagement<Kernel>
{
....
@Resource(lookup = "java:jboss/infinispan/replicated_cache/containersAvailableKernels")
Cache<String, TreeSet<Kernel>> containersAvailableKernels;


...


//Method put some items in cache :
if (!containersByProfile.containsKey(container.getContainerProfile().getId()))
{
     containersByProfile.put(container.getContainerProfile().getId(), new HashSet<String>());
}

Résult :

My cache never sync correctly !

have a an idea ?

is infinispan can Cache a complex structure as TreeSet<Kernel> ?

Kernel is an Entity Hibernate(JPA).

thx a lot for your help.

Romain.

Based on the IRC discussion, you're expecting any update to the TreeSet value to be automatically visible in the cache.

Infinispan does not do that, cache.get(key) will always return the initial value on other nodes. In fact it will return the initial set even on the same node, if the cache is configured with

<memory>
<binary/>
</memory>
