Dear All,
I am having an issue in the Ehcache Clustering using RMI Replication. I am using a Oracle 10g application server with EhCache replication. The versions are Hibernate version: 3.2.6.g and Ehcache version: 2.4.1. I am using a manual peer replication. Please find the ehcache config xml.
Code:
<?xml version="1.0" encoding="UTF-8"?>
<!-- UAT Environment Configuration -->
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd" updateCheck="false">
<!-- Location of persistent caches on disk -->
<diskStore path="java.io.tmpdir/CCD-CXIS-EhCache" />
<transactionManagerLookup
class="net.sf.ehcache.transaction.manager.DefaultTransactionManagerLookup"
properties="jndiName=java:comp/UserTransaction" propertySeparator=";"/>
<!-- Automatic Peer Discovery Cache Manager -->
<cacheManagerPeerProviderFactory
class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
properties="peerDiscovery=manual, rmiUrls=//hostname1:40002/containersCacheUAT1"/>
<!-- Peer Listener -->
<cacheManagerPeerListenerFactory
class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"
properties="hostName=hostname2, port=40002, socketTimeoutMillis=2000"/>
<!-- Default Cache Configuration -->
<defaultCache
maxElementsInMemory="10000"
eternal="false"
overflowToDisk="false"
timeToIdleSeconds="0"
timeToLiveSeconds="86400"
memoryStoreEvictionPolicy="LRU"
diskPersistent="false"
diskExpiryThreadIntervalSeconds="120"/>
<!-- Containers Cache Configuration -->
<cache
name="containersCacheUAT1"
maxElementsInMemory="100"
eternal="false"
overflowToDisk="false"
diskPersistent="false"
timeToIdleSeconds="0"
timeToLiveSeconds="86400"
memoryStoreEvictionPolicy="LRU"
transactionalMode="xa">
<cacheEventListenerFactory
class="net.sf.ehcache.distribution.RMICacheReplicatorFactory"
properties="replicatePuts=true, replicateUpdates=true, replicateRemovals=true, replicateUpdatesViaCopy=false, replicateAsynchronously=true, asynchronousReplicationIntervalMillis=500"/>
<bootstrapCacheLoaderFactory
class="net.sf.ehcache.distribution.RMIBootstrapCacheLoaderFactory" />
</cache>
</ehcache>
Now the configuration seems to be working fine for around 20 minutes. After this the cache synchronization stops working. I am not sure why this is happening. I turned on the debug to get the log statements. One of the log statements says the the Multicast Heartbeat thread is disposed. I am not sure why this should happen

One thing I can try i,s while using the rmi protocol for looking up the server, instead of hostname i can use the ip since rmi might have issues with host names. Othe than that is there anything I am missing?
Thanks,
Sriram
