Hi all, I got a problem when use JBoss Cache 1.4.0 within JBoss AS 4.0.2. I have two application servers. when they start up, the caches can find each other, and fetch the in-memory status successfully. But when I put an object into cache A, it does not replicate the object to cache B; however, when I remove this object from A, it's also removed from B.... Yes, the insert is not replicated while the removing is replicated successfully. what's wrong with my configuration? Please help me. <!-- ==================================================================== --> | <!-- JBoss Cache --> | <!-- ==================================================================== --> | <mbean code="org.jboss.cache.TreeCache" name="jboss.cache:service=V360WebLayerCache"> | <depends>jboss:service=Naming</depends> | <depends>jboss:service=TransactionManager</depends> | <attribute name="TransactionManagerLookupClass"> | org.jboss.cache.JBossTransactionManagerLookup | </attribute> | <attribute name="IsolationLevel">REPEATABLE_READ</attribute> | <attribute name="CacheMode">REPL_SYNC</attribute> | <attribute name="FetchInMemoryState">true</attribute> | <attribute name="ClusterName">${aa.cache.cluster.name}.web</attribute> | <attribute name="ClusterConfig"> | <config> | <UDP mcast_port="${aa.cache.cluster.port}" ip_ttl="64" ip_mcast="true" | mcast_send_buf_size="150000" mcast_recv_buf_size="80000" | ucast_send_buf_size="150000" ucast_recv_buf_size="80000" | loopback="false" /> | <PING timeout="2000" num_initial_members="3" | up_thread="false" down_thread="false" /> | <MERGE2 min_interval="10000" max_interval="20000" /> | <FD shun="true" up_thread="true" down_thread="true" /> | <VERIFY_SUSPECT timeout="1500" up_thread="false" | down_thread="false" /> | <pbcast.NAKACK gc_lag="50" | retransmit_timeout="600,1200,2400,4800" up_thread="false" | down_thread="false" /> | <pbcast.STABLE desired_avg_gossip="20000" | up_thread="false" down_thread="false" /> | <UNICAST timeout="600,1200,2400" window_size="100" | min_threshold="10" down_thread="false" /> | <FRAG frag_size="8192" down_thread="false" | up_thread="false" /> | <pbcast.GMS join_timeout="5000" | join_retry_timeout="2000" shun="true" print_local_addr="true" /> | <pbcast.STATE_TRANSFER up_thread="false" | down_thread="false" /> | </config> | </attribute> | <attribute name="InitialStateRetrievalTimeout">20000</attribute> | <attribute name="SyncReplTimeout">15000</attribute> | <attribute name="LockAcquisitionTimeout">10000</attribute> | <!--attribute name="EvictionPolicyClass">org.jboss.cache.eviction.LRUPolicy</attribute> | <attribute name="EvictionPolicyConfig"> | <config> | <attribute name="wakeUpIntervalSeconds">200</attribute> | <region name="/${aa.cache.web.fid.root}"> | <attribute name="maxNodes">${aa.cache.web.fid.maxNode}</attribute> | <attribute name="timeToLiveSeconds">${aa.cache.web.fid.timeToLive}</attribute> | </region> | <region name="/${aa.cache.web.guitext.root}"> | <attribute name="maxNodes">${aa.cache.web.guitext.maxNode}</attribute> | <attribute name="timeToLiveSeconds">${aa.cache.web.guitext.timeToLive}</attribute> | | </region> | <region name="/${aa.cache.web.bizdomain.root}"> | <attribute name="maxNodes">${aa.cache.web.bizdomain.maxNode}</attribute> | <attribute name="timeToLiveSeconds">${aa.cache.web.bizdomain.timeToLive}</attribute> | | </region> | <region name="/${aa.cache.web.constant.root}"> | <attribute name="maxNodes">${aa.cache.web.constant.maxNode}</attribute> | <attribute name="timeToLiveSeconds">${aa.cache.web.constant.timeToLive}</attribute> | | </region> | <region name="/${aa.cache.web.gview.root}"> | <attribute name="maxNodes">${aa.cache.web.gview.maxNode}</attribute> | <attribute name="timeToLiveSeconds">${aa.cache.web.gview.timeToLive}</attribute> | | </region> | <region name="/${aa.cache.web.general.root}"> | <attribute name="maxNodes">${aa.cache.web.general.maxNode}</attribute> | <attribute name="timeToLiveSeconds">${aa.cache.web.general.timeToLive}</attribute> | | </region> | </config> | </attribute--> | </mbean> | | | | <!-- ==================================================================== --> | <!-- JBoss Cache JNDI --> | <!-- ==================================================================== --> | <mbean code="org.jboss.invocation.jrmp.server.JRMPProxyFactory" | name="mydomain:service=proxyFactory,type=jrmp,target=factory"> | <attribute name="InvokerName"> | jboss:service=invoker,type=jrmp | </attribute> | <attribute name="TargetName"> | jboss.cache:service=V360WebLayerCache | </attribute> | <attribute name="JndiName">${aa.cache.jndi.name}</attribute> | <attribute name="InvokeTargetMethod">true</attribute> | <attribute name="ExportedInterface"> | org.jboss.cache.TreeCacheMBean | </attribute> | <depends>jboss:service=invoker,type=jrmp</depends> | <depends>jboss.cache:service=V360WebLayerCache</depends> | </mbean> | All the ${} variables are in an individual file.
