Hi guys I am facing a problem when trying to get the state from cache in a 2-clustered cache enviroment. What a I get from the node which is starting and trying to get the state from another node in the cluster is:
2008-03-10 11:01:20,630 WARN [org.jboss.system.ServiceController] Problem starting service jboss.cache:service=ServicesDataCache | org.jboss.cache.CacheException: Initial state transfer failed: Channel.getState() returned false As I saw in http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossCacheTroubleshooting I increased the InitialStateRetrievalTimeout parameter in the cache configuration file and everything worked fine. Then, I wanted to test setting the parameter FetchInMemoryState to false so I could test a different solution (in my case, I do not care using a cold loading cache) What I got from this test is that some cache attributes (around 55000) were transferred to the cache that is starting (there are around 90000 attributes in the other node) Perhaps, I am missing some configuration parameter. I am using Jboss Cache 1.4.1.SP8 and JbossAS 4.2.2.GA. Here is my cache config file: | <?xml version="1.0" encoding="UTF-8"?> | | <!-- ===================================================================== --> | <!-- --> | <!-- ServicesCache Service Configuration --> | <!-- --> | <!-- ===================================================================== --> | | <server> | | <classpath codebase="./lib" archives="jboss-cache.jar, jgroups.jar" /> | | | <!-- ==================================================================== --> | <!-- Defines TreeCache configuration --> | <!-- ==================================================================== --> | | | <mbean code="org.jboss.cache.TreeCache" | name="jboss.cache:service=ServicesDataCache"> | | <depends>jboss:service=Naming</depends> | <depends>jboss:service=TransactionManager</depends> | | <attribute name="TransactionManagerLookupClass"> | org.jboss.cache.JBossTransactionManagerLookup | </attribute> | | <!-- | Isolation level : SERIALIZABLE | REPEATABLE_READ (default) | READ_COMMITTED | READ_UNCOMMITTED | NONE | --> | <attribute name="IsolationLevel">NONE</attribute> | | <!-- | Valid modes are LOCAL | REPL_ASYNC | REPL_SYNC | INVALIDATION_ASYNC | INVALIDATION_SYNC | --> | <attribute name="CacheMode">REPL_SYNC</attribute> | | <!-- | Just used for async repl: use a replication queue | --> | <attribute name="UseReplQueue">false</attribute> | | <!-- | Replication interval for replication queue (in ms) | --> | <attribute name="ReplQueueInterval">0</attribute> | | <!-- | Max number of elements which trigger replication | --> | <attribute name="ReplQueueMaxElements">0</attribute> | | <!-- Name of cluster.
