I'm trying a POC for synching local caches in a cluster. I'm using JCS Remote Cache server for the same. I have set up the server in Tomcat on my local box and am running two clients on my local machine as well. I would like to enable data invalidation instead of data replication across the clients, hence have set the property RemoveUponRemotePut to true. What I understand from this property is that if a cache element is present on both clients and client1 updates its local copy, then a remove request will be issued for client2 so that the next request for that element will force client2 to go to the DB to retrieve a fresh copy of the element, hence maintaining cache coherence across the cluster.
What I have instead found, is that irrespective of whether RemoveUponRemotePut is set to true or false, the behavior is as follows: 1. Add element to Client1 . 2. Add element to Client2. 3. Update element in Client1. Result - The element in Client2 also gets updated with the new value. - This is not desired, I'd like the element to be removed from Client2's cache at this point, instead of the element being replicated in client2's cache. My configuration files (both server and client) are listed below. Could you please point out what I'm making a mistake with. I tried setting the value to true and to false and I still get the same behavior for both settings. Thanks, Avanti My client CCF file looks as follows: # DEFAULT CACHE REGION jcs.default=RFailover jcs.default.cacheattributes=org.apache.jcs.engine.CompositeCacheAttribut es jcs.default.cacheattributes.MaxObjects=100000 jcs.default.cacheattributes.MemoryCacheName=org.apache.jcs.engine.memory .lru.LRUMemoryCache jcs.default.cacheattributes.UseMemoryShrinker=false jcs.default.cacheattributes.MaxMemoryIdleTimeSeconds=3600 jcs.default.cacheattributes.ShrinkerIntervalSeconds=60 jcs.default.elementattributes=org.apache.jcs.engine.ElementAttributes jcs.default.elementattributes.IsEternal=false jcs.default.elementattributes.MaxLifeSeconds=21600 jcs.default.elementattributes.IdleTime=1800 jcs.default.elementattributes.IsSpool=false jcs.default.elementattributes.IsRemote=false jcs.default.elementattributes.IsLateral=false # PRE-DEFINED CACHE REGIONS jcs.region.testCache1=RFailover jcs.region.testCache1.cacheattributes=org.apache.jcs.engine.CompositeCac heAttributes jcs.region.testCache1.cacheattributes.MaxObjects=100000 jcs.region.testCache1.cacheattributes.MemoryCacheName=org.apache.jcs.eng ine.memory.lru.LRUMemoryCache jcs.region.testCache1.cacheattributes.UseMemoryShrinker=false jcs.region.testCache1.cacheattributes.MaxMemoryIdleTimeSeconds=3600 jcs.region.testCache1.cacheattributes.ShrinkerIntervalSeconds=60 jcs.region.testCache1.cacheattributes.MaxSpoolPerRun=500 jcs.region.testCache1.elementattributes=org.apache.jcs.engine.ElementAtt ributes jcs.region.testCache1.elementattributes.IsEternal=false # Remote RMI Cache set up to failover jcs.auxiliary.RFailover=org.apache.jcs.auxiliary.remote.RemoteCacheFacto ry jcs.auxiliary.RFailover.attributes=org.apache.jcs.auxiliary.remote.Remot eCacheAttributes jcs.auxiliary.RFailover.attributes.FailoverServers=localhost:1111 jcs.auxiliary.RFailover.attributes.RemoveUponRemotePut=true jcs.auxiliary.RFailover.attributes.GetOnly=false The server's cache.ccf file looks as follows: registry.host=localhost registry.port=1111 remote.cache.service.port=1111 remote.cache.rmiSocketFactoryTimeoutMillis=5000 remote.cluster.LocalClusterConsistency=false remote.cluster.AllowClusterGet=false # # DEFAULT CACHE REGION jcs.default= jcs.default.cacheattributes=org.apache.jcs.engine.CompositeCacheAttribut es jcs.default.cacheattributes.MaxObjects=1000 jcs.default.cacheattributes.MemoryCacheName=org.apache.jcs.engine.memory .lru.LRUMemoryCache jcs.default.cacheattributes.UseMemoryShrinker=false jcs.default.cacheattributes.MaxMemoryIdleTimeSeconds=3600 jcs.default.cacheattributes.ShrinkerIntervalSeconds=60 jcs.default.elementattributes=org.apache.jcs.engine.ElementAttributes jcs.default.elementattributes.IsEternal=false jcs.default.elementattributes.MaxLifeSeconds=21600 jcs.default.elementattributes.IdleTime=1800 jcs.default.elementattributes.IsSpool=false jcs.default.elementattributes.IsRemote=false jcs.default.elementattributes.IsLateral=false # # PRE-DEFINED CACHE REGIONS jcs.region.testCache1= jcs.region.testCache1.cacheattributes=org.apache.jcs.engine.CompositeCac heAttributes jcs.region.testCache1.cacheattributes.MaxObjects=1000 jcs.region.testCache1.cacheattributes.MemoryCacheName=org.apache.jcs.eng ine.memory.lru.LRUMemoryCache jcs.region.testCache1.cacheattributes.UseMemoryShrinker=false jcs.region.testCache1.cacheattributes.MaxMemoryIdleTimeSeconds=3600 jcs.region.testCache1.cacheattributes.ShrinkerIntervalSeconds=60 jcs.region.testCache1.cacheattributes.MaxSpoolPerRun=500 jcs.region.testCache1.elementattributes=org.apache.jcs.engine.ElementAtt ributes jcs.region.testCache1.elementattributes.IsEternal=false jcs.region.testCache1.elementattributes.IsSpool=false jcs.region.testCache1.elementattributes.IsRemote=false jcs.region.testCache1.elementattributes.IsLateral=false jcs.region.testCache1.elementattributes.IdleTime=1800 jcs.region.testCache1.elementattributes.MaxLifeSeconds=21600
