Hi, we're experiencing some difficulty getting JCS (3.2) remote RMI cache to work properly. I'm having trouble finding a full working example of the remote RMI cache setup. I'd appreciate it if someone could point me in the right direction. Thank you! -Greg
1. Our clients are initiating 2 PUTs in quick succession. The server recognizes both, but only stores the first. I'm seeing the following in the remote server log, for the second PUT (note the "remove node" statement which does not occur during the first PUT)- DEBUG | [RMI TCP Connection(138)-192.168.2.100] log.Log4j2LogAdapter (Log4j2LogAdapter.java:57) - In update, put [key1] in [cache2] DEBUG | [RMI TCP Connection(138)-192.168.2.100] log.Log4j2LogAdapter (Log4j2LogAdapter.java:112) - In update, requesterId = [7] fromCluster = false DEBUG | [RMI TCP Connection(138)-192.168.2.100] log.Log4j2LogAdapter (Log4j2LogAdapter.java:112) - Put NOT from cluster, updating other auxiliaries for region. requesterId [7] DEBUG | [RMI TCP Connection(138)-192.168.2.100] log.Log4j2LogAdapter (Log4j2LogAdapter.java:55) - Updating memory cache key1 DEBUG | [RMI TCP Connection(138)-192.168.2.100] log.Log4j2LogAdapter (Log4j2LogAdapter.java:89) - removing node 1. When a client initiates a REMOVE, the remote server recognizes and removes its own inmem entry, but that event does not appear to be broadcast to the OTHER clients. This results in the other clients being out of sync with the remote server. Setup/Config details- The cache server is running within the same app server (Wildfly) as the clients. There are 2 cache regions configured in the clients. In our code, we're using CacheAccess<String, CustomValue>, where CustomValue class is fully serializable. The client config is as follows- # ################# CLIENT CONFIG ##################### jcs.default=RC jcs.default.cacheattributes=org.apache.commons.jcs3.engine.CompositeCacheAttributes jcs.default.cacheattributes.MaxObjects=1000 jcs.default.cacheattributes.MemoryCacheName=org.apache.commons.jcs3.engine.memory.lru.LRUMemoryCache jcs.default.cacheattributes.UseMemoryShrinker=true jcs.default.cacheattributes.MaxMemoryIdleTimeSeconds=3600 jcs.default.cacheattributes.ShrinkerIntervalSeconds=60 jcs.default.elementattributes=org.apache.commons.jcs3.engine.ElementAttributes jcs.default.elementattributes.IsEternal=false jcs.default.elementattributes.MaxLife=700 jcs.default.elementattributes.IdleTime=1800 jcs.default.elementattributes.IsSpool=true jcs.default.elementattributes.IsRemote=true jcs.default.elementattributes.IsLateral=true jcs.region.cache1=RC jcs.region.cache2=RC jcs.auxiliary.RC=org.apache.commons.jcs3.auxiliary.remote.RemoteCacheFactory jcs.auxiliary.RC.attributes=org.apache.commons.jcs3.auxiliary.remote.RemoteCacheAttributes jcs.auxiliary.RC.attributes.FailoverServers=localhost:1101 jcs.auxiliary.RC.attributes.LocalPort=1102 jcs.auxiliary.RC.attributes.RemoveUponRemotePut=false jcs.auxiliary.RC.attributes.GetTimeoutMillis=-1 jcs.auxiliary.RC.attributes.GetOnly=false jcs.auxillary.RC.cacheeventlogger=org.apache.commons.jcs3.engine.logging.CacheEventLoggerDebugLogger jcs.auxillary.RC.cacheeventlogger.attributes.logCategoryName=RCEventLogCategory The remote server config is as follows- # ################# REMOTE SERVER CONFIG ##################### # Registry used to register and provide the IRmiCacheService service. registry.host=localhost registry.port=1101 # call back port to local caches. jcs.remotecache.serverattributes.servicePort=1102 # cluster setting jcs.remotecache.serverattributes.LocalClusterConsistency=true jcs.remotecache.serverattributes.RemoveUponRemotePut=false jcs.remotecache.cacheeventlogger=org.apache.commons.jcs3.engine.logging.CacheEventLoggerDebugLogger jcs.remotecache.cacheeventlogger.attributes.logCategoryName=RCEventLogCategory # ############################################################# # ################# DEFAULT CACHE REGION ##################### # sets the default aux value for any non configured caches jcs.default= jcs.default.cacheattributes=org.apache.commons.jcs3.engine.CompositeCacheAttributes jcs.default.cacheattributes.MaxObjects=200000 jcs.default.cacheattributes.MemoryCacheName=org.apache.commons.jcs3.engine.memory.lru.LRUMemoryCache jcs.default.cacheattributes.UseMemoryShrinker=true jcs.default.cacheattributes.MaxMemoryIdleTimeSeconds=3600 jcs.default.cacheattributes.ShrinkerIntervalSeconds=60 jcs.default.cacheattributes.ShrinkerIntervalSeconds=60 jcs.default.elementattributes=org.apache.commons.jcs3.engine.ElementAttributes jcs.default.elementattributes.IsEternal=false jcs.default.elementattributes.MaxLife=7000 jcs.default.elementattributes.IdleTime=1800 jcs.default.elementattributes.IsSpool=true jcs.default.elementattributes.IsRemote=true jcs.default.elementattributes.IsLateral=true jcs.region.cache1= jcs.region.cache2=
