Erik, Hazelcast is not a replicated cache by default, just distributed. I understand there is a backup/restore system but you would need at least three servers to test it.
The only config I have are these: cluster.members cluster.instanceName crypto.signing.key crypto.encryption.key crypto.enabled=true which is in a shared file. I have two cas'es running on my local and have not seen that error. You can tell if the hazelcast servers are communicating if your tickets are validated on a different server than they were created. Set the load balancer to round robin. I do not see a cas property for replication. Is it an option for cas? See hazelcast docs, https://docs.hazelcast.com/imdg/4.1/data-structures/replicated-map.html Ray On Thu, 2021-07-01 at 19:41 +0000, 'Mallory, Erik' via CAS Community wrote: Notice: This message was sent from outside the University of Victoria email system.

All I'm having a problem implementing the Hazelcast ticket store in CAS 6.3.4 which uses hazelcast-4.1 Currently I'm testing with a two node cluster fontended with a netscaler. Each node has it's own /etc/cas/config/cas.properties so each node as it's own hazelcast configuration. Here is the relevant hazelcast configuration parameters: cas.ticket.registry.hazelcast.page-size=500 cas.ticket.registry.hazelcast.cluster.tcpip-enabled=true cas.ticket.registry.hazelcast.cluster.map-merge-policy=PUT_IF_ABSENT cas.ticket.registry.hazelcast.cluster.instance-name=cas-dev cas.ticket.registry.hazelcast.cluster.members=10.0.79.38,10.0.79.37 cas.ticket.registry.hazelcast.cluster.eviction-policy=LRU cas.ticket.registry.hazelcast.cluster.max-no-heartbeat-seconds=300 cas.ticket.registry.hazelcast.cluster.logging-type=slf4j cas.ticket.registry.hazelcast.cluster.port=5701 cas.ticket.registry.hazelcast.cluster.max-size=85 cas.ticket.registry.hazelcast.cluster.backup-count=1 cas.ticket.registry.hazelcast.cluster.async-backup-count=0 cas.ticket.registry.hazelcast.cluster.max-size- policy=USED_HEAP_PERCENTAGE cas.ticket.registry.hazelcast.cluster.timeout=5 IN my testing I found that the tickets were not being replicated the other host. I'd use the netscaler to switch between the backend CAS nodes, log in to one, fail over to the other node and attempt to access cas, and I was redirected to the login screen. After restarting the cas services on both nodes and tailing out the cas log I noticed the following error: Cannot add a dynamic configuration 'MapConfig{name='serviceTicketsCache', inMemoryFormat=BINARY', metadataPolicy=CREATE_ON_ UPDATE, backupCount=1, asyncBackupCount=0, timeToLiveSeconds=0, maxIdleSeconds=500, readBackupData=false, evictionConfig=Evict ionConfig{size=85, maxSizePolicy=USED_HEAP_PERCENTAGE, evictionPolicy=LRU, comparatorClassName=null, comparator=null}, merkleT ree=MerkleTreeConfig{enabled=false, depth=10}, eventJournal=EventJournalConfig{enabled=false, capacity=10000, timeToLiveSecond s=0}, hotRestart=HotRestartConfig{enabled=false, fsync=false}, nearCacheConfig=null, mapStoreConfig=MapStoreConfig{enabled=fal se, className='null', factoryClassName='null', writeDelaySeconds=0, writeBatchSize=1, implementation=null, factoryImplementation=null, properties={}, initialLoadMode=LAZY, writeCoalescing=true}, mergePolicyConfig=MergePolicyConfig{policy='com.hazelcast.spi.merge.Lat estUpdateMergePolicy', batchSize=100}, wanReplicationRef=null, entryListenerConfigs=null, indexConfigs=null, attributeConfigs=null, splitBrainProtectionName=null, queryCacheConfigs=null, cacheDeserializedValues=INDEX_ONLY}' as there is already a conflicting configuration 'MapConfig{name='serviceTicketsCache', inMemoryFormat=BINARY', metadataPolicy=CREATE_ON_UPDATE, backupCount=1, asyncBackupCount=0, timeToLiveSeconds=0, maxIdleSeconds=10, readBackupData=false, evictionConfig=EvictionConfig{size=85, maxSizePolicy=USED_HEAP_PERCENTAGE, evictionPolicy=LRU, comparatorClassName=null, comparator=null}, merkleTree=MerkleTreeConfig{enabled=false, depth=10}, eventJournal=EventJournalConfig{enabled=false, capacity=10000, timeToLiveSeconds=0}, hotRestart=HotRestartConfig{enabled=false, fsync=false}, nearCacheConfig=null, mapStoreConfig=MapStoreConfig{enabled=false, className='null', factoryClassName='null', writeDelaySeconds=0, writeBatchSize=1, implementation=null, factoryImplementation=null, properties={}, initialLoadMode=LAZY, writeCoalescing=true}, mergePolicyConfig=MergePolicyConfig{policy='com.hazelcast.spi.merge.Lat estUpdateMergePolicy', batchSize=100}, wanReplicationRef=null, entryListenerConfigs=null, indexConfigs=null, attributeConfigs=null, splitBrainProtectionName=null, queryCacheConfigs=null, cacheDeserializedValues=INDEX_ONLY}'> So off to google I go and I find <https://github.com/hazelcast/hazelcast/issues/12222> https://github.com/hazelcast/hazelcast/issues/12222 and I add -Dhazelcast.dynamicconfig.ignore.conflicts=true for giggles and to see something at least boot. So now both services start up but I'm ignoring the dynamic config conflicts. My testing fails it would appear that hazelcast is not able to share the tgt between nodes.
