Description

We declared a region with a TCP Lateral cache auxiliary with two separate servers. The connection to the JCS is done from a web service implementation (axis2) method.
If the two Tomcats on the two machines are working than everything works fine. When one Tomcat update the cache it is seen also on the other Tomcat.
Now the issue arises when I restart one of the Tomcats . Than it loses all cache elements and if I make a get to an element that exists in the other TOmcat I get a null. Also on JCSAdmin there is no elements on the cache.
We tried to change the allowGet flag to True but it stopped the mutual update of new elements.
We know we are missing here something . Can you guide us?
Here is the cache.ccf file:

1. DEFAULT CACHE REGION

1. sets the default aux value for any non configured caches
   jcs.default=
   jcs.default.cacheattributes=org.apache.jcs.engine.CompositeCacheAttributes
   jcs.default.cacheattributes.MaxObjects=1000
   #jcs.default.cacheattributes.MemoryCacheName=org.apache.jcs.engine.memory.lru.LRUMemoryCache
   jcs.default.elementattributes.IsEternal=false
   jcs.default.elementattributes.MaxLifeSeconds=3600
   jcs.default.elementattributes.IdleTime=1800
   jcs.default.elementattributes.IsSpool=true
   jcs.default.elementattributes.IsRemote=true
   jcs.default.elementattributes.IsLateral=true

1. CACHE REGIONS AVAILABLE

jcs.region.loginProfileCache=LTCP
jcs.region.loginProfileCache.cacheattributes=org.apache.jcs.engine.CompositeCacheAttributes
jcs.region.loginProfileCache.cacheattributes.MaxObjects=100
jcs.region.loginProfileCache.cacheattributes.MemoryCacheName=org.apache.jcs.engine.memory.lru.LRUMemoryCache
jcs.region.loginProfileCache.elementattributes.IsEternal=true
jcs.region.loginProfileCache.elementattributes.MaxLifeSeconds=1800
jcs.region.loginProfileCache.elementattributes.IdleTime=1800
jcs.region.loginProfileCache.elementattributes.IsSpool=true
jcs.region.loginProfileCache.elementattributes.IsRemote=true
jcs.region.loginProfileCache.elementattributes.IsLateral=true

1. AUXILIARY CACHES AVAILABLE

1. Remote RMI Cache set up to failover
   jcs.auxiliary.RFailover=org.apache.jcs.auxiliary.remote.RemoteCacheFactory
   jcs.auxiliary.RFailover.attributes=org.apache.jcs.auxiliary.remote.RemoteCacheAttributes
   #jcs.auxiliary.RFailover.attributes.RemoteTypeName=LOCAL
   jcs.auxiliary.RC.attributes.RemoveUponRemotePut=false
   jcs.auxiliary.RFailover.attributes.FailoverServers=localhost:1102,localhost:1103
   jcs.auxiliary.RFailover.attributes.GetOnly=false

#LTCP non_UDP Discovery Configuration

jcs.auxiliary.LTCP=org.apache.jcs.auxiliary.lateral.socket.tcp.LateralTCPCacheFactory
jcs.auxiliary.LTCP.attributes=org.apache.jcs.auxiliary.lateral.socket.tcp.TCPLateralCacheAttributes
jcs.auxiliary.LTCP.attributes.UdpDiscoveryEnabled=false
jcs.auxiliary.LTCP.attributes.tcpServers=172.16.1.120:1110
jcs.auxiliary.LTCP.attributes.tcpListenerPort=1110
jcs.auxiliary.LTCP.attributes.allowGet=false

1. Primary Disk Cache – faster than the rest because of memory key storage
   jcs.auxiliary.DC=org.apache.jcs.auxiliary.disk.indexed.IndexedDiskCacheFactory
   jcs.auxiliary.DC.attributes=org.apache.jcs.auxiliary.disk.indexed.IndexedDiskCacheAttributes
   jcs.auxiliary.DC.attributes.DiskPath=C:/D_DISK/Temp/larisa/profileCashe
   jcs.auxiliary.DC.attributes.MaxPurgatorySize=10000
   jcs.auxiliary.DC.attributes.MaxKeySize=10000
   jcs.auxiliary.DC.attributes.OptimizeAtRemoveCount=300000
   jcs.auxiliary.DC.attributes.MaxRecycleBinSize=7500
