# CACHE IN MEMORY## If you want to disable memory caching, just uncomment this line.## cache.memory=false# CACHE KEY## This is the key that will be used to store the cache in the application# and session scope.## If you want to set the cache key to anything other than the default# uncomment this line and change the cache.key## cache.key=__oscache_cache# USE HOST DOMAIN NAME IN KEY## Servers for multiple host domains may wish to add host name info to# the generation of the key. If this is true, then uncomment the# following line.## cache.use.host.domain.in.key=true# CACHE LISTENERS## These hook OSCache events and perform various actions such as logging# cache hits and misses, or broadcasting to other cache instances across a cluster.# See the documentation for further information.#cache.event.listeners= com.opensymphony.oscache.plugins.clustersupport.JavaGroupsBroadcastingListener,\ com.opensymphony.oscache.extra.CacheEntryEventListenerImpl,\ com.opensymphony.oscache.extra.CacheMapAccessEventListenerImpl,\ com.opensymphony.oscache.extra.ScopeEventListenerImpl,\ com.opensymphony.oscache.extra.StatisticListenerImpl# CACHE PERSISTENCE CLASS## Specify the class to use for persistence. If you use the supplied DiskPersistenceListener,# don't forget to supply the cache.path property to specify the location of the cache# directory.# # If a persistence class is not specified, OSCache will use memory caching only.#cache.persistence.class=com.opensymphony.oscache.plugins.diskpersistence.DiskPersistenceListener# cache.persistence.class=com.opensymphony.oscache.plugins.diskpersistence.HashDiskPersistenceListener# CACHE OVERFLOW PERSISTENCE# Use persistent cache in overflow or not. The default value is false, which means# the persistent cache will be used at all times for every entry. true is the recommended setting.#cache.persistence.overflow.only=true# CACHE DIRECTORY## This is the directory on disk where caches will be stored by the DiskPersistenceListener.# it will be created if it doesn't already exist. Remember that OSCache must have# write permission to this directory.## Note: for Windows machines, this needs \ to be escaped# ie Windows:# cache.path=c:\\myapp\\cache# or *ix:cache.path=/opt/cache## cache.path=c:\\app\\cache# CACHE ALGORITHM## Default cache algorithm to use. Note that in order to use an algorithm# the cache size must also be specified. If the cache size is not specified,# the cache algorithm will be Unlimited cache.#cache.algorithm=com.opensymphony.oscache.base.algorithm.LRUCache# cache.algorithm=com.opensymphony.oscache.base.algorithm.FIFOCache# cache.algorithm=com.opensymphony.oscache.base.algorithm.UnlimitedCache# THREAD BLOCKING BEHAVIOR## When a request is made for a stale cache entry, it is possible that another thread is already# in the process of rebuilding that entry. This setting specifies how OSCache handles the# subsequent 'non-building' threads. The default behaviour (cache.blocking=false) is to serve# the old content to subsequent threads until the cache entry has been updated. This provides# the best performance (at the cost of serving slightly stale data). When blocking is enabled,# threads will instead block until the new cache entry is ready to be served. Once the new entry# is put in the cache the blocked threads will be restarted and given the new entry.# Note that even if blocking is disabled, when there is no stale data available to be served# threads will block until the data is added to the cache by the thread that is responsible# for building the data.##cache.blocking=true# CACHE SIZE## Default cache size in number of items. If a size is specified but not# an algorithm, the cache algorithm used will be LRUCache.#cache.capacity=1000# CACHE UNLIMITED DISK# Use unlimited disk cache or not. The default value is false, which means# the disk cache will be limited in size to the value specified by cache.capacity.## cache.unlimited.disk=false# JMS CLUSTER PROPERTIES## Configuration properties for JMS clustering. See the clustering documentation# for more information on these settings.##cache.cluster.jms.topic.factory=java:comp/env/jms/TopicConnectionFactory#cache.cluster.jms.topic.name=java:comp/env/jms/OSCacheTopic#cache.cluster.jms.node.name=node1# JAVAGROUPS CLUSTER PROPERTIES## Configuration properites for the JavaGroups clustering. Only one of these# should be specified. Default values (as shown below) will be used if niether# property is set. See the clustering documentation and the JavaGroups project# (www.javagroups.com) for more information on these settings.##Jason Cheng Added#The default value is 231.12.21.132, however you can use any class D IP address. #Class D address fall in the range 224.0.0.0 through 239.255.255.255# If your cache is binding# to 127.0.0.1 and not to a network ip. Your cache must be listening on a# network ip to talk to other servers. You can test the clustered cache by# running two portals on two machines. Do not attempt to run both portals on# one machine because the multicast will not know to loopback.cache.cluster.properties=UDP(mcast_addr=231.12.21.136;mcast_port=45566;ip_ttl=32;\mcast_send_buf_size=150000;mcast_recv_buf_size=80000):\PING(timeout=2000;num_initial_members=3):\MERGE2(min_interval=5000;max_interval=10000):\FD_SOCK:VERIFY_SUSPECT(timeout=1500):\pbcast.NAKACK(gc_lag=50;retransmit_timeout=300,600,1200,2400,4800;max_xmit_size=8192):\UNICAST(timeout=300,600,1200,2400):\pbcast.STABLE(desired_avg_gossip=20000):\FRAG(frag_size=8096;down_thread=false;up_thread=false):\pbcast.GMS(join_timeout=5000;join_retry_timeout=2000;shun=false;print_local_addr=true)#cache.cluster.multicast.ip=231.12.21.132
