Import jars: jgroups-all.jar [JGroups-2.6.3] oscache-2.4.1.jar Configuration oscache.properties # 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 web.xml configuraion for the jsp cache: <!-- OSCache Configuration --> <filter> <filter-name>CacheFilterStaticContent</filter-name> <filter-class> com.opensymphony.oscache.web.filter.CacheFilter </filter-class> <init-param> <param-name>expires</param-name> <param-value>time</param-value> </init-param> </filter> <!-- The mapping for the OSCache --> <filter-mapping> <filter-name>CacheFilterStaticContent</filter-name> <url-pattern>*.jsp</url-pattern> </filter-mapping> 声明:ITeye文章版权属于作者,受法律保护。没有作者书面许可不得转载。
