+/**
+ * A cache server which exposes available cache operations remotely through RMI.
+ * <p/>
+ * It acts as a Decorator to a Cache. It holds an instance of cache, which is a local cache it talks to.
+ * <p/>
+ * This class could specify a security manager with code like:
+ * <pre>
+ * if (System.getSecurityManager() == null) {
+ * System.setSecurityManager(new RMISecurityManager());
+ * }
+ * </pre>
+ * Doing so would require the addition of <code>grant</code> statements in the <code>java.policy</code> file.
+ * <p/>
+ * Per the JDK documentation: "If no security manager is specified no class loading, by RMI clients or servers, is allowed,
+ * aside from what can be found in the local CLASSPATH." The classpath of each instance of this class should have
+ * all required classes to enable distribution, so no remote classloading is required or desirable. Accordingly,
+ * no security manager is set and there are no special JVM configuration requirements.
+ * <p/>
+ * This class opens a ServerSocket. The dispose method should be called for orderly closure of that socket. This class
+ * has a shutdown hook which calls dispose() as a convenience feature for developers.

+CacheManager Configuration
+==========================
+An ehcache.xml corresponds to a single CacheManager.
+
+See instructions below or the ehcache schema (ehcache.xsd) on how to configure.
+
+System property tokens can be specified in this file which are replaced when the configuration
+is loaded. For example multicastGroupPort=${multicastGroupPort} can be replaced with the
+System property either from an environment variable or a system property specified with a
+command line switch such as -DmulticastGroupPort=4446.
+
+The attributes of <ehcache> are:
+* name - an optional name for the CacheManager. The name is optional and primarily used
+for documentation or to distinguish Terracotta clustered cache state. With Terracotta
+clustered caches, a combination of CacheManager name and cache name uniquely identify a
+particular cache store in the Terracotta clustered memory.
+* updateCheck - an optional boolean flag specifying whether this CacheManager should check
+for new versions of Ehcache over the Internet. If not specified, updateCheck="true".
+* monitoring - an optional setting that determines whether the CacheManager should
+automatically register the SampledCacheMBean with the system MBean server.
+
+Currently, this monitoring is only useful when using Terracotta clustering and using the
+Terracotta Developer Console. With the "autodetect" value, the presence of Terracotta clustering
+will be detected and monitoring, via the Developer Console, will be enabled. Other allowed values
+are "on" and "off". The default is "autodetect". This setting does not perform any function when
+used with JMX monitors.
+-->
+<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

+
+ <!--
+ DiskStore configuration
+ =======================
+
+ The diskStore element is optional. To turn off disk store path creation, comment out the diskStore
+ element below.
+
+ Configure it if you have overflowToDisk or diskPersistent enabled for any cache.
+
+ If it is not configured, and a cache is created which requires a disk store, a warning will be
+ issued and java.io.tmpdir will automatically be used.
+
+ diskStore has only one attribute - "path". It is the path to the directory where
+ .data and .index files will be created.
+
+ If the path is one of the following Java System Property it is replaced by its value in the
+ running VM. For backward compatibility these are not specified without being enclosed in the ${token}
+ replacement syntax.
+
+ The following properties are translated:
+ * user.home - User's home directory
+ * user.dir - User's current working directory
+ * java.io.tmpdir - Default temp file path
+ * ehcache.disk.store.dir - A system property you would normally specify on the command line
+ e.g. java -Dehcache.disk.store.dir=/u01/myapp/diskdir ...
+
+ Subdirectories can be specified below the property e.g. java.io.tmpdir/one
+
+ -->

+ CacheManagerEventListener
+ =========================
+ Specifies a CacheManagerEventListenerFactory which is notified when Caches are added

+
+ The attributes of CacheManagerEventListenerFactory are:
+ * class - a fully qualified factory class name
+ * properties - comma separated properties having meaning only to the factory.
+
+ Sets the fully qualified class name to be registered as the CacheManager event listener.
+
+ The events include:
+ * adding a Cache
+ * removing a Cache
+
+ Callbacks to listener methods are synchronous and unsynchronized. It is the responsibility
+ of the implementer to safely handle the potential performance and thread safety issues
+ depending on what their listener is doing.
+
+ If no class is specified, no listener is created. There is no default.
+ -->
+ <cacheManagerEventListenerFactory class="" properties=""/>
+
+
+ <!--
+ CacheManagerPeerProvider
+ ========================
+ (For distributed operation)
+
+ Specifies a CacheManagerPeerProviderFactory which will be used to create a
+ CacheManagerPeerProvider, which discovers other CacheManagers in the cluster.
+
+ One or more providers can be configured. The first one in the ehcache.xml is the default, which is used
+ for replication and bootstrapping.
+
+ The attributes of cacheManagerPeerProviderFactory are:
+ * class - a fully qualified factory class name
+ * properties - comma separated properties having meaning only to the factory.
+
+ Providers are available for RMI, JGroups and JMS as shown following.
+
+ RMICacheManagerPeerProvider
+ +++++++++++++++++++++++++++
+
+ Ehcache comes with a built-in RMI-based distribution system with two means of discovery of
+ CacheManager peers participating in the cluster:
+ * automatic, using a multicast group. This one automatically discovers peers and detects
+ changes such as peers entering and leaving the group
+ * manual, using manual rmiURL configuration. A hardcoded list of peers is provided at
+ configuration time.
+
+ Configuring Automatic Discovery:
+ Automatic discovery is configured as per the following example:
+ <cacheManagerPeerProviderFactory
+ class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
+ properties="hostName=fully_qualified_hostname_or_ip,
+ peerDiscovery=automatic, multicastGroupAddress=230.0.0.1,
+ multicastGroupPort=4446, timeToLive=32"/>
+
+ Valid properties are:
+ * peerDiscovery (mandatory) - specify "automatic"
+ * multicastGroupAddress (mandatory) - specify a valid multicast group address
+ * multicastGroupPort (mandatory) - specify a dedicated port for the multicast heartbeat
+ traffic
+ * timeToLive - specify a value between 0 and 255 which determines how far the packets will
+ propagate.
+
+ By convention, the restrictions are:
+ 0 - the same host
+ 1 - the same subnet
+ 32 - the same site
+ 64 - the same region
+ 128 - the same continent
+ 255 - unrestricted
+
+ * hostName - the hostname or IP of the interface to be used for sending and receiving multicast packets
+ (relevant to mulithomed hosts only)
+
+ Configuring Manual Discovery:
+ Manual discovery requires a unique configuration per host. It is contains a list of rmiURLs for the peers, other
+ than itself. So, if we have server1, server2 and server3 the configuration will be:
+
+ In server1's configuration:
+ <cacheManagerPeerProviderFactory class=
+ "net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
+ properties="peerDiscovery=manual,
+ rmiUrls=//server2:40000/sampleCache1|//server3:40000/sampleCache1
+ | //server2:40000/sampleCache2|//server3:40000/sampleCache2"
+ propertySeparator="," />
+
+ In server2's configuration:
+ <cacheManagerPeerProviderFactory class=
+ "net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
+ properties="peerDiscovery=manual,
+ rmiUrls=//server1:40000/sampleCache1|//server3:40000/sampleCache1
+ | //server1:40000/sampleCache2|//server3:40000/sampleCache2"
+ propertySeparator="," />
+
+ In server3's configuration:
+ <cacheManagerPeerProviderFactory class=
+ "net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
+ properties="peerDiscovery=manual,
+ rmiUrls=//server1:40000/sampleCache1|//server2:40000/sampleCache1
+ | //server1:40000/sampleCache2|//server2:40000/sampleCache2"
+ propertySeparator="," />
+
+
+ Valid properties are:
+ * peerDiscovery (mandatory) - specify "manual"
+ * rmiUrls (mandatory) - specify a pipe separated list of rmiUrls, in the form
+ //hostname:port
+ * hostname (optional) - the hostname is the hostname of the remote CacheManager peer. The port is the listening
+ port of the RMICacheManagerPeerListener of the remote CacheManager peer.
+
+ JGroupsCacheManagerPeerProvider
+ +++++++++++++++++++++++++++++++
+ <cacheManagerPeerProviderFactory class="net.sf.ehcache.distribution.jgroups.JGroupsCacheManagerPeerProviderFactory"
+ properties="connect=UDP(mcast_addr=231.12.21.132;mcast_port=45566;ip_ttl=32;
+ mcast_send_buf_size=150000;mcast_recv_buf_size=80000):

+ FRAG:
+ pbcast.GMS(join_timeout=5000;join_retry_timeout=2000;shun=false;print_local_addr=false)"
+ propertySeparator="::"
+ />
+ The only property necessary is the connect String used by jgroups to configure itself. Refer to the Jgroups documentation for explanation
+ of all the protocols. The example above uses UDP multicast. If the connect property is not specified the default JGroups connection will be
+ used.
+
+
+ JMSCacheManagerPeerProviderFactory
+ ++++++++++++++++++++++++++++++++++
+ <cacheManagerPeerProviderFactory
+ class="net.sf.ehcache.distribution.jms.JMSCacheManagerPeerProviderFactory"
+ properties="..."
+ propertySeparator=","
+ />
+
+ The JMS PeerProviderFactory uses JNDI to maintain message queue independence. Refer to the manual for full configuration
+ examples using ActiveMQ and Open Message Queue.
+
+ Valid properties are:
+ * initialContextFactoryName (mandatory) - the name of the factory used to create the message queue initial context.
+ * providerURL (mandatory) - the JNDI configuration information for the service provider to use.
+ * topicConnectionFactoryBindingName (mandatory) - the JNDI binding name for the TopicConnectionFactory
+ * topicBindingName (mandatory) - the JNDI binding name for the topic name
+ * getQueueBindingName (mandatory only if using jmsCacheLoader) - the JNDI binding name for the queue name
+ * securityPrincipalName - the JNDI java.naming.security.principal
+ * securityCredentials - the JNDI java.naming.security.credentials
+ * urlPkgPrefixes - the JNDI java.naming.factory.url.pkgs
+ * userName - the user name to use when creating the TopicConnection to the Message Queue
+ * password - the password to use when creating the TopicConnection to the Message Queue
+ * acknowledgementMode - the JMS Acknowledgement mode for both publisher and subscriber. The available choices are
+ AUTO_ACKNOWLEDGE, DUPS_OK_ACKNOWLEDGE and SESSION_TRANSACTED. The default is AUTO_ACKNOWLEDGE.

+
+ Ehcache comes with a built-in RMI-based distribution system. The listener component is

+ port=40001,
+ remoteObjectPort=40002,
+ socketTimeoutMillis=120000"
+ propertySeparator="," />
+
+ All properties are optional. They are:
+ * hostName - the hostName of the host the listener is running on. Specify
+ where the host is multihomed and you want to control the interface over which cluster
+ messages are received. Defaults to the host name of the default interface if not
+ specified.
+ * port - the port the RMI Registry listener listens on. This defaults to a free port if not specified.
+ * remoteObjectPort - the port number on which the remote objects bound in the registry receive calls.
+ This defaults to a free port if not specified.
+ * socketTimeoutMillis - the number of ms client sockets will stay open when sending
+ messages to the listener. This should be long enough for the slowest message.
+ If not specified it defaults to 120000ms.

+ TerracottaConfig
+ ========================
+ (Enable for Terracotta clustered operation)
+

+ To specify a reference to a source (or sources) of configuration, use the url
+ attribute. The url attribute must contain a comma-separated list of:
+ * path to Terracotta configuration file (usually named tc-config.xml)
+ * URL to Terracotta configuration file
+ * <server host>:<port> of running Terracotta Server instance
+
+ Simplest example for pointing to a Terracotta server on this machine:
+ <terracottaConfig url="localhost:9510"/>
+
+ Example using a path to Terracotta configuration file:
+ <terracottaConfig url="/app/config/tc-config.xml"/>
+
+ Example using a URL to a Terracotta configuration file:
+ <terracottaConfig url="http://internal/ehcache/app/tc-config.xml"/>
+
+ Example using multiple Terracotta server instance URLs (for fault tolerance):
+ <terracottaConfig url="host1:9510,host2:9510,host3:9510"/>
+
+ To embed a Terracotta configuration file within the ehcache configuration, simply
+ place a normal Terracotta XML config within the <terracottaConfig> element.
+
+ Example:
+ <terracottaConfig>
+ <tc-config>
+ <servers>
+ <server host="server1" name="s1"/>
+ <server host="server2" name="s2"/>
+ </servers>
+ <clients>
+ <logs>app/logs-%i</logs>
+ </clients>
+ </tc-config>
+ </terracottaConfig>
+
+ For more information on the Terracotta configuration, see the Terracotta documentation.

+ <!--
+ Cache configuration
+ ===================
+
+ The following attributes are required.
+
+ name:
+ Sets the name of the cache. This is used to identify the cache. It must be unique.
+
+ maxElementsInMemory:
+ Sets the maximum number of objects that will be created in memory
+
+ maxElementsOnDisk:
+ Sets the maximum number of objects that will be maintained in the DiskStore
+ The default value is zero, meaning unlimited.
+
+ eternal:
+ Sets whether elements are eternal. If eternal, timeouts are ignored and the
+ element is never expired.
+
+ overflowToDisk:
+ Sets whether elements can overflow to disk when the memory store
+ has reached the maxInMemory limit.
+
+ The following attributes and elements are optional.
+
+ timeToIdleSeconds:
+ Sets the time to idle for an element before it expires.
+ i.e. The maximum amount of time between accesses before an element expires
+ Is only used if the element is not eternal.
+ Optional attribute. A value of 0 means that an Element can idle for infinity.
+ The default value is 0.
+
+ timeToLiveSeconds:
+ Sets the time to live for an element before it expires.
+ i.e. The maximum time between creation time and when an element expires.
+ Is only used if the element is not eternal.
+ Optional attribute. A value of 0 means that and Element can live for infinity.
+ The default value is 0.
+
+ diskPersistent:
+ Whether the disk store persists between restarts of the Virtual Machine.
+ The default value is false.
+
+ diskExpiryThreadIntervalSeconds:
+ The number of seconds between runs of the disk expiry thread. The default value
+ is 120 seconds.
+
+ diskSpoolBufferSizeMB:
+ This is the size to allocate the DiskStore for a spool buffer. Writes are made
+ to this area and then asynchronously written to disk. The default size is 30MB.
+ Each spool buffer is used only by its cache. If you get OutOfMemory errors consider
+ lowering this value. To improve DiskStore performance consider increasing it. Trace level
+ logging in the DiskStore will show if put back ups are occurring.
+
+ clearOnFlush:
+ whether the MemoryStore should be cleared when flush() is called on the cache.
+ By default, this is true i.e. the MemoryStore is cleared.
+
+ memoryStoreEvictionPolicy:
+ Policy would be enforced upon reaching the maxElementsInMemory limit. Default
+ policy is Least Recently Used (specified as LRU). Other policies available -
+ First In First Out (specified as FIFO) and Less Frequently Used
+ (specified as LFU)
+
+ Cache elements can also contain sub elements which take the same format of a factory class
+ and properties. Defined sub-elements are:
+
+ * cacheEventListenerFactory - Enables registration of listeners for cache events, such as
+ put, remove, update, and expire.
+
+ * bootstrapCacheLoaderFactory - Specifies a BootstrapCacheLoader, which is called by a
+ cache on initialisation to prepopulate itself.
+
+ * cacheExtensionFactory - Specifies a CacheExtension, a generic mechansim to tie a class
+ which holds a reference to a cache to the cache lifecycle.
+
+ * cacheExceptionHandlerFactory - Specifies a CacheExceptionHandler, which is called when
+ cache exceptions occur.
+
+ * cacheLoaderFactory - Specifies a CacheLoader, which can be used both asynchronously and
+ synchronously to load objects into a cache. More than one cacheLoaderFactory element
+ can be added, in which case the loaders form a chain which are executed in order. If a
+ loader returns null, the next in chain is called.
+
+
+ RMI Cache Replication
+ +++++++++++++++++++++
+
+ Each cache that will be distributed needs to set a cache event listener which replicates
+ messages to the other CacheManager peers. For the built-in RMI implementation this is done
+ by adding a cacheEventListenerFactory element of type RMICacheReplicatorFactory to each
+ distributed cache's configuration as per the following example:
+
+ <cacheEventListenerFactory class="net.sf.ehcache.distribution.RMICacheReplicatorFactory"
+ properties="replicateAsynchronously=true,
+ replicatePuts=true,
+ replicatePutsViaCopy=false,
+ replicateUpdates=true,
+ replicateUpdatesViaCopy=true,
+ replicateRemovals=true
+ asynchronousReplicationIntervalMillis=<number of milliseconds"
+ propertySeparator="," />
+
+ The RMICacheReplicatorFactory recognises the following properties:
+
+ * replicatePuts=true|false - whether new elements placed in a cache are
+ replicated to others. Defaults to true.
+
+ * replicatePutsViaCopy=true|false - whether the new elements are
+ copied to other caches (true), or whether a remove message is sent. Defaults to true.
+
+ * replicateUpdates=true|false - whether new elements which override an
+ element already existing with the same key are replicated. Defaults to true.
+
+ * replicateRemovals=true - whether element removals are replicated. Defaults to true.
+
+ * replicateAsynchronously=true | false - whether replications are
+ asynchronous (true) or synchronous (false). Defaults to true.
+
+ * replicateUpdatesViaCopy=true | false - whether the new elements are
+ copied to other caches (true), or whether a remove message is sent. Defaults to true.
+
+ * asynchronousReplicationIntervalMillis=<number of milliseconds> - The asynchronous
+ replicator runs at a set interval of milliseconds. The default is 1000. The minimum
+ is 10. This property is only applicable if replicateAsynchronously=true
+
+
+ JGroups Replication
+ +++++++++++++++++++
+
+ For the Jgroups replication this is done with:
+ <cacheEventListenerFactory class="net.sf.ehcache.distribution.jgroups.JGroupsCacheReplicatorFactory"
+ properties="replicateAsynchronously=true, replicatePuts=true,
+ replicateUpdates=true, replicateUpdatesViaCopy=false,
+ replicateRemovals=true,asynchronousReplicationIntervalMillis=1000"/>
+ This listener supports the same properties as the RMICacheReplicationFactory.
+
+
+ JMS Replication
+ +++++++++++++++
+
+ For JMS-based replication this is done with:
+ <cacheEventListenerFactory
+ class="net.sf.ehcache.distribution.jms.JMSCacheReplicatorFactory"
+ properties="replicateAsynchronously=true,
+ replicatePuts=true,
+ replicateUpdates=true,
+ replicateUpdatesViaCopy=true,
+ replicateRemovals=true,
+ asynchronousReplicationIntervalMillis=1000"
+ propertySeparator=","/>
+
+ This listener supports the same properties as the RMICacheReplicationFactory.
+
+ Cluster Bootstrapping
+ +++++++++++++++++++++
+
+ Bootstrapping a cluster may use a different mechanism to replication. e.g you can mix
+ JMS replication with bootstrap via RMI - just make sure you have the cacheManagerPeerProviderFactory
+ and cacheManagerPeerListenerFactory configured.
+
+ There are two bootstrapping mechanisms: RMI and JGroups.
+
+ RMI Bootstrap
+
+ The RMIBootstrapCacheLoader bootstraps caches in clusters where RMICacheReplicators are
+ used. It is configured as per the following example:
+
+ <bootstrapCacheLoaderFactory
+ class="net.sf.ehcache.distribution.RMIBootstrapCacheLoaderFactory"
+ properties="bootstrapAsynchronously=true, maximumChunkSizeBytes=5000000"
+ propertySeparator="," />
+
+ The RMIBootstrapCacheLoaderFactory recognises the following optional properties:
+
+ * bootstrapAsynchronously=true|false - whether the bootstrap happens in the background
+ after the cache has started. If false, bootstrapping must complete before the cache is
+ made available. The default value is true.
+
+ * maximumChunkSizeBytes=<integer> - Caches can potentially be very large, larger than the
+ memory limits of the VM. This property allows the bootstraper to fetched elements in
+ chunks. The default chunk size is 5000000 (5MB).
+
+ JGroups Bootstrap
+
+ Here is an example of bootstrap configuration using JGroups boostrap:
+
+ <bootstrapCacheLoaderFactory class="net.sf.ehcache.distribution.jgroups.JGroupsBootstrapCacheLoaderFactory"
+ properties="bootstrapAsynchronously=true"/>
+
+ The configuration properties are the same as for RMI above. Note that JGroups bootstrap only supports
+ asynchronous bootstrap mode.
+
+
+ Cache Exception Handling
+
+ By default, most cache operations will propagate a runtime CacheException on failure. An
+ interceptor, using a dynamic proxy, may be configured so that a CacheExceptionHandler can
+ be configured to intercept Exceptions. Errors are not intercepted.
+
+ It is configured as per the following example:
+
+ <cacheExceptionHandlerFactory class="com.example.ExampleExceptionHandlerFactory"
+ properties="logLevel=FINE"/>
+
+ Caches with ExceptionHandling configured are not of type Cache, but are of type Ehcache only,
+ and are not available using CacheManager.getCache(), but using CacheManager.getEhcache().
+
+
+ Cache Loader
+
+ A default CacheLoader may be set which loads objects into the cache through asynchronous and
+ synchronous methods on Cache. This is different to the bootstrap cache loader, which is used
+ only in distributed caching.
+
+ It is configured as per the following example:
+
+ <cacheLoaderFactory class="com.example.ExampleCacheLoaderFactory"
+ properties="type=int,startCounter=10"/>
+
+ Cache Extension
+
+ CacheExtensions are a general purpose mechanism to allow generic extensions to a Cache.
+ CacheExtensions are tied into the Cache lifecycle.
+
+ CacheExtensions are created using the CacheExtensionFactory which has a
+ <code>createCacheCacheExtension()</code> method which takes as a parameter a
+ Cache and properties. It can thus call back into any public method on Cache, including, of
+ course, the load methods.
+
+ Extensions are added as per the following example:
+
+ <cacheExtensionFactory class="com.example.FileWatchingCacheRefresherExtensionFactory"
+ properties="refreshIntervalMillis=18000, loaderTimeout=3000,
+ flushPeriod=whatever, someOtherProperty=someValue ..."/>
+
+ Terracotta Clustering
+
+ Cache elements can also contain information about whether the cache can be clustered with Terracotta.
+ The <terracotta> sub-element has the following attributes:
+
+ * clustered=true|false - indicates whether this cache should be clustered with Terracotta. By
+ default, if the <terracotta> element is included, clustered=true.
+ * valueMode=serialization|identity - indicates whether this cache should be clustered with
+ serialized copies of the values or using Terracotta identity mode. By default, values will
+ be cached in serialization mode which is similar to other replicated Ehcache modes. The identity
+ mode is only available in certain Terracotta deployment scenarios and will maintain actual object
+ identity of the keys and values across the cluster. In this case, all users of a value retrieved from
+ the cache are using the same clustered value and must provide appropriate locking for any changes
+ made to the value (or objects referred to by the value).
+ * coherentReads=true|false - indicates whether this cache should have coherent reads with guaranteed
+ consistency across the cluster. By default, this setting is true. If you set this property to
+ false, reads are allowed to check the local value without locking, possibly seeing stale values.
+ This is a performance optimization with weaker concurrency guarantees and should generally be used
+ with caches that contain read-only data or where the application can tolerate reading stale
+ data.
+
+ Simplest example to indicate clustering:
+ <terracotta/>
+
+ To indicate the cache should not be clustered (or remove the <terracotta> element altogether):
+ <terracotta clustered="false"/>
+
+ To indicate the cache should be clustered using identity mode:
+ <terracotta clustered="true" valueMode="identity"/>
+ -->

+ created programmtically using CacheManager.add(String cacheName).
