Hi, I am trying out a simple standalone app where i, put in 50 elements in the cache at a given fqn. I have enabled EvictionPolicy and set the maxNodes as 5. However none of the nodes are getting evicted. Here's the code and the config file:
package org.myapp; | | import org.jboss.cache.Fqn; | import org.jboss.cache.PropertyConfigurator; | import org.jboss.cache.TreeCache; | import org.w3c.dom.Element; | | | | public class TestEviction { | public static void main(String arg[]) | { | try { | TreeCache treeCache = new TreeCache(); | | PropertyConfigurator config = new PropertyConfigurator(); // configure tree cache. Needs to be in the classpath | config.configure(treeCache, "D:\\local-eviction-service.xml"); | treeCache.start(); | | System.out.println("Eviction policy class name: " +treeCache.getEvictionPolicyClass()); | System.out.println("Revisit time: " + treeCache.getEvictionThreadWakeupIntervalSeconds()); | | Fqn fqn = new Fqn("a/b/c"); | for(int i=0;i<50;i++) | { | | System.out.println("Put#"+ (i+1)); | treeCache.put(fqn, new Integer(i), "Put#" + i); | System.out.println("Exists fqn: " + treeCache.exists(fqn)); | System.out.println("Exists object: " + treeCache.exists(fqn,new Integer(i))); | } | | /* | * Check the contents of FQN | */ | System.out.println("Contents of FQN: " + treeCache._print(fqn)); | | /* | * Just verify whether eviction policy config was picked up | */ | Element ele = treeCache.getEvictionPolicyConfig(); | System.out.println(ele.toString()); | | System.out.println("Before EXPLICITLY Calling evict of FQN, Obj 1: " + treeCache.get(fqn,new Integer("1"))); | System.out.println("Before EXPLICITLY Calling evict of FQN, Obj 48: " + treeCache.get(fqn,new Integer("48"))); | | /* | * manually evict | */ | treeCache.evict(fqn); | | System.out.println("After EXPLICITLY Calling evict of FQN, Obj 1: " + treeCache.get(fqn,new Integer("1"))); | System.out.println("After EXPLICITLY Calling evict of FQN, Obj 48: " + treeCache.get(fqn,new Integer("48"))); | | } catch (Exception e) { | // TODO Auto-generated catch block | e.printStackTrace(); | } | | } | } Config file: <?xml version="1.0" encoding="UTF-8"?> | | <!-- ===================================================================== --> | <!-- --> | <!-- Sample TreeCache Service Configuration --> | <!-- --> | <!-- ===================================================================== --> | | <server> | | <classpath codebase="./lib" archives="jboss-cache.jar, jgroups.jar"/> | | | <!-- ==================================================================== --> | <!-- Defines TreeCache configuration --> | <!-- ==================================================================== --> | | <mbean code="org.jboss.cache.TreeCache" | name="jboss.cache:service=TreeCache"> | | <depends>jboss:service=Naming</depends> | <depends>jboss:service=TransactionManager</depends> | | <!-- | Configure the TransactionManager | --> | <!-- <attribute name="TransactionManagerLookupClass">org.jboss.cache.JBossTransactionManagerLookup</attribute> --> | | | <!-- | Node locking level : SERIALIZABLE | REPEATABLE_READ (default) | READ_COMMITTED | READ_UNCOMMITTED | NONE | --> | <attribute name="IsolationLevel">REPEATABLE_READ</attribute> | | <!-- | Valid modes are LOCAL | REPL_ASYNC | REPL_SYNC | --> | <attribute name="CacheMode">LOCAL</attribute> | | <!-- Name of cluster.
