Hi, i´m having some problems with cache eviction. I have used the TreeCache implementation
with the following configuration:
| <?xml version="1.0" encoding="UTF-8"?>
|
| <server>
|
| <classpath codebase="./lib" archives="jboss-cache.jar,
jgroups.jar"/>
|
| <mbean code="org.jboss.cache.TreeCache"
name="jboss.cache:service=TreeCache">
|
| <depends>jboss:service=Naming</depends>
| <depends>jboss:service=TransactionManager</depends>
|
| <attribute
name="IsolationLevel">REPEATABLE_READ</attribute>
| <attribute name="CacheMode">LOCAL</attribute>
|
| <!-- Name of the eviction policy class. -->
| <attribute
name="EvictionPolicyClass">org.jboss.cache.eviction.LRUPolicy</attribute>
| <!-- Specific eviction policy configurations. This is LRU -->
| <attribute name="EvictionPolicyConfig">
| <config>
| <attribute
name="wakeUpIntervalSeconds">5</attribute>
| <!-- Cache wide default -->
| <region name="/_default_">
| <attribute name="maxNodes">1000</attribute>
| <attribute
name="timeToLiveSeconds">10</attribute>
| </region>
| <region name="/teste">
| <attribute name="maxNodes">1000</attribute>
| <attribute
name="timeToLiveSeconds">10</attribute>
| </region>
| </config>
| </attribute>
| </mbean>
| </server>
|
I was expecting that with this config nodes with live greater than 10 seconds be collected
by LRU policy and the be throwed away since there is not CacheLoader assigned.
But the node remains in cache after the assigned time.
the code used for testing:
| cache.put(new Fqn(new Object[] { "/test", 1 }), "item",
"1");
| Thread.currentThread().sleep(30000);
| System.out.println(cache.get(new Fqn(new Object[] { "/test", 1}),
"item"));
|
Since the node was not removed i try removing it in code, as:
cache.put(new Fqn(new Object[] { "/test", 1 }), "item",
"1");
| cache.remove(new Fqn(new Object[] { "/teste", 1 }));
| Thread.currentThread().sleep(30000);
| System.out.println(cache.get(new Fqn(new Object[] { "/test", 1}),
"item"));
And again the node remains in cache.
Any suggestions ???
Thanks.
