Eviction Policy Config not working

[lords_diakonos]

Using the following xml config I have objects in the FQN "ContentletCache" greater then 2. I am trying to get it to respect the maxNodes.

<attribute name="EvictionPolicyConfig">
 <config>
 <attribute name="wakeUpIntervalSeconds">3</attribute>
 <!-- This defaults to 200000 if not specified -->
 <attribute name="eventQueueSize">500000</attribute>
 <!-- Name of the DEFAULT eviction policy class. -->
 <attribute name="policyClass">org.jboss.cache.eviction.LRUPolicy</attribute>
 <!-- Cache wide default -->
 <region name="/_default_">
 <attribute name="maxNodes">10000</attribute>
 <attribute name="timeToLiveSeconds">864000</attribute>
 </region>

 <!-- contentlet cache -->
 <region name="/ContentletCache">
 <attribute name="maxNodes">2</attribute>
 <attribute name="minTimeToLiveSeconds">0</attribute>
 <attribute name="timeToLiveSeconds">0</attribute>
 <attribute name="maxAgeSeconds">0</attribute>
 </region>
 </config>
 </attribute>

My java logic is is as following

public DotJBCacheAdministratorImpl() {
 CacheFactory<String, Object> factory = new DefaultCacheFactory<String, Object>();
 cache = factory.createCache("cache-configuration.xml");
 //cache.getRegion(Fqn.fromString(CacheLocator.getContentletCache().getPrimaryGroup()), true);
 }

cache.put("ContentletCache",key,object);

return cache.get("return cache.get(group, key);", key);

For what it is worth now I changed the _default_ region to maxNodes = 1 and it still caches more.

I do have the 1

so it should be firing i think

Anybody know what is happening?

In your logs - do you see the eviction thread kicking in and attempting to evict stuff every 3 seconds?

[lords_diakonos]

Well it was firing. I think the issue though I am testing now is that I thought the objects within the FQN were nodes. They don't seem to be though. So I had a FQN which I put a bunch of objects inside. It is all one node though. I was confused here.

My question would now be what is the best way to handle this? Do I need a separate node for every object? That seems kind of dumb as all my nodes and keys would be the same.

[manik]

A lot of people do use a separate node for each object - and hence JBCACHE-1082.

Another approach is logical groupings. E.g., if you store information about a person, you could store name, age and postcode on the same node.
