    Problem when using EJB3EntityTreeCache for caching entities

    Mihai Ratiu Newbie

      Hi,

      I'm new to Jboss Cache and I'm trying to use Jboss Cache 1.4.0SP11 "Cayenne" to cache some of my entities.

      I'm using for my application jboss-4.0.5-GA version of the server, in configuration all. The application is using ejb3 entities and I need to reduce the amounts of DB calls to some tables by using the jboss level 2 cache.

      I already install EJB3 RC9 Patch 1 for my server configuration, and configured the ejb3-entity-cache-service.xml as following:


      <?xml version="1.0" encoding="UTF-8"?>


      <!-- ==================================================================== -->
      <!-- Defines TreeCache configuration -->
      <!-- ==================================================================== -->

      <!-- uncomment next three statements if using JGroups multiplexer,

      5 -->

      The entities needed to cache were annotated this way:

      @Entity(name = "DataStoresConnEntity")
      @Table(name = "DATASTORES", uniqueConstraints = {})
      @Cache(usage = CacheConcurrencyStrategy.TRANSACTIONAL)
      @NamedQueries(...)
      public class DataStoresConnEntity implements Serializable
      {
      ....
      @OneToMany(mappedBy = "dataStoresEntity", fetch = FetchType.LAZY)
      @Cache(usage = CacheConcurrencyStrategy.TRANSACTIONAL)
      public Collection getPendingDataStoresEntities()
      {
      return pendingDataStoresEntities;
      }
      ....
      }


      and

      @Entity(name = "PendingDataStoresConnEntity")
      @Table(name = "PENDINGDATASTORES")
      @Cache(usage = CacheConcurrencyStrategy.TRANSACTIONAL)
      @NamedQueries(...)
      public class PendingDataStoresConnEntity implements Serializable
      {
      ...

      @ManyToOne(targetEntity = DataStoresConnEntity.class)
      @JoinColumn(name = "DATASTOREID", referencedColumnName = "DATASTOREID")
      public DataStoresConnEntity getDataStoresEntity()
      {
      return dataStoresEntity;
      }

      ...

      }


      We decided that the named queries doesn't need to be cached only the ejb3 entities.

      The problem is that after some processing, when the processing stops, the entities are evicted from the cache very fast , after few seconds(~10s). I tried also to set up wakeUpIntervalSeconds to a large number and also tried a setup for "maxAgeSeconds" to 0.

      Even if I remove the evictionPolicy the behavior is still the same.

      Does anybody have an idea why this strange behavior is happening?


      Since the new year is coming soon I wish you a Happy New Year!

              This is an updated version of ejb3-entity-cache-service.xml that I tried to use and also did not worked. My cache is cleared really fast.

              Is there any configuration that I'm missing under this configuration file? I'm suspecting that I'm missing an configuration to entities, something like @Cache annotation given to the two entities depicted above.

              Thanks in advance,
              Mihai

                As an update I ran the clustered entity example provided in ejb3 RC9 Patch under the same jboss configuration and it works fine, the information is not removed from the treecache nodes.

                The only difference from my seems to be that after calling persist or merge methods I also call flush for this tables.
                Can this affect the eviction of the cache? I wasn't able to find any reference to this in all the documentation that I have been reading.

                Does anybody have an idea of this behaviour?

                  Please give an example of how you are calling "flush for tables".

                    After some further investigations, after reading the server logs, i saw that the cache nodes are removed(not evicted after specified time), by calling _remove method, short time after the entities are stored into the cache.

                    I will send you some logs some server logs containing removal process:

                    I'm not sure if I understand about what configuration you are talking about when saying "flush on tables". I also can send you the hibernate configurations from my persistence.xml file.

                    <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"></property>
                    <property name="hibernate.connection.release_mode" value="on_close"></property>
                    <property name="hibernate.transaction.auto_close_session" value="true"></property>
                    <property name="hibernate.show_sql" value="false"></property>
                    <property name="hibernate.cache.provider_class" value="org.jboss.ejb3.entity.TreeCacheProviderHook"/>
                    <property name="hibernate.treecache.mbean.object_name" value="jboss.cache:service=EJB3EntityTreeCache"/>

                      My "flush for tables" bit came from this:

                      The only difference from my seems to be that after calling persist or merge methods I also call flush for this tables.


                      Please give me a code example of this. Most likely it's what is triggering the JBC remove call. I don't want to poke around guessing when you have code. :)

                        flush for tables was calling entity manager's flush method. Should this be the problem?

                        I don't think that any code is necessary hence I only annotate the two entities with @Cache and added the two new hibernate props to the persistence.xml.

                        Can this flush() call produce the removal of the cache nodes?

                          I had a chance to poke around a bit. In the Hibernate code the only path I see that results in the entire region for an entity being removed from the cache is via the BulkOperationCleanupAction, which gets clears the cache region during tx commit if the tx executed some "bulk operation". Typically that would be the execution of native SQL whereby Hibernate couldn't track when entity instances were affected by the the SQL, forcing the invalidation of everything all instances of the entity.

                          Is your code doing that?

                            Hi people,

                            I have exactly the same problem as mihai.ratiu does. As I understand, when I execute native query in my code, the cache gets completely clear?? This is the answer I expected, when I try to remove all native queries and replace it by ejb3 queries, the cache remains full.

                            Does it mean I can't use any native sql queries in my code to keep the cache working normally?? Heh, that's pretty not good as native queries are much more faster and for some operations I just can't use normal queries...

                            Another question is here: How can I replace native queries?

                                Thank you for your reply. That's true I'm using native queries too. After some tests I was able to keep la my cache data into nodes.

                                Glad that I wasn't the only one that meet that issue and get a solution.
