OpenJPA and ehcache configuration

[Georgi Naplatanov]

Hi all.

I want to configure ehcache 2.2.0, OpenJPA plugin for ehcache 0.2 and 
OpenJPA 2.1-snapshot.

Below are my configuration files, but I am not sure that it's right 
configuration.

persistence.xml

<property name="openjpa.QueryCompilationCache" value="true"/>
<property name="openjpa.jdbc.QuerySQLCache" value="true"/>
<property name="openjpa.QueryCache" value="ehcache"/>
<property name="openjpa.DataCacheManager" value="ehcache"/>


ehcache.xml

<?xml version="1.0" encoding="UTF-8"?>
<ehcache>
        <defaultCache
              maxElementsInMemory="1000"
              eternal="false"
              timeToIdleSeconds="300"
              timeToLiveSeconds="600"
              overflowToDisk="false"
              memoryStoreEvictionPolicy="LRU"
              />

        <!-- OpenJPA data cache -->
        <cache name="openjpa"
                     maxElementsInMemory="5000"
                     eternal="false"
                     timeToIdleSeconds="300"
                     timeToLiveSeconds="600"
                     overflowToDisk="false"
                     memoryStoreEvictionPolicy="LRU"
              />
        
        <!-- OpenJPA query cache -->
        <cache name="openjpa-querycache"
               maxElementsInMemory="1000"
               eternal="false"
               timeToIdleSeconds="300"
               timeToLiveSeconds="600"
               overflowToDisk="false"
               memoryStoreEvictionPolicy="LRU"
              />
        
</ehcache>

Is this configuration correct ?

Should I configure :
        - "openjpa.DataCache" and "openjpa.RemoteCommitProvider" in 
persistence.xml
        - additional cache names in ehcache.xml

Best regards
Georgi
