Hello, I have this error : java.lang.OutOfMemoryError: Java heap space So I used a profiler to see what was wrong. I have very lots of object of that classes : org.apache.derby.impl.store.raw.data.StoreRecordHeader org.apache.derby.impl.store.raw.data.RecordId (I can't find those classes into derby javadoc :c( )

Yes, record headers are objects created when a page is brought into the cache. The maxHeap to pageCache ratio I talked about in my previous message accounts for these and the many other objects created to support the activities of the Derby database engine.
Please see the information in my response to your previous post (Iterate over big table...) and if you are still having problems after increasing the ratio of the JVM-maximum-Heap to Derby-pageCache please post the ratio you are using and the settings for maxHeap and pageCache.
