[Teneo] Diasbling Two Phase Load Hibernate [message #957371]

Hi all,

I have a class/entity 'Department'.

It don't have any references to any other class or entities.

When I fetch it using Teneo like below

 Query query = session.createQuery( "from Department" );
 List<EObject> listObj= query.list();

It's taking time in resolving associations as I am seeing below in log

DEBUG org.hibernate.engine.TwoPhaseLoad - resolving associations for [Department#Dept-1]

Why is this happening even though I don't have associations.

Is there anyway I can tell teneo/hibernate to avoid this so that I get quicker turnaround time.

Thanks,
Appasamy

Hi Appasa,
Afaics Hibernate still sees an association, probably from Employee to Department. Does your ecore really not show an
association? If you changed your model, have you regenerated the java code (the model is part of the code, that's used
by Teneo).

I am not sure that resolving association actually means that the referenced object is loaded. To really know/see what
happens you have to check the sql used by hibernate. You can see the sql by setting the hibernate hibernate.show_sql to
true (in the properties you pass to the hibernate store).

Also read the hibernate manual for things like fetch and join strategies. It is quite possible to tune the load
strategies of hibernate.

gr. Martin

Hi Martin,

Thanks for the input.

Oops!. The actual query is

Query query = session.createQuery( "from Department" );

Not "from Employee"

Employee- Associated to Department
Department - Not associated to any entity

So my doubt of why hibernate trying to resolve association when I try to load just all Departments.

I will also look in to hibernate documentation as you suggest.

Thanks Martin.
