Persisting ecore model in DB takes too long time!!! [message #912911] Fri, 14 September 2012 11:41

Hi I am using TENEO which in turn uses Hibernate.

TENEO is having an ecore model and it will be loaded with a file of size 60MB.

The ecore will be persisted in database using Hibernate by TENEO. But this process is taking too long time.

My Properties settings are as below

props.setProperty(Environment.DIALECT, org.hibernate.dialect.Oracle10gDialect.class.getName());
props.setProperty("hibernate.cache.region.factory_class", "org.hibernate.cache.ehcache.EhCacheRegionFactory");
props.setProperty(Environment.HBM2DDL_AUTO, "create");
props.setProperty("hibernate.jdbc.batch_size", "30");

And the code that writes data to DB is below

final SessionFactory sessionFactory = hbds.getSessionFactory();
// Open a new Session and start transaction.
final Session session = sessionFactory.openSession();
session.beginTransaction();; // Taking too long time

// Commit the changes to the database.

How to solve this problem?

My ecore is having 25 EClass. Loading the 60Mb file to model takes 6 seconds but insertion of data takes 1 hour!!!

Is it the problem with the way ecore model is made or is it problem of hibernate?
