Hi folks - Just wondering if beginning a new transaction in Hibernate actually allocates a connection to the DB?

I'm concerned b/c our server begins a new transaction for each request received, even if that request doesn't interact with the DB. We're seeing DB connections as a major bottleneck, so I'm wondering if I should take the time narrow the scope of my transactions.

Searched everywhere and haven't been able to find a good answer. The very simple code is here:

    SessionFactory sessionFactory = (SessionFactory) Context.getContext().getBean("sessionFactory");
    sessionFactory.getCurrentSession().beginTransaction();
    sessionFactory.getCurrentSession().setFlushMode(FlushMode.AUTO);

thanks very much! a
