When creating more as 300 Object in Oracle with insert="false" and generated="insert" by property - Tag in Mapping-File
causes an ORA-01000 "too many open cursors"...

It is executed using the following Java code:

SessionFactory sessionFactory;
    
     try {
            // Create the SessionFactory from hibernate.cfg.xml
            sessionFactory = new Configuration().
             configure().
             buildSessionFactory();
        } catch (Throwable ex) {
            // Make sure you log the exception, as it might be swallowed
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    
        try{
    
         for (int i = 0; i <= 301; i++) {
        
         Session session = sessionFactory.getCurrentSession();
         Transaction tx = session.beginTransaction();

Test test = new Test();
session.save(test);

tx.commit();

         }
    
} catch (Exception e) {
System.out.println(e.getMessage()+e.getClass().toString());
}
