Disable the schemaExport on the hibernate [message #114554]

I'm trying to disable the schema export each time I connect to the
database. It takes a long time to connect and if it is a different
schema it tries to update and that is the wrong solution for production
application.

Here is what I tried:
I create properties for hibernate and assign -
props.setProperty(Environment.HBM2DDL_AUTO, "validate");
dataStore.setHibernateProperties(props);

Please note that I need to use the properties because my application
dynamically changes the database connection with the user input. So I
do not have a configuration file and I manage it via properties.

This should not export the schema but only validate it. However, it
does not have any impact on hibernate. Hibernate always rebuild the schema.

Any ideas how to cause Hibernate not to export the schema.
Tunning it OFF is the best option I'm looking for. Validate is my second.

Thanks
Yigal

Hi Yigal,
There is also a specific Teneo option: PersistenceOptions.UPDATE_SCHEMA, this should be set to
false. This property should be passed to the setPersistenceProperties method.
I can see that the teneo option is confusing/contradicting related to the same kind of option in
Hibernate. Can you enter a bugzilla for this? Then I can think of a way to make this more intuitive
or at least also listen to the hibernate property.

Hi Martin,
The TENEO option worked well.
Yes it is confusing that the TENEO overrides the hibernate.
I'll enter a request to clarify it.
