Hi Andres.
when you build a PersistenceManager, the instance must be done just once
during the call in your method, class, etc., so, if you want to continue
with doing more tasks with it, it's ok. just when the call to your manager
class is ended then you can delete or end the manager, otherwise you can
keep using it. Remember the process of building the manager is done just
once in your whole app, but the instances can be many.
Rgds.
