Keep in mind the difference in price between SE and EE is entirely dependent upon your ability to negotiate with your Oracle sales rep. Oracle has list prices (http://store.oracle.com) but those are merely the beginning point for negotiations.
Depending on the volume of log files being shipped best practice is
to do the shipping on a separate NIC card using a private network.
You can find configuration files here:
