Assuming that you are using the Standard Edition/2 of the database, this is licensed at $17,500/core. On x86, there is a 2-for-1 core discount.

If you download Enterprise Edition and use it to perform an upgrade from your SE2 database, then you will then be on the hook for the full $47,500/core.

There are two ways to undo this license change. a) Run "catdwgrd.sql" to get back to the SE2 release, then upgrade again with the correct license, or b) unload all of the data in the database (via exp/imp or data pump), then load it into a new database that is created with the correct license.

Staying on an EE database will certainly place you on the new pricing tier.
