Of course, we wouldn’t link to Oracle’s readily-available price lists if there weren’t more to the story, e.g., this FAQ page on the more realistic fees associated with Enterprise Edition and its extra-cost options. Oracle’s pricing is primarily designed to lock customers into paying annual support for decades, per our page on repricing.
The vast majority of Oracle software is deployed as perpetual licensing with annual support. We often remind customers that perpetual means forever; thus, we are often reviewing contractual terms from the 1990s. Whatever price list you purchased from may no longer be available. Stated differently, whatever products and metrics you originally acquired, and are living with today, may not be relevant to your business. Conversely, the terms Oracle originally offered may be replaced with a more profitable model to Oracle, e.g., the long-dead, impossible-to-audit, Concurrency metric that should be preserved in your environment.
Oracle’s solution is to either restrict usage of a new product to its predecessor’s original scope or migrate the licensing (acquired from an old price list) to the new price list’s expanded product features. License migrations roll the annual support you’ve been paying for years, perhaps decades, into the next contract rather than drop or optimize it.
Remend’s Reduce Support Costs offering takes both old (unpublished, but archived) and new price lists into account.
