As others have said here before, Oracle for the most part doesn't use reviews and performance evaluations for anything except putting people on PIPs, and to give people a sense that someone appreciates and measures their work. There is definitely no connection to reviews and bonuses and raises. By the time a review is done, decisions as to who is getting a raise, bonus or RSUs have already been made weeks/months before.
The pool for compensation comes down from EVPs (after SC and LE) and then for the most part, is further handled by the senior VP from the pool they get from the EVP. Every step along this chain of compensation is based on the relationship above. Managers are told what their people are getting and they have no input other than who they talk about as being their top performers or are in favor or are a "squeaky wheel". There is never enough money and perks to go around, so the money goes to the people that are clear contributors or sycophants, depending on your view point. As in IC2, there is no way you are going to get anything. You are just not valuable enough if you are an IC2. IC4 is when you might start to get something, and IC5 is where you are valued. Oracle doesn't make IC6 people unless they are able to walk on water, so realistically IC5 is the target to make if you are going that route. IC3 and below are cannon fodder at Oracle and can't realistically think any real compensation is coming your way.
