I literally had 95% 5's on all my performance reviews and didn't see raises.
That's because performance reviews were for show and didn't correlate to anything meaningful. Stack ranking was held behind closed doors and wasn't mentioned to employees -- that's where the real decisions were made that could impact comp and even then the percentages of individual contributors getting a raise or stock was incredibly small.
Ever since the database market share started to be impacted by SQL server and open source alternatives, Oracle's strategy has been to do whatever is needed to "manage" (i.e. cut) costs. No raises, reducing benefits, shifting work to India, layoffs and pushing out tenured employees while hiring cheaper college grads have all been part of the game. The layoffs have become a regular thing at Oracle, but they manage those
too in order to stay out of the press.
