The marketing guys at Oracle must like the term “smart.” They have applied it to a dozen or so different features on the Exadata platform. They also seem to like the term “flash,” which is associated with at least a half dozen features as well. To add to the confusion, there are two features in Oracle Database 11g Release 2 that have almost exactly the same names, Database Smart Flash Cache (DBFC) and Exadata Smart Flash Cache (ESFC). While both features make use of flash-based memory devices, they are very different. This chapter is focused on ESFC so we’ll only mention DBFC in passing.
