How Oracle RAC Cache Fusion Works
Learn the mysteries of how Oracle RAC Cache Fusion works. Cache Fusion is the secret to making Oracle RAC a scalable database platform. You will learn how cache fusion works, the differences between global cache current and consistent read transfers, the differences between two-way and three-way transfers and the associated wait events.
Oracle Ace and author Brian Peasland provides an in-depth demonstration of global cache transfers in action by utilizing Oracle Trace and session statistics (v$sesstat and v$statname).
