Title: Oracle Database Memory Structure Control: How it works (latches & mutexes)


Memory structure control is core to all Oracle Database operations and one of the most fascinating Oracle Database internals and performance topics! Memory structure activity must be strictly controlled or the database gets corrupted. This presentation will explore how latches and mutexes are implemented, their algorithms, where diagnostic data comes from, and how the Oracle Database continues to improve serialization control in newer releases. The cache buffer chains and the library cache are used as examples throughout the presentation. This is a very practical yet deep internals presentation, filled with amazing discoveries about how the Oracle Database works.
