Oracle Solid State Disk Tuning: High Performance Oracle Tuning with RAM Disk
暫譯: Oracle 固態硬碟調校：使用 RAM 磁碟進行高效能 Oracle 調校

Description

Written by the world's most widely-read Oracle script developers and authors of over 50 best-selling Oracle books, Mike Ault and Don Burleson share their personal experience with using Solid-State RAM disk to hypercharge Oracle performance.

As SGA data buffers are replaced by high-speed Sold-state disks the rules for Oracle tuning change radically and this indispensable books show you how to leverage RAM-SAN technology to create Oracle databases with blistering speed. You will learn proven techniques for leveraging RAM disk in an Oracle environment including changes to initialization parameters and the selective use of SSD in large database environments including UNDO, REDO and TEMP tablespaces on solid-state disk.
