Tuning Oracle with RAM

Most Oracle professionals recognize the huge benefits of RAM data caching, a techniques that can improve data access speeds by up to 300x when compared to platter-based disk. RAM can also support blistering table insert speeds of over a half million rows per second. 

For complete details, see my master book "Oracle Tuning: The Definitive Reference":


The web site www.statspackanalyzer.com is a great way to see if your Oracle database is I/O-bound and you can simply paste-in a STATSPACK or AWR report and see a detailed I/O analysis.


Oracle's Time Ten tool is the latest data caching approach in Oracle, but there are several major approaches to RAM data caching today:

Solid State Disk data caching - RAM-SAN can hypercharge an I/O-bound Oracle database overnight, speeding-up I/O operations. See the book "Oracle Solid State Disk Tuning: High Performance Oracle Tuning with RAM disk" for benchmarks and tips on using SSD.

Large RAM Buffer Data Caching - Many Oracle professionals choose to use a very large db_cache_size, and most of the recent world-record TPC benchmarks use Oracle data buffers in excess of 50 gigabytes, and one Oracle benchmark that used over a terabyte of RAM. For details, see the book "Database Benchmarking: Practical methods for Oracle":
