Author endorses Silver Bullet tuning approach

Mladen Gogala, author of the exciting book on dynamic web pages with Oracle, “Easy Oracle PHP” has published a great article about Oracle CBO internals for OLTP systems:


In his research, Gogala concludes that adjusting the Oracle optimizer parameters is the best way to optimize the CBO for its existing SQL load and that adjusting CBO statistics can be time-consuming:


“. . . fiddling with statistics requires quite a bit of knowledge and understanding and is usually not recommended. DBA will usually have a hard time convincing management that statistics should not be collected on a regular basis or that “regular basis” should mean “once or twice a year”. “


In sum, Gogala validates the “Holistic”, system-level CBO tuning approach used by most industry experts:


“Therefore, I find recommending the parameter based “silver bullet” approach most effective and the easiest to implement. “


Details on this holistic “Silver Bullet” tuning methodology are found in the book “Oracle Silver Bullets: Real World Oracle Performance Secrets” by Don Burleson.
