Pete Finnigan's Oracle Security Weblog

There has been a flurry of blog posts from Radoslav, http://oracledoug.blogspot.com/2005/08/jonathan-debunks-another-don-article.html - (broken link) Doug, Jonathan Lewis and from http://tkyte.blogspot.com/2005/08/getting-credible-information.html - (broken link) Tom Kyte all about a paper written by Don titled "Undocumented secrets for super-sizing your PGA" that was recently released.

I like undocumented and hard to find information so I am always interested by papers like this. I won't get into the for and against of this particular article and the opposers, Radoslav has done a good job of summarising the current state of this farce in his post "The Don Burleson's article"

I wanted to highlight this post not for many of the reasons that others have quoted but for one reason in particular. This is that whilst undocumented information is interesting to know it should not be used in production databases under any circumstances, also hidden parameters should never be set unless Oracle support direct you to do so.
