RE: Data Dictionary Hit Ratio - myth or fact?

I predict that statspackanalyzer.com will tell you that your database will benefit from solid state disks.

(Can anyone come up with a genuine (not faked) StatsPack report that DOESN'T recommend the purchase of SSDs?)

You are assuming that Lewis is 100% accurate in everything he says and statspack analyzer isnt? Not necessarily a good assumption... At the very least, that article is over a year old, and according to the statspack analyzer site, its analysis is continually revised. I have never seen the particular phrasing he quotes, so I suspect it is no longer used in any case.

Statspack analyzer is currently very good at identifying the number of soft v. hard parses, which is very important to know. I have used it several times, and found it accurate. On Wed, Mar 19, 2008 at 11:02 AM, Jared Still <jkstill_at_gmail.com<mailto:jkstill_at_gmail.com>> wrote:

That would be of dubious value.
