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.

You might want to pull an AWR or Statspack report and see what they show. Then 
you can run it through statspackanalyzer.com<http://statspackanalyzer.com> (you

instance.


That would be of dubious value.
