I haven’t been keeping up with asktom lately but I noticed this one when I had a glance today and enjoyed it. Take a look at the last follow-up, dated 14th March 2006, and Tom’s answer. Very true and very appropriate to my recent work. Perhaps the questioner should take the number 1.53215 and display it on a pretty graph. That normally does the trick 😉
See, Tom always has the inside track on Oracle internals!
I liked this blog by Jon Emmons too, which discusses the Run Queue which is very useful in looking at system performance during tests. It’s a shame I couldn’t spell Jon’s name correctly on my comment 🙁
I was feeling snarky this morning…
Any number given to “management” would be a lie.
How very timely. The number 1.53215 very nearly found its way into a presentation I am currently preparing.

But it was funny 😉
“Any number given to “management” would be a lie.”
And that’s true. Sometimes managers are so busy looking for an answer, though, that the truth is just too awkward.

Don’t be too hasty taking it out, it might be *just* the number everyone’s looking for.
Now if you could fudge it to 1.57079633 then I’m sure someone could dream up a theoretical justification.
(Which reminds me, I once talked to a guy who designed BIG electromagnets for CERN, who told me that their back-of-an-envelope stuff was done in imperial units – becuase there are pi feet per metre, which nicely cancelled out a pi elsewhere in the forumla.)

Just like pi^2 is g … or so I used to use in university days

Don’t sweat it Doug! You also forgot to put in your URI in for some free publicity!
As for giving numbers to management… It’s more like a tree falling in the woods. Of course there’s always the trick of throwing a dollar sign next to it, that helps get management attention.
but do you spell his name correctly under “other blogs?”
It’s just work, work, work around here 😉
Thanks for spotting that. Fixed
