I've been invited to speak again at the Hotsos Oracle Symposium, March 2-6 in Dallas, Texas. I'm more than happy to do this because I found last year's symposium to be a first class operation with plenty of great speakers and an attentive audience who were very interested in performance analysis and capacity planning in general, in addition to it's applicability for ORACLE.
Just as an aside, if you look at the Hotsos company logo at the top of their web pages, you'll see some equations or bits of equations. The first of these is the denominator of the famous Erlang-C function (A. Erlang, 1917). More on that in an upcoming blog entry.
