Agreed, and further to that point... ... Does the WLM Policy include Using / Delay for I/O samples?
In my extensive experience if so 1) The Velocity achieved is normally very high. (Indicates a protective goal of 70% or higher, generally. Imp 1 BTW.) 2) The samples are dominated by Using I/O. So probably the CPU component - hence DP - is "almost random". (Don't shoot me for the rhetorical and inaccurate flourish.) :-) Some people might benefit from / enjoy / snigger at / curse at THIS: https://www.youtube.com/watch?v=UMtjB_GUyxs . It's a relevant YouTube screencast of mine "Screencast 12 - Get WLM Set Up Right For DB2".
