WLM was introduced in the early 1990s and most sites most sites implemented goal mode in the late 90s or early 2000s. A lot has changed since then. New WLM features have been introduced. Options and features are enabled (or not) either when defining a new policy or when a new feature becomes available but then never reviewed for applicability in the face of significant changes in the hardware and software environment.
Just like regularly reviewing your goals, revisiting your WLM options periodically is a good thing as well. Join Scott Chapman in this session has he reviews various WLM options and shows how one long-standing recommendation is now perhaps skewing results in a counter-productive fashion.-Scott Chapman-Enterprise Performance Strategies Inc.
