Some Old News
One relatively unsung enhancement to Essbase in 188.8.131.52 was a change to CALCTASKDIMS behavior. Before 184.108.40.206, CALCTASKDIMS defaulted to a value of 1. From 220.127.116.11, Essbase selects a value for CALCTASKDIMS automatically unless overridden by the user with either the CALCTASKDIMS .cfg file setting or the SET CALCTASKDIMS calculation command.
So why am I blogging about this years after 18.104.22.168 came out? First, there is a good theoretical reason why the above Essbase ‘enhancement’ might have a seriously negative effect on calculation performance, which can be especially surprising when it occurs following a supposed upgrade. Second, this actually bit a coworker a few days ago, and it’s always satisfying (for me, if not my coworker) when empirical data and theory coincide.
