Thanks for the response Chuck. Further reading outside of the regular OS documentation shows that without the DB2 SMP licensed program, there will be no benefit. I'm checking to see if there is any chance we are entitled and just don't know it. I'm hoping so, but I'm doubting it and will probably have to get pricing. Might see if I can get it installed and test under the 70 day grace period and see if it may be worth the asking price.

Does anyone have QQRYDEGREE set to something other than *NONE, not

jump through hoops to be able to change a sysval, I'm hoping someone
has some experience before I go through the trouble of getting
dispensation to change it and test for a week or so.
The Query Degree Of Parallel Processing (QQRYDEGREE) value can be controlled _within a job_ with any of the Change Query Attributes
(CHGQRYA) [using the DEGREE parameter], the QAQQINI feature [PARALLEL_DEGREE keyword in the current query options file (QAQQINI)], or the SET CURRENT DEGREE SQL statement. The batch routing for the EOD processing could set the IO parallelism [for lack of Symmetric MultiProcessing (SMP) capability being available].
