What z/OS levels? What levels of DB2 on all those LPARS? >It is claimed a runaway DB2 DIST asid on the DVLP LPAR is burning CPU and >stealing MIPS from the PROD LPAR and affecting production. Based on what were those claims made? I would like to see for example, RMF or SMF data/reports or some other tools used to prove that claims.

I'll leave that to the real performance gurus on IBM-MAIN.
