Roland added it to ShowMVS 715, but it must need some work (see below). :-) Especially after the changes introduced by APAR OA18452 (z/OS 1.7 and z/OS 1.8) On a z/OS 1.8 sandbox system with RMPTTOM=10000, ShowMVS displayed "RMPTTOM = 14560 in seconds" ON a z/OS 1.6 sandbox system with RMPTTOM=10000, ShowMVS displayed "RMPTTOM = 14 in seconds". I changed it to RMPTTOM=8000 and ShowMVS displayed "RMPTTOM = 11 in seconds". Both LPARs are on a z9EC. On a production z900 LPAR running 1.8 with the default (now 3000), ShowMVS displayed "RMPTTOM = 11136 in seconds". On a production z900 LPAR running 1.6 with the default (1000), ShowMVS displayed "RMPTTOM = 4 in seconds". On a production z9EC LPAR running 1.6 with non-default of 2000, ShowMVS displayed "RMPTTOM = 3 in seconds". > > We are z/OS V1R4, soon z/OS V1R7, on a z800; just set RMPTTOM from >default 1000 to 5000â¦not really seeing any impact...any value >suggestions? > Leave it default - especially if you aren't 100% and haven't seen a drop in captured time. One less thing to change later. There was a flash on this plus lots of talk on the MXG list (from what I heard, I don't follow MXG-L). I read the flash but I don't remember exactly what it said. I think it said to do what I have set up now. 2000 for z990 or z9EC, (or z890 z9BC without throttled engines) but the PTFs for APAR OA18452 change it to 3000 for LPARs that have a uni-processor speed of more than 100 of those meaningless indicator of speed thingies. So as I am rolling out z/OS 1.8, I am removing RMPTTOM=2000 from the LPARs that have it.
