Mike This is because the data for the “DA” panel (derived from calls to both RMF and JES) from 2.4 onwards is collected centrally by the SDSFAUX address space rather than being gathered by every SDSF user every time they press enter on the panel.
I think there is a good case to update the SDSF manuals to reflect more realistic tuning advice. Rob Scott Rocket Software From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Mike Shorkend Sent: 16 March 2022 12:29 To: [email protected] Subject: SDSFAUX Priority EXTERNAL EMAIL Hi, On z/OS 2.4, I have set up SDSFAUX so that it goes to a medium priority service class as recommended by the documentation. When an LPAR is very busy, hitting enter on the SDSF DA screen does not change the cpu% column values. I looked at SDSFAUX and it was starved for CPU. I changed SDSFAUX to a higher service class and the problem went away. I do not recall this happening in previous z/OS versions. I will just leave SDSFAUX at a higher priority but was curious if anyone else ran into this.
