John - If you have not installed the PTF that provides the function, I don't know how it could be working. Are you running z/OS 1.10...? I'm guessing that the function is built into the base code at that level since there's no PTF for 1.10.
But if you are asking how you can see the ARC* address spaces by using an MVS command and not in SDSF... that's different. We are a JES3 shop and we use EJES, so YMMV, but since these address spaces are created dynamcically (ASCRE, I think), they will only appear in the ACtivity (DA) panel as ARC*. In the EJES STatus panel (not sure of the equivalent SDSF command), they will appear as IEESYSAS with a STEP name of ARC*. We have been running with that function active for quite a while now and it does work, as long as with ALL maintenance applied as well as some APAR code (!), but it does still have problems, including a serious storage leak that is currently under investigation.
