If your below the line private area decreased it I will step out on a
limb and say no one is monitoring and managing it. We have been able to
grow PVT from a standard 9M to 10M and EPVT as well in the last few
years. IBM is doing good work in the area of Virtual Storage Constraint
Relief (VSCR).
Same here. Our <16MB private user area has grown over the years.
IPCS shows the following for one of our z/OS 1.9 system's below-the-line
virtual storage mapping. It has x'B00000' or 11MB of private user area.
We're running CICS and DB2. No IMS.
