Certainly there are other storage allocations that can be affected by the z/OS R10 change in the way we determine the value for CVTMAXMP. For OA28261, XCF will use ECVT_Installed_CPU_HWM instead of CVTMAXMP for computing the initial amount of storage to obtain at IPL time. Jim Mulder z/OS System Test IBM Corp.
