>Permanently fixed? Aren't SQA/ESQA pages fixed only when allocated? My mistake. They are fixed only when allocated. I should have said "The more CSA/ECSA/SQA/ESQA that is defined, the greater is the amount of storage that must be permanently fixed when storage is allocated from certain subpools that are commonly addressable and page-fixed." When such storage is defined, there is a small amount of storage page-fixed (as Jim Mulder points out), but the defined storage represents a potential performance problem if substantial amounts of it are allocated. >CSA/ECSA isn't page fixed at all Subpools 227 and 228 are fixed CSA/ECSA subpools. There are other CSA subpools that are pageable. See z/OS V1R6.0 MVS Auth Assembler Services Guide.
