Limits the amount of extended common service area (ECSA) above the 16-megabyte line that CA OPS/MVS can acquire. Resetting this parameter to meet a need for more ECSA in CA OPS/MVS does not guarantee that CA OPS/MVS will be able to acquire the additional storage; the available ECSA storage of the operating system is still the main factor. For more information, see the description of the IEASYSxx member-ECSA parameter in the IBM documentation.
WARNING! If you set the value of the ECSALIMIT parameter too low, CA OPS/MVS may not be able to start or the module reload facility may not be able to function.
