10 MB total data. How often will it be accessed? How often will it be updated? What is the required response time for a read-only access and for an update access? Must the data survive an unscheduled system outage?
This could be implemented as a DIV application, a 14 cylinder DASD data set, a chunk of ECSA, a common data space, or a common memory object above the bar. Lots of places to store this data with different access speeds and different difficulty levels for maintaining the software that does it. If it were stored on DASD, e.g., you could read the entire 10 MB into storage in about 1/5 of a second, move some of it to the requestor's buffer, then delete it. Or read it in once and let the paging supervisor do it even faster.
