When to use sysplex data sharing

The two primary reasons for moving to a sysplex data-sharing environment involve cost and availability. With z/OS® sysplex data sharing, you can take advantage of the lower cost of the CMOS-based hardware, spreading the workload to multiple CPUs while maintaining one logical view of your databases; this can be done without making any application software changes.

Availability in this environment is improved, because if one CPU in a sysplex is lost, the workload can be moved to the remaining CPUs.
