PDSE1: Allows you to select the restartable SMSPDSE1 address space.
COMMONPOOLS(NEW): SMSPDSE1 abandons the old common storage cell pools and creates a new set of cell pools in ECSA.
COMMONPOOLS(REUSE): This is the default. SMSPDSE1 reuses the existing common storage cell pools that were created by the previous instance of SMSPDSE1.
Restriction: When you restart SMSPDSE1, the old storage cell pools are not deleted. Reuse the existing ECSA cell pools to avoid ECSA depletion. If you restart SMSPDSE1 because of a problem with the existing ECSA cell pools, create new cell pools by specifying COMMONPOOLS(NEW).
