Before you begin: ACTIVATE is a command of last resort. It should only be used when the restart failed to work and the operator forced the SMSPDSE1 address space down manually. Note: IBM® does not recommend forcing down the SMSPDSE1 address space because the results are unpredictable. If the SMSPDSE1 address space is stopped, you can use the VARY SMS,PDSE1,ACTIVATE command to activate the SMSPDSE1 address space.
Perform the following steps to activate the SMSPDSE1 address space after it has been shut down:
VARY SMS,PDSE1,ACTIVATE,COMMONPOOLS(REUSE)
In this example, the SMSPDSE1 address space is activated and the common storage cell pools in ECSA are reused. SMSPDSE1 startup processing creates storage cell pools in the ECSA. When SMSPDSE1 restarts, the old storage cell pools are not deleted. Normally, it is preferable to reuse the existing ECSA cell pools to avoid ECSA depletion. If the SMSPDSE1 restart is related to a problem with the existing ECSA cell pools, then you can create new ones by specifying COMMONPOOLS(NEW).
VARY SMS,PDSE1,ACTIVATE,COMMONPOOLS(NEW)
In this example, the SMSPDSE1 address space is activated and new storage cell pools are created in the ECSA.
