Specifying when automatic primary space management can process

The PRIMARYSPMGMTCYCLE parameter of the DEFINE command defines the cycle of automatic primary space management.

Example: To define an automatic primary space management cycle, use the following command:
DEFINE PRIMARYSPMGMTCYCLE(YNNNYNN) -
CYCLESTARTDATE(1998/09/12)  
Note: Although this example shows automatic primary space management running two days a week (Saturday and Wednesday). You might want to run it more often.
