Service Class Key:

SERVICE CLASS pppppppp

Name of service class

‘CICS/IMS REGIONS SERVING THIS SERVICE CLASS WILL BE TREATED AS “STORAGE CRITICAL=YES.”’

Flag denoting that this service class has been assigned long-term storage protection. See the “Storage Protection” section of the “Workload Management Participants” chapter in z/OS MVS Planning: Workload Management.

‘SERVICE CLASS IS CPU CRITICAL.’

Flag denoting that this service class has been assigned long-term CPU protection. See the “CPU Protection” section of the “Workload Management Participants” chapter in z/OS MVS Planning: Workload Management.

PERIOD xx

Period number within service class

For velocity goal only:

VELOCITY GOAL: Period has a velocity goal
VEL_GOAL xxxxxxxx: Value of velocity goal

For response time goal only:

SHORT RESPONSE TIME GOAL: Period has a short response time goal
AVG_GOAL xxxxxxxx: Value of response time goal

DURATION xxxxxxxx

Duration of service class period

IMP_LVL xxxx

Importance level of service class period
