Storage Target

To manage central storage, SRM defines a storage target of protective central. This specifies the number of frames that are protected in central storage. The system will not 'steal' below this value.

The storage target assigned depends on the service class period goal.

For short response time goals, the service class period gets a protective processor storage target. Every address space in the service class period has the same target.

For long response time, velocity, or discretionary goals, or for server internal service classes ($SRMSnnn), SRM may define individual storage targets for the address spaces in the service class period. Each address spaces may have one or more of each type of storage targets. Storage targets for individual address spaces are recorded in subtype 5, in the monitored address space information section.
