Address Space Paging Plots

SRM uses address space paging plots when assessing whether to increase or decrease the central storage or processor storage allocated to an address space. There are two address space paging plots:

Central Storage Plot

SRM uses the central storage paging plot when assessing increasing or decreasing the central storage allocated to an address space.

Central Storage Plot

x axis
Address space size in frames.
y axis
Each one of the following:
  • Page-in rate per captured (task and SRB) second from auxiliary and expanded storage.
  • Paging cost in milliseconds per elapsed second from auxiliary and expanded storage.
  • Captured time in milliseconds per elapsed second.

Processor Storage Plot

SRM uses the processor storage paging plot when assessing increasing or decreasing the processor storage allocated to an address space.

Processor Storage Plot

x axis
The address space size in frames.
y axis
Each one of the following:
  • Page-in rate per captured (task+SRB) second from auxiliary storage.
  • Paging cost in milliseconds per elapsed second from auxiliary storage.
  • Captured time in milliseconds per elapsed second.

The address space paging plots are recorded in subtype 5 records.
