6.7 Memory Measurements

Real memory is one of the most constrained and expensive
resources in the I/S facility.  The effective management of
memory requires understanding of how this expensive resource
is being used.

The CA MICS Batch and Operations Analyzer provides many
memory measurement data elements in the Batch Information
Area files.  This section explains what measurements quantify
use of the memory and what they represent.

    1 - Real and Virtual Memory
    2 - Address Spaces and the Memory Map
    3 - Paging and Swapping
    4 - Page Seconds and Memory Service Units
