•(β) stands for the total number of resources available in the subsystem
(β) = 26,17 6 or 57,600 or 104,7 68 or 146,688 or 209,600
For details, see Table 10 on page 24.
Establishing relationships by dataset copying
To establish relationships between extents, the number of require d resources is the same as the
number of resources used per relationship, provided that no extents in the same volume overlap.
If the
extents used for establishing the relationships overlap, the number of resources required
to establish the relationships is the number of resources to be used multiplied by the number of
extents that overlap.
The following gures illustrate the different cases of dataset copying, for example, whether the
extents overlap or not. For information about the calculation example of the used resources,
see Table 29 on page 60.
