Allocation by
Logical
Records
Allocation by logical records (ALR) automatically calculates the primary
extent size. ALR overrides the primary extent size, if a primary extent
size has been previously set. BIM-EPIC calculates the primary extent size
based on:
record length
estimated number of records
block size
track/block capacity of the selected volume
ALR allows you to migrate from one device type to another without
changing the allocation size.
ALR is valid only for sequential disk datasets created with a DTFSD.
