Approximate allocated size of the
data set, in units of 1024 bytes. For multivolume data sets, this
is the size of the data set across all volumes on which it resides. The
size calculation is based on a 2KB blocking factor for any given DASD.
The calculation gives only an estimate of the size. If your data sets
use a blocking factor other than 2048 bytes, the space allocated for
your data set might be larger or smaller than is needed.

Number of days since the data set
became eligible for migration. This field can contain a negative value
if DAYS(0) is specified on the MIGRATE volume command for an SMS-managed
volume and for SMS and non-SMS data sets being processed for extent
reduction. In both cases, the negative value represents the number
of days until the data set is eligible for migration, under the normal
criteria. |
