Parameter Required? Valid Entry Default
Parameter Definition
AGP Specifies if dataset retention is controlled by the
Automatic Generation Purge feature.
ALR Specifies that disk space allocation for a version is done
on the basis of the number of logical records expected to
be written. Specifying allocation by the number of
logical records overrides the primary extent size
indicated by the EXT parameter, if both parameters are
specified. ALR cannot be used if files are created under
DTFPH conditions (Physical IOCS).
CIZ Specifies the desired control interval size used when
allocating an FBA DASD file. You should avoid this
parameter when using CKD DASD files.The CIZ value
specified will be adjusted to an even multiple of 512. In
addition, CIZ will override reblocking and is mutually
exclusive with BLK. If both parameters are specified for
the same dataset definition, the last parameter specified
will be used.
EXT Specifies the primary extent size in blocks or tracks. The
minimum size is 3 tracks for CKD devices or the value
specified in the CIZ parameter for FBA devices. If the
default extent configuration option (DEFEXT=) is set to
a non-zero value for your installation, you can use that
setting as a default primary extent and omit the EXT
parameter in the EDD definition.
EX2 Specifies the secondary extent size which defaults to
half of the size of the primary extent. The minimum
extent size is three tracks for CKD devices or the value
specified in the CIZ parameter for FBA devices.
POL Specifies a disk pool name if disk versions are to be
created. Only disk pool names defined in the TSIDPOL
macro can be used. If the default disk pool configuration
option is (DEFPOL=) for your installation, you can use
that setting as a default disk pool and omit the POL
parameter in the EDD definition.
