Complete the following fields:

New Dataset Name

Identifies the new data set name. This value is populated with the value from the Output Extract Layout PDS data set's name.

Volume serial or Generic unit name

Defines the volume where the data set resides. Specify a value for either the Volume serial field or the Generic unit name field.

If multiple volumes are required, set the Specify multi-volume? field to Y.

Note: If both fields are left blank, then a Generic unit name of SYSDA is used.

Management Class

Controls dataset characteristics related to the backup, migration, and retention of the dataset. Updates the 1-to-8-position name of the SMS management class used when allocating the dataset.

Storage Class

Controls the storage hardware used for the dataset. Updates the 1-to-8-position name of the SMS storage class used when allocating the dataset.

Data Class

Controls the attributes of the dataset being allocated. Updates the 1-to-8-position name of the SMS data class used when allocating the dataset.

Space allocation unit

Defines the space allocation unit for the PDS being allocated.

If you enter the first position of one of the valid values, the rest of the Space allocation unit appears in the field.

Values: T (Tracks), C (Cylinders), B (Blocks)

Primary allocation

Defines the primary allocation amount for the PDS. The amount of space allocated in the primary allocation is the specified number of tracks, cylinders, or blocks, depending on the allocation unit.

Secondary allocation

Defines the secondary allocation amount for the PDS. The amount of space allocated in each secondary allocation is the specified number of tracks, cylinders, or blocks depending on the allocation unit.

Directory blocks

Defines the number of directory blocks you want. The Generate Extract file layouts output file must be a PDS, so a value of zero is invalid.

Record format

Identifies a system-generated record format. This is a protected field and cannot be updated.

Record length

Identifies a system-generated record length. This is a protected field and cannot be updated.

Block size

Defines the block size for the PDS being allocated.

For variable blocked or fixed blocked files, the Block size field can be empty or contain zero to allow the system to calculate the optimum block size.

Expiration date

Defines the expiration date in YYYYMMDD format if the PDS can be deleted after a certain date.
