Allocate data space (S)

The Allocate dataspace function (option S) allocates VSAM space on a direct-access storage device (DASD). This option is valid only for VSAM catalogs.

For VSAM (non-ICF) catalogs, dataspaces may be allocated on Direct Access devices to allow sub-allocation of VSAM data sets. All objects cataloged in ICF catalogs must be unique and therefore do not use a dataspace.

To allocate a VSAM dataspace in a VSAM catalog, fill in the following fields of the VSAM utilities panel VSAM Utility Screen:

Enter S in the select option field.
Enter a volume serial number.
Set processing option to O (online) or B (Batch).
Enter a Catalog Name if the volume is not owned by the master catalog and a Catalog Password if the catalog is password protected.

When you press Enter, File-AID displays the Allocate New VSAM Space screen, as shown in the following figure.

Field Descriptions

Volume serial

Volume serial that was specified on the VSAM Utility screen. Leave blank to allow SMS to select an eligible volume. Eligibility is determined by the "UNIT" information in your user entry in the TSO "User Attribute Dataset" (UADS).

Important

In some situations you can only enter eligible volumes even when you specify the volume serial. Other times you can enter any mounted volume. This is an installation option.
The volume selected must be owned by a catalog to be eligible for space. If it is not, the owner bit will be turned on.

Space allocation for space component:

Units

Specify one of following storage unit type values:

TRKS - Tracks
CYLS - Cylinders
RECS - Records.

Primary

Specify a value in the specified units.

Secondary

Specify a value in the specified units.

Record size

If the value in the Units field is RECS, specify a value in this field. Any valid number from 0 - 32600 is valid.

To catalog in other than the system catalog:

Catalog name

If the default system catalog is not used, a name must be specified in this field.

Catalog password

If the catalog is password protected, enter the password. If it has not been entered but is necessary, you will be prompted for it.

Press Enter to allocate the space, or use END to cancel the allocation. When the allocation is complete, File-AID displays the message: SPACE ALLOCATED in the upper-right corner of the VSAM Utility screen.
