FILEBLKSIZE(device-type)=value
|
- device-type
- specifies any valid specific device number,
as well as DASD, DISK, OTHER, SYSOUT, TAPE, and TERM.
- DASD or DISK
- sets values for the device types 2301, 2303,
2305-1, 2305-2, 2311, 2314, 2321, 3330, 3330-1, 3340, 3350, 3375, 3380, 3390,
and 9345.
- OTHER
- specifies the value that SAS uses when it
is unable to determine the exact device type.
- SYSOUT
- sets values for SYSOUT data sets.
- TAPE
- sets values for the 2400, 3400, 3480, 3490E,
and 3590 device types.
- TERM
- sets values for data sets directed to the
terminal.
- value
- specifies the default block size. Valid
values are
- number
- specifies the block size that SAS is to
use for the device.
- OPT
- tells SAS to choose an optimum block size
for the device.
- MAX or FULL
- tells SAS to use the maximum permitted block
size for the device.
- HALF, THIRD, FOURTH, or FIFTH
- tells SAS to use the largest value that
results in obtaining two, three, four, and five blocks per track, respectively,
(if a disk device) or the maximum permitted block size divided by two, three,
four, and five, respectively (if not a disk device).
- MIN
- same as FIFTH above.
The minimum value for FILEBLKSIZE(device-type)= is 5 and the maxmimum is 32,760.
