SAS(R) 9.1.3 Companion for z/OS

Details
System Options under z/OS VERBOSE System Option 523
UTILLOC=’ALLOC UNIT(DISK) UCOUNT(2) CYL SPACE(20,100)’
UTILLOC=’/dept/prod/utility’
UTILLOC=(’ALLOC UNIT(SYSDA) UCOUNT(2) CYL SPACE(15,15)’)
UTILLOC=(’ALLOC UNIT(SYSDA) VOL(SCR001) CYL SPACE(15,15)’,
’ALLOC UNIT(SYSDA) VOL(SCR002) CYL SPACE(15,15)’)
UTILLOC=(’/dept/prod/utility1’, ’/dept/prod/utility2’)
UTILLOC=(’ALLOC UNIT(DISK) CYL SPACE(20,100)’,
’/dept/prod/utility’)
The following parameters must be specified on the ALLOC command:
3 UNIT
3 TRACKS, CYL, or BLOCK
3 SPACE(primary[,secondary])
One or more of the following options can be also specified on the ALLOC command:
3 UCOUNT(number of devices)
3 VOL(volser [,volser...])
3 STORCLASS(storage class)
3 MGMTCLAS(management class)
3 DATACLAS(data class)
Note: UCOUNT is recommended instead of VOL. R
The ALLOC command options listed above have the same syntax and meaning as
when specified on the TSO ALLOCATE command. See the IBM documentation about
the ALLOCATE command for more information.
An ALLOC command can be specified as a utility file location even in the batch
environment. It is not necessary to be running SAS under TSO when you specify an
ALLOC command as a utility file location.
When you specify multiple utility file locations, they are generally used in a
round-robin fashion by SAS applications. For applications that use multiple utility files
at once, it might therefore improve performance to specify locations that have separate
I/O paths (such as locations on different DASD control units).
Unique, system-generated names are used for each utility file required by SAS. This
allows multiple distinct utility files to be in use at one time. It is not possible to specify
the data set name to be used for the utility files.
The utility files required by some applications might exceed the size of a z/OS disk
volume. To allocate multiple volumes for a utility file, specify UCOUNT(n) where n is
the maximum number of volumes. Or, specify an SMS data class (with the DATACLAS
option), which in turn specifies a volume count greater than one. Specifying an explicit
list of volumes with the VOL option is not recommended for multivolume utility files.
The utility files specified with the UTILLOC option reside in regular format
sequential data sets. Extended format sequential data sets are not currently supported.
