MINPARTSIZE= System Option
Specifies the minimum size that the data component
partitions can be. The value is specified when the SPD Engine data
set is created.
| Valid in: |
configuration file, SAS invocation |
| Default: |
16M |
| Engine: |
SPD Engine only |
Syntax
MINPARTSIZE=n | nK | nM | nG
Required Argument
- n
-
is the size of the
partition in bytes, kilobytes, megabytes, or gigabytes. The maximum
value for the minimum partition size is 2GB–1 or 2047 megabytes.
Restriction:This restriction applies only to 32–bit hosts
with the following operating systems: z/OS, Linux SLES 9 x86, and
the Windows family. In SAS 9.3, if you create a data set with a partition
size greater than or equal to 2 gigabytes, you cannot open the data
set with any version of SPD Engine before SAS 9.2. The following error
message is written to the SAS log: ERROR: Unable to
open data file because its data representation differs from the SAS
session data representation.
Details
Specifying MINPARTSIZE=
sets a lower limit for the partition size that can be specified with
the PARTSIZE= option. The MINPARTSIZE= specification could affect
whether the partitions are created with approximately the same number
of observations. A small partition size means more open files during
processing. Your operating system might have a limit on the number
of open files used.
