COBOL85^SET^SORT^PARAM^VALUE and
COBOL_SET_SORT_PARAM_VALUE_
If subsort-or-file-number is specified, SEGMENT applies to the
indicated subsort.
If subsort-or-file-number is 0, SEGMENT applies to the
distributor/collector process.
If the param-value associated with SUBSORT-COUNT is 0 or not specified,
SEGMENT applies to the normal sort, and subsort-or-file-number must
be omitted or 0.
°
SUBSORT-COUNT
specifies the number of parallel sorts that FastSort is to use to improve
performance.
subsort-or-file-number must not be specified or must be 0. An error
occurs if SUBSORT-COUNT has the value 1.
°
SYSTEM
specifies the system on which the sorting is to occur.
A value other than -1 specifies that a particular other system will be used
(which may result in very poor performance).
subsort-or-file-number must not be specified or must be 0.
If the param-value associated with SUBSORT-COUNT is greater than 1,
SYSTEM is ignored (the current system is used).
Allowable Value for
param-value Meaning
0 (default) FastSort uses normal, non-parallel sort.
2 - 8 FastSort uses parallel sort, and the value of param-value
is the number of processes to be used. (A parallel sort
might be faster, but it uses more system resources. In a
busy system, this might cause an overall loss in system
throughput.)
Allowable Value for
param-value Meaning
-1 (default) Sorting occurs on the current system.
valid system number Sorting occurs on the system specified by param-value.
