The SUMSIZE= system
option affects the MEANS, OLAP, REPORT, SUMMARY, SURVEYFREQ, SURVEYLOGISTIC,
SURVEYMEANS, and TABULATE procedures.
Proper specification
of SUMSIZE= can improve procedure performance by restricting the swapping
of memory that is controlled by the operating environment.
Generally, the value
of the SUMSIZE= system option should be less than the physical memory
available to your process. If the procedure that you are using needs
more memory than you specify, the system creates a temporary utility
file.
If the value of SUMSIZE
is greater than the values of the MEMSIZE option and the REALMEMSIZE
option, SAS uses the values of the MEMSIZE option and REALMEMSIZE
option.
