-CATCACHE n | nK | MIN | MAX

-
n | nK
-
specifies the number of open-file descriptors
to keep in cache memory in multiples of 1 (n)
or 1,024 (nK). You can specify decimal values
for the number of kilobytes. For example, a value of 8
specifies 8 open-file descriptors, a value
of .782k
specifies 801
open-file descriptors, and a value of 3k
specifies 3,072 open-file descriptors.
If n > 0, SAS places up
to that number of open-file descriptors in cache memory, instead of closing
the catalogs.
-
MIN
-
sets the number of open-file descriptors
that are kept in cache memory to 0.
-
MAX
-
sets the number of open-file descriptors
that are kept in cache memory to 32,767.
By using the CATCACHE system option to
specify the number of SAS catalogs to keep open, you can avoid repeatedly
opening and closing the same catalogs.
