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.

Details

By using the CATCACHE= system option to specify the number of SAS catalogs to keep open, you can avoid the repeated opening and closing of the same catalogs.

If SAS is running on an z/OS server and the MINSTG system option is in effect, SAS sets the value of CATCACHE to 0.
