Syntax |
CATCACHE=n | hexX | MIN | MAX | |
specifies any integer greater than or equal to 0 in terms of bytes. If n > 0, SAS places up to that number of open-file descriptors in cache memory instead of closing the catalogs.
specifies the number of open-file descriptors that are kept in cache memory as a hexadecimal number. You must specify the value beginning with a number (0-9), followed by an X. For example, the value 2dx sets the number of catalogs to keep open to 45 catalogs.
sets the number of open-file descriptors that are kept in cache memory to 0.
sets the number of open-file descriptors that are kept in cache memory to the largest, signed, 4-byte integer representable in your operating environment.
Tip: | The recommended maximum setting for this option is 10. |
Details |
Use the CATCACHE= system option to tune an application by avoiding the overhead of repeatedly opening and closing the same SAS catalogs.
