CATCACHE=n | hexX | MIN | MAX

n

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.

hexX

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 hexadecimal characters (0-9, A-F), and then followed by an X. For example, the value 2dx sets the number of catalogs to keep open to 45 catalogs.

MAX

sets the number of open-file descriptors that are kept in cache memory to the largest, signed, 4-byte integer that is representable in your operating environment.

Note: The recommended maximum setting for this option is 10. [cautionend]

MIN

sets the number of open-file descriptors that are kept in cache memory to 0.

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 the same catalogs.

Note: If MINSTG is in effect, then SAS sets the value of CATCACHE to 0. [cautionend]
