CATCACHE= System Option
under Windows UNIX
OpenVMS z/OS
|
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 an X. For example, the value 2dx sets the number of catalogs to keep open to 45
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 the largest, signed, 4-byte integer
representable in your operating environment.
Tip: |
The recommended maximum setting for this
option is 10. |
Use the CATCACHE= system option to tune
an application by avoiding the overhead of repeatedly opening and closing
the same SAS catalogs.
- CAUTION:
- When using both the CBUFNO= and CATCACHE=
options, if one of the option's value is set higher than zero, the other option
must be set to zero.
