Syntax

CBUFNO=n| nK | nM | nG | MIN | MAX | hex

Syntax Description

n | nK | nM | nG
specifies the number of extra page buffers in terms of bytes, kilobytes, megabytes, or gigabytes, respectively.

MIN
sets the number of extra page buffers to 0, and requires SAS to use a default value.

MAX
sets the number of extra page buffers to 20.

hex
specifies the number of extra page buffers as a hexadecimal number. This number must be followed by an X.


Details

The CBUFNO= option is similar to the BUFNO= option that is used for SAS data set processing.

Increasing the value for the CBUFNO= option may result in fewer I/O operations when your application reads very large objects from catalogs. Increasing this value also comes with the normal tradeoff between performance and memory usage. If memory is a serious constraint for your system, you probably should not increase the value of the CBUFNO= option. This is especially true if you have increased the value of the CATCACHE= option.

Operating Environment Information:   The syntax that is shown here applies to the OPTIONS statement. On the command line or in a configuration file, the syntax is specific to your operating environment. For details, see the SAS documentation for your operating environment.  [cautionend]
