MINBUFND: Specifying Minimum Target BUFND

Default: STRNO+1

You can guarantee that you have at least (value) data buffers by specifying a value for MINBUFND. Dynamic buffering selects at least MINBUFND data buffers, unless this value exceeds MAXBUFSP. Specify as:

MINBUFND=value

The SYSTEM default applies to any LEVEL selector that does not specify MINBUFND.

If you do not specify a SYSTEM default MINBUFND, (strno+1) is used as MINBUFND. If your MINBUFND is less than this value, it is overridden, because strno+1 is the minimum allowable value for any NSR OPEN. (LSR requires a minimum of 3 buffers for each size buffer in the pool, regardless of the number of files/index levels, and so forth.)
