Description

The DAUTOINC parameter sets the number of unused pages in addition to reserved pages (DPGSRES) that must be maintained in Table D.

Usage

Setting DAUTOINC to a non-zero value indicates that the file’s Table D can be automatically increased when the file is full due to a lack of space in Table D. An increase is done in the amount required to keep DAUTOINC unused pages and DPGSRES reserved pages or the number of pages in the free space, whichever is smaller.

Unused pages for Table D are calculated as the difference between the number of pages in Table D (DSIZE) and the number of used Table D pages (DPGSUSED). The minimum value of DAUTOINC is 0; the maximum is 16777216.

You can implement the DAUTOINC parameter for ordered, entry order, sort key, and hash key files created by Model 204 V6R1.0 and later, and you can view it.
