A percentage of the current Table B size (<var>[[BSIZE_parameter|BSIZE]]</var>), Table D (<var>[[DSIZE_parameter|DSIZE]]</var>), and Table&nbsp;X (<var>[[XSIZE_parameter|XSIZE]]</var>) by which each table can be increased dynamically as a result of automatic increase.
==Usage==
DEFINCP helps to avoid shutting down a file to increase its Tables B, D, and/or X. The amount of the increase for Table B is also limited by the current number of segments in the file, if MAXINCBP is not set.
==Example==
If a file has 100,000 Table B pages and DEFINCP is set to 10, and Table B fills up, the size of Table B will increase to 110,000; then 121,000; then 133,100 pages and so on. The amount of increase is subject to FREESIZE and MAXINCBP restrictions.

Description

A percentage of the current Table B size (BSIZE), Table D (DSIZE), and Table X (XSIZE) by which each table can be increased dynamically as a result of automatic increase.

Usage

DEFINCP helps to avoid shutting down a file to increase its Tables B, D, and/or X. The amount of the increase for Table B is also limited by the current number of segments in the file, if MAXINCBP is not set.

Example

If a file has 100,000 Table B pages and DEFINCP is set to 10, and Table B fills up, the size of Table B will increase to 110,000; then 121,000; then 133,100 pages and so on. The amount of increase is subject to FREESIZE and MAXINCBP restrictions.
