Description

The number of unused pages to maintain in Table B

Usage

Setting of BAUTOINC to a non-zero value indicates that a file’s Table B may be automatically increased when the file is full due to a lack of space in Table B. An automatic increase occurs after comparing the following and using the smallest number:

  • The value of BAUTOINC
  • The number of pages in the free space
  • The number of pages that can be added to Table B without changing the number of the file’s segments

The number of unused pages to maintain for Table B is calculated as the difference between the number of pages in Table B (BSIZE) and the highest Table B page used (BHIGHPG). The minimum value of BAUTOINC is 0; the maximum is 16777216.

You can view the BAUTOINC parameter and can implement it for unordered, entry order, and sort key files created in Model 204 V6R1.0 or later. BAUTOINC is not implemented for hash key files.
