DBAMNU Parameters PAG_SIZ
You may specify the minimum size of a database page.
The value must be an integer between 1 and 63.
It is recommended that the buffer size be a multiple of the
minimum page size. Where different page sizes are or may
be used, the buffer size should be a multiple of each page size.
As a result, the following page size sets are suggested:
Minimum Page
Size Buffer Size Page Sizes
Note that for page sizes of between 32 and 63 blocks the
buffer size should be the same size as the page size.
