Adaptive Server extended-limit capabilities vary by type of table and the
database logical page size. Table 1-2 lists the column and row limits for
allpages-locked (APL) tables.

Database space requirements depend upon the logical page size of the server.If
your database is larger than the minim size listed below, then the
model
minimum size of the database is equal to the
minimum size for each database.
