PageSize

VAccess

Sets or returns the page size of the Pervasive PSQL data file.

Setting this property prior to invoking the DdfCreateTable method determines the page size of the resulting data file.

For existing data files, this property returns the page size used by the file. Setting this property for an existing file has no effect.

The range of valid page sizes depends on the file version of the Pervasive PSQL data file:

512 bytes to 4,096 bytes for file versions prior to 9.0 (a multiple of 512 bytes up to 4,096 bytes)

512; 1,024; 1,536; 2,048; 2,560; 3,072; 3,584; 4,096; or 8,192 for file version 9.0 (values are in bytes)

1,024; 2,048; 4,096; 8,192; or 16,384 for file versions 9.5 and newer (values are in bytes).

Any operation which causes a new status buffer to be retrieved from the file will reset this value (see Stat).
