The GENESIS Micro Focus EXTFH ISAM driver uses direct EXTFH calls to provide
very high performance with SQL access. The Micro Focus EXTFH driver supports
array fields as well as the WHEN XFD qualifier to maintain legacy ISAM files.
The GENESIS Micro Focus EXTFH driver
is only available from Micro Focus.
Included with the driver is a GENESIS dictionary
maintenance utility. GENESIS relies upon several
dictionary tables to keep track
of the EXTFH ISAM file layouts, including keys. The utility initializes
the GENESIS dictionary and can also read the Micro Focus XFD definitions to
existing files. This is typically done once assuming that the XFD file
have been kept in sync with the actual EXTFH files. New definitions can be
added and existing ones modified dynamically.
