Implementing TPFDF is essentially the same process as implementing any new
application program for the TPF system or ALCS environment. It consists
of:
- Installing TPFDF programs
- Installing TPFDF macro definitions
- Adding records to the database for TPFDF use.
See TPFDF Installation and Customization for more
information.
There are also some implementation considerations that are specific to
TPFDF. These include:
- Appointing a TPFDF database administrator with experience in designing and
implementing databases. The role of the database administrator
includes:
- Assisting the application programmer in designing a database to meet the
requirements of the application program
- Advising the application programmer about how to code TPFDF macros for
maximum performance
- Acting as a coordinator for system and application programmers in
implementing the database.
- Defining procedures to design, implement, and manage TPFDF files.
These procedures include:
- Defining the administrative process for developing the TPFDF database
- Clarifying application programmer, system programmer, and database
administrator responsibilities for this process.
- Assessing database migration options. These include:
- Migrating the entire database to a TPFDF database
- Retaining a traditional database for existing application programs while
implementing a TPFDF database for new application programs
- Writing new application programs and modifying existing application
programs to use both traditional and TPFDF databases.
TPFDF can operate in a multiprocessor environment. TPFDF
supports:
- The loosely coupled facility of the TPF High Performance Option (HPO)
feature
- The multiple database function (MDBF) of the TPF HPO feature.
