Demonstration Applications

Enterprise Developer provides a number of demonstration applications for HCOPG that illustrate programming techniques and behavior at run time for application migrations using HCO for PostgreSQL. You can access these via the Mainframe Samples Browser. For instructions on how to start the Mainframe Samples Browser, see To start the Samples Browser.

The demonstration files are located in the %PUBLIC%\Documents\Micro Focus\Enterprise Developer\Samples\Mainframe\SQL\hcopg directory.

Each sample application comes with a Readme file to explain how to use the application.

The HCOPG demonstration applications all produce a console log displaying their progress. They all terminate on receipt of an error, after displaying an error message.

HCOPG - Array Insert

Demonstrates how array inserts work with PostgreSQL when using mainframe DB2 syntax.

HCOPG - Function Emulation

Demonstrates how to add math functions to PostgreSQL that emulate standard math functions in DB2.

HCOPG - Labeled Durations

Demonstrates how HCOPG manages DB2 date formats and labeled duration calculations. PostgreSQL does not support labeled calculations directly. HCOPG handles the conversion to PL/pgSQL to emulate DB2 labelled duration syntax.
