Assumptions

These tutorials are written from the perspective that all of the following is true. Specific instructions for setting up your environment to adhere to these assumptions is found in the Before you begin a tutorial section that follows:

  • Windows File Explorer is set to show file names and extensions.
  • You are running the latest version of Micro Focus Enterprise Developer, which has been installed on your local machine using default installation settings.
  • You have installed and can access Amazon Aurora PostgreSQL or Amazon RDS for PostgreSQL.
  • The Eclipse IDE is started on your local machine, and the appropriate Perspective and View are open..
  • You have addressed all of the items in the Before you begin a tutorial section below.

Before you begin a tutorial

Install Amazon Aurora PostgreSQL or Amazon RDS for PostgreSQL (version 14.3 or later)
To complete any of the HCOPG tutorials, you must have either Amazon Aurora PostgreSQL or Amazon RDS for PostgreSQL installed. For information on supported versions, see the HCO for PostgreSQL (HCOPG) section of the Database Management Systems (DBMSs) topic.
Set Windows File Explorer options
These tutorials assume that your Windows File Explorer options are set to use the Details layout, and to show file name extensions. See your Windows documentation for more information.
Start Enterprise Developer
Start Enterprise Developer using the default workspace, which is %USERPROFILE%\eclipse-workspace. If you need instructions to get Enterprise Developer started on your local machine, see To start Enterprise Developer.
Open the Team Developer Perspective and Application Explorer View in Eclipse
When you start Enterprise Developer for the first time, the Team Developer perspective starts automatically by default, and shows the Application Explorer view. If this is not the case, open the Team Developer perspective as follows:
  1. From the Eclipse IDE, click Open Perspective Open Perspective.
  2. On the Open Perspective dialog box, select Team Developer (default), and then click Open.

In addition, the Enterprise Development Projects system should be loaded in the Application Explorer view. To confirm this:

  • In the Application Explorer view, you should see the Enterprise Developer system. If the system is not shown, to load it:
    1. Right-click in the Application Explorer view, and then click Add System(s).
    2. In the Add System(s) dialog box, select ED System and click OK.
    3. Expand the top-level Enterprise Developer entry in the Application Explorer view.
    4. Right-click Enterprise Development Projects; then click Load Application.
  • Otherwise, expand the Enterprise Developer system. An entry titled Enterprise Development Projects should appear indicating that the system is loaded.
Set Eclipse to build automatically
By default, the Eclipse Build Automatically option is turned on, which means that Eclipse builds a project automatically each time a change is made. To ensure that this Build Automatically is turned on:
  1. From the Eclipse Main Menu, click Project.
  2. Do one of the following:
    • If the Build Automatically menu option has a check mark to its left, it is already turned on. No further action is required.
    • If the Build Automatically menu option does not have a check mark to its left, click the option to turn it on.

Sequence

You must work through Tutorial: Create and Load the HCO_Test Database before proceeding to an application migration tutorial. However, the two application migration tutorials are not interdependent and may be done in any order:
