OpenROAD Application Requirements
An OpenROAD application must meet the following requirements for 4GL procedures to be called remotely through the OpenROAD Server interface. An OpenROAD application must:
• Be an application image that is accessible in the installation where the OpenROAD Server runs. See Application Image.
• Have a ghost frame as the application's starting component (which can have an empty script). See Ghost Frame.
• Be non-interactive, meaning that it must not invoke any graphical user interface (GUI) components. See Non-interactive 4GL Procedures.
• Be able to manage state appropriately when used in shared servers. See How You Can Manage State in Private and Shared Servers.
• Be prepared to handle any necessary cleanup when notified of a shutdown. See Shutdown Notification.
