2.3.3 MCF message-exchange configuration using the Extended Presentation facility

The MCF message-exchange configuration enables communication using the Extended Presentation facility. Using this facility, operations such as printing forms and displaying screens on a workstation or PC can be performed by UAP processes in an OpenTP1 system.

The Extended Presentation facility uses TP1/NET/XMAP3 for communications. As a mandatory requirement, the other machine communicating with the OpenTP1 system node must have the program product XP/W (if a workstation) or XP/P (if a PC) to provide the required GUI-based presentation functionality. There is no need to create a special program for the workstation or PC to serve as the client UAP that requests services in the OpenTP1 system.

Figure 2-4 illustrates the use of the Extended Presentation facility in an MCF message-exchange configuration.

The main features of the Extended Presentation facility are described below.

Organization of this subsection
(1) Screen data operations using message exchange
(2) Data operations in a top-class GUI environment
(3) System configuration matched to the specific processing configuration

(1) Screen data operations using message exchange

With the Extended Presentation facility, TP1/NET/XMAP3 links with XMAP2/W to perform mapping between physical and logical maps.

When you create a UAP, you do not need to be aware of the screen mapping. Nor do you need to create any special messages to display the data. You can create a message-exchange UAP in the same manner as when handling logical messages in ordinary message exchange.

(2) Data operations in a top-class GUI environment

With XP/W or XP/P, you can perform GUI-based operations that make the most of your workstation or PC's excellent presentation functionality. A variety of data operations can be performed from the GUI-based interface.

(3) System configuration matched to the specific processing configuration

XP/W and XP/P both use a client/server system. This means that you can build a system conforming to the optimal configuration for application processing between the OpenTP1 system and the workstations or PCs.

For details on TP1/NET/XMAP3 see the manual OpenTP1 Protocol TP1/NET/XMAP3. For details on the products XP/W, XP/P, and XMAP2/W, see the manual XP/W and the Extended Mapping Service 2/Workstation XMAP2/W DESCRIPTION/USER'S GUIDE.
