Abstract

This article describes a method to eliminate the overhead of GDDM panel processing when using OfficeVision*/MVS* (OV/MVS) with a DOS workstation. When using a DOS workstation with OV/MVS, all data is passed to the workstation using LU 2 protocols. For the display of end user panels, we build the map on the host using GDDM, and send the entire data stream to the PC. This results in ineffective utilization at the host by wasting system resources to perform the data mapping, when the workstation could perform this task.

Enhance Display Mapping for MVS and DOS Workstation

      This article describes a method to eliminate the overhead
of GDDM panel processing when using OfficeVision*/MVS* (OV/MVS) with
a DOS workstation. When using a DOS workstation with OV/MVS, all data
is passed to the workstation using LU 2 protocols. For the display of
end user panels, we build the map on the host using GDDM, and send
the entire data stream to the PC. This results in ineffective
utilization at the host by wasting system resources to perform the
data mapping, when the workstation could perform this task.

      In order to more effectively utilize the OV/MVS product with a
DOS workstation, APPC (LU 6.2) should be utilized for the workstation
to host connection. Instead of OV/MVS performing the data mapping
using GDDM, an APPC conversation can be used to pass the fields of
the map in a logical record to the workstation. OV/MVS would build a
record containing only the contents of modifiable fields and transmit
this to the workstation. Upon receipt of the record from MVS, the
workstation would then build the panel to be displayed, placing the
received data from MVS on its map, and display the panel to the end
user. When the user has entered information onto a panel, the
workstation would then allocate a conversation to OV/MVS, build a
logical record, and send only the contents of modifiable fields back
to the host. Instead of having transmitted an entire map (up to 1980
bytes of data), only the port...
