Configuring TERM Objects
10 to 15 operator terminals monitor the system using several different information-
gathering Pathway applications.
A Pathway application can support up to 4095 configured TERM objects. Thus, it is
often appropriate to use TERM objects for large networks of terminals dedicated to a
single application. A high-volume application that includes many devices not dedicated
to a specific application must be coded to dynamically add and delete TERM objects as
needed when such devices access the application.
Configuring TERM Objects
For each input-output device or process you want to configure explicitly, you must
define and add a TERM object by using the SET TERM and ADD TERM statements.
ATERM object runs as a thread in the TCP, which can handle many such TERM
objects concurrently.
For example, consider a PATHMON environment that runs a single order-processing
application on 100 application terminals. Whenever users begin to use the application,
their terminals typically display the logon or menu screen for the application, as
presented by the initial screen program. The users can use only this application; they
cannot access other software. To support this system, you would need to configure 100
TERM objects—one for each terminal.
This subsection provides brief definitions of the required and optional attributes you can
configure for a TERM object, gives an example of setting these attributes, and then
describes special considerations for some of the individual attributes.
For the complete syntax of the SET TERM statement, including descriptions of all the
attributes you can set for a TERM object, refer to SET TERM
on page 10-75. For the
syntax of the ADD TERM statement, refer to ADD TERM on page 10-13.
To configure a TERM object, you must specify the following attributes with the SET
TERM statement:
•
INITIAL specifies the name of the first screen program that runs on the device or
process when the TERM object is started.
This is the name specified in the PROGRAM-ID sentence of the Identification
Division in a SCREEN COBOL program.
•
TCP specifies the name of the TCP template for the TCP that controls the screen
program and oversees communication between the screen program and the input-
output device or process.
In addition to the required attributes, other, optional ones can be selected:
•
FILE specifies the name of the input-output device or process that the TERM object
controls.
•
WEIGHT gives a number specifying the relative amount of work that the terminal is
expected to perform.
•
GROUP allows you to specify a logical name for a group of terminals that you want
to manage as a group. When you have configured your TERM objects with group
