Configuring TERM Objects
names, you can perform management operations on an entire group of terminals
with a single PXMCOM command.
•
BREAK specifies whether the TCP accepts the Break key function for its terminals
running in conversational mode.
•
DIAGNOSTIC specifies whether diagnostic screens are displayed to inform the
terminal operator when an error condition or termination occurs.
•
TYPE specifies the type of device on which the TERM object runs.
For example, suppose you want to add two physical terminals, with device names
$FRED and $SAM, and you want to control them through TERM objects named
TERM-007 and TERM-008, respectively. These TERM objects will run as threads in
TCP named TCP-PRIME, and upon activation, enter a screen program named
MAIN-MENU. The terminals are T16-6530 terminals. Terminal $FRED typically
generates 30 transactions per hour; Terminal $SAM typically generates 100 transactions
per hour. You can define and add these TERM objects by using the following
PXMCFG statements:
SET TERM INITIAL MAIN-MENU
SET TERM TCP TCP-PRIME
SET TERM TYPE T16-6530:0
SET TERM WEIGHT 30
ADD TERM TERM-007, FILE $FRED
SET TERM WEIGHT 100
ADD TERM TERM-008, FILE $SAM
Assigning the Device or Process Name
The FILE attribute specifies the name of the input-output device or process that the
TERM object is to control. This can be the name recognized by TACL for a terminal or
other physical device. Alternatively, it can be the name of a process that handles work
such as front-end processing or terminal emulation.
If you do not specify this attribute in your configuration, you must specify it in a
PXMCOM CONTROL TERM command before you can perform any operations (other
than INFO commands) on the TERM object. It is recommended that you specify this
attribute in PXMCFG unless you intend this terminal to be a dummy terminal, defined
to provide for future expansion of your Pathway/XM environment.
Setting Terminal Weights
PXMCFG assigns terminals to TCP processes based on the relative amount of work that
each terminal generates. PXMCFG uses the WEIGHT attribute values of the TERM
objects in its automatic balancing of terminal workload. Therefore, it is highly
recommended that you specify a value for this parameter.
The WEIGHT attribute gives a number (an integer from 1 to 32768) specifying the
relative amount of work that the terminal is expected to perform. You can specify that
number as any meaningful value, as long as you use the same definition for all terminal
weights. For example, you could assign each terminal a weight value equal to the
